    the digital/phalangeal region encompassing the toes. The great toe is referred to as the hallux. The regions of the upper limbs, from superior to inferior, are the axillary region encompassing the armpit, the brachial region encompassing the upper arm, the antecubital region encompassing the front of the elbow,

  3. Brachial plexus - Wikipedia

    en.wikipedia.org/wiki/Brachial_plexus

    The brachial plexus is a network of nerves (nerve plexus) formed by the anterior rami of the lower four cervical nerves and first thoracic nerve (C5, C6, C7, C8, and T1).This plexus extends from the spinal cord, through the cervicoaxillary canal in the neck, over the first rib, and into the armpit, it supplies afferent and efferent nerve fibers to the chest, shoulder, arm, forearm, and hand.

    The lateral intermuscular septum extends from the lower part of the crest of the greater tubercle of the humerus, along the lateral supracondylar ridge, to the lateral epicondyle; it is blended with the tendon of the deltoid muscle, gives attachment to the triceps brachii behind, and to the brachialis, brachioradialis, and extensor carpi radialis longus muscles in front.

    en.wikipedia.org/wiki/Deep_artery_of_arm

    It follows closely the radial nerve, running at first backward between the long and medial [1] heads of the triceps brachii, then along the groove for the radial nerve (the radial sulcus), where it is covered by the lateral head of the triceps brachii, to the lateral side of the arm; there it pierces the lateral intermuscular septum, and, descending between the brachioradialis and the ...

  6. Brachial artery - Wikipedia

    en.wikipedia.org/wiki/Brachial_artery

    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.

  7. Brachialis muscle - Wikipedia

    en.wikipedia.org/wiki/Brachialis_muscle

    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).

  8. Arm - Wikipedia

    en.wikipedia.org/wiki/Human_arm

    The main artery in the arm is the brachial artery. This artery is a big continuation of the axillary artery. The point at which the axillary becomes the brachial is distal to the lower border of teres major. The brachial artery gives off an unimportant branch, the deep artery of arm. This branching occurs just below the lower border of teres major.

  9. Upper trunk - Wikipedia

    en.wikipedia.org/wiki/Upper_trunk

    The upper (superior) trunk is part of the brachial plexus. It is formed by joining of the ventral rami of the fifth (C5) and sixth (C6) cervical nerves. The upper trunk divides into an anterior and posterior division. The branches of the upper trunk from proximal to distal are: subclavian nerve (C5-C6) suprascapular nerve (C5-C6)
