Lab #1-Musculoskeletal General Concepts

A set of vocabulary flashcards covering basic musculoskeletal terminology and specific bone structures of the dog thoracic limb, based on lecture lab notes.

Proximal end

The end of a bone close to the trunk, also known as the proximal epiphysis.

Distal end

The end of a bone away from the trunk, also known as the distal epiphysis.

Diaphysis

The shaft of a long bone located between the epiphyses.

Nutrient foramen

The opening in a bone that serves as the main blood supply.

Trabecular

The material that spongy bone is made of.

Cortacal bone

Bone that is thick in the diaphysis.

Medullary Cavity

A cavity found only in long bones, which reg/shortbones do not have.

Endosteum

A membrane that covers the inside of cortacal bone and trabecular.

Periosteum

The membrane located on the outside of the bone.

Physis

The growth plate of the bone.

Supraglenord tubercle

An eminence on the scapula.

Coracodsat process

A specific process located on the scapula.

Infra glenoid tuberde

A bony eminence found on the scapula.

Supraspinatus muscle

A muscle that inserts on the humerus.

Lateral epicondyle

An eminence on the humerus that serves as the attachment for extensor muscles.

Antibrachium

The region of the thoracic limb that includes the radius and ulna.

Radius

The main weight-bearing ($\text{wb}$) bone of the antibrachium.

Olecranon tuber

The tuber on the ulna that serves as the site for the triceps brachi insertion.

Ungreal creast

A bony prominence on the distal phalanx of digit $4$ associated with the unguis (claw).

Extensor process

A process for extensor tendons located on the dorsal side of the distal phalanx.

Flexor process

A process located on the palmar side of the distal phalanx.

Sesamoid bones

Bones identified as cartilage in the musculoskeletal assembly.
