CHAP. II. Of the parts of this Ioynt in generall.
THE proper parts of the whole Hand taking it in the large acception of the Ancients, are beside the common parts which we pretermit, the Vessels, the Muscles and the Bones. By the Vessels I vnderstand the Veines, the Arte∣ries * 1.1 and the Nerues. The Veines which are deriued through this whole member doe arise all from the Axillary branch: and there are two; the first passeth along on the inside, the other on the out side of the arme. That on the inside is called Basilica, that on the out side is called Cephalica. The Basilica Hippocrates calleth Ve∣nam internam the inward voine, Others call it Hepatica & Iecoraria, that is, the Liuer-veine. * 1.2 And it is ordinarily deuided into a deeper and a shallower. The deeper climing ouer the axillary Artery and the third paire of sinnewes passeth along to the bought of the Arme which we commonly call the Elbow, and so bestoweth his branches vpon both the bones of the Cubite.
The shallower runneth vnder the skinne to the ioyning of the Cubite with the Arme * 1.3 where it is clouen into two boughes, one of which passeth to the inside of the Cubite, and there is vnited with a branch of the humerary veine, and from that coniunction ariseth the Common veine which they commonly call Mediana or the middle veine; the Arabians cal it the blacke veine. The other bough descendeth along the lower side of the Cubite sprink∣ling * 1.4 the skinne and partes by which it passeth with diuers small branches.
The Cephalica or Head-veine so called, because it is opened in diseases of the Head; * 1.5 Hippocrates calleth externa or the outward veine, because it creepeth along the outside of the arme: others call it Humeraria, (because it passeth thorough the shoulder betwixt the Muscle called Deltoides & the Tēdon or chord of the Pectoral muscle) which falling down vnder the surface of the skin, when it commeth vnto the bought of the Cubite is diuided into two branches: the one borne along obliquely into the inside of the Cubite coupleth it selfe with the braunch of the Liuer-veine, and betwixt them beget the common or mid∣dle veine; the other which is larger descendeth by the Radius almost to the middest there∣of
