| tympanic labium of limbus of spiral lamina | The lower, long periosteal extension of the limbus laminae spiralis osseae that rests on the basilar lamina of the spiral organ (of Corti). Synonym: labium limbi tympanicum laminae spiralis, tympanic lip of limbus of spiral lamina. Labium urethrae, one of the two lateral margins of the external urethral orifice of the female.

| fibrous lamina | Alternative name for the nuclear lamina, the region lying just inside the inner nuclear membrane. (18 Nov 1997) |
| labiogingival lamina | A band of ectodermal epithelial cells growing into the mesenchyme of the embryonic jaws between the developing lip and the growing gingival elevation; it later opens to form the labiogingival groove. (05 Mar 2000) |
| lamina | Flat sheet, as in basal lamina. (18 Nov 1997) |
| lamina affixa | That part of the medial ependymal wall of the lateral ventricle of the embryonic brain that in later development becomes adherent to the superior surface of the thalamus and thus comes to form the floor of the central part of the lateral ventricle; it covers the thalamostriate and choroidal veins. (05 Mar 2000) |
| lamina alaris | The dorsal division of the lateral walls of the neural tube in the embryo; it gives rise to neurons relaying afferent impulses to higher centres; in the adult such neurons compose the sensory nuclei of the spinal cord and brainstem. Synonym: lamina alaris, alar plate of neural tube, dorsolateral plate of neural tube, lamina dorsalis, wing plate. (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 arcus vertebrae | The flattened posterior portion of the vertebral arch extending between the pedicles and the midline, forming the dorsal wall of the vertebral foramen, and from the midline junction of which the spinous process extends. Synonym: lamina arcus vertebrae, neurapophysis. (05 Mar 2000) |
| lamina basalis | The ventral division of the lateral walls of the neural tube in the embryo; it contains neuroblasts giving rise to somatic and visceral motor neurons. Synonym: lamina basalis, basal plate of neural tube, lamina ventralis, ventral plate of neural tube. (05 Mar 2000) |
| lamina basalis choroideae | The transparent, nearly structureless inner layer of the choroid in contact with the pigmented layer of the retina. Synonym: basal lamina of choroid, basal layer of choroid, Bruch's membrane, Henle's membrane, lamina vitrea, vitreous lamella, vitreous membrane. (05 Mar 2000) |
| lamina basalis corporis ciliaris | The inner layer of the ciliary body, continuous with the basal layer of the choroid and supporting the pigment epithelium of the ciliary retina. Synonym: lamina basalis corporis ciliaris, basal layer of ciliary body. (05 Mar 2000) |
| lamina basilaris cochleae | A thin layer of tissue covered with mesothelial cells that separates the cochlea from the scala tympani in the ear. (18 Nov 1997) |
| lamina cartilaginis cricoideae | A quadrate plate forming the posterior part of the cricoid cartilage. It resembles the shield of a signet ring, the arch of the cricoid representing the remainder of the ring. Synonym: lamina cartilaginis cricoideae. (05 Mar 2000) |
