ba·sal lam·i·na of cho·roid [TA] the transparent, nearly structureless inner layer of the choroid in contact with the pigmented layer of the retina. Synonym(s): lamina basalis choroideae [TA]lam·i·na ba·sa·lis cho·roi·de·ae (lam'i-nă bā-sā'lis kō-roy'dē-ē) [TA] The transparent, nearly structureless inner layer of the choroid in contact with the pigmented layer of the retina.
Synonym(s): basal layer of choroid, Bruch membrane, vitreous lamella, vitreous membrane (3) . lamina (lam'i-na) plural.laminae [L. lamina, thin plate] 1. A thin flat layer or membrane.2. The flattened part of either side of the arch of a vertebra.alar laminaThe alar plate of the neural tube, which later develops into sensory nuclei and tracts of the central nervous system.alar lamina of neural tubeAlar plate.anterior elastic lamina See: Bowman, Sir Williambasal laminaAn 80 nm thick extracellular layer of fibrils and proteoglycans along the basal surface of a variety of cells, including many epithelia, capillary endothelia, Schwann cells, and muscle cells. Basal laminae anchor cells, organize cell-cell interactions, and act as semipermeable membranes.lamina basalis choroideaeBruch's membrane. See: Bruch, Karllamina basilaris ductus cochlearisThe membranous portion of the spiral lamina of the cochlea of the inner ear.Bowman lamina See: Bowman, Sir Williamlamina cartilaginis cricoideaeThe posterior portion of the cricoid cartilage.lamina choriocapillarisThe middle layer of the choroid, containing a dense mesh of capillaries. Synonym: choriocapillary layer; Ruysch's membranelamina cribrosaThe cribriform plate of the ethmoid bone.lamina cribrosa scleraeThe portion of the sclera forming a sievelike plate through which pass fibers of the optic nerve to the retina.dental laminaA U-shaped internal growth of the oral epithelium in the embryonic maxillary and mandibular regions that forms into enamel organs which produce the teeth. See: enamel organlamina duraIn radiography, the compact bone (alveolar bone proper) that surrounds the roots of teeth. In a state of health, it appears on a radiograph as a dense radiopaque line. epithelial laminaThe epithelial layer covering the choroid layer of the eye.lamina fusca scleraeThe layer of thin pigmented connective tissue on the inner surface of the sclera of the eye.internal medullary laminaThe layer of white matter that divides the gray matter of the thalamus into three parts: anterior, medial, and lateral.interpubic fibrocartilaginous laminaPart of the articulation of the pubic bones, connecting the opposing surfaces of these bones.labial laminaA thickened band of epithelium that grows from the ectodermal covering of the embryonic jaw. The ectodermal plate splits and separates the lip from the gum. lamina multiformisThe polymorphic layer of the isocortex of the cerebral cortex.lamina papyraceaA thin, smooth plate of bone on the lateral surface of the ethmoid bone; it forms part of the orbital plate.perpendicular laminaA thin sheet of bone forming the perpendicular plate of the ethmoid bone. It supports the upper portion of the nasal septum. lamina propria mucosaeThe thin layer of areolar connective tissue, blood vessels, and nerves that lies immediately beneath the surface epithelium of mucous membranes.pterygoid laminaEither of two plates, the internal and external, that make up the pterygoid process of the sphenoid bone. They are areas of attachment for the muscles of mastication. lamina quadrigeminaThe two pairs of bulges on the top of the midbrain section of the brainstem. The rostral pair are the superior colliculi, which are concerned with visual stimuli. The caudal pair are the inferior colliculi, which are concerned with auditory stimuli. Synonymous with tectum. rostral laminaA continuation of the rostrum of the corpus callosum and the terminal lamina of the third ventricle of the brain.spiral laminaA thin, bony plate projecting from the modiolus into the cochlear canal, dividing it into two portions, the upper scala vestibuli and lower scala tympani. Synonym: lamina spiralislamina spiralisSpiral lamina.suprachoroid laminaThe superficial layer of the choroid consisting of thin transparent layers, the outermost adhering to the sclera. See: lamina suprachoroidea Synonym: suprachoroidealamina suprachoroideaThe outermost layer of the choroid. lamina terminalisThe frontmost (rostral) wall of the neural tube. In the developed brain, the lamina terminalis remains as the thin rostral wall of the third ventricle, stretching from the bases of the major cerebral commissures (the anterior commissure, the commissure of the fornix, and the rostrum of the corpus callosum) to the dorsal surface of the optic chiasm. lamina of vertebral archOne of the laminae extending from the pedicles of the vertebral arches and fusing together to form the dorsal portion of the arch. The spinous process extends from the center of these laminae. vestibular laminaLabial lamina.lamina vitreaBruch membrane.lamina zonalisThe outer or plexiform layer of the isocortex of the brain.Bruch, Carl W.L., German anatomist, 1819-1884. Bruch glands - lymph nodes in the palpebral conjunctiva. Synonym(s): trachoma glandsBruch membrane - the transparent, nearly structureless inner layer of the choroid in contact with the pigmented layer of the retina. Synonym(s): lamina basalis choroideae
