25
5 major roles of the skeletal system
1. structure/support
2. protection
3. nutrient storage
4. create blood cells
5. facilitates movement
26
yellow marrow
storage of fatty acids
27
red marrow
creates blood cells
28
the process in which blood cells are created in the bones
hematopoiesis
29
5 main types of bones with an example
long bone (femur)
short bone (tarsals)
flat bone (cranium/sternum)
irregular bone (vertebra)
sesamoid bone (patella)
30
diaphysis
shaft, longest part, compact bone
31
epiphysis
proximal and distal end of bones "spongy bone"
32
metaphysis
growth plate (located just under the epiphysis)
33
periosteum
encases the entire bone
34
where do tendons and ligaments attach on the bone?
periosteum
35
tendons
attach muscle to bone (rectus femurs tendon)
36
ligaments
attach bone to bone (ex. anterior cruciate ligament or ACL)
37
synarthrosis
little movement and bones are attached (sutures)
38
diarthrosis
free movement, most common clinically (shoulder and hip joints)
39
amphiarthrosis
some movement (vertebrae)
40
articular capsule
encases entire joint, increasing stability
41
articular cartilage
proximal/distal end of bone, shock absorbing, decreased friction
42
synovial membrane + fluid
acts as a lubricant in the synovial membrane
43
articular disc
intracapular, increased stability
44
bursae
extracapular fluid filled sac to reduce tendon friction
