Ch 4 - Musculoskeletal System (Orthopedics) Flashcards
🩻
how are bones formed?
start as cartilage, blood vessels penetrated and bone cells start to replace the cartilage model (usually hardening from the center out)
vertebrae
smaller bones making up the spin
what are the four sections of the spine?
1) cervical: neck
2) thoracic: chest/ upper back
3) lumbar and sacral: lower back

joints
connection points between bones
flexion
bending of a joint
extention
straightening of a bone
tendons
hold muscle to bone
ligaments
hold bone to bone
cartilage
surrounds bones at the joints for smoother movement
bursae
sacks of fluid under many tendons
chrondr/o
cartilage
striations
lines (muscle fibers appear as lines under a microscope - so skeletal muscle = striated muscle)
fascia
thick membrane surrounding skeletal muscle
ton/o
tone, tension
kinesi/o (kinet/o)
movement, motion
tax/o
arrangement, order, coordination (taxonomy)
ankyl/o
stiff, bent

slow movement
dyskinesia
inability to control movement
dystaxia
poor coordination
dystonia
poor muscle tone
graphospasm
writer’s cramp
hyperkinesia
increase in muscle movement or activity
hypertonia
increased muscle tone or tightness
