| membrana limitans gliae | A dense, resilient membrane forming the true capsule of the brain and spinal cord, composed of the processes of astrocytes (macroglia cells) and covered throughout by the pia mater, which firmly adheres to it; the two membranes are collectively called the pial-glial membrane. Synonym: membrana limitans gliae. (05 Mar 2000) |
| sulcus limitans | The medial longitudinal groove on the inner surface of the neural tube separating the alar and basal plates. Synonym: sulcus limitans. (05 Mar 2000) |
| sulcus limitans fossae rhomboideae | A lateral groove running the whole length of the floor of the rhomboid fossa on either side of the midline, representing the remains of the sulcus demarcating the alar (dorsal) from the basal (ventral) plate of the embryonic rhombencephalon. Synonym: sulcus limitans fossae rhomboideae. (05 Mar 2000) |
| lamina limitans anterior corneae | A transparent homogeneous acellular layer, 6 to 9 um thick, lying between the basal lamina of the outer layer of stratified epithelium and the substantia propria of the cornea; considered to be a basement membrane. Synonym: lamina limitans anterior corneae, anterior elastic layer, Bowman's membrane, lamina elastica anterior, limiting layers of cornea. (05 Mar 2000) |
| lamina limitans posterior corneae | A transparent homogeneous acellular layer between the substantia propria and the endothelial layer of the cornea; considered to be a highly developed basement membrane. Synonym: lamina limitans posterior corneae, membrana vitrea, Descemet's membrane, Duddell's membrane, entocornea, hyaloid membrane, lamina elastica posterior, limiting layers of cornea, membrana hyaloidea, posterior elastic layer, tunica vitrea, vitreous membrane.
