notice the dens
makes a pivot point on
which skull pivots. It
articulates with C1 to allow
the ‘no movement

Question 10

Answer 10

when the softer nucleus
pulposus protrudes through the harder outer annulus fibrosis (fibrocartilage) because of (constant) excessive pressure

relatively flat, but may be curved, and contain a thin, spongy bone inte- rior covered by a thin veneer of compact bone.

Question 15

Irregular bones

Answer 15

do not easily fit into any of these categories.

Question 18

What is Red Marrow

Answer 18

Answer 19

Axial has 80 bones and protect the internal organs

Appendicular has 126 bones and helps with movement.

Question 20

Paranasal
