This process serves as a point of attachment for the biceps brachii muscle. Supraglenoid Tubercle: A cranially pointing process found close to the cranial aspect of the glenoid cavity.Subscapular Fossa: A smooth portion of the medial surface of this bone.Spine: A bony ridge that divides the lateral surface of this bone into the supraspinous and infraspinous fossae.The serratus ventralis muscle attaches here. Serrated Surface: A rough dorsal portion of medial surface of this bone.It serves as a point of attachment for infraspinatus muscle. Infraspinous Fossa: A depressed area caudal to the spine.Articulates with the joint capsule of the shoulder joint. Infraglenoid Tubercle: A caudally pointing process found close to the caudal aspect of the glenoid cavity.This cavity is covered by hyaline (articular) cartilage in a live animal. Articulates with the head of the humerus to form a shoulder joint.
Glenoid Cavity: An articular cavity of the scapula.Dorsal Border: Dorsal edge of this bone with bearing a small scapular cartilage in a live animal closest to the dorsum (back).Cranial Border: Curved cranial edge of this bone closest to the head.Caudal Border: Relatively straight caudal edge of this bone closest to the tail.Acromion: An enlarged distal end of the spine.
