Questions and Answers

What is the function of the scapula in the shoulder region?

  • It forms a conventional articulation with the trunk
  • It houses the greater tubercle
  • It provides points of attachment for extrinsic and intrinsic muscles (correct)
  • It articulates with the ulna and radius to form the elbow
  • How is the scapular cartilage described?

  • Non-existent in dogs
  • Thick and weight-bearing
  • Highly articulated with the trunk
  • Comprised of only a very narrow rim (correct)
  • What is the role of the clavicle in the forelimb?

  • A remnant of bone may remain embedded in the fibrous intersection in the brachiocephalicus (correct)
  • It articulates with the scapula to form the shoulder
  • It provides a site of attachment for brachialis and biceps brachii muscles
  • It is absent in larger species

    Study Notes

    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.
