What else can I help you with?
What structure on the humerus is most medial?
The medial epicondyle is the most medial structure of the humerus. The trochlea is the second.
What is flexion adduction and medial rotation of the humerus are accomplished by?
Flexion, adduction, and medial rotation of the humerus are primarily accomplished by the actions of several muscles, including the pectoralis major, deltoid, and latissimus dorsi. The pectoralis major contributes to both flexion and adduction, while the deltoid assists in flexion and medial rotation. Additionally, the latissimus dorsi plays a significant role in adduction and medial rotation of the humerus. Together, these muscles coordinate to facilitate these movements at the shoulder joint.
What is the descriptive form of scapula?
The scapula is a flat, triangular-shaped bone situated on the upper back. It has three borders (superior, medial, and lateral) and three angles (superior, inferior, and lateral). The scapula articulates with the clavicle and humerus to form the shoulder joint.
The lateral tip of the shoulder is the what Part of the scapula?
The medial border of the scapula is at the medial end of the spine of the scapula. This border is also called the vertebral border.
What structure connecting the pectoral muscle to the humerus?
The structure connecting the pectoral muscle to the humerus is the tendon of the pectoralis major muscle. This tendon attaches the muscle to the upper arm bone (humerus), allowing for movements like shoulder flexion, adduction, and medial rotation.
Clavicle bone articulates with?
the medial end articulates with the sternum and the distal end articulates with the humerus and scapula.
What is the distal medial process of the humerus?
The trochlea is the medial process of the humerus. The humerus articulates with the ulna at the trochlea.
What structure on the humerus is most medial?
The medial epicondyle is the most medial structure of the humerus. The trochlea is the second.
What bone articulates with the clavicle and the humerus at the shoulder?
The Scapula articulates with the humerus and clavicle to make the shoulder socket.
Is the ulna proximal or distal to the radius in directional position?
The humerus is proximal to the radius. The humerus is the upper arm bone, and the radius is the main bone of the forearm.
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.
Is the medial epicondyle adjacent to trochlea?
The medial epicondyle (on the humerus) is located closet to the body when in the anatomical position and the trochlea (on the humerus) is located slightly laterally and inferior to the medial epicondyle.
What two joints are formed containing the medial and lateral ends of the clavicle?
The sternoclavicular joint is formed by the medial end of the clavicle and the sternum, while the acromioclavicular joint is formed by the lateral end of the clavicle and the acromion process of the scapula.
What bone is the bone in your shoulders?
Your shoulder is made up of the humerus, scapula and the clavicle
What muscle has the origin of the clavicle and the insertion of the humerus?
Tricep
What three bones meet at the shoulder?
The upper arm bone (humerus), the collarbone (clavicle), and the shoulder blade (scapula) meet at the shoulder joint.
Which end of the clavicle is closer to the heart?
Medial end
