Which of the following functions is associated with skeletal muscle?
Forming the contractile component of the digestive urinary, and reproductive systems
Contracting to cause involuntary muscle movements
Pumping blood throughout the body
Shivering for heat production
The Correct Answer is D
a. Forming the contractile component of the digestive, urinary, and reproductive systems: This describes smooth muscle, not skeletal muscle.
b. Contracting to cause involuntary muscle movements: This is a characteristic of smooth and cardiac muscles. Skeletal muscle is primarily involved in voluntary movements.
c. Pumping blood throughout the body: This is the function of cardiac muscle, not skeletal muscle.
d. Shivering for heat production: Correct. Skeletal muscles generate heat through shivering, which is an involuntary contraction response to cold.

Correct Answer is A
Explanation
a. Sodium: Correct. Sodium (Na⁺) is the primary extracellular cation and plays a crucial role in maintaining osmotic pressure and fluid balance in the body.
b. Magnesium: Magnesium (Mg²⁺) is important for many cellular functions but is not a major contributor to osmotic pressure compared to sodium.
c. Calcium: Calcium (Ca²⁺) is vital for bone health and cellular processes but does not primarily influence osmotic pressure.
d. Potassium: Potassium (K⁺) is the main intracellular cation and affects cell function, but sodium has a more significant role in osmotic pressure regulation.
Correct Answer is B
Explanation
a. Destroy pathogens that enter a break in the skin: While mast cells can contribute to the defense against pathogens by releasing inflammatory mediators, their primary function is not the direct destruction of pathogens.
b. Produce histamine and leukotrienes that initiate inflammation: This is correct. Mast cells are known for their role in releasing histamine and leukotrienes, which are key mediators of the inflammatory response.
c. Cushion bony prominences: This is not a function of mast cells. Cushioning bony prominences is a role more related to adipose tissue.
d. Connect skin to muscles: This is the function of connective tissue, not mast cells.
