vena arteriosa have three Sigmoides So much then concerning the vessels of the Brest now follow the entrals CAP. VIII Of the Heart OF these there are foure the Heart the Lungs the Wind-pipe and part of the Gullet In the explication of the heart First the Swadler is to bee considered and then the substance of the heart it selfe The Swadler called Pericardium or Capsula cordis is a membrane wrapping in the whole heart having the figure of the same having such distance from the heart and to containe the watrish humour It is perforat in five places for the comming in and going out of the vena cava and for egresse of the other three The substance of it is thicke and firme The outer superficies is fibrous but the inner smooth and slippery It is tyed to the Mediastinum and adjacent parts by sundry fibres It doth cleave firmly to the sinewy circle of the midrife but not so in dogs It hath its beginning from the tunicles which compasse the vessels which proceed from the pleura for between the heart and the pericardium the membrane from the pleura is wanting It containeth a watrish substance not sharpe for the refrigeration and humefaction of the heart As in the cavity of the brest a moysture is found like water and bloud mingled together So from the side of our Saviour pierced water and bloud did flow The Pericardium hath veins from the phrenicae and axillar No arteries appeare because it is neere enough to the heart It hath small nerves from the left recurrent As for the heart the substance of it is compact and firme and full of fibres of all sorts The upper part is called hath a small nerve from the sixt conjugation for feeling but not motion for it moveth of it selfe of all the parts of the body it is the hottest for it is the well spring of life and by arteries communicateth it to the rest of the body The heart hath two motions Diastole and Systole In Diastole or dilatation of the heart the conus is drawne from the basis to draw bloud by the cava to the right ventricle and aire by arteria venosa to the left ventricle In Systole or contraction on the conus is drawne to the basis First that the vitall spirit may be thrust from the left ventricle of the heart into the aorta Secondly that the arteriall bloud may bee thrust into the lungs by arteria venalis Thirdly that the bloud may bee pressed to the lungs in the right ventricle by vena arterialis The parts of the heart are either externall or internall The externall are the eares The eares are annexed to the firme substance of the heart about the basis of it before the mouths of the vessels They are of a nervous substance for strength yet thin and soft for the easier contraction and dilatation the left is thicker than the right When they are distended they are smooth but being contracted they are wrinckled They are storehouses of the heart for they first receive the aire and bloud lest they immediatly rushing into the heart might offend it and they strengthen the vessels These eares are two in number the right which is greatest this is before the vena cava and the left the lesser before the arteria venosa They are called eares not from the office of hearing but from the likenesse they representing the figure of an eare Death approaching when the heart is immoveable they move so we see that a small gale of wind which moveth not the tree moveth the leaves The internall parts of the heart are the ventricles or cavities and the septum The ventricles are in number two the right and the left The right is larger than the left yet the left hath thicker sides and within is more unequall than the right The right ventricle receiveth bloud from the vena cava to be sent by vena arteriosa to the lungs and reacheth not to the conus The left ventricle is not so wide as the right yet the fleshy circumference is thrice as thick as that of the right It doth elaborat the vitall spirit of the blood and aire drawne in by arteria venosa The septum so called because it separateth the right ventricle from the left is that thick and fleshy substance set between the two cavities Riolan will have the matter of the vitall bloud to passe thorow the holes or porosites of it from the right to the left ventricle but that hardly any instrument can shew them First because they goe not straight but wreathed Secondly because they are exceeding narrow in the end He affirmeth that they are more easily discerned in an Oxe heart boiled CAP. IX Of the Lungs Wind-pipe and Gullet AS for the lungs the substance of them in Infants whilest they are in the wombe is red and compact but after birth because they begin to move with the heart by heat and motion this substance beginneth to be more loose and spongious and of a pale yellow colour that they may the more easily rise and fall to receive the aire and expell superfluities The substance of the lungs is covered with a membrane communicated by the pleura for the vessels as soone as they enter into the substance of the lungs they leave the coat which they borrowed of the pleura and leave it for covering of the lungs This membrane is porous to give way to impurities contained in the cavity of the brest to passe thorow the loose substance of the lungs to be discharged by expectoration When the lungs are blowne up they fill the whole cavity of the brest In figure they are like to an Oxes hoofe The outer part is gibbous the inward hollow the lungs are divided into the right and left part each of these hath two lobes seldome three with the which as with fingers they embrace the heart Nature hath ordained this division that if one side of the lungs should be hurt the other might discharge the office The lungs and brest are divided by the benefit of the mediastinum which is a double membrane framed of the pleura for the pleura beginning at the back passeth to the sternum by the sides when it is come to the middle of the sternum it directly from thence passes to the back againe The cavity which the reduplication of the pleura leaveth here is above wider but towards the back narrower and narrower untill the membranes be united Penetrating wounds going no further than this cavity are not deadly The mediastinum is softer than the pleura The lungs are joyned to the sternum by the mediastinum behind the vertebra of the back towards the sides to the pleura by fibres sometimes they are tyed which causeth difficulty of breathing It is joyned to the heart by vena arteriosa and arteria venosa The lungs have three vessels vena arteriosa arteria venosa and trachaea arteria these two marching together have betweene them inserted a branch of the
