Functions of Skeletal System

Question 1

Answer 1

Support, Storage, Blood Cell Protection, Protection, and Movement

Question 2

Define SUPPORT

Answer 2

Provides structural support for the entire body

Question 5

Define PROTECTION

Answer 5

Ribs protect the heart and longs, the skull protects the brain, vertebrae protects the spinal cord, and the pelvis protects the digestive and reproductive organs

Define MOVEMENT

Answer 6

Bones allow for the movement of everything from a fingertip to the position of the entire body

Define Condyle (specific processes)

Answer 11

A smooth and rounded articular process

Question 12

Define TROCHLEA (specific processes)

Answer 12
