19 Σεπ 2023 · Under innervation from the dorsal scapular nerve, the rhomboids primarily retract the scapula superomedially and rotate the glenoid cavity. Therefore, the rhomboids are important to stabilize the scapula into position and reinforce the shoulder. This article will discuss the anatomy and function of the rhomboid muscles.
2 Ιαν 2023 · Rhomboid Major. The rhomboid major is an extrinsic muscle of the shoulder. It is located deep to the trapezius, and inferior to the rhomboid minor. Attachments: Originates from the spinous processes of T2-T5 vertebrae. Attaches to the medial border of the scapula, between the scapula spine and inferior angle.
Function. The rhomboid major helps to hold the scapula (and thus the upper limb) onto the ribcage. Other muscles that perform this function include the serratus anterior and pectoralis minor. Both rhomboids (major and minor) also act to retract the scapula, pulling it towards the vertebral column.
28 Ιουν 2023 · The rhomboid major muscle connects the thoracic spine with the scapula as it extends between the spinous processes and the scapular border. This location is vital to the functioning and the structure of the shoulder and upper arms.
Function. The rhomboid major and minor are a group of deep intrinsic shoulder muscles that together with the sternocleidomastoid, trapezius, pectoralis muscles, latissimus dorsi, and serratus anterior, form the shoulder girdle.
20 Δεκ 2022 · The rhomboid major is a muscle in the upper back that controls the position and movement of the scapula. It helps to stabilize the scapula, elevate the shoulder, and support the spine. Learn about its structure, location, and possible injuries.
