====Muscles of the Elbow====
====Muscles of the Elbow====
==Extensors==
''Flexors'': Musculocutaneous n. from the brachial plexus
'''Triceps brachii''': Radial n. from the brachial plexus
Has three heads, the medial branch is the most developed. The long head is at the caudal margin of the scapula; The lateral, medial, and accessory heads are at the shaft of the humerus.
Insertion: olecranon, proteced by tricipital bursa against the bone and subcutaneous bursa against the skin.
'''Tensor fasciae antebrachii''': Radial n. from the brachial plexus.
Overlies the triceps extending from the scapula to the olecranon.
==Flexors==
'''Biceps brachii''': Musculocutaneous n. from the brachial plexus.
Origin: supraglenoid tubercle of the scapula.
Insertion: medial tuberosity of proximal radius and adjacent ulna. It runs through the intertubercular groove of the humerus.
'''Brachialis''': Musculocutaneous n. from the brachial plexus.
Origin: proximocaudal humerus.
Insertion: spirals to insert next to biceps.
