| acromion | outward extension of shoulder blade forming point of shoulder. Overlies the shoulder joint and articulated with clavicle |
| articular cartilage | thin layer of cartilage covering the bone in the joint space |
| bone | dense, hard connective tissue composing skeleton. Ex: femur - long bone, carpal - short bone, scapula - flat bone, patella - sesamoid |
| calcium | one of the minerals of bones - Calcium phosphate is major calcium salt in bones |
| cancellous bone | spongy, porous, bone tissue in the inner part of bone |
| cartilage | flexible, rubbery connective tissue = found in immature (child's) skeleton at the epiphyseal growth plate and on joint surfaces |
| collagen | dense, connective tissue protein strands found in bone & tissues |
| compact bone | hard, dense bone tissue, usually found ~ outer portion of bones |
| condyle | knuckle-like process at end of bone near a joint |
| cranial bones | skull bones: ethmoid, frontal, occipital, parietal, sphenoid and temporal |
| diaphysis | shaft or mid-portion of long bone |
| disk (disc) | flat round plate-like structure - intervertebral disk is a fibrocartilaginous substance b/w 2 vertebrae |
| epiphyseal plate | cartilaginous area at the ends of long bones where lengthwise growth takes place in immature skeleton (child's) |
| epiphysis | each end of long bone, area beyond epiphyseal plate |

| fissure | narrow, slit-like opening in or b/w bones |
| fontanelle | soft spot (incomplete bone formation) b/w skin bones of an infant |
| formen | opening or passage in bones where blood vessels & nerves enter & leave. |
| formen magnum | opening of the occipital through which the spinal cord passes |
| fossa | shallow cavity in a bone |
| haversian canals | minute spaces filled with blood vessels - found in compact bone |
| malleolus | round process on both sides of ankle joint. Lateral malleolus is part of fibula, media malleolus is part of tibia |
| manubrium | upper portion of sternum - articulates w the medial aspect of clavicle |
| mastoid process | round projection on temporal bone behind ear |
| medullary cavity | central, hollowed-out area in shaft of long bone |
| metaphysis | flared portion of long bone b/w diaphysis and epiphyseal plate (meta= b/w) |
| olecranon | large process on proximal end of ulna - point of flexed elbow |
| osseous tissue | bone tissue |
| ossification | process of bone formaton |
| osteoblast | bone cell that help form bony tissue - REBUILDS BONE (means - immature bone) |
| osteoclast | bone cell that absorbs & removes unwanted bony tissue - CARRIES AWAY BONE |
| periosteum | membrane surrounding bones = rich in blood vessels & nerve tissue |
| phosphorus | mineral found in bones in combo w/ calcium |
| pubic symphysis | area of confluence (coming tog) of 2 pubic bones in pelvic. (Sym- = together, -physis = to grow) Joined tog by fibrocartilaginous disk |
| red bone marrow | found in cancellous bone - site of hematopoiesis |
| ribs | 12 pairs curved bones form chest wall. True ribs pairs #1 to 7, false ribs #8 to 10, floating ribs pairs #11 & 12 |

| suture | immovable joint b/w bones - e.g. skull (cranium) |
| temporomandibular joint | connection on either side of head b/w temporal bone & mandibular bone |
| trabeculae | supporting bundles of bony fibers in canellous (spongy) bone |
| trochanter | large process at neck of femur, attachment site for muscles and tendons |
| tuberosity | rounded process of bone - attachment site for muscles & tendons |
| vertebra | single spinal bone - composed of vertebral body, vertebral arch, spinous process, transverse process, lamina - encloses neural canal |
| xiphoid process | lower, narrow portion of sternum |
| yellow bone marrow | fatty tissue found in medullary cavity of most adult long bones |
| flexion | decreasing the angle b/w 2 bones, bending a limb |
| extension | increasing the angle b/w 2 bones, straightening out a limb |
| abduction | move away from midline of body |
| adduction | move toward midline of body |
| rotation | circular movement around axis (central point) internal rotation is toward midline and external rotation is away fr midline |
| dorsiflexion | decreasing angle of the ankle joint so foot bends backward (upward) |
| plantar flexion | motion that extends foot downward toward ground when pointing toes or stepping on gas pedal. Plant/o=sole of foot |
| supination | applied to hand and forearm =act of turning palm up |
| pronation | applied to hand and forearm = act of turning palm down |
| fascia | fibrous membrane separating & enveloping muscles |
| insertion of a muscle | connection of muscle to a bone that moves |
| origin of muscle | connection of muscle to stationary bone |
| skeletal muscle | muscle connected to bones - voluntary or striated muscle |
| smooth muscle | visceral muscle |
| striated muscle | skeletal muscle |
| visceral muscle | muscle connected to internal organs - involuntary or smooth muscle |
