C Correct answer
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

B Correct answer
Explanation

Skeletal muscle represents the majority of muscle tissue. It is the type of muscle, that powers movement of the skeleton. Their composition is 75-80 percent water, 15-20 percent proteins, 1 percent glycogen, 1 percent lipids and 1 percent mineral salts.

C Correct answer
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%.

Which one of the following is the correct description of a certain part of a normal human skeleton?

  1. Parietal bone and the temporal bone and the skull are joined by fibrous joint.

  2. First vertebrae is axis, which articulates with the occipital condyles.

  3. The 9th and 10th pairs of ribs are called the floating ribs.

  4. Glenoid cavity is a depression to which the thigh bone articulates.

A Correct answer
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.

Which of the following is not a function of the skeleton system?

  1. Production of erythrocytes

  2. Storage of minerals

  3. Production of body heat

  4. Locomotion
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Skeletal system is the articulation bones to give perfect shape to the body. They help in locomotion by attaching with muscles. 

Bones are made up of minerals like Ca++ and po4-. So they act as store house of minerals. 
Bones have bone marrow which contain stem cells. Stem cells are the precursors of blood form cells like RBC, WBC and platelets,
Skeletal system doesn't play any role in production of heat. Heat production is regulated by metabolic processes. 
So the correct option is C.
