|---|---|
| Articulations | joint |
| Hematopoiesis | blood cell formation, found in red bone marrow |
| Red bone marrow | soft connective tissue inside the hard walls of some bones |
| Diaphysis | shaft of long bone |
| Medullary cavity | hallow area inside the diaphysis of a bone |
| yellow bone marrow | an inactive fatty form of marrow found in the adult skeleton |
| Epiphysis | ends of bones, red bone marrow fills in small spaces n the spongy bone composing the epiphysis. |
| Articular cartilage | cartilage covering the joint ends of bones |
| Periosteum | tough, connective tissue covering the bone |
| Endosteum | a fibrous membrane that lines the medullary cavity. |
| Dense Bone | bone with an outer layer that is hard and dense. |
| Compact bone | dense bone |
| Trabeculae | needlike threads of spongy bone that surround a network of spaces |
| Osteons | structural unit of compact bone tissue made up of concentric layers (lamellae)of hard bone matrix and bone cells (osteocytes) |
| concentric lamella | ring of calcified matrix surrounding the haversian canal |
| osteocyte | bone cell |
| lacunae | space or cavity; for example lacunae in bone contain bone cells |
| canaliculi | an extremely narrow tubular passage or channel in compact bone |
| periosteum | tough, connective tissue covering the bone |
| cartilage | specialized, fibrous connective tissue that has the consistency of a firm plastic or gristle like gel |
| Chondrocytes | cartilage cell |
| Osteoblasts | bone forming cell |
| Osteoclasts | bone absorbing cell |
| Endochondral Ossification | the process in which most bones are formed from cartilage models |
| Epiphyseal plate | the cartilage plate that is between the epiphysis and the diaphysis and allows growth to occur; sometimes refered to as the growth plate |
| Epiphyses | ends of a long bone |
| Diaphysis | shaft on a lone bone |

| Middle Ear | a tiny and very thin epithelium lined cavity in the temporal bone that houses the ossicles; in the middle ear, sound waves are amplified |
| Sinuses | a space or cavity inside some of the cranial bones |
| Paranasal Sinuses | four pairs of sinuses that have openings into the nose |

| Clavicle | collarbone, connects the upper extremity to the axial skeleton |
| Olecranon Fossa | a large depression on the posterior surface of the humerus |
| Sternoclavicular Joint | the direct point of attachment between the bones of the upper extremity and the axial skeleton |
| Radius | one of the two bones in the forearm; located on the thumb side of the forearm |
| Ulna | one of the two forearm bones; located on the little finger side |
| Olecranon Process | the large bony process of the ulna; commonly referred to as the tip of the elbow |
| Carpal | pertaining to the wrist |
| Meta-carpal | the part of the hand between the wrist and fingers |
| Phalanges | the bones that make up the fingers and toes |
| Hip | the joint connecting the legs to the trunk; pelvic girdle |

| Coxal | pelvic bone or hip bone formed by fusion of three distinct bones (ilium, ischium, and pubis) during skeletal development |
| Ilium | distal portion of the small intestine |
| Ischeum | one of three separate bones that forms the os coxa |
| Pubis | joint in the midline between the two pubic bones |
| Femur | thigh bone, which is the longest bone in the body. |
| Acetabulum | socket in the hip bone into which the head of the femur fits |
| Patella | small, shallow pan; the kneecap |
| Tibia | shinbone |
| Fibula | the slender non-weight bearing bone located on the lateral aspect of the leg. |
| Metatarsal Arch | the arch that extends across the ball of the foot; also called the transverse arch |
| Tarsals | Seven bones of the heel and back part of the foot; the calcaneus is the largest |
| Calcaneus | heel bone; largest tarsal in the foot |
| longitudinal Arch | two arches, the medial and lateral, that extends lengthwise in the foot |
| ? | / |
| Transverse Arch | the arch that extends across the ball of the foot also known as the Metatarsal Arch |
| Metatarsal Arch | the arch that extends across the ball of the foot also known as the Transverse Arch |
| ? | / |
| Synarthrosis | a joint in which fibrous connective tissue joints bones and holds them together tightly; commonly called sutures |
| Amphiarthrosis | slightly movable joint such as the joint joining the two pubic bones |
| Diarthroses | freely movable joint |
| Ligaments | bond or band connecting two objects; in anatomy a band of white fibrous tissue connecting bones |
| Articular Cartilage | cartilage covering the joint ends of bones |
| Synovial Membrane | connective tissue membrane lining the spaces between bones and joints that secretes synovial fluid |
| Flexion | act of binding; decreasing the angle between two bones at the joint |
| Extension | increasing the angle between two bones at a joint |
| Rotation | movement around the longitudinal axis; for example, shaking her head "no" |
| Flex | act of binding; decreasing the angle between two bones at the joint |
| Extend | straighten a bend |
