The long thoracic nerve descends through the cervicoaxillary canal. The C5 and C6 components of the long thoracic nerve roots primarily lie between the scalenus medius and the scalenus posterior muscles and sometimes they pass through the scalenus medius muscle [ 10 ]. The pinched nerve can occur at different areas along the thoracic spine.

Originates from roots C5, C6, C7, C8. The parenthesis around (8) means the nerve root at C8 may contribute to the innervation of this muscle, but the primary nerve roots are C 5,6,7. . It then travels along and innervates the serratus anterior muscle (SA). EXAMINATION The most common formation of the LTN was the contribution of three branches that originated from the fifth, sixth, and seventh cervical ventral roots. Spinal Cord Segments And Spinal Roots vanat.cvm.umn.edu Apply ice in acute cases to the thoracic spine to help reduce pain and associated muscle spasm. Nerves exiting the area of the thoracic spine provide sensation and motor control to the back, trunk, chest, arms and internal organs. Key Points: Innervates the serratus anterior muscle. The thoracic spine has 12 nerve roots (T1 to T12) on each side of the spine that branch from the spinal cord and control motor and sensory signals mostly for the upper back, chest, and abdomen. Anti-inflammatory drugs and other pain medication. This nerve provides motor innervation to the serratus anterior muscle . It then travels along and innervates the serratus anterior muscle (SA). A nerve root is the initial segment of a nerve, where it leaves the central nervous system. When the muscle paralysis is thought to be due to a electrical wiring (neurogenic) problem, the condition is called long thoracic nerve palsy. It traverses the middle scalene muscle in the neck, passes under the brachial plexus and over the first rib. In some people, the root from C7 is absent, and in others, there is a small root of the nerve arising from C8. Save.

The long thoracic nerve forms from three smaller nerves within the middle scalene muscle and passes over the midportion of the first rib. The roots from C5 and C6 pierce through the medial scalene muscle to join the C7 nerve root. RADIAL NERVE .

The long thoracic nerve (LTN) is a motor nerve that innervates the serratus anterior muscle. the long thoracic nerve is also known as the external respiratory nerve of bell or posterior thoracic nerve, it arises from the superior trunk of the brachial plexus after which it descends posterior to the brachial plexus and anterior to the posterior scalene muscle, passes over the 1st rib, descends along the lateral aspect of the thoracic wall

The electrical signals to control the serratus anterior muscle are transmitted via the long thoracic nerve (LTN). The nerve descends posterior to the roots of the brachial plexus and anterior to the scalenus posterior muscle and has a long course along the chest wall in the mid-axillary line to lie on the . These nerve roots commence deep to the scalenus medius muscle to form the trunk of the long thoracic nerve.

It is responsible for the innervation of the serratus anterior muscle; the long thoracic nerve descends posteriorly to the roots . In a small percentage of population (approximately 10%), the long thoracic nerve receives supply from C 8 nerve root as well. The brachial plexus is divided into five roots, three trunks, six divisions (three anterior and three posterior), three cords, and five branches.There are five "terminal" branches and numerous other "pre-terminal" or "collateral" branches, such as the subscapular nerve, the thoracodorsal nerve, and the long thoracic nerve, that leave the plexus at various points along its length. runs downward & pases anterior to scalenus posterior muscle.
