List of skeletal muscles of the human body
Muscle Origin Insertion Artery Nerve Action Antagonist
trapezius down the midline , from the external occipital protuberance , the nuchal ligament , the medial part of the superior nuchal line , and the spinous processes of the vertebrae C7-T12 at the shoulders , into the lateral third of the clavicle , the acromion process and into the spine of the scapula transverse cervical artery major nerve supply is the cranial nerve XI . cervical nerves C3 and C4 receive information about pain in this muscle retraction and elevation of scapula Serratus anterior muscle
latissimus dorsi spinous processes of thoracic T6 - T12 , thoracolumbar fascia , iliac crest and inferior 3 or 4 ribs floor of intertubercular groove of the humerus subscapular artery , dorsal scapular artery thoracodorsal nerve pulls the forelimb dorsally and caudally deltoid , trapezius
rhomboids nuchal ligaments , spinous processes of C7-T5 vertebrae medial border of the scapula dorsal scapular artery dorsal scapular nerve ( C4 and C5 ) Retracts the scapula and rotates it to depress the glenoid cavity . fixes the scapula to the thoracic wall Serratus anterior muscle
rhomboid major spinous processes of the T2 to T5 vertebrae medial border of the scapula , inferior to the insertion of rhomboid minor muscle dorsal scapular artery dorsal scapular nerve ( C4 and C5 ) Retracts the scapula and rotates it to depress the glenoid cavity . It also fixes the scapula to the thoracic wall Serratus anterior muscle
rhomboid minor nuchal ligaments and spinous processes of C7- to T1 vertebrae medial border of the scapula , superior to the insertion of rhomboid major muscle dorsal scapular artery dorsal scapular nerve ( C4 and C5 ) Retracts the scapula and rotates it to depress the glenoid cavity . It also fixes the scapula to the thoracic wall Serratus anterior muscle
levator scapulae posterior tubercles of transverse processes of C1 - C4 vertebrae superior part of medial border of scapula dorsal scapular artery cervical nerve ( C3 , C4 ) and dorsal scapular nerve ( C5 ) Elevates scapula and tilts its glenoid cavity inferiorly by rotating scapula

This is a table of skeletal muscles of the human anatomy. There are around 640 skeletal muscles within the typical human body. Almost every muscle constitutes one part of a pair of identical bilateral muscles, found on both sides, resulting in approximately 320 pairs of muscles, as presented
in this article. Nevertheless, the exact number is difficult to define because different sources group muscles differently, e.g. regarding what is defined as different parts of a single muscle or as several muscles. The muscles of the human body can be categorized into a number of groups which include muscles relating to the head and neck, muscles of the torso or trunk, muscles of the upper limbs, and muscles of the lower limbs. The action refers to the action of each muscle from the standard anatomical position. In other positions, other actions may be performed. These muscles are described using anatomical terminology.
