Multiple Choice

Which of the following best describes a difference between the cuticle and the eponychium in the integumentary system?

The cuticle is a type of hair follicle, while the eponychium is a sebaceous gland.

The cuticle is found only on toenails, while the eponychium is found only on fingernails.

The cuticle is a layer of dead skin cells that overlaps the nail plate, while the eponychium is a living tissue at the base of the nail.

The cuticle is responsible for nail growth, while the eponychium produces sweat.

Verified step by step guidance

Step 1: Begin by identifying the anatomical structures mentioned in the question: the cuticle and the eponychium. Both are part of the integumentary system and are associated with the nails.

Step 2: Understand the cuticle's role and composition. The cuticle is a layer of dead skin cells that overlaps the nail plate, providing protection against infections and external damage.

Step 3: Examine the eponychium's role and composition. The eponychium is a living tissue located at the base of the nail, near the nail matrix, and it helps seal the area to prevent pathogens from entering.

Step 4: Compare the cuticle and eponychium based on their structure and function. The cuticle is non-living (dead skin cells), while the eponychium is living tissue. This distinction is key to understanding their differences.

Step 5: Eliminate incorrect options by analyzing their descriptions. For example, the cuticle is not a hair follicle, nor is it responsible for nail growth. Similarly, the eponychium does not produce sweat or exist only on fingernails. The correct answer aligns with the anatomical and functional differences described in steps 2 and 3.
