Flexion and extension are movements that affect the angle between two parts of the body. These terms come from the Latin words with the same meaning. [a] Flexion is a bending movement that decreases the angle between a segment and its proximal segment. [9] For example, bending the elbow, or clenching a hand into a fist, are examples of flexion ...
Standard anatomical terms of location are used to describe unambiguously the anatomy of animals, including humans. The terms, typically derived from Latin or Greek roots, describe something in its standard anatomical position. This position provides a definition of what is at the front ("anterior"), behind ("posterior") and so on.
In anatomy, flexion (from the Latin verb flectere, to bend) [1] is a joint movement that decreases the angle between the bones that converge at the joint. For example, one's elbow joint flexes when one brings their hand closer to the shoulder. Flexion is typically instigated by muscle contraction of a flexor.
When the foot is plantar flexed, the ankle joint also allows some movements of side to side gliding, rotation, adduction, and abduction. [12] The bony arch formed by the tibial plafond and the two malleoli is referred to as the ankle "mortise" (or talar mortise). The mortise is a rectangular socket. [1]
22538. Anatomical terms of muscle. [edit on Wikidata] In human anatomy, the fibularis tertius (also known as the peroneus tertius) is a muscle in the anterior compartment of the leg. It acts to tilt the sole of the foot away from the midline of the body (eversion) and to pull the foot upward toward the body (dorsiflexion).
The muscle group is normally composed of three muscles: fibularis longus, fibularis brevis, and fibularis tertius. [1] The fibularis longus and fibularis brevis are located in the lateral compartment of the leg and are supplied by the fibular artery and the superficial fibular nerve. The fibularis tertius is located in the anterior compartment ...
Anatomical terminology. [ edit on Wikidata] The arches of the foot, formed by the tarsal and metatarsal bones, strengthened by ligaments and tendons, allow the foot to support the weight of the body in the erect posture with the least weight. They are categorized as longitudinal and transverse arches.
head of the radius. capitulum of the humerus. Is a ball-and-socket joint. Superior radioulnar joint. head of the radius. radial notch of the ulna. In any position of flexion or extension, the radius, carrying the hand with it, can be rotated in it. This movement includes pronation and supination.
