large opening at base of skull

tree bones that connect to the frontal bone

parietal bone, nasal bone, sephenoid bone

three articulations of the occipital bone

parietal bone, temporal bone(mastoid process), speniod, cervical vertebrae

differences of femur and humerus in head

humerus-neck more connected to rest of bone

femur- more of a distinction, distinct head that separates from the rest

is it easy to dislocate the shoulder joint? why?

yes, because there is a lot of extra space that would allow for the joint to tear, connection is not stable

a very shallow socket-wall-like socket

is it hard to dislocate the femur?

yes, because the femur has a surrounding connection to the hip joint

deeper socket

varying in muscle markings on the humerus

based on if someone is right handed

can cause right humerus muscles to be more deveoped

how to vertebral bodies differ

size, thickness of the body

how do spine processes differ

lengths and the amount of them in each vertebra

lumbar is very thick

cervical vertebra

foramen transversarium

shortish, bifolded spinous process

lumbar vertebra

thick spinous process that points back

thoracic vertebra

spinous process long, thick, pointed down

hand versus foot function

hand: thumb separated from the rest of the fingers

feet: big toe also separated- but less than hands

reflects hand’s ability to grab things easier than the feet

chimp feet and hands

have more function in feet

can use both for grabbing things

more difficult to see differences in hand and feet
