  1. Production of eythrocytes

  2. Storage of minerals

  3. Production of body heat

  4. Locomotion

Show answer
Correct Option: C
Explanation:

  • The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them.
  •  The skeleton serves six major functions: support, movement, protection, production of blood cells, storage of minerals and endocrine regulation. Hence, Production of body heat is not a function of the skeletal system.
 So, the correct answer is 'Production of body heat

Show answer
Correct Option: C
Explanation:

The water and electrolyte content of skeletal muscle was an average of 78.8 gm. of water, 4.96 milliequivalent (meq.) of sodium, 8.32 meq. of potassium, 4.04 meq. of chloride, 0.445 meq. of magnesium, and 3.88 meq. of phosphorus per 100 gm. of wet tissue or muscle. Hence, the percentage of water content in skeletal muscle can vary from 75-78%.

Explanation:

A suture is a type of fibrous joint, which only occurs in the skull. These joints are synarthroses. One parietal bone is located on each side of the skull just behind the frontal bone. The temporal bones are situated at the sides and base of the skull, and lateral to the temporal lobes of the cerebrum.
