Question

Which of the following is not a function of the skeletal system?
A. Production of erythrocytes.
B. Storage of minerals.
C. Production of body heat.
D. Locomotion.

Answer 1

Hint: The skeletal system includes all of the bones and joints in the body.
 A bone is a rigid organ that is a part of the vertebrate skeleton in animals.
Bones protect the various organs of the body which produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility.

Complete answer:
Skeletal system consists of bones and a few cartilages. This system has a role in movement.
Bone and Cartilage are specialized connective tissues. In human beings this system is made up of 206 bones and a few cartilages.
It is grouped into two principal divisions
1. Axial skeleton
2. Appendicular Skeleton.

Axial consists of 80 bones distributed along the main axis of the body which include the skull, vertebral column, sternum, and ribs.

The bones of limbs along with their girdles constitute the appendicular skeleton.
Each limb is made of 30 bones.
The bones of the hand are humerus, radius and ulna, carpals, metacarpals and phalanges.

The skeleton serves six major functions:
1. Support
2. Movement
3. Protection
4. Production of blood cells
5. Storage of minerals
6. Endocrine regulation.
Hence, production of heat is not a function of the skeletal system.

Hence, The correct answer is option (C).

Note: Joints are essential for all types of movement in the body. They are points of contact between bones or between bones and cartilages.
Joints have been classified into three major structural forms:
1. Fibrous.
2. Cartilaginous.
3. Synovial.
Fibrous joints: Fibrous joints are joints connected by fibrous tissue, consisting mainly of collagen.
Cartilaginous joints: Cartilaginous joints are connected entirely by cartilage.
Synovial joints: Synovial joints allow for smooth movements between the adjacent bones.
