Hematopoiesis
|
blood cell production which occurs in the red marrow of certain bones

lipids are stored in the YELLOW MARROW of bones
|
|
Bones are composed of ____ marrow and _____ marrow
|
red and yellow

|
Red bone marrow is found in the___________________________________________________________________?
|
ribs, breastbone, shoulder blades, collarbones, hip bones, skull, spine
|
|
Long Bones
|
Longer than they are wide, the shaft of the bone widens at the ends
|
|

|
thin and flattened
|
|
what are the two flat boens
|
skull and ribs
|
|
Short bones
|
cube like, long as they are wide
|
|
What are the 5 short bones?
|
carpals, metacarpals, tarsals, metatarsals, phalanges
|
|
Irregular Bones
|
specific shape, unlike other types of boens
|
|
what are the 3 irregular bones
|
vertebrae, facial bones, hip bones
|
|
Sesamoid or round bones
|
found embedded in tendons
|
|
Sutural or Wormian bones
|
occur b/w the joints of cranial bones of the skull
|
|
what are the sesamoid/round bone?
|
patella (knee cap)
|
|
Compact Bone
|
hard outer layer of the bone
|
|
Spongy Bone
|
lies under the compact bone and contains the marrow
|
|
Ossification
|
hardening of cartilage into bone
|
|
Bone growth
|
the bone elongates at the growth plate (epiphyseal line/union) where the cells divide forming new cartilage
|
|
Growth plate AKA
|
epiphyseal line/union
|
|
Surface features of bones
|
projections, depressions, ridges or grooves that either help form joints, provide attachement for muscles/tendons, or provide passageways for blood vessels and nerves
|
|
Axial Skeleton
|
80 bones; head vertebrae and thorax
|
|
Appendicular Skeleton
|
126 bones; shoulder, hip, limbs
|
|
3 functions of the skeletal system
|
sex, age, race determination
|
|
Pelvis
|
the females pelvis is generally larger than the males bc it's designed to give birth
|
|
Two bones used to determine sex?
|
skull and pelvis
|
|
Skull
|
males are larger and heavier; they have a bony ridge above their eyes, they have low, slanted foreheads and smooth upper eye rim; they eye orbit and mandible is square shaped while females are round

|
skull
|
|
What do you use to determine soemone height?
|
examine long bones
|
|
What is the best bone to use when determining someones age?
|
pelvis: bc many changes occur at the face of the pubic symphysis and the auricular surface of the ilium over time
|
|
Ephiphyseal Union
|
layer of cartiliage that forms a distinct line in the long bones and becomes faint as bone ossifies with age
