Outward, in the head, arms, feet, &c., and have several names.

_Fibrae, Fat, Flesh_.] Fibrae are strings, white and solid, dispersed
through the whole member, and right, oblique, transverse, all which have
their several uses. Fat is a similar part, moist, without blood, composed
of the most thick and unctuous matter of the blood. The [959]skin covers
the rest, and hath _cuticulum_, or a little skin tinder it. Flesh is soft
and ruddy, composed of the congealing of blood, &c.

SUBSECT. IV.--_Dissimilar Parts_.

Dissimilar parts are those which we call organical, or instrumental, and
they be inward or outward. The chiefest outward parts are situate forward
or backward:--forward, the crown and foretop of the head, skull, face,
forehead, temples, chin, eyes, ears, nose, &c., neck, breast, chest, upper
and lower part of the belly, hypocondries, navel, groin, flank, &c.;
backward, the hinder part of the head, back, shoulders, sides, loins,
hipbones, _os sacrum_, buttocks, &c. Or joints, arms, hands, feet, legs,
thighs, knees, &c. Or common to both, which, because they are obvious and
well known, I have carelessly repeated, _eaque praecipua et grandiora
tantum; quod reliquum ex libris de anima qui volet, accipiat_.

Inward organical parts, which cannot be seen, are divers in number, and
have several names, functions, and divisions; but that of [960]Laurentius
is most notable, into noble or ignoble parts. Of the noble there be three
principal parts, to which all the rest belong, and whom they serve--brain,
heart, liver; according to whose site, three regions, or a threefold
division, is made of the whole body. As first of the head, in which the
animal organs are contained, and brain itself, which by his nerves give
sense and motion to the rest, and is, as it were, a privy counsellor and
chancellor to the heart. The second region is the chest, or middle belly,
in which the heart as king keeps his court, and by his arteries
communicates life to the whole body. The third region is the lower belly,
in which the liver resides as a _Legat a latere_, with the rest of those
natural organs, serving for concoction, nourishment, expelling of
excrements. This lower region is distinguished from the upper by the
midriff, or diaphragma, and is subdivided again by [961]some into three
concavities or regions, upper, middle, and lower. The upper of the
hypocondries, in whose right side is the liver, the left the spleen; from
which is denomin
