What does the subclavian nerve do?
What does the subclavian nerve do?
The nerve to subclavius (or subclavian nerve) innervates the muscle. This arises from the junction of the fifth and sixth cervical nerves, from the superior/upper trunk of the brachial plexus.
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.
What is in the supraclavicular triangle?
Supraclavicular triangle This triangle is the anterior division of the posterior cervical triangle. The anterior and inferior borders are the same as those of the posterior cervical triangle, but the superior border is the inferior belly of the omohyoid.
Where is the subclavian nerve located?
brachial plexus
The subclavian nerve, also known as the nerve to the subclavius, is small branch of the upper trunk of the brachial plexus. It contains axons from C5 and C6.
What nerve controls the shoulder?
Brachial plexus. The brachial plexus is a group of nerves that control the muscles of the shoulder, arm, forearm, and hand. These same nerves also provide sensations (feeling) of the whole upper limb.

What does the ulnar nerve innervate?
The ulnar nerve innervates the flexor muscles of the forearm including the flexor carpi ulnaris and flexor digitorum profundus. It also innervates the intrinsic muscles of the hand including the palmaris brevis, lumbricals, hypothenar and interossei muscles.
What is supraclavicular fossae?
The supraclavicular fossa (SCF) is defined as the concavity found just over the clavicle, and it is a subdivision of the posterior triangle of the neck. The sternocleidomastoid muscle and the omohyoid muscles constitute the anterior and superomedial borders, respectively.
What causes supraclavicular lymph nodes?
Glands above the collarbone (supraclavicular lymph nodes) may swell from an infection or tumor in the areas of the lungs, breasts, neck, or abdomen.
What muscles does the subclavian nerve innervate?
The suprascapular nerve comes off the upper trunk, from roots C5-C6, and innervates the supraspinatus and infraspinatus, which are contributors to the rotator cuff apparatus. Arising from anterior divisions of C5-C6, also from the upper trunk, the subclavian nerve innervates the subclavius muscle.
Can shoulder nerve damage be repaired?
There’s a misconception that nerves can’t regrow. They can. But the key to success in treating these injuries is speed. Surgical techniques to transfer nerves from other parts of the body to heal torn ones in the plexus have a window of only a few months to work, and recovery takes months to years.
¿Cuál es la función del músculo en el subclavio?
La función del músculo es, de una parte, la fijación de la clavícula en la articulación esternoclavicular, y, de otra parte, la protracción indirecta del hombro acercando la 1ª costilla a la clavícula. 4. Sobrecarga y formación de puntos gatillo en el subclavio
¿Qué son los nervios supraclaviculares?
Los nervios supraclaviculares son tres nervios cutáneos que emergen como tronco común del plexo cervical antes de ramificar para inervar la piel sobre el pecho y los hombros superiores. Los nervios supraclaviculares surgen de la rama ventral de los nervios espinales C3 y C4, aunque reciben considerablemente más fibras de C4.
¿Cómo se extiende el músculo en la clavícula?
Para decirlo simple, el músculo se extiende desde la clavícula hasta la 1ª costilla. El lado inferior exterior de la clavícula. El músculo es inervado por el nervio subclavio C5 – C6. 3. Función
¿Cuál es el patrón de ramificación de los nervios supraclaviculares?
El patrón de ramificación de los nervios supraclaviculares es altamente variable con hasta la mitad de la población que posee solamente ramas intermedias y laterales (es decir ninguna rama intermedia). Los nervios supraclaviculares pueden dañarse fácilmente durante la aproximación quirúrgica al eje clavicular.
