[G. the end of the muscle where it becomes tendon, fr. apo, from, + neuron, sinew] bicipital a., a. bicipitalis [TA] radiating fibers from the tendon of insertion of the biceps that form a triangular band passing obliquely across the hollow of the elbow to the ulnar side and becoming merged into the deep fascia of the forearm, thus providing the muscle with an indirect attachment to the subcutaneous border of the ulna. Formerly called “grace Dieu” fascia, it serves to protect the brachial artery and median nerve during phlebotomy of median cubital vein.

SYN: extensor digital expansion. a. of external oblique muscle broad, flat tendinous portion of the external abdominal oblique muscle. The fleshy fibers of the muscle end in the a. along a line descending vertically from the costochondral joint of the ninth rib then turning laterally just below the level of the umbilicus toward the anterior superior iliac spine. The fibers of the a. run medially and inferiorly, contributing to the anterior wall of the sheath of the rectus abdominis muscle and decussating with those of the contralateral a. at the median linea alba. Inferomedially, the a. is attached to the upper border of the pubic symphysis, the pubic crest and pubic tubercle. Between the anterior superior iliac spine and the pubic tubercle, it is thickened and turned under, forming the inguinal ligaments. The portion of the a. attached to the pubic bone forms the superficial inguinal ring by splitting into medial and lateral crura. SEE ALSO: external spermatic fascia, inguinal ligament, lacunar ligament, pectineal ligament, reflected inguinal ligament, superficial inguinal ring, rectus sheath. a. of insertion a tendinous sheet serving for the insertion of a broad muscle. a. of internal oblique muscle broad, flat tendinous portion of the internal abdominal oblique muscle.

Of the portion extending between the costoxiphoid margin and the pubis, the upper two-thirds splits into anterior and posterior laminae at the lateral border of the rectus abdominis muscle to contribute to both the anterior and posterior walls of the sheath of the rectus abdominis muscle as they extend to the midline linea alba. The lower third of the a. does not split but joins the aponeuroses of the external abdominal oblique and transversus abdominis muscles to form the anterior wall of the sheath of the rectus abdominis muscle. The fibers of the portion of the a. contributing to the rectus sheath decussate with those of the contralateral a. in the linea alba. The lowermost portion of the a. blends with the a. of the transversus abdominis muscle to form the conjoint tendon, attaching to the pubic crest and often the pecten pubis, thus forming the posterior wall of the inguinal canal at the superficial inguinal ring.

apoptosis (ap′op-to′sis, ap′o-to′sis)
Programmed cell death; deletion of individual cells by fragmentation into membrane-bound particles, which are phagocytized by other cells. SYN: programmed cell death. [G. a falling or dropping off, fr. apo, off, + ptosis, a falling] Whereas some cells (e.g., cardiac and skeletal muscle fibers, CNS neurons) last a lifetime, others (e.g., epithelial and glandular cells, erythrocytes) have limited life-spans, at the end of which they are genetically programmed to self-destruct, usually to be replaced by others formed by mitosis from surviving cells. Cells in tissue cultures spontaneously undergo a. after about 50 cell divisions. In contrast to cell death caused by injury, infection, or circulatory impairment, a. elicits no inflammatory response in adjacent cells and tissues. Features of a. detectable by histologic and histochemical methods include cell shrinkage, due chiefly to dehydration; increased membrane permeability, with a rise in intracellular calcium and a fall in pH; endonucleolysis (fragmentation of nuclear DNA); and ultimately formation of apoptotic bodies, which are absorbed and removed by macrophages. Besides being due to genetic programming, a. can be induced by injury to cellular DNA, as by irradiation and some cytotoxic agents used to treat cancer. It can be suppressed by naturally occurring factors (e.g., cytokines) and by some drugs (e.g., protease inhibitors). A. typically does not occur in malignant cells. Such cells therefore escape the destiny of their nonmalignant precursor cells and are said to be immortal. Immortalization can occur in various ways. The bcl-2 gene, present in many cancers, directs the production of an enzyme that blocks a. and immortalizes affected cells. Injury to DNA normally triggers a. by activating the p53 tumor suppressor gene, which is missing or mutated in about one-half of all human cancers. Cells that lack this gene can survive chemotherapy and irradiation intended to destroy cancer cells. Failure of a. to occur is also involved in some degenerative diseases, including lupus erythematosus, and may be responsible for cellular damage caused by certain viruses, including HIV.

aporepressor (ap′o-re-pres′er)
