| smooth endoplasmic reticulum | <cell biology> An internal membrane structure of the eukaryotic cell. Biochemically similar to the rough endoplasmic reticulum, but lacks the ribosome binding function. Tends to be tubular rather than sheet like, may be separate from the rough endoplasmic reticulum or may be an extension of it. Abundant in cells concerned with lipid metabolism and proliferates in hepatocytes when animals are challenged with lipophilic drugs. Acronym: SER (18 Nov 1997) |

| smooth-surfaced endoplasmic reticulum | Endoplasmic reticulum that is lacking in ribosomal granules; involved in synthesis of complex lipids and fatty acids, detoxification of drugs, carbohydrate synthesis, and sequestering of Ca++. Synonym: smooth-surfaced endoplasmic reticulum. (05 Mar 2000) |
| stellate reticulum | A network of epithelial cells disposed in a fluid-filled compartment in the centre of the enamel organ between the outer and inner enamel epithelium. (05 Mar 2000) |
| Ebner's reticulum | A network of nucleated cells in the seminiferous tubules. (05 Mar 2000) |
| trabecular reticulum | The network of fibres (pectinate ligaments) at the iridocorneal angle between the anterior chamber of the eye and the venous sinus of the sclera; it contains spaces between the fibres that are involved in drainage of the aqueous humor, and is composed of two portions: the corneoscleral part, the part attached to the sclera, and the uveal part, the part attached to the iris. Synonym: reticulum trabeculare sclerae, Gerlach's valvula, Hueck's ligament, ligamentum annulare bulbi, pectinate ligaments of iridocorneal angle, pillar of iris, trabecular meshwork, trabecular network, trabecular zone. (05 Mar 2000) |
| transitional endoplasmic reticulum | <cell biology> Region at the boundary of the rough endoplasmic reticulum and the Golgi. Transport vesicles are responsible for the transfer of secretory proteins from this part of the rough endoplasmic reticulum to the Golgi system. (18 Nov 1997) |
| endoplasmic reticulum | <cell biology> Membrane system that ramifies through the cytoplasm. The membranes of the endoplasmic reticulum are separated by 50-200 nm and the cisternal space thus enclosed constitutes a separate compartment. The Golgi region is composed of flattened sacs of membrane that together with endoplasmic reticulum and lysosomes constitute the GERL system. See: smooth endoplasmic reticulum, rough endoplasmic reticulum. (18 Nov 1997) |
| endoplasmic reticulum, rough | A type of endoplasmic reticulum (er) where polyribosomes are present on the cytoplasmic surfaces of the er membranes. This form of er is prominent in cells specialised for protein secretion and its principal function is to segregate proteins destined for export or intracellular utilization. (12 Dec 1998) |
| endoplasmic reticulum, smooth | A type of endoplasmic reticulum lacking associated ribosomes on the membrane surface. It exhibits a wide range of specialised metabolic functions including supplying enzymes for steroid synthesis, detoxification, and glycogen breakdown. In muscle cells, smooth endoplasmic reticulum is called sarcoplasmic reticulum. (12 Dec 1998) |
| Kolliker's reticulum | glial cells |
| uveal part of trabecular reticulum | The posterior part of the trabecular reticulum, located between the scleral spur, the ciliary body, and the anterior surface of the iris. Synonym: pars uvealis reticuli trabecularis. (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) |
| anterior limb of internal capsule | The portion of the internal capsule between the head of the caudate nucleus and the putamen; it lies anterior to the genu of the internal capsule. Synonym: crus anterius capsulae internae. (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) |
