| vesicle hernia | Protrusion of a segment of the bladder through the abdominal wall or into the inguinal canal and into the scrotum. (05 Mar 2000) |
|---|---|
| cerebral vesicle | Each of the three divisions of the early embryonic brain (prosencephalon, mesencephalon, and rhombencephalon). Synonym: encephalic vesicle, primary brain vesicle. (05 Mar 2000) |
| cervical vesicle | An abnormally persisting vestige of the cervical sinus or its associated branchial grooves. (05 Mar 2000) |
| membrane vesicle | <cell biology> Closed unilamellar shells formed from membranes either in physiological transport processes or else when membranes are mechanically disrupted. They form spontaneously when membrane is broken because the free ends of a lipid bilayer are highly unstable. (18 Nov 1997) |
| phagocytic vesicle | <cell biology> Membrane bounded vesicle enclosing a particle internalised by a phagocyte. The primary phagocytic vesicle phagosome) will subsequently fuse with lysosomes to form a secondary phagosome in which digestion will occur. Origin: L. Phagedaena, Gr Phago, To eat. (18 Nov 1997) |
| midbrain vesicle | <anatomy> The middle segment of the brain; the midbrain. Sometimes abbreviated to mesen. See Brain. Origin: NL. See Meso- and Encephalon. Source: Websters Dictionary (01 Mar 1998) |
| 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) |
| mucosa of seminal vesicle | The mucous membrane of the seminal vesicle. Synonym: tunica mucosa vesiculae seminalis. (05 Mar 2000) |
| 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) |
| seminal vesicle | <anatomy> The paired glands at the base of the bladder that produce seminal fluid and fructose. (09 Oct 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) |
