Skeletal Anatomy

Question 1

what are the 5 functions of the skeleton

Answer 1

1. protect vital organs
   2.provide rigidity and shape to the body
2. blood formation in the bone marrow
3. stores minerals (Ca, P, Mg)
4. levers of locomotion (attachment for muscles and tendons)

Question 2

an example of how the skeleton performs each function (protection)

Answer 2

brain- skull bones
heart and lungs - rib bones

Question 3

an example of how the skeleton performs each function (rigidity and shape)

Answer 3

gives the body form
-conformation/ posture

Question 4

an example of how the skeleton performs each function (blood formation)

Answer 4

bone marrow contains stem cells for blood cell production
(rbc, wbc, platelets)

Question 5

an example of how the skeleton performs each function (mineral storage)

Answer 5

deposits and withdraws Ca, P, Mg as needed to maintain homeostasis

Question 6

an example of how the skeleton performs each function (levers of locomotion)

Answer 6

movement caused by muscles and tendons acting on the levers (bones)
