| fibrous capsule of liver | A layer of connective tissue ensheathing the hepatic artery, portal vein, and bile ducts as these ramify within the liver. Synonym: capsula fibrosa perivascularis, perivascular fibrous capsule. Connective tissue capsule surrounding the outer surface of the liver, but continuous with septae of some animals which divide parenchyme into lobule, and with the perivascular fibrous capsule at the porta hepatis. Synonym: tunica fibrosa hepatis, Glisson's capsule. (05 Mar 2000) |

| fibrous capsule of parotid gland | The part of the investing cervical fascia that ensheaths the parotid gland and is fixed above to the zygomatic arch. Synonym: fascia parotidea, fibrous capsule of parotid gland, parotid sheath. (05 Mar 2000) |
| fibrous capsule of spleen | The fibrous capsule of the spleen, containing collagen, elastic fibres, and smooth muscle. Synonym: tunica fibrosa splenis, tunica fibrosa lienis, capsula lienis, tunica propria lienis. (05 Mar 2000) |
| fibrous capsule of thyroid gland | The fibrous sheath of the thyroid gland. Synonym: capsula fibrosa glandulae thyroideae. (05 Mar 2000) |
| lens capsule | The capsule enclosing the lens of the eye. Synonym: capsula lentis, crystalline capsule, lenticular capsule, phacocyst. (05 Mar 2000) |
| lens capsule, crystalline | The noncellular outer covering of the crystalline lens, secreted by the embryonic anterior and posterior epithelium. The embryonic posterior epithelium later disappears. (12 Dec 1998) |
| lenticular capsule | The capsule enclosing the lens of the eye. Synonym: capsula lentis, crystalline capsule, lenticular capsule, phacocyst. (05 Mar 2000) |
| abdominal internal oblique muscle | <anatomy, muscle> Origin, iliac fascia deep to lateral part of inguinal ligament, anterior half of crest of ilium, and lumbar fascia; insertion, tenth to twelfth ribs and sheath of rectus; some of the fibres from inguinal ligament terminate in the conjoint tendon; action, diminishes capacity of abdomen, flexes lumbar vertebral column (bends thorax forward); nerve supply, lower thoracic. Synonym: musculus obliquus internus abdominis, abdominal internal oblique muscle. (05 Mar 2000) |
| anterior intercostal branches of internal thoracic artery | One of the arteries supplying the anterior portions of the intercostal spaces of the thoracic wall. Anterior intercostal arteries 1-6 arise as branches of the internal thoracic artery; 7-11 arise as branches of the musculophrenic artery. Synonym: rami intercostales anteriores, rami intercostalis anteriores arteria thoracica interna. (05 Mar 2000) |
| aponeurosis of internal abdominal oblique muscle | <anatomy> Broad, flat tendinous portion of the internal abdominal oblique muscle. The fleshy fibres of the muscle end in the aponeurosis lateral to the semilunar line. The uppermost portion of the aponeurosis is attached to the outer surfaces and lower borders of the seventh to ninth costal cartilages. 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 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 aponeurosis 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 fibres of the portion of the aponeurosis contributing to the rectus sheath decussate with those of the contralateral aponeurosis in the linea alba. The lowermost portion of the aponeurosis blends with the aponeurosis 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. See: cremasteric fascia, conjoint tendon, rectus sheath. (05 Mar 2000) |
| basal tentorial branch of internal carotid artery | <anatomy, artery> A small branch from the cavernous part of the internal carotid artery to the base of the tentorium. Synonym: ramus basalis tentorii arteriae carotidis internae. (05 Mar 2000) |
| ganglionic branch of internal carotid artery | <anatomy, artery> Branch to trigeminal ganglion; a small branch of the cavernous part of the internal carotid artery to the trigeminal ganglion. Synonym: ramus ganglii trigeminalis. (05 Mar 2000) |
| marginal tentorial branch of internal carotid artery | <anatomy, artery> A small branch from the cavernous part of the internal carotid artery to the free margin of the tentorium. Synonym: ramus marginalis tentorii arteriae carotidis internae. (05 Mar 2000) |
| carotid artery, internal | Branch of the common carotid artery which supplies the anterior part of the brain, the eye and its appendages, the forehead and nose. (12 Dec 1998) |
| vessels of internal ear | Blood vessels of the internal ear, consisting of the labyrinthine artery and its branches and the labyrinthine veins and their tributaries. Synonym: vasa auris internae. (05 Mar 2000) |
