Introduction to the Skeletal System

Made up of a layer of spongy bone between two thin layers of compact bone. Thin. (Ex. skull and ribs)

• long

• short

• flat

• irregular

• sesamoid

Bones that are approximately equal in length, width, and thickness. (Ex. carpals)

• long

• short

• flat

• irregular

• sesamoid