generation of the animall spirits 2. The lungs draw in by it the aire for the refreshing of the heart and the generation of the 〈◊〉 tall spirits 3. That by it smels might be carried to precessus mammillares 4. By it the braine dischargeth excrements 5. It furthereth the speech 6. It beautifieth the face 7. It parteth the eyes that the one should not see the other which would have hindered the sight It is a defence into them also and staigth the visible species 8. By fleering up it expresseth anger and in the Hebrew tongue is taken for anger CAP. XIII Of the Mouth IT is called Os from the letter O In pronouncing of which it openeth it selfe The mouth that serveth for breathing Secondly for receiving of food Thirdly for speaking and lastly to discharge the excrements of the braine lungs and stomack It beginneth at the lips and reacheth to the throat The parts of it are either externall or internall the externall are labia or the lips from lambo They are in number two to wit the upper and lower they have to further motions thirteen muscles whereof eight are proper and five common to the cheekes and lips The lips are of a fungous substance the skin doth firmly cleave to the muscles They are covered within with a tunicle common to the mouth and stomack And from hence commeth the trembling of the lower lip before vomiting The lips serve first for the conveniency of eating and drinking Secondly for the beautifying of the face if they bee well fashioned Thirdly to containe the spittle in the mouth Fourthly to keepe the gums and teeth from externall injuries Fifthly to keepe the gums and teeth from externall injuries Fifthly to serve for the framing of the speech Sixthly to serve for kissing The conjuction of the lips make the laterall parts of the mouth which are called buccae the cheeks The inner parts of the mouth are these 1. Gingivae or the gums They are fleshy destitute of motion to keepe the teeth in their sockets 2. The teeth which are bony both to chew the meat and to fashion the speech each tooth hath two parts one without the gum called Basis the other within called Radix or the root The root below receiveth a little veine artery and nerve The incisores and canini have but one fang The lower molares have two fangs but the upper molares three In children from the seventh moneth untill two yeeres be compleat twenty teeth come out now one then another Of these teeth some are called incisores the first fore teeth in number foure in each gum some canini adjacent to these on each side one The rest are called molares 3. The third internall part of the mouth is palatum or the roofe of the mouth It is vauted that the aire being repercussed the voice should be the sharper It is wrinckled and rough above the bone that it might more firmly cleave to it and it might the better keepe the meat while it is a chewing 4. And 5. Of the almonds and uvula I have spoken in the discourse of the neck 6. Of the internall parts is the tongue in Latine called Lingua à lingendo from licking The flesh of it is spongious that it might receive the qualities of the sapors and judge of them In figure it is pyramidall The tunicle with the which it is covered proceedeth from the dura mater Veins it hath from the externall jugulars Under the tongue they are called ranulares from their colour The arteries come from the carotides Sinews it hath from the third and seventh paire The muscles which move it are six It is divided into two parts by a line going along it and so in hemiplegia onely one halfe may bee affected Of the ligaments the lower is called fraenum and franulum If it bee extended to the top of the tongue it hindereth sucking in children and from this they are said to be tongue-tyed In this case the ligament is to be cut The tongue hath foure uses 1. It is the instrument of tasting 2. It uttereth the speech 3. It helpeth chewing by gathering of the meat and tossing it to and fro and turning it downe to the stomack 4. It serveth for licking The fourth Book A description of the veins arteries and sinewes of the Lims CAP. I. Of the veins of the Arme. RAmus subclavius or the branch of the vena cava ascending under the cannell bone when it is come to the arme-pit it is called axillaris and it parteth it selfe in two veins the cephalica and basilica The cephalica in beasts doth wholly spring from the externall jugular but in man it receiveth only a spring from the externall jugular Wherfore in diseases of the head it is not without cause opened It passeth thorow the upper and outward part of the arme to the bending of the elbow where it is divided into two branches of the which one joyning with a branch of the basilica makes the mediana Wherefore the slope branches which usually are opened about the bending of the elbow are only branches of the cephalica and basilica which meeting make the median The other branch of the cephalica marching according to the length of the radius reacheth to the hand thorow which it is spred but chiefly that part which is betweene the ring finger and the little finger There the Salvatella is placed which is to be opened in melancholy diseases The basilica passeth thorow the inner and lower part of the arme accompanied with the artery and nerves About its beginning it maketh the thoracica which having three or foure sprigs and passing under serratus major and the subscapular muscle it is tyed to the upper intercostall and about the spina dorsi is inosculat with the twigs of vena sine pari Basilica about the bending of the elbow is divided into that which is called subcutanea and that which is called profunda Profunda the deeper is annexed to the artery about the bending of the elbow not under Then passing betweene the focils it is carried to the hand by the outer part of the ulna The subcutanea or the shallowest branch neere to the bending of the arme being turned off to the outer part of the ulna by the length of it it is carried to the hand The Modiana passed to the inside of the hand by the middle part of the ulna CAP. II. Of the arteries of it RAmus subclavius so called as that of the vena cava when it is come to the arme-pits it is called axillaris It accompanieth the basilica for there is no cephalicall artery Neere to the arme holes it yeeldeth that artery which is called thoracica from thence being carried to the bending of the arme it is parted into two branches which passe to the inner side of the hand for the outside of the hand hath neither muscles nor artery The one of these resting upon the radius is that which is felt about the wrest
