| theca interna cone | The conical thickening of thecal cells of an ovarian follicle with its apex pointed toward the surface. (05 Mar 2000) |

| endometriosis interna | <gynaecology> A condition where there is abnormal thickening of the endometrial lining of the uterus, extending into the fibrous and muscular layers. This condition occurs most commonly in women above 30 who have had children. Symptoms include prolonged or heavy menstrual bleeding and painful menses with cramping. Treatment generally includes pain medications and a hysterectomy in select (more severe) cases. Birth control pills may aggravate symptoms. (07 Apr 1998) |
| tunica interna bulbi | Light sensitive layer of the eye. In vertebrates, looking from outside, there are four major cell layers: (i) the outer neural retina, which contains neurons (ganglion cells, amacrine cells, bipolar cells) as well as blood vessels, (ii) the photoreceptor layer, a single layer of rods and cones, (iii) the pigmented retinal epithelium (PRE or RPE), (iv) the choroid, composed of connective tissue, fibroblasts and including a well vascularised layer, the chorio capillaris, underlying the basal lamina of the PRE. Behind the choroid is the sclera, a thick organ capsule. In molluscs (especially cephalopods such as the squid) the retina has the light sensitive cells as the outer layer with the neural and supporting tissues below. See: retinal rods, retinal cones, rhodopsin. (18 Nov 1997) |
| tunica interna thecae folliculi | <embryology> The inner cellular and vascular layer of the vesicular ovarian follicle. There is evidence that the epithelioid cells produce oestrogen and contribute to the formation of the corpus luteum after ovulation. Synonym: theca interna. (05 Mar 2000) |
| facies interna | The internal concave surface of either the frontal or the parietal bone. Synonym: facies interna. (05 Mar 2000) |
| facies interna ossis frontalis | The surface of the frontal bone that contributes to the wall of the cranial cavity. Synonym: facies interna ossis frontalis. (05 Mar 2000) |
| facies interna ossis parietalis | The concave surface of the parietal bone forming part of the wall of the cranial cavity. Synonym: facies interna ossis parietalis. (05 Mar 2000) |
| lamina interna cranii | The inner compact layer of the cranial bones. Synonym: lamina interna cranii. (05 Mar 2000) |
| fovea inguinalis interna | A depression on the peritoneal surface of the anterior abdominal wall between the ridges formed by the inferior epigastric artery and the medial umbilical ligament; it corresponds to the position of the superficial inguinal ring and is the site of a direct inguinal hernia. Synonym: fossa inguinalis medialis, fovea inguinalis interna. (05 Mar 2000) |
| Abernethy's fascia | A layer of subperitoneal areolar tissue in front of the external iliac artery. See: iliac fascia. (05 Mar 2000) |
| anal fascia | The fascia that covers the inferior aspect of the levator ani and coccygeus muscles. Synonym: fascia diaphragmatis pelvis inferior, anal fascia. (05 Mar 2000) |
| antebrachial fascia | It is continuous with the brachial fascia; in the region of the wrist it forms two thickened bands, the extensor and flexor retinacula. Synonym: fascia antebrachii, deep fascia of forearm, fascia of forearm. (05 Mar 2000) |
| arcus tendineus of obturator fascia | <anatomy> A thickened portion of the obturator fascia that extends in an arching line from the pubis posteriorly to the ischial spine and gives origin to part of the levator ani muscle. Synonym: arcus tendineus musculi levatoris ani, arcus tendineus of obturator fascia. (05 Mar 2000) |
| axillary fascia | The fascia that forms the floor of the axilla. It is continuous with the pectoral and clavipectoral fascia anteriorly, with the brachial fascia laterally, and with the fascia of the latissimus dorsi and serratus anterior muscles posteriorly and medially. Synonym: fascia axillaris. (05 Mar 2000) |
| bicipital fascia | Aponeurosis bicipitalis, radiating fibres from the tendon of insertion of the biceps which 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. Formerly called "grace Dieu" fascia, it serves to protect the brachial artery and median nerve during phlebotomy of median cubital vein. Synonym: aponeurosis musculi bicipitis brachii, bicipital fascia, lacertus fibrosus, semilunar fascia. (05 Mar 2000) |
