What does the medial cutaneous nerve supply?
The medial cutaneous nerve of the forearm, also known as the medial antebrachial cutaneous nerve, is a branch of the medial cord of the brachial plexus and supplies the anterior and medial aspects of the forearm as far distal as the wrist.
What does the medial antebrachial cutaneous nerve come from?
The medial cutaneous nerve of the forearm (medial antebrachial cutaneous nerve) branches from the medial cord of the brachial plexus. It contains axons from the ventral rami of the eighth cervical (C8) and first thoracic (T1) nerves.
What does the medial pectoral nerve innervate?
The medial pectoral nerve continues on to innervate pectoralis minor, actually piercing pectoralis minor to also supply the overlying pectoralis major. Also stemming from the medial cord are the medial cutaneous nerves of the arm and forearm.
What muscles does the median nerve innervate?
The median nerve innervates many muscles of the anterior forearm and hand, providing signals to and from the brain and spinal cord. The flexor digitorum superficialis and pronator quadratus are among the muscles of the anterior forearm that are solely innervated by the median nerve.
What nerve innervates the biceps?
The musculocutaneous nerve innervates the three muscles of the anterior compartment of the arm: the coracobrachialis, biceps brachii, and brachialis. It is also responsible for cutaneous innervation of the lateral forearm.
Where is the median Antebrachial vein located?
The median antebrachial vein is a superficial vein of the anterior forearm that drains the superficial structures of the forearm and wrist between the basilic and cephalic veins.
What does Thoracodorsal nerve supply?
The thoracodorsal nerve is a pure motor nerve that innervates the latissimus dorsi muscle. The primary blood supply of the latissimus dorsi muscle is the thoracodorsal artery. The dorsal divisions of T6 to T12 provide the sensory innervation of the skin of the latissimus dorsi muscle.
Where is the medial brachial cutaneous nerve?
The medial brachial cutaneous nerve (lesser internal cutaneous nerve; medial cutaneous nerve of arm) is distributed to the skin on the medial brachial side of the arm.
What muscles does median nerve supply?
The median nerve is the main nerve of the front of the forearm. It supplies the muscles of the front of the forearm and muscles of the thenar eminence, thus controlling the coarse movements of the hand….Forearm
- Pronator teres.
- Flexor carpi radialis.
- Palmaris longus.
Where is the medial antebrachial nerve?
The medial antebrachial cutaneous nerve (internal cutaneous nerve, medial cutaneous nerve of forearm) arises from the medial cord of the brachial plexus. It derives its fibers from the eighth cervical and first thoracic nerves, and at its commencement is placed medial to the axillary artery.
Where does the medial cutaneous nerve come from?
Anatomical terms of neuroanatomy. [edit on Wikidata] The medial antebrachial cutaneous nerve (internal cutaneous nerve, medial cutaneous nerve of forearm) arises from the medial cord of the brachial plexus. It derives its fibers from the eighth cervical and first thoracic nerves, and at its commencement is placed medial to the axillary artery.
Is the intercostobrachial nerve part of the medial cord?
Along with the medial cutaneous nerve of the arm (an intermediary branch of the medial cord), the intercostobrachial nerve provides cutaneous sensation to the upper half of the medial/posterior arm. It also innervates a portion of the anterior axilla (see Figures 1 and 2 ).
Which is the cutaneous branch of the musculocutaneous nerve?
The lateral antebrachial cutaneous nerve of the forearm (LAC) is the primary cutaneous branch of the musculocutaneous nerve. It provides cutaneous innervation to the lateral (radial) half of the volar forearm.
