Which of these muscles attaches to scapula?
The scapula provides attachment sites for many muscles including the pectoralis minor, coracobrachialis, serratus anterior, triceps brachii, biceps brachii, and the subscapularis. The scapula has two main surfaces: the costal (front facing) surface and the dorsal (rear facing) surface.

What are the rhomboid muscles?
The rhomboids are a collective group of muscles formed by the rhomboid major and minor. The rhomboids are important in upper limb movement and stability of both the shoulder girdle and scapula. Both rhomboids receive innervation from the dorsal scapular nerve and supplied by the dorsal scapular artery.
Which of the following are muscles that move the glenohumeral joint that originate on the scapula?
The most important shoulder muscles are the four rotator cuff muscles – the subscapularis, supraspinatus, infraspinatus and teres minor muscles – which connect the scapula to the humerus and provide support for the glenohumeral joint.
What muscles pull scapula down?
The rhomboids are rhombus-shaped and are used to pull the shoulder blades together. They also rotate the scapula in a downward direction and provide stability for your shoulders.Where is the scapula muscle?
The scapula, or shoulder blade, is a large triangular-shaped bone that lies in the upper back. The bone is surrounded and supported by a complex system of muscles that work together to help you move your arm.

Article first time published onWhich muscle will depress the scapula or elevate the ribs?
Pectoralis minor draws the scapula forward and downward, and raises the ribs in forced inspiration. The subclavius muscle is a small muscle that lies deep to pectoralis major muscle.
Which of the following muscles originates on the scapula and inserts into the humerus?
Teres Major: The teres major is a thick flattened muscle connecting the lower scapula with the humerus. Attachments: Originates from the posterior of the scapula and attaches to the humerus. Actions: Adducts the shoulder and assists in rotation of the arm.
Which muscle originates on the anterior surface of the scapula and inserts on the lesser tubercle?
On the anterior side of scapula bone is a single muscle, the subscapularis. It is triangular in shape and covers the entire bone. Its origin is along the fossa that makes up most of the “wing” of the scapula and it inserts on the lesser tubercle of the humerus bone. The subscapularis muscle is shown in Figure 9-1.

What is the muscle on top of your shoulder called?
The largest of these shoulder muscles is the deltoid. This large triangular muscle covers the glenohumeral joint and gives the shoulder its rounded-off shape. It stretches across the top of the shoulder from the clavicle in the front to the scapula in the back.
Which of the muscles that move the glenohumeral joint attach to the scapula quizlet?
Which of the muscles that move the glenohumeral joint attach to the scapula? The biceps brachii, triceps brachii, and the rotator cuff muscles attach to the scapula.
What is the origin of the rhomboid major muscle?
OriginRhomboid minor: Nuchal ligament, Spinous processes of vertebrae C7-T1 Rhomboid major: Spinous process of vertebrae T2-T5InsertionRhomboid minor: Root (medial end) of spine of scapula Rhomboid major: Medial border of scapula (from inferior angle to root of spine of scapula)
Why does my rhomboid muscle hurt?
You may develop rhomboid muscle pain as a result of: poor or incorrect posture. sitting for extended periods. injuries from straining, overstretching, or tearing the muscles.
What muscles attach to the medial border of the scapula?
Four muscles attach to the medial border. Serratus anterior has a long attachment on the anterior lip. Three muscles insert along the posterior lip, the levator scapulae (uppermost), rhomboid minor (middle), and to the rhomboid major (lower middle).
What exercises strengthen scapular muscles?

What muscle and or muscles elevate depress retract and protract the scapula 6 muscles?
The trapezius elevates, depresses, and retracts the scapula. The descending muscle fibers of the trapezius muscle internally rotate the arms. The transverse muscle fibers retract the scapulae, and the ascending muscle fibers medially rotate the scapulae.
What muscle raises ribs in forceful inhalation or pulls scapula forward and downward?
Pectoralis major. Raises ribs in forceful inhalation or pulls scapula forward and downward. Pectoralis minor. Used to thrust shoulder anteriorly (protraction), as when pushing something.
Which muscle can be involved in elevation depression and upward rotation of the scapula?
The trapezius functions include upward rotation and elevation for the upper trapezius, retraction for the middle trapezius, and upward rotation and depression for the lower trapezius.
What tendons are in scapula?
The glenohumeral joint is where the ball (humeral head) and the socket (the glenoid) meet. The rotator cuff connects the humerus to the scapula and is made up of the tendons of four muscles, the supraspinatus, infraspinatus, teres minor and the subscapularis. Tendons attach muscle to bone.
Which muscle originates on the sternum and clavicle?
There are two such muscles on each side of the sternum (breastbone) in the human body: pectoralis major and pectoralis minor. The pectoralis major, the larger and more superficial, originates at the clavicle (collarbone), the sternum, the ribs, and a tendinous extension of the external oblique abdominal muscle.
What muscle is above the scapula?
On the back, there are two muscles below the scapular spine, and one above it. The one above is supraspinatus. It arises from almost all of the supraspinous fossa. It passes under the acromion and inserts here, on the greater tubercle.
