tensity (tensiti)

[ A tensive pain from distension of the parts. Floyer , Preternatural State of Animal Humours. ten some (ten's um), a. Same as tend some. tenson (ten's on), n. [Also tenzon; While, out of dream, his day's work went To tune a crazy tenzon or sirvent. Browning, Sordello, ii. tensor (ten's or), n. and a. [NL., 6234 it tense, or put it upon the stretch: differing from an extensor in not changing the relative position or direction of the axis of the part: opposed to laxator.-2. In math., the modulus of a quaternion; the ratio in which it stretches the length of a vector. If the quaternion is put into the form xi + yj + zk + w, the tensor is √(x + y2 + z2 + w2). If the quaternion is expre ed as a matrix, the tensor is the square root of the determinant of the matrix. Abbreviated T. - Right tensor. See right. Tensor fascice late. Same as tensor vagine femoris. - Tensor lam inæ posterior is vag inæ recti abdominis, small anomalous muscular slips arising near the internal inguinal opening, and inserted into the transversal is fascia beneath the rectus abdominis. - Tensor palati. Same as circumflex us palati. See palatum. Tensor parapatagii, in ornith., the tightener of the para patagium, a pro patagial slip of the cucullar muscle which joins the pro patagial is long us; the dermotensor patagii. Tensor patagii, tensor plicæ alaris, a muscle of birds which stretches the fold of skin on the front border of the wing, in the reëntrance between the upper arm and the forearm: several modifications of such a muscle are described, and made use of to some extent in cla ifying birds. - Tensor propatagii brevis or long us. Same as pro patagial is brevis or long us. See prop a tagialis. Tensor tarsi. See tarsus. - Tensor trochleæ, the tightener of the pulley of the trochlear or superior oblique muscle of the eyeball, a small muscle occasionally found in man. - Tensor tympani, a muscle supposed to increase the tension of the membrani tympani by acting upon the malleus: it arises from the petrous section of the temporal bone, and adjacent parts, pa es through a bony canal parallel with the Eustachian tube, enters the tympanum, and is attached to the handle of the malleus. Also called malled i us. - Tensor vag inæ femoris, a muscle which acts upon the sheath of the thigh, in man arising from the anterior superior spine of the ilium, and inserted into the deep femoral fascia. It presents many modifications in other animals, being wanting in some, or connected with the panniculus carnosus, or external abdominal muscle, or blended with gluteal muscles. It belongs to the latter group, and not to the muscles of the front of the thigh, with which it is usually a ociated in human anatomy. Also called tensor fasciæ latæ, and vagi niglutæus. See cut under muscle1. II. a. In an at . , noting certain muscles whose function is to render fasciæ or other structures tense. tensor-twist (ten's or-twist), n. In Clifford's biquaternions, a twist multiplied by a tensor. ten-strike (ten's trik), n. In American bowling , a stroke which knocks down all the ten pins; hence, figuratively, a stroke or act of any kind which is entirely succe ful or decisive. tensuret (ten'sūr), n. [ tensura , a stretching, straining, tendere , pp. tens us , stretch, strain: see tend1 , tense2 .] A stretching or straining; tension. This motion upon the pre ure, and the reciprocal thereof, which is motion upon tensure, we use to call motion of liberty, which is when any body, being forced to a preternatural extent, restoreth itself to be natural.
