38485. Anatomical terms of muscle. [edit on Wikidata] The brachioradialis is a muscle of the forearm that flexes the forearm at the elbow. [1][2] It is also capable of both pronation and supination, depending on the position of the forearm. [2] It is attached to the distal styloid process of the radius by way of the brachioradialis tendon, and ...
Common geometric terms of location are: Radial – along a direction pointing along a radius from the center of an object, or perpendicular to a curved path. Circumferential (or azimuthal) – following around a curve or circumference of an object. For instance: the pattern of cells in Taylor–Couette flow varies along the azimuth of the ...
23489. Anatomical terms of bone. [edit on Wikidata] Beneath the neck of the radius, on the medial side, is an eminence, the radial tuberosity; its surface is divided into: a posterior, rough portion, for the insertion of the tendon of the biceps brachii. [1][2][3][4] an anterior, smooth portion, on which a bursa is interposed between the tendon ...
Rotational symmetry of order n, also called n-fold rotational symmetry, or discrete rotational symmetry of the nth order, with respect to a particular point (in 2D) or axis (in 3D) means that rotation by an angle of (180°, 120°, 90°, 72°, 60°, 51 3⁄7 °, etc.) does not change the object. A "1-fold" symmetry is no symmetry (all ...
Lister's tubercle is found on the dorsal distal radius. [1] It varies in size and shape significantly. [2][3] It can range from around 2 to 6 mm in height (averaging 3 mm), and around 6 to 26 mm in length (averaging 13 mm). [2][3]
The radius is a long bone, prism -shaped and slightly curved longitudinally. The radius is part of two joints: the elbow and the wrist. At the elbow, it joins with the capitulum of the humerus, and in a separate region, with the ulna at the radial notch. At the wrist, the radius forms a joint with the ulna bone.
Clinical significance. The radial artery lies superficially in front of the distal end of the radius, between the tendons of the brachioradialis and flexor carpi radialis; it is here that clinician takes the radial pulse. (where it is commonly used to assess the heart rate and cardiac rhythm).
Symmetry (geometry) A drawing of a butterfly with bilateral symmetry, with left and right sides as mirror images of each other. In geometry, an object has symmetry if there is an operation or transformation (such as translation, scaling, rotation or reflection) that maps the figure/object onto itself (i.e., the object has an invariance under ...
