long bone parts articular cartilage, diaphysis, distal epiphysis
# of bones in body 206
Compact bone central canal, lacunae, lamella
Cranium bones partieal, squamous suture, temporal, external acoustic, frontal, corral suture, and sphenoid
facial bones ethmoid, lacarimal, nasal, zygomatic, maxilla, mental foarem, mandible, coronoid process, styloid
full body bones cranium (brain), hyoid, clavicle, vertebrate column, carpals, metacarpals, sternum, humerus, ribs, hipbones, radius, ulna, femur, patella, fibula, tarsals, metatarsals, phalanges, coccyx, sacrum, tibula, calcaneus, patella
Syndesmoid bones are bound by long fibers of connective tissue forming the interosseous ligament
suture the sutural ligament is a thin layer of dense connective tissue found in between the flat bones of the skull after growing together
Gomphosis the peg-like root of a tooth fastened to the jawbone by periodical legament
Synchondrosis many of these structures are temporary and will disappear during growth
symphysis joint is the articular surface that is separated by a thin layer of hyaline cartilage attach to a band of fibrocartilage
Synovial joints that are diarthrotic (free movement)
names of fibrous joints syndemosis, suture, gomphosis
cartilage joints synchondrosis, symphysis
synovial joints articular cartilage, joint cavity, joint capsule, synovial membrane, synovial fluid, meniscus
flexion bending the bone (action)
extension moving the bone outward
hyperextension exercise that works the lower back and (extend bone greater than normal)
Dorsiflextion backwards flexion (bending)
Plantar flexion the act of bending or the condition of being bent
abduction the movement of a limb or other part away
adduction is the movement of a body part toward the body's midline.
Rotation moving a part around the axis
circumduction moving apart so that it sends follow a circular path
supuration/pronation rotation of forearm so the palm is upward or facing anteriorly
eversion/inversion refer to movements that tilt the sole of the foot away from
protraction/retraction rotation of forarms that the palm is downward or facing posteriorly
elevation/depression raising a part (shrugging the shoulders) moving the head up and down
sprains over stretching or tearing of connective tissue
brsitis inflammation of the bursa can be caused by over use
arthritis painful inflammation and stiffness of the joint
RA autoimmune disorder chronic with flairs
OA most common type of arthritis the articular cartilage softens and distingerates as age
Lyme infection by a tick carried germs leads to inflammation of the synovial membrane
gout acute inflammation of a joint
