| lacertus musculi recti lateralis | <anatomy> The part of the tendon of origin of the lateral rectus muscle attaching to the greater wing of the sphenoid bone, lateral to the common tendinous ring; often incorrectly equated to the lateral check ligament of the eyeball. Synonym: lacertus musculi recti lateralis. (05 Mar 2000) |
| lamina anterior vaginae musculi recti abdominis | The portion of the rectus sheath that lies anterior to the muscle, consisting in its upper two-thirds of contributions from the aponeuroses of the external and internal oblique muscles, and in its lower third (below the arcuralt line) of contributions from the aponeuroses of all three muscles of the anterolateral abdominal wall. Synonym: lamina anterior vaginae musculi recti abdominis. (05 Mar 2000) |
| lamina posterior vaginae musculi recti abdominis | The portion of the sheath of the rectus abdominis muscle that lies posterior to the muscle covering only its upper two-thirds; it is formed by contributions from the aponeuroses of the internal oblique and transversus abdominis muscles; its free inferior margin forms the arcuate line; it is deficient below this, the posterior aspect of the muscle being covered only by transversalis fascia and peritoneum. Synonym: lamina posterior vaginae musculi recti abdominis. (05 Mar 2000) |
| linea arcuata vaginae musculi recti abdominis | A crescentic line, not always clearly defined, which marks the lower limit of the posterior layer of the sheath of the rectus abdominis muscle. Synonym: linea arcuata vaginae musculi recti abdominis, Douglas' line, linea saemicircularis, saemicircular line. (05 Mar 2000) |
| atresia folliculi | A normal process affecting the primordial ovarian follicles in which death of the ovum results in cystic degeneration followed by cicatricial closure. (05 Mar 2000) |
| collum folliculi pili | The narrowed part of the hair follicle between the hair bulb and the surface of the skin. Synonym: collum folliculi pili. (05 Mar 2000) |
| stratum granulosum folliculi ovarici vesiculosi | The layer of small cells that forms the wall of an ovarian follicle. Synonym: granular layer of a vesicular ovarian follicle, granulosa, membrana granulosa, stratum granulosum ovarii. (05 Mar 2000) |
| theca folliculi | The wall of a vesicular ovarian follicle. See: tunica externa, tunica interna thecae folliculi. (05 Mar 2000) |
| tunica externa thecae folliculi | <embryology> The external fibrous layer of the theca of a well-developed vesicular ovarian follicle; the cells and fibres are arranged in a concentric fashion. Synonym: theca externa. (05 Mar 2000) |
| 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) |
| folliculi | The pleural of folliculus. (05 Mar 2000) |
| folliculi glandulae thyroideae | <physiology> The small spherical vesicular components of the thyroid gland lined with epithelium and containing colloid in varying amounts. The colloid serves for storage of the thyroid hormone precursor, thyroglobulin. Synonym: follicles of thyroid gland. Origin: L. A small sac, dim. Of follis, bellows (05 Mar 2000) |
| folliculi linguales | Collections of lymphoid tissue in the mucosa of the pharyngeal part of the tongue posterior to the terminal sulcus collectively forming the lingual tonsil. Synonym: lenticular papillae, lingual follicles. (05 Mar 2000) |
