Shoulder and arm are called what kind of joint gliding joint
Ganglion cyst is filled with what fluid
CTS Carpal tunnel syndrome develops on front of wirst due to inflammation and swelling of tendon sheaths
Stenosing tenosynovitis is inflammation of the synovial sheaths on the back of the wrist tht causes pressure to develope under the retinaculum
Phalanges are fingers 14 bones in finger and thumb
carpals connect wrist to metacarpals 8 bones
metacarpals bones proximal to phalanges, middle
OA Osteoarthritis, wear and tear
RA Rheumatoid arthritis destruction of joints
JRA juvenile rheumatoid arthritis in children usually outgrows children under 17
Dupuytren contracture thickening and shortening of fibrous bands in the palm of the hand

arthroplasty complete replacement of a damaged finger joint
reattachment amputated fingers is performed
functions of pelvic griddle supports axial skeletontransmit weight to lower limbs attaches lower limbs protects organs

os coax, hip bone, consists of 3 bones ilium, ischium, and pubis
cup shaped cavity of the hip acetabulum
Thigh bone Femur
SI (sacroiliac) joint strain causes lower back pain

Four componets of skeletal system bones, cartilage, tendons, ligaments
components of the skeletal system provide what support, protection, movement, blood formation, mineral storage and balance, detoxification
Bone growth factors genes, nutrition, exercise, mineral depositoin, mineral resporption, vitamins, hormones
Healing process of fractures blood vessels provide blood and bleed into fracture site, osteoblasts for callus, cancellous replaces the callus, osteoblasts produce bone which fuses bone segments
