7AB. Pectoral Girdle and Upper Arm - Bones and Bone Landmarks

Flashcards covering the bones and landmarks of the pectoral girdle and upper arm, including the clavicle, humerus, and scapula, along with notable features and definitions.

Clavicle

A bone that connects the arm to the body; also known as the collarbone.

Humerus

The long bone of the upper arm or forelimb.

Sternal end

The end of the clavicle that articulates with the sternum.

Acromial end

The end of the clavicle that articulates with the acromion of the scapula.

Shaft

The long central part of a bone.

Conoid tubercle

A prominence on the clavicle which serves as an attachment point for ligaments.

Coracoclavicular ligaments

Ligaments including the conoid and trapezoid ligaments that connect the clavicle to the coracoid process of the scapula.

Scapula

Also known as the shoulder blade; a flat, triangular bone that forms the back of the shoulder.

Acromion

A bony process on the scapula where the clavicle connects.

Coracoid process

A hook-like structure on the scapula that serves as an attachment point for muscles and ligaments.

Glenoid fossa/cavity

The shallow cavity in the scapula that articulates with the head of the humerus.

Greater tubercle

A prominent area on the humerus that serves as an attachment point for muscles.

Bicipital groove

A groove located between the greater and lesser tubercles of the humerus.

Deltoid tuberosity

A raised area on the humeral shaft for the attachment of the deltoid muscle.

Medial epicondyle

A bony prominence on the lower part of the humerus on the side closest to the body.

Lateral epicondyle

A bony prominence on the lower part of the humerus on the outer side.

Anatomical neck

The area of the humerus that separates the head from the shaft.

Surgical neck

The area of the humerus just below the tubercles where fractures commonly occur.

Infraglenoid tubercle

An elevated area located below the glenoid cavity of the scapula providing attachment for muscles.

Supraglenoid tubercle

An elevated area above the glenoid cavity of the scapula serving as an attachment for muscles.
