Which muscle is found attached to the posterior surface of the scapula?
The trapezius and posterior deltoid muscles attach to the surface of this prominent elevation..
What posterior muscles support the scapula?
The posterior muscles include the trapezius, rhomboid major, and rhomboid minor. When the rhomboids are contracted, your scapula moves medially, which can pull the shoulder and upper limb posteriorly. Figure 7.26.

Which muscle is the most inferior muscle on the posterior side of the scapula?
The infraspinatus muscle is below the spine of the scapula. The relatively thin teres minor muscle is the most inferior of the rotator cuff muscles. The three posteriorly-positioned muscles of the rotator cuff are shown in Figure 9-2.
What 17 muscles attach to the scapula?
Each scapula has 17 muscles attached to it: 1. Posteriorly, from superficial to deep: trapezius, rhomboid major, rhomboid minor, supraspinatus, infraspinatus, levator scapulae, teres minor, teres major, latissimus dorsi, serratus anterior, and subscapularis. 2.
What are the muscles attached to the scapula?
The scapula provides attachment to several groups of muscles. The intrinsic muscles of the scapula include the rotator cuff muscles, teres major, subscapularis, teres minor, and infraspinatus.
What muscles are under the scapula?
The intrinsic muscles of the scapula include the rotator cuff muscles, teres major, subscapularis, teres minor, and infraspinatus. These muscles attach the scapular surface and assist with abduction and external and internal rotation of the glenohumeral joint.
What are the muscles present on the posterior aspect of shoulder?
The intrinsic muscles of the posterior group include the deltoid, teres major and the muscles of the rotator cuff. Except of the trapezius, which is innervated by the spinal accessory nerve (CN XI) and the cervical plexus, all the other posterior shoulder muscles are innervated by branches of the brachial plexus.
What are the muscles of the scapula?
Which muscle does not extend from the posterior surface of the scapula to the greater tubercle of the humerus?
The fourth muscle of the rotator cuff (subscapularis muscle) does not attach to the greater tubercle, but instead attaches to the lesser tubercle.
Which muscles are located on the posterior body?
The posterior muscles include the trapezius, rhomboid major, and rhomboid minor. When the rhomboids are contracted, your scapula moves medially, which can pull the shoulder and upper limb posteriorly.
What is a posterior muscle?
The posterior chain muscles live on the backside of your body and include the glutes, hamstrings, calves, erector spinae, lats, and rear shoulder muscles.
