The trapezius, levator scapulae, and rhomboids originate from the base of the skull and/or spine and connect the scapula and clavicle to the trunk of the body.

What muscles are attached to the clavicle?
The clavicle is an S-shaped bone that is anchored by strong ligamentous attachments on both its medial and lateral ends. Muscular attachments to the clavicle include the sternocleidomastoid, pectoralis major, and subclavius muscles proximally and the deltoid and trapezius muscles distally.
What muscles does the scapula attach to?
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 8 muscles that 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.
How many muscles attach to the scapula?
17 different muscles
It connects with the humerus at the glenohumeral joint as well as the clavicle at the acromioclavicular joint to form the shoulder joint. In total, 17 different muscles attach to the scapula, which makes it difficult to fracture.
How many muscles are attached with clavicle?
A total of six muscles are attached to the clavicle, found distributed at either the lateral third or medial two thirds of the bone. Two muscles are attached to the lateral third of the clavicle: The trapezius muscle, which is attached along the posterior surface of the bone.
Where does clavicle attach to scapula?
The acromioclavicular joint connects the clavicle to the acromion, which is part of the shoulder blade or scapula.
How many muscles attach on scapula?

|---|---|
| Processes | Coracoid, acromion |
| Muscles that originate from scapula | Deltoid, supraspinatus, infraspinatus, triceps brachii (long head), teres minor, teres major, latissimus dorsi, coracobrachialis, biceps brachii, subscapularis, omohyoid muscles |
How many muscles are attached to the scapula?
What part of scapula articulates with the clavicle?
acromion
At its lateral end the spine gives rise to this flat, angulated projection, the acromion, which stands completely clear of the bone. The clavicle articulates with the scapula here, at the tip of the acromion. This other projection, looking like a bent finger, is the coracoid process.
How many muscles attach to the shoulder?
eight muscles
Also called the glenohumeral joint, it has more range of motion than any other joint in your body. There are about eight muscles in your shoulder that support this joint. They give it strength, stability and shape. Your shoulder muscles are skeletal muscles.
How many muscles are attached to scapula?
What part of the scapula articulates with the clavicle?
What part of scapula articulates with the clavicle quizlet?
The acromion of the scapula articulates with the clavicle.
How does the clavicle attach to the scapula?
The lateral end of the clavicle articulates with this projection on the scapula, the acromion, forming the acromio-clavicular joint. Apart from this one very movable bony linkage, the scapula is held onto the body entirely by muscles.
What muscles attach to the clavicle?
Muscle Attachments of the Clavicle Front (anterior border) – pectoralis major muscle Back (posterior border) – sternocleidomastoid muscle, sternohyoid muscle and trapezius muscle. Top (superior surface) – deltoid muscle and trapezius muscle.
What muscles are in the scapula?
Two more muscles that are inserted into the scapula are the Serratus anterior and the Pectoralis minor. The Serratus anterior is inserted to the whole length of the medial border of the scapula, anterior to the three other muscles mentioned above.
What nerves are involved in the scapular flexion?
A: depresses the scapula, downwardly rotates the scapula, assists to protect the scapula from a retracted position, stabilizes the scapula B: lateral thoracic artery N: medial pectoral nerve, C8, T1
What are the clavicle and scapula bones?
In this anatomy lesson, I’m going to cover the clavicle and scapula bones. These bones are part of the appendicular skeleton, and together they form the pectoral girdle (also called shoulder girdle), which attaches the upper limb to the axial skeleton.
