Front 32

Bone embedded in a tendon

Back 32

Patella; sesamoid bone

Front 33

These two bones form the origin of the triceps muscle:

Back 33

Scapula and humerus

Front 34

Bone that forms a pivot joint with the atlas

Back 34

Axis;c2

Front 35

Bone that forms a functional hinge joint with the scapula:

Types of fibrous(fibrous connective tissue) joints:

Back 39

Syndesmosis, sutures, gomphosis

Front 40

Syndesmosis(fibrous) joint definition & example:

Back 40

joint with little movement, limited by a tight ligament and united by fibrous tissue; splint and cannon bone of the horse, tibia-fibular joint

Front 41

Sutures(fibrous) joint definition and example:

Back 41

limited to the skull, necessary for growth, ossify with age

Front 42

Gomphosis(fibrous) joint definition and example:

Back 42

peg and socket joints like teeth and jaws; maintained by the periodontal ligament which only gives a little to absorb shock
