The shoulder girdle [5] or pectoral girdle, [6] composed of the clavicle and the scapula, connects the upper limb to the axial skeleton through the sternoclavicular joint (the only joint in the upper limb that directly articulates with the trunk), a ball and socket joint supported by the subclavius muscle which acts as a dynamic ligament. While ...
The distal part of the upper limb between the elbow and the radiocarpal joint (wrist joint) is known as the forearm or "lower" arm, and the extremity beyond the wrist is the hand. By anatomical definitions, the bones , ligaments and skeletal muscles of the shoulder girdle , as well as the axilla between them, are considered parts of the upper ...
Anconeus is innervated by a branch of the radial nerve (cervical roots 7 and 8) [7] from the posterior cord of the brachial plexus called the nerve to the anconeus. The somatomotor portion of radial nerve innervating anconeus bifurcates from the main branch in the radial groove of the humerus.
The cubital fossa, antecubital fossa, chelidon, or inside of elbow is the area on the anterior side of the upper part between the arm and forearm of a human or other hominid animals. It lies anteriorly to the elbow (antecubital) (Latin cubitus ) when in standard anatomical position .
The palmar branch of the ulnar nerve arises about five cm proximal to the wrist from where the ulnar nerve splits into palmar and dorsal branches. It supplies sensory innervation to a small area in the palmar surface of the wrist.

The brachialis (brachialis anticus) is a muscle in the upper arm that flexes the elbow. It lies beneath the biceps brachii, and makes up part of the floor of the region known as the cubital fossa (elbow pit). It originates from the anterior aspect of the distal humerus; [1] it inserts onto the tuberosity of the ulna.
The brachial artery is the major blood vessel of the (upper) arm. It is the continuation of the axillary artery beyond the lower margin of teres major muscle. It continues down the ventral surface of the arm until it reaches the cubital fossa at the elbow. It then divides into the radial and ulnar arteries which run down the forearm.
