Question

question 20

the reason the hypodermis acts as a shock absorber is that ______.

a it has no delicate nerve endings and can therefore absorb more shock
b the major part of its makeup is adipose, which serves as an effective shock absorber
c the cells that make up the hypodermis secrete a protective mucus
d it is located just below the epidermis and protects the dermis from shock

Explanation:

Analyze the hypodermis structure

Using the Hypodermis Structure knowledge point

• The hypodermis (subcutaneous layer) lies deep to the dermis.
• It consists primarily of loose connective tissue and adipose tissue.

Evaluate the shock absorption mechanism

Using the Adipose Tissue Function knowledge point

• Adipose tissue contains adipocytes storing fat.
• This fatty composition cushions organs and acts as an effective shock absorber.

Assess the given options

• Option A is incorrect because nerve endings do not determine shock absorption.
• Option B is correct because adipose tissue serves as a physical cushion.
• Option C is incorrect because the hypodermis does not secrete mucus.
• Option D is incorrect because it is located below the dermis, not directly below the epidermis.

Answer:

• (A) It has no delicate nerve endings and can therefore absorb more shock
• (B) the major part of its makeup is adipose, which serves as an effective shock absorber (Correct answer)
• (C) the cells that make up the hypodermis secrete a protective mucus
• (D) it is located just below the epidermis and protects the dermis from shock
