Anatomists divide the Body into three Regions, or Venters ; the Head ; the Thorax, or Breast ; and the Abdomen, or Belly, absolutely so call'd ; being the lowest Part of the Trunk. 'Tis separated from the Thorax by the Diaphragm, and reaches to the
The Name is Latin, compounded of
ABDUCTOR Auricularis, or of the little Finger, arises from the Annular Ligament, and the third and fourth Bones of the Carpus in the second Rank ; and is inserted externally into the first Bone of the little Finger : it serves to draw that Finger from the rest. See FINGER.
Beasts that chew the Cud are sound to have four Stomachs ; viz. the Rumen, or Magnus Venter or Stomach, properly so call'd, the Reticulum, Omasus, and Abomasus. See RUMINATION, &c.
The Abomasus, popularly call'd the Maw, is the last ; being the Place wherein the Chyle is form'd, and from which the Food descends immediately into the Intestines.
ACROMION, Acromium, in Anatomy, the upper Process of the Omoplate, or Shoulder-Bone. See OMOPLATE.The Word is derived from ἄκρος, extremity, and ὦμος, shoulder, i.e., the Extremity of the Shoulder, and not from Anchor, on account of any similarity in Figure which the Acromion bears to an Anchor, as Dionis has imagined. Some have thought the Acromion to be of a nature different from that of other bones; in regard, during infancy, it appears to be no more than a cartilage, which ossifies little by little, and about the age of twenty years becomes hard and firm, like a common bone. See BONE and OSSIFYING.
ADAMI Pomum, Adam's Apple, in Anatomy, a little prominence in the middle of the Cartilago Thyroidea. See POMUM ADAMI.
ADEPS, in Anatomy, is a type of Fat, found in the Cavities of the Abdomen. See FAT.Adeps differs from the common fat, called Pinguedo, in that it is thicker, harder, and of a more earthy substance.See PINGUEDO.Adeps is much the same as what we call Sevum, Suet, or Leaf. See SEVUM.Adeps is also used by physicians as a general name for fat of either kind.Adeps Anseris (Goose Fat); Adeps Canis (Fat of a Dog); Adeps Hominis (Fat of a Man); Adeps Viperis (Viper's Fat); and Adeps Ursi (Bear's Fat), are all used in medicine, in the quality of Ripeners, or Drawers; as being of a penetrating nature, and thereby suited to dissolve and rarify the tumors, and bring them, as it were, to maturity. See RIPENER.The specific virtues attributed to certain of them do not seem well warranted. See FAT, VIPER, etc.
ADIPOSA, or Adiposa Membrana, in anatomy, is a membrane investing the body, immediately under the cutis;supposed to be the basis of the fat, which is lodged in the spaces between its fibers and in peculiar cells formed herein. See FAT, CUTIS, etc.
Anatomists are divided as to the reality of this membrane;most of the later writers taking it to be no other than the exterior membrane of the Membrana Carnosa or Musculorum Communis. See MEMBRANE, CARNOSA, etc.
