What is the insetion of the trapezius muscle?
Spine of the Scapula Acromion Clavicle
What structures are related to lateral end of the spine of the scapula?
Scapula is very interesting bone. It holds the upper limb, but have no bony attachment to your thorax. It is attached to thorax, through the collar bone or the clavicle. Lateral end of the clavicle is attached to the lateral end of the spine of the scapula. On the inside of the spine of the scapula and clavicle, you have insertion of the muscle called as trapezius. From out side of this, you have origin of the deltoid muscle. Technically and mechanically, the trapezius muscle continues as deltoid muscle.
Which muscle stabilizes the scapula by preventing extreme elevation and protraction of the clavicle?
Subclavius
What muscle originates on the anterior surface of the scapula and inserts on the proximal anterior humerus?
The subscapularis muscle originates on the anterior surface of the scapula and inserts on the proximal anterior humerus. Its function is to rotate the head of the humerus medially.
What is the difference between palpating a bony landmark and a muscle?
When you palpate a bony landmark, it will feel harder than the soft tissue around it. For example, feel the point of your shoulder (acromion process of the scapula). Now move more medially (toward the center of your body) to the space between your shoulder and neck. If you feel the front of your body in this area, you will feel the clavicle (collarbone). If you feel the back of the area, you will be on your trapezius muscle, and perhaps supraspinatus and levator scapula. Notice how much softer the muscle areas feel than the bony landmarks. Generally, a bony landmark is a specific place on a particular bone. To use the example above - the acromion process of the scapula - it is the most lateral and superior aspect of the scapula, not just any old place on the scapula.
What muscle originates on scapula and proximal humerus and inserts on olecranon process?
The triceps originates on the scapula and proximal humerus and inserts on the olecranon process. The muscles has three heads (hence its name) so it has multiple origins.
Which of these phrases most aptly describes muscle insertion?
The phrase tendon attachment that moves most aptly describes muscle insertion. The trapezius muscle inserts on the acromion and scapular.
What upper arm muscle is named for its shape often the site of injections that abducts and rotates the arm is?
injections are normally given in the deltoid muscle which attaches to itself to the scapula and acromion
Name 3 muscles on the upper arm and shoulder?
Many muscles are attached to shoulder girdle. You have trapezius, deltoid muscles attached to spine of the scapula and clavicle. Rhomboid major and minor muscles and serratus anterior muscle attached to the medial border of the scapula. You have subscapularis, supraspinatus, infraspinatus muscles attached to the inner and outer surfaces of the scapula. You have teres minor and major muscles attached to lateral border of the scapula. You have pectoralis major muscle (clavicular head) attached to clavicle. You have biceps muscle attached to coracoid process and supraglenoid tubercle of the scapula. you have long head of triceps attached to infraglenoid tubercle of the scapula. you have pectoralis major muscle attached to coracoid process of the scapula.You have subclavius muscle attached to clavicle.
What bone do the muscles of the rotator cuff originate?
The rotator cuff muscles are referred to occasionally as the SITS muscles. The Supraspinatus, Infraspinatus, Teres minor and the subscapularis. The Supras. originates on the scapula and inserts on the humerus. The Infras. originates on the scapula and inserts on the humerus(greater tubercle. The Teres minor originates on the scapula and inserts on the humerus. The Subscapularis originates on the scapula and inserts on the humerus(lesser tubercle). The function of this muscle group is to stabilize the shoulder joint. Hope this helps.
What large muscle originates along the sternum and inserts onto the humerus?
You have the pectoralis major muscle in the chest wall. It arise from the sternum and the clavicle. It is inserted on the lateral part of the bicipital groove.
What muscle occupies the fossa above the spine of the scapula?
The muscles that occupy the fossa, just above the spine of the scapula are the Trapezius muscles. These muscles are so named by the way they can swing the arm back and forth from the front to the back.
