Question

which of the following statements is true of sudoriferous glands? select the correct response: they consist of little sacs with ducts that open into the hair follicles. they consist of a secretory coil and a tube - like sweat duct that ends at the skin’s surface to form the sweat pore. they secrete a fatty or oily substance that lubricates the skin and preserves the hair’s softness. their activity is significantly reduced by heat, exercise, emotions, and certain drugs.

Explanation:

To determine the correct statement about sudoriferous (sweat) glands, we analyze each option:

1. The first option's description (little sacs with ducts opening into hair follicles) matches apocrine sweat glands, but eccrine (most common) open to skin surface. However, the second option says "They consist of a secretory coil and a tube - like sweat duct that ends at the skin’s surface to form the sweat pore." This is the structure of eccrine sweat glands, which are a type of sudoriferous gland.
2. The third option describes sebaceous glands (secrete oily substance for lubrication), not sudoriferous.
3. The fourth option is incorrect as heat, exercise, etc., increase sweat gland activity, not reduce it.

Answer:

They consist of a secretory coil and a tube - like sweat duct that ends at the skin’s surface to form the sweat pore.
