In four-legged animals, the radius is the main load-bearing bone of the lower forelimb. Its structure is similar in most terrestrial tetrapods , but it may be fused with the ulna in some mammals (such as horses ) and reduced or modified in animals with flippers or vestigial forelimbs.
The medial crural cutaneous branches of saphenous nerve provide cutaneous innervation to the medial leg. This page was last edited on 18 December 2024, at 17:25 (UTC) ...
Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve.
The diameter (at the medial sural cutaneous nerve origin) is found to be 2.74mm ± 0.93 (2.62–2.86) in 207 samples. Two new variations (as of 2021) of the sural nerve complex were observed where the MSCN is observed to travel to the lateral ankle and provides the branches for the lateral calcaneal nerves of the lateral ankle.
A forelimb or front limb is one of the paired articulated appendages attached on the cranial end of a terrestrial tetrapod vertebrate's torso. With reference to quadrupeds, the term foreleg or front leg is often used instead. In bipedal animals with an upright posture (e.g. humans and some other primates), the term upper limb is often used.
The volar branch (ramus volaris; anterior branch), the larger, passes usually in front of, but occasionally behind, the vena mediana cubiti (median basilic vein).. It then descends on the front of the ulnar side of the forearm, distributing filaments to the skin as far as the wrist, and communicating with the palmar cutaneous branch of the ulnar nerve.

Limbs are attached to the torso via girdles, either the pectoral girdle for the forelimbs, or the pelvic girdle for the hindlimbs.In terrestrial tetrapods, the pectoral girdles are more mobile, floating over the rib cage connected only via the clavicles (to the sternum) and numerous muscles; while the pelvic girdles are typically fused together anteriorly via a fibrocartilaginous joint and ...
