Saddle joint | Allows primates to flex, extend, abduct, adduct, and circumduct the thumb. |
Ligament | A band of fibrous connective tissue that connects one bone to another to help stabilize joints. |
Tendon | A band of fibrous connective tissue that connects muscle to bone to help the animal move. |
Bursa | A fibrous sac that acts as a cushion to ease movement in areas of friction. |
Synovial membrane | Inner lining of bursae and synovial joints which secretes synovial fluid as a lubricant to make joint movement smooth. |
Axial skeleton | The framework of the body. Includes skull, auditory ossicles, hyoid bones, vertebral column, ribs, and sternum. |
Appendicular skeleton | The framework of the body that consists of the extremeties, shoulder, and pelvic girdles. (Appendages.) |
Cranium | The portion of the skull that encloses the brain. |
Frontal | Forms the roof of the cranial cavity, or "front" or cranial portion of the skull. |
