Muskulotskeletal System

Framework that holds body together and provides movement and protection of internal organs. Includes the bones, joints and muscles

1

Bone

Constantly being resorbed and built. Bones are a balance of calcium, phosphorus, and Vitamin D.

2

4

Adult Skeleton

Contains 206 Bones. Types of bone include:
Long Bone (Femur)
Short Bone (Ankle, Toes, Wrist)
Flat Bones (Skull, Shoulder, Pelvis)
Irregular Bones (Vertebrae)
Sesamoid Bones (Kneecap)

5

Irregular bone of the face attached to the sphenoid bone

11

Sinus Cavities

Help decrease the weight of the skull, include:
