| intermediate part of vestibular bulb | A narrow median band that connects the two masses of erectile tissue (the bulbus vestibuli) on either side of the vaginal orifice. Synonym: pars intermedia commissura bulborum, commissura bulborum, intermediate part of vestibular bulb, pars intermedia bulborum. (05 Mar 2000) |

| olfactory bulb | Ovoid body resting on the cribriform plate of the ethmoid bone where the olfactory nerve terminates. The olfactory bulb contains several types of nerve cells including the mitral cells, on whose dendrites the olfactory nerve synapses, forming the olfactory glomeruli. The accessory olfactory bulb, which receives the projection from the vomeronasal organ via the vomeronasal nerve, is also included here. (12 Dec 1998) |
| onion bulb neuropathy | Designation for any of several demyelinating polyneuropathies in which the nerves are enlarged, due to onion bulb formation-whorls of overlapping Schwann cell processes encircling bare medullated axons, e.g., progressive hypertrophic polyneuropathy. See: hypertrophic interstitial neuropathy. (05 Mar 2000) |
| taste bulb | One of a number of flask-shaped cell nests located in the epithelium of vallate, fungiform, and foliate papillae of the tongue and also in the soft palate, epiglottis, and posterior wall of the pharynx; it consists of sustentacular, gustatory, and basal cells between which the intragemmal sensory nerve fibres terminate. Synonym: caliculus gustatorius, gustatory bud, Schwalbe's corpuscle, taste bulb, taste corpuscle. (05 Mar 2000) |
| end bulb | One of the oval or rounded bodies in which the sensory nerve fibres terminate in mucous membrane. (05 Mar 2000) |
| jugular bulb | <anatomy, vein> One of two dilated parts of the internal jugular vein: the superior bulb (Heister's diverticulum) is a dilation at the beginning of the internal jugular vein in the jugular fossa of the temporal bone; the inferior bulb is a dilat ed portion of the vein just before it reaches the brachiocephalic vein. Synonym: jugular bulb, bulbus venae jugularis. (05 Mar 2000) |
| absolute terminal innervation ratio | The number of motor endplates divided by the number of terminal axons related to them. (05 Mar 2000) |
| amino-terminal | <biochemistry> The end of a protein or polypeptide chain with the unattached amino group or the aminoacyl residue containing it. Each amino acid in the chain has an amino group on one side, which is attached to the carboxyl group (COOH group) of the previous amino acid, and a carboxyl group on the other side (which is attached to the amino group of the next amino acid). The other end of the polypeptide chain is called the carboxyl terminal. Synonym: NH2-terminal. (14 Aug 2000) |
| amino-terminal residue | <biochemistry> The only amino acid residue in a polypeptide chain that has a free alpha-amino group, it defines the amino terminus of the polypeptide. (09 Oct 1997) |
| axonal terminal boutons | The somewhat enlarged, often club-shaped endings by which axons make synaptic contacts with other nerve cells or with effector cells (muscle or gland cells). As isolated, by homogenizing brain or spinal cord, they contain acetylcholine and the related enzymes. Terminals contain neurotransmitters of various kinds, sometimes more than one. These can be demonstrated by chemical analysis and immunocytochemical methods. See: synapse. Synonym: axonal terminal boutons, end-feet, neuropodia, pieds terminaux, synaptic boutons, synaptic endings, synaptic terminals, terminal boutons, bouton terminaux. (05 Mar 2000) |
| carboxyl terminal | The end of a polypeptide chain with the unattached carboxyl group (a -COOH group). Each amino acid in the middle of the chain has an amino group (a -NH2 group) on one side (which is attached to the carboxyl group of the previous amino acid) and a carboxyl group on the other side (which is attached to the amino group of the next amino acid). The other end of the polypeptide chain is called the amino terminal. (09 Oct 1997) |
| carboxyl-terminal residue | This amino acid residue defines the carboxylterminus of the polypeptide, its the only residue with a free alpha-carboxyl group. (09 Oct 1997) |
| carboxy terminal | The end of a peptide or protein having a free carboxyl (-COOH) group. (05 Mar 2000) |
| carboxy-terminal domain kinase | <enzyme> Protein kinase that phosphorylates the c-terminal repeat domain of the largest subunit of RNA polymerase II at serine residues Registry number: EC 2.7.1.- Synonym: ctd kinase, hs-ctd kinase, tfiih-associated ctd kinase (26 Jun 1999) |
| central terminal electrode | In electrocardiography, an electrode in which connections from the three limbs (right arm, left arm, and left leg) are joined and led to the electrocardiograph to form the indifferent electrode, theoretically at zero potential for the system. (05 Mar 2000) |
