| Xq | long arm of chromosome X |
| whole-arm fusion | <genetics, molecular biology> A break in the shortest arms of two acrocentric chromosomes followed by the fusion of the long arms into a single chromosome. (13 Nov 1997) |
|---|---|
| control arm | The group of participants in a clinical trial who receive standard treatment or a placebo, against which those receiving the experimental treatment are compared. (09 Oct 1997) |
| posterior cutaneous nerve of arm | <anatomy, nerve> A branch of the radial nerve supplying the skin of the posterior surface of the arm. Synonym: nervus cutaneus brachii posterior, posterior cutaneous nerve of arm. (05 Mar 2000) |
| posterior region of arm | The back of arm. Synonym: facies brachialis posterior, regio brachialis posterior, posterior brachial region, posterior surface of arm. (05 Mar 2000) |
| posterior surface of arm | The back of arm. Synonym: facies brachialis posterior, regio brachialis posterior, posterior brachial region, posterior surface of arm. (05 Mar 2000) |
| stabilizing circumferential clasp arm | An arm that is relatively rigid and embraces the height of contour of the tooth. (05 Mar 2000) |
| deep fascia of arm | The deep fascia of the arm; it is continuous proximally with the pectoral fascia and the fascia covering the deltoid; distally it is continuous with the antebrachial fascia. Synonym: fascia brachii, deep fascia of arm. (05 Mar 2000) |
| dynein arm | A structure extending clockwise from one tubule of each of the 9 doublet microtubules toward the adjacent doublet seen in the axoneme of cilia or flagella (including human sperm tails); congenital absence of dynein, reflected structurally by absence of dynein arm's, can account for symptoms seen in Kartagener's syndrome and in immotile cilia syndromes. (05 Mar 2000) |
| q arm | <cell biology> The long arm of a chromosome. All human chromosomes have 2 arms: the short (p) arm and the long (q) arms. (12 Dec 1998) |
| triceps muscle of arm | <anatomy, muscle> Origin, long or scapular head: lateral border of scapula below glenoid fossa, lateral head: lateral and posterior surface of humerus below greater tubercle, medial head: posterior surface of humerus below radial groove; insertion, olecranon of ulna; action, extends elbow; nerve supply, radial. Synonym: musculus triceps brachii, triceps muscle of arm. (05 Mar 2000) |
| upper lateral cutaneous nerve of arm | <anatomy, nerve> The terminal branch of the axillary nerve supplying the skin over the lower portion of the deltoid and for a distance below its insertion. Synonym: nervus cutaneus brachii lateralis superior, upper lateral cutaneous nerve of arm. (05 Mar 2000) |
| lateral surface of arm | The lateral surface of the arm. Synonym: facies lateralis brachii. (05 Mar 2000) |
| lower lateral cutaneous nerve of arm | <anatomy, nerve> A branch of the radial nerve supplying the skin of the lower lateral aspect of the arm; it frequently is a branch of the posterior antebrachial nerve. Synonym: nervus cutaneus brachii lateralis inferior, lower lateral cutaneous nerve of arm. (05 Mar 2000) |
| HIV long-terminal repeat | Regulatory sequences important for viral replication that are located on each end of the HIV genome. The ltr includes the HIV enhancer, promoter, and other sequences. Specific regions in the ltr include the negative regulatory element (nre), nf-kappa b binding sites , sp1 binding sites, tata box, and trans-acting responsive element (tar). The binding of both cellular and viral proteins to these regions regulates HIV transcription. (12 Dec 1998) |
| segment long spacing | <biochemistry> Abnormal packing pattern of collagen molecules formed if ATP is added to acidic collagen solutions, in which lateral aggregates of molecules are produced. Each aggregate is 300 nm long and the molecules are all in register. If segment long spacing aggregates are overlapped with a quarter stagger, the 67 nm banding pattern of normal fibrils is reconstituted. Acronym: SLS (18 Nov 1997) |
