| coated vesicle | <cell biology> Vesicle formed as an invagination of the plasma membrane (a coated pit) and that is surrounded by a basket of clathrin. Associated with receptor mediated pinocytosis and receptor recycling. (18 Nov 1997) |
|---|---|
| pinocytotic vesicle | Fluid filled endocytotic vesicle, usually less than 150 nm diameter. Micropinocylotic vesicles are around 70 nm diameter. (18 Nov 1997) |
| cortical vesicle | A vesicle, or membrane-bound bubble, in an animal egg cell that releases proteases and other enzymes immediately after fertilization, chiefly to change the egg's surface cell membrane so that no more sperm cells can enter. (09 Oct 1997) |
| primary brain vesicle | Each of the three divisions of the early embryonic brain (prosencephalon, mesencephalon, and rhombencephalon). Synonym: encephalic vesicle, primary brain vesicle. (05 Mar 2000) |
| hindbrain vesicle | That part of the brainstem constituting the medulla oblongata (myelencephalon) and pons (metencephalon). (12 Dec 1998) |
| secretory vesicle | <cell biology> Membrane bounded vesicle derived from the Golgi apparatus and containing material that is to be released from the cell. The contents may be densely packed, often in an inactive precursor form (zymogen). (18 Nov 1997) |
| synaptic vesicle | <cell biology> Intracellular vesicles found in the presynaptic terminals of chemical synapses, which contain neurotransmitter. During activity the vescles release their contents at the synapse and the neurotransmitter stimulate receptors on other cells. (10 Jan 1998) |
| inside out vesicle | Mechanical disruption of cell membranes gives rise to small closed vesicles surrounded by a bilayer membrane. These may be right side out (ROV) or IOV if the topography is inverted. (18 Nov 1997) |
| ocular vesicle | In the embryo, one of the paired evaginations from the ventrolateral walls of the forebrain from which the sensory and pigment layers of the retina develop. Synonym: vesicula ophthalmica, ocular vesicle, optic vesicle. (05 Mar 2000) |
| ophthalmic vesicle | In the embryo, one of the paired evaginations from the ventrolateral walls of the forebrain from which the sensory and pigment layers of the retina develop. Synonym: vesicula ophthalmica, ocular vesicle, optic vesicle. (05 Mar 2000) |
| optic vesicle | In the embryo, one of the paired evaginations from the ventrolateral walls of the forebrain from which the sensory and pigment layers of the retina develop. Synonym: vesicula ophthalmica, ocular vesicle, optic vesicle. (05 Mar 2000) |
| otic vesicle | One of the paired sacs of invaginated ectoderm that develop into the membranous labyrinth of the internal ear. Synonym: acoustic vesicle, otic vesicle. (05 Mar 2000) |
| telencephalic vesicle | Paired diverticula arising from the prosencephalon, from which the forebrain develops. (05 Mar 2000) |
| encephalic vesicle | Each of the three divisions of the early embryonic brain (prosencephalon, mesencephalon, and rhombencephalon). Synonym: encephalic vesicle, primary brain vesicle. (05 Mar 2000) |
| transcytotic vesicle | <cell biology> Membrane bounded vesicle that shuttles fluid from one side of the endothelium to the other. There is some controversy as to whether or not they form pores. (17 Mar 1998) |
