skeletal system
| Term | Definition |
|---|---|
| axial skeleton | the adult axial skeleton has 80 bones, including the skull, vertebrae, and ribs |
| appendicular skeleton | the adult skeleton has 126 bones, including arms, legs, and pelvic gridle responsible for movement of the Upper extremities, Lower extremities, Clavicles, Scapula, Pectoral girdle |
| ligament | the ligament attach bone to bone for joint stability |
| tendons | the tendons join muscles to bone that helps in moving extremities. tendons in the muscular system help avoid muscle injury by absorbing some of the impact muscles take |
| connective tissue/cartilage | the tissue maintains, protects and gives form to other tissues and organs. cartilage is a part of connective tissue found in the larynx and respiratory tract, also covers and protect the end of the long bone |
| long bones | these bones have epiphysis, diaphysis, and medullary cavities containing yellow bone marrow |
| long bones | femur, humerus, tibia, fibula, ulna, radius |
| short bones | these are found in the wrists and ankles. Short bones are typically small and round. the provide stability and support with limited movement |
| sesamoid bones | these small round bones are found in joints that are held in places by tendons |
| irregular bones | these include bones with unusual shape that is typically related to its function |
| carpals and tarsals bones are | short bones |
| vertebrae and pelvis, ears, hyoid(neck) skulls are | irregular bones |
| patellas bones are | sesamoid bones |
| red bone marrow | found within bones, marrow is responsible for producing new blood cells this process is known as hematopoiesis. bones also store calcium, which is essential for proper cell function |
| scapula | upper appendicular skeleton |
| clavicle | upper appendicular skeleton |
| humerus | upper appendicular skeleton |

| true ribs | 7 pairs |
| false ribs | 3 pairs |
| floating ribs | 2 pairs |
| xiphoid process | located at the end of the sternum |
| male pelvic girdle | faunal shape narrow heavy and strong more longer and veritable |
| female pelvic gridle | basic shape wider and rounder, lighter and Brouder to support pregnancy and child birth |
| calcaneus | lower appendicular skeleton |
| spinal cord | axial skeleton |
| frontal bone | axial skeleton |
