| heart atrium | The upper right and left chambers of the heart. (12 Dec 1998) |
|---|---|
| nasal atrium | The anterior expanded portion of the middle meatus of the nose, just above the vestibule. Synonym: atrium meatus medii, atrium. (05 Mar 2000) |
| oblique vein of left atrium | A small vein on the posterior wall of the left atrium which merges with the great cardiac vein to form the coronary sinus; it is developed from the left common cardinal vein, and occasionally persists as a left superior vena cava. Synonym: vena obliqua atrii sinistri, Marshall's oblique vein. (05 Mar 2000) |
| left atrium | <anatomy> The thin-walled chamber of the heart which pumps blood into the left ventricle for ejection into the systemic circulation. (27 Sep 1997) |
| 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) |
| RNA 3'-terminal phosphate cyclase | <enzyme> ATP dependent; forms 2',3' terminal cyclic phosphate on RNA which is then the substrate for RNA ligase of hela cells Registry number: EC 6.5.- Synonym: RNA tph cyclase (26 Jun 1999) |
| c-Jun amino-terminal kinase | <enzyme> A stress-activated protein kinase; 46-kD kinase that phosphorylates ser(63) and ser(73) of c-jun; similar to yeast hog1 kinase; amino acid sequence given in second source; genbank l23118 Registry number: EC 2.7.10.- Synonym: jn kinase, jnk1 protein kinase, jnk-46, jnk1 protein, jun-nh2-terminal kinase, stress-activated protein kinase 1, sap kinase-1, sapk1, p46 sap kinase, c-jun kinase-1 (26 Jun 1999) |
