Canine Forelimb Anatomy Quiz

Scapula Function

• The scapula serves as the anchor point for the entire shoulder region.

Scapular Cartilage

• The scapular cartilage is described as a thin, flexible, and avant-garde structure.

Clavicle Role

• The clavicle plays a crucial role in the forelimb by providing a bony attachment site for muscles, ligaments, and other soft tissues.

Humerus Articulation

• The humerus articulates with the radius and ulna bones at the elbow joint, enabling various movements in the forelimb.

Muscle Attachment Sites

• The medial aspect of the humerus provides a site of attachment for the brachialis and biceps brachii muscles in the forelimb.

Shoulder Region Formation

• The scapula bone forms the basis of the shoulder region, providing points of attachment for extrinsic and intrinsic muscles.

Humerus Anatomy

• In the human species, the greater tubercle of the humerus is not separated into two parts.

Elbow Joint Articulation

• The humerus bone articulates with the ulna medially via a trochlea and the radius laterally via a capitulum in dogs and cats.

Muscle Attachment Sites

• The medial aspect of the humerus provides a site of attachment for the brachialis and biceps brachii muscles in the forelimb.

Forearm Anatomy

• In the distal region, the ulna shaft lies parallel to the radius.
