What does Thoracodorsal nerve innervate?
What does Thoracodorsal nerve innervate?
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 happens if Thoracodorsal nerve is damaged?
An intact thoracodorsal nerve may also cause atrophy of the muscle, which can lead to shoulder and arm weakness that hampers numerous common movements, including standing up from a chair.
Is the Thoracodorsal nerve a peripheral nerve?
The thoracodorsal nerve is a nerve present in humans and other animals, also known as the middle subscapular nerve or the long subscapular nerve. It supplies the latissimus dorsi muscle….

What nerve Innervates subscapularis?
The subscapularis is innervated by both the upper subscapular nerve (USN) and lower subscapular nerve (LSN). Both the USN and LSN arise from the posterior cord of the brachial plexus.
What nerve runs with the thoracodorsal artery?
The thoracodorsal artery gives off one to three branches of about 1 mm diameter to the serratus anterior which penetrate the muscle in its midportion along the course of the long thoracic nerve.
What does the thoracodorsal artery supply?
Branches and supply Along its course, the thoracodorsal artery gives rise to several cutaneous and muscular branches that supply the adjacent latissimus dorsi, serratus anterior, subscapularis and teres major muscles as well as the skin in the axillary region.
What Innervates rhomboid major?
The rhomboids are important in upper limb movement and stability of both the shoulder girdle and scapula. Both rhomboids receive innervation from the dorsal scapular nerve and supplied by the dorsal scapular artery.
What muscle is innervated by the trochlear nerve?
The trochlear nerve supplies one of the muscles that moves the eye-the superior oblique muscle. Contraction of this muscle turns the eye downwards and outwards. the fourth cranial nerve on vertebrates, which innervates the superior oblique muscles of the eye.
What do the nerves of the thoracic spine control?
Nerves of this area also innervate and help control the diaphragm, deltoids, biceps, triceps, hands and wrist extenders. The thoracic region of the spinal cord is protected by 12 vertebrae and helps control the muscles of the chest that are involved in breathing and coughing. This is the middle region of the spinal cord.
What cranial nerve innervates with the stomach?
The vagus nerve is the tenth cranial nerve (CN X) and is responsible for parasymapthetic nerve supply to the stomach. It enters the abdomen through the esophageal hiatus in the diaphragm.
Which nerve innervates the supinator?
Supinator muscle Innervation/Nerve supply. The posterior interosseous nerve, situated in the forearm as a continuation of the deep branch of the radial nerve, innervates the muscle. In 70% of cases, the deep branches of the radial nerve traverse the belly of the muscle.
