Show ofmz HUMAN BODY. Of flat SOLIDS '4. it is dellroyed. The Root is covered with a Membrane which proceeds from that which lines the AU-vmlm. The (276 of the Bonn: is to {upport and bound the relt of the Body. They are covered externally with fine Membranes, call'd Perla/Eta. The Covering of the Skull is called the Pcrz‘rmm‘zmz. 'I‘he PE RIOSTE UM is a doll: Web, which is attached to the Bone by hnall Threads and firnguineous VeflEls, as well as Nerves which enter the Pores of the Bones, and give them a Kind of Sen:‘ibility, and which communicate with the internal Prrioflaum. The Prrioflczmz ferves to l‘ui'tain a great Number of Nerves, which render it very fenlible, and an Infinity offinall capillary VelTels. Thefe Veflels {erve to convey Nourifhment thereto, which is pre- called cong/omm‘afc. Thus the Kidneys which feparate the Urine from the Blood are called conglomerate Glands. Thol'e which ferve to perfed'c the Lymph are termed tong/abate. Thus the Glands of the Groin, the Armpits, and thofe of the Jug/enter}, which have no other Fund'tion, are {aid to be conglobate. Of the VESSELS, fome contain the Blood, others the Lymph, others again {erve to filtrate a particular Fluid. The languineous Veilels are of two Kindsythe A'rteries and the Frizz: : The ARTERIES are elaftic Tubes which proceed from the. Heart, from whence they receive the Blood, and convey it to all {Jarts of the Body. They are of a conical Figure, whole Balls 15 towards the Heart. Thus the more the Fluid is diflant from the Heart, the greater Friétion there is, and the flower is the Motion. This, when the Bones are. broken, ferves to reunite them, and The VE INS are only a Continuation of thelall Dwdrons of the Arteries, and return the fuperfluous Blood to the Heart. T he Arteries have two Motions, the one of Dilatation, the other or replaces the ftibflance that is exfoliated. Contraction ; the firfi is called Dian/.2, the fecond Syjzzo/e; thefe pared and feparated from the Blood by the Pcria cum 5 from whence it is carried and depoiited into the Subf'tance of theBones. _ The CA RT I L A G ES are white, finooth, poliihed, fupple, and elallic Subllanccs, void of Cavities and Marrow. They are not oppoiite h/Iotions form what we call the Pal/e. lo hard as the Bones, and harder than other Parts. They cover the certain Difiances from each other, which hinder the Blood from re- Extremities of the Bones of the Joints ; increaie the Volume and Extent ofthe Bones, and ferve to unite them more clofel r. All turning: back. The Arteries as well as the Veins have Trunlfs at The hall, which are divided into greater and {mailer Branches. the Cartilages of the Joints are covered with a Membrane called finell Ramifications are called mpz'flm‘y Vtfli/y. Peric/Jondrizmz. ' break, and are extended with Difficulty; they {erve to join, to bound and to preferve certain Parts. The MUSCLES are lVlall‘es compofed of reddifh Fibres, which are more long or ihort, and are covered with a proper Membrane. The Extremities of the Mufeles are generally terminated with white, llender, compaét Fibres, which form a round Body called a When they compofe a thin, flat, and broad. Kind of Membrane, it is called an flponem'qfir. The red {oft Part is commonly called FIcflJ. There are two Sorts of fi/fiifl/z's,'fome are hollow, as the Heart,. Arteries, Stomach, Inteitines, and Bladder; their Ufe is to contain and comprefs the Fluids ; the other [Wit/[[35 ferve to move the other Parts of the Body. Their A'fiiozz confil'ts chiefly in contradiing the Fibres, by which they draw the different Parts of the Body, lry means of the Tendons. . The papillary Extrm-iifr: of the Arteries are united to the capil« The L1 GAM ENTS are white, fibrous, clofe compaé'ted Suh- ‘f'tances, more {ripple and more pliant than the Cartilages, hard to Tam/an. The Veins have no {enlible lVlotion, but they contain Value: at Thefe are the principal Infiruments of Nlotion both of the Solids and Fluids. The G LA NDS are little Bodies formed by the interweaving of V'ellels of every Kind, covered with a Membrane, and dellin'd to feparate l'ome particular Fluid from the Nlais of Blood, or to per- lary Extremities of the Veins; the former tranfmit the Blood which erves for Nourilhment, and the latter carry it back to the Heart. The LY M P H A TIC V E 55 E I. s are divided into Arteries and Veins; the Lymphatic Arteries are linall tranfparent Veilels, much finer than the languineous capillary Arteries, from whence they proceed, and convey an aqueous Fluid called Lymp/Ja to all Parts of the Body. The lymphatic Veins are only a Continuation of the Arteries of the lame Name which carry Part of the lymi-L‘a back into the Blood. ‘ The LA. 01‘ E A L V E 35 F. LS are called lymphatic Veins, beeaul'e they receive the white Chyle from the lntefi-rnes, beingr full of . Lynne/2a when that Fluid is alglient. The Caz/ml; deiigneil for Secretions are called _,/i't7‘rtm‘y andrx- :rcr‘c/‘y. 'l‘he/ix‘rrrwy Vie/7515 are hole which leparate a particu: lar Fluid from the Blood, and are thol‘e which principally compote the cmrg/onzerata Glam/r. The camera}; Vii/it's are thole which receive the lecreted Fluid, and depolite it in certain Parts, or carry it out of the Body. The NERVES are white cylindrical Cords, which proceed from the Brain and fpinal Marrow; they are Covered by the Dam fix/afar, and are difh‘ibuted into all Parts or the Body. E 3 They are compoi‘ed |
