25
Q

5 major roles of the skeletal system

A
  1. structure/support
  2. protection
  3. nutrient storage
  4. create blood cells
  5. facilitates movement
26
Q

yellow marrow

A

storage of fatty acids

27
Q

red marrow

A

creates blood cells

28
Q

the process in which blood cells are created in the bones

A

hematopoiesis

29
Q

5 main types of bones with an example

A

long bone (femur)
short bone (tarsals)
flat bone (cranium/sternum)
irregular bone (vertebra)
sesamoid bone (patella)

30
Q

diaphysis

A

shaft, longest part, compact bone

31
Q

epiphysis

A

proximal and distal end of bones “spongy bone”

32
Q

metaphysis

A

growth plate (located just under the epiphysis)

33
Q

periosteum

A

encases the entire bone

34
Q

where do tendons and ligaments attach on the bone?

A

periosteum

35
Q

tendons

A

attach muscle to bone (rectus femurs tendon)

36
Q

ligaments

A

attach bone to bone (ex. anterior cruciate ligament or ACL)

37
Q

synarthrosis

A

little movement and bones are attached (sutures)

38
Q

diarthrosis

A

free movement, most common clinically (shoulder and hip joints)

39
Q

amphiarthrosis

A

some movement (vertebrae)

40
Q

articular capsule

A

encases entire joint, increasing stability

41
Q

articular cartilage

A

proximal/distal end of bone, shock absorbing, decreased friction

42
Q

synovial membrane + fluid

A

acts as a lubricant in the synovial membrane

43
Q

articular disc

A

intracapular, increased stability

44
Q

bursae

A

extracapular fluid filled sac to reduce tendon friction
