| epithelial reticular cell | One of the many-branched epithelial cell's that collectively form the supporting stroma for lymphocytes in the thymus; believed to produce thymosin and other factors that control thymic function. (05 Mar 2000) |

| juvenile epithelial corneal dystrophy | Epithelial dystrophy characterised by progressive cysts and opacities of the corneal epithelium, with onset in infancy. Inheritance: autosomal dominant with incomplete penetrance. Synonym: Meesman dystrophy. (22 Sep 2002) |
| focal epithelial hyperplasia | Hyperplasia of the mucous membrane of the lips, tongue, and less commonly, the buccal mucosa, floor of the mouth, and palate, presenting soft, painless, round to oval sessile papules about 1 to 4 mm in diameter. The condition usually occurs in children and young adults and has familial predilection, lasting for several months, sometimes years, before running its course. A viral aetiology is suspected, the isolated organism being usually the human papilloma virus. (12 Dec 1998) |
| follicular epithelial cell | <physiology> A cell lining a follicle such as that of the thyroid gland. (05 Mar 2000) |
| laminated epithelial plug | An accretion of epithelia in the external auditory canal. Synonym: laminated epithelial plug. (05 Mar 2000) |
| Fuchs' epithelial dystrophy | Epithelial oedema secondary to endothelial dystrophy of the cornea. (05 Mar 2000) |
| annular part of fibrous digital sheath | One of the two circular fibrous bands of the fibrous sheaths of the fingers and toes attached to the shaft of the proximal and middle phalanges. Synonym: pars annularis vaginae fibrosae, annular pulley, annulus of fibrous sheath, ligamentum annulare digitorum. (05 Mar 2000) |
| annulus of fibrous sheath | One of the two circular fibrous bands of the fibrous sheaths of the fingers and toes attached to the shaft of the proximal and middle phalanges. Synonym: pars annularis vaginae fibrosae, annular pulley, annulus of fibrous sheath, ligamentum annulare digitorum. (05 Mar 2000) |
| anterior layer of rectus abdominis sheath | 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) |
| arcuate line of rectus sheath | 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) |
| axillary sheath | Fibrous neurovascular sheath, formed as an extension of the prevertebral layer of deep cervical fascia through the cervicoaxillary canal, which enclosed the first part of the axillary artery, the axillary vein, and the brachial plexus. (05 Mar 2000) |
| carotid sheath | The dense fibrous investment of the carotid artery, internal jugular vein, and vagus nerve on each side of the neck, deep to the sternocleidomastoid muscle; the layers of cervical fascia blend with it. Synonym: vagina carotica. (05 Mar 2000) |
| rectus sheath | Sheath of the rectus abdominis, formed by the aponeuroses of the three anterolateral muscles of the abdominal wall that split to enclose the rectus and fuse medially to form the linea alba; it consists of an anterior lamina and a posterior lamina, the latter being absent below the arcuate line. See: aponeurosis of external abdominal oblique muscle, aponeurosis of internal abdominal oblique muscle. Synonym: vagina musculi recti abdominis. (05 Mar 2000) |
