acetabulum
the first cervical vertebra is the
atlas
sally has high levels of blood calcium. in order to maintain homeostasis, what hormone will sally secrete to decrease this high level by putting the calcium in bone?
calcitonin
some marrow of long bones is termed "red" marrow. the function of red marrow is to
do hematopoiesis (make blood bells)
the later malleolus is part of the
fibula
the type of joint between carpal or tarsal bone in described as
gliding
what hormone stimulates changes in bone, both interstitial and appositional?
growth hormone
appositional growth deposits a new layer of bone
in lamellae which increases the width of the bone
what happens at the epiphyseal plate in long bones
interstitial growth
turning the ankle so that the plantar surface faces medially is
inversion
a person sits on his/her
ischium
a band of connective tissue that attaches a bone to a bone is a(n)
ligament

the talus bone is a tarsal that articulates with what landmarks on tibia and fibula
malleolus
the thick fibrocartliage disks found in the knees joint are called
menisci
Tendons attach
muscle to bone
what bone cell makes the bone matrix, thus builds the bone
osteoblast
a passageway (or river) connecting neighboring osteocytes in a lacunae is a
osteocanal
the bone cell that is responsible for breaking down bone so it can be reformed is the
osteoclast
what outer membrane covers the surface of a bone
periosteum
the cervical vertebrae joints are an example of ___ joints
pivot
Rotating the forearm so that the palm faces posteriorly is called
pronation
the function of synovial fluid in sacs is to
provide cushion in a bursa for connecting bones to reduce friction(east motion)
If you break the lateral bone of your forearm, you have fractured your
radius
this type of joint is biaxial allowing a wide range of movement, you thumb is one of them
saddle

trabeculae
your elbow is actually the olecranon process of what bone
ulna
what bone or landmark is part of the axial skeleton
vertebrae
the opening in each vertebrae for the spinal cord is the
vertebral foramen
osteoclast activity is increased by
vitamin D
what is true about bone remodeling and repair (wolfs law)
you will change the bone at the tendon site if you increase muscle action
getting a kiss of the check means this bone is involved:
zygomatic bone
