What does thoracodorsal nerve innervate?
the latissimus dorsi muscle
The thoracodorsal nerve is a pure motor nerve that innervates the latissimus dorsi muscle.
What happens when thoracodorsal nerve is injured?
Injury to the thoracodorsal nerve is one of the complications related to the axillary dissection. The thoracodorsal nerve innervates the latissimus dorsi muscle which facilitates in certain movements of the arm. Moreover, it can be used as a nerve graft in long thoracic nerve injury whether in trauma or surgery.
What nerve runs with thoracodorsal A?
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 does dorsal scapular nerve innervate?
The DSN is a motor nerve that innervates the levator scapulae, rhomboid major, and rhomboid minor muscles. These muscles work dynamically and collectively are considered periscapular stabilizing muscles.
What nerve Innervates the wrist extensors?
The radial nerve
The radial nerve and its branches provide motor innervation to the dorsal arm muscles (the triceps brachii and the anconeus) and the extrinsic extensors of the wrists and hands; it also provides cutaneous sensory innervation to most of the back of the hand, except for the back of the little finger and adjacent half of …
Where can the thoracodorsal bundle be identified?
The lateral thoracic vein was identified and traced bi-directionally. The anatomical location of the thoracodorsal nerve was studied in relation to the lateral border of pectoralis minor and from a point along the lateral thoracic vein, 2 cm inferior to its confluence with the axillary vein.
What is thoracodorsal pedicle?
The thoracodorsal nerve, thoracodorsal artery and thoracodorsal vein are collectively known as the thoracodorsal pedicle (TDP). The TDP descends on the posterior wall of the axilla. The TDN rarely runs 2 to 3 cm medial to the thoracodorsal artery and vein [5].
What happens if dorsal scapular nerve is injured?
Injury to this nerve results in atrophy and weakness of the rhomboideus major and minor and can be observed as absence of bulk medial to the scapula and between that structure and the thoracic spinal column.
What nerve Innervates the finger extensors?
The radial nerve innervates the finger extensors and the thumb abductor; that is, the muscles that extend at the wrist and metacarpophalangeal joints (knuckles) and abduct and extend the thumb.
What nerve Innervates the thumb and index finger?
The median nerve
The median nerve is also responsible for touch, pain and temperature sensations to the: Bottom (palm) side of the thumb, index and middle fingers, and part of the ring finger.
What Innervates rhomboid major?
the dorsal scapular nerve
Both rhomboids receive innervation from the dorsal scapular nerve and supplied by the dorsal scapular artery.
What does thoracodorsal artery supply?
The thoracodorsal artery supplies predominantly the latissimus dorsi muscle but also gives branches to the serratus anterior muscle, the axillary skin, the subscapular and teres major muscles.
