a slender bone that connects the manubrium of the sternum to the scapula, The "collar" bone., lateral end is called the acromial extremity and articulates with the acromion of the scapula (acromioclavicular joint)
medial end is called the sternal extrimity and articulates with the manubrium (sternoclavicular joint)
helps create the jugular notch
body is area between the two extremities
female bone is usually shorter and less curved
form the pectoral girdle on both sides of the body, triangular flat bones that form the shoulder joint, Wing Bone
Scapula Glenoid Fossa
Articular surface located on the lateral surface of the scapula and fits the head of the humerus.
Scapula coracoid process
This portion of the scapula extends anteriorly then laterally to serve as attachments for shoulder stabilizing muscles and ligaments. It does not articulate with a condyle.
Scapula acromion process
This process articulates with the clavicle. It is also a continuation of the scapular spine and hooks over anteriorly
Single bone that runs between the shoulder and elbow
Perforated by numerous vascular foramina, this portion of the humerus proves for the attachment of the articular capsule of the shoulder joint
Articulates with the glenoid cavity on the scapula and with the radius and ulna in the region of the elbow
Humerus greater tubercle
One of two eminences on the upper extremity of the humerus and positioned laterally to the head. Gives insertion to the supraspinatus muscle; the middle to the infraspinatus muscle; the lowest one, and the body of the bone for about 2.5 cm. below it, to the teres minor muscle.
Humerus lesser tubercle
One of two eminences on the upper extremity of the humerus and positioned medially and extends anteriorly. Serves as impression for the insertion of the tendon of the subscapularis muscle.
Humerus medial epicondyle
Located on the lower extermity. Larger and more prominent than its sibling epicondyle. Attachment to the Pronator teres/ Flexor muscles of the forearm. Gives attachment to the ulnar collateral ligament of elbow joint.
Humerus lateral epicondyle
Located on the lower extremity of the Humerus. Small, tuberculated eminence
attachment to the radial collateral ligament of the elbow-joint, and to a tendon common to the origin of the Supinator and some of the Extensor muscles.
The lateral portion of the articular surface of the Humerus' lower extremity. It articulates with the cupshaped depression on the head of the radius, and is limited to the front and lower part of the bone.
Located on the medial portion of the Humerus' lower extremity. It articulates with the ulna.
Humerus olecranon fossa
Above the back part of the trochlea of the humerus is a deep triangular depression, the _, in which the summit of a process is received in extension of the forearm.
Humerus coronoid fossa
Superior to the trochlea portion of the Humerus. It receives the _ process of the ulna. It is directly adjacent to the radial fossa of the Humerus
This bone articulates with the capitulum of the humerus. It is located laterally on the forearm. Lower extremity contributes the greater portion of the wrist joint.
This bone mainly articulates with the trochlea of the Humerus forming the majority of the elbow joint. It is located medially in the forearm of the anatomical position.
Ulna trochlear notch
Landmark of ulna Humeroulnar joint articulates with the trochlea of the humerus. Hinge Joint allowing for Flexion/extension. _ articulates with the Trochlea of the Humerus.
Ulna olecranon process
Insertion for anconeus,triceps brachii. Origin for one head of the flexor carpi ulnaris. Fit into the Olecranon fossa of Humerus.
Ulna coronoid process
The _ is a triangular eminence projecting forward from the upper and front part of the ulna. Meets the _ fossa on the medial side of the Humerus
