Pathfinders Bones and Muscles

hard shell outside of a creature

system of bones inside a creature
humans have this

support for body
marrow makes blood cells
protects organs
store minerals
levers for muscles to use to create motion

Yes. They continually regenerate, can grow and heal, and produce blood cells.

carpals, clavicle, coccyx, cranium, femur, fibula, humerus, mandible, maxillary bones, metacarpals, metatarsals, patella, pelvis, phalanges, radius, ribs, scapula, sternum, tarsals, tibia, ulna, vertebrae

place where two bones come into contact

fibrous- connected by fibrous tissue, little to no movement. skull
cartilaginous- some movement, ribs to sternum
synovial- surrounded by fluid filled synovial cavity, most movement, elbow, knee

ball and socket - hip. multi directional
ellipsoid- wrist, multi-directional, limited
saddle- fingers and thumbs, up/down and back/forth, no rotation
hinge- elbow, one direction
pivot- rotation of arm
gliding- wrists, bones glide past each other

fracture
open- bones sticks out
closed- bone inside
transverse- break is at a right angle to long axis
communited- three or more pieces
greenstick- partial break
stress- hairline crack

bones can heal themselves
doctors help by setting the bone to the proper shape and then immobilizing the area, such as a cast

depletion of minerals from bone, weakens bones, makes them easier to break
anyone can get it, but more common in older women
decrease risk by:
avoiding soft drinks, alcohol, tobacco
maintain healthy weight, low weight increases risk
lots of calcium
lots of vitamin D
exercise

make movement
internal- heart beat
external-walking

cardiac- heart muscle, branching fibers
skeletal- attached to skeleton
smooth- organs, used to breathe and move food

masseter, trapezius, deltoid, pectoralis, biceps, abdominal, quadriceps, triceps, latissimus dorsi, gluteus maximus, hamstrings, gastrocnemius, soleus

skeletal, under conscious control

unconsciously controlled
