Analyze the diagram labels

Using the Integumentary System Anatomy knowledge point, we identify the layers and structures of the skin:

• a represents the epidermis.
• b represents the dermis.
• c represents the hypodermis (subcutaneous layer).
• d represents a nerve fiber or deep receptor.
• e represents the arrector pili muscle.
• f represents a sebaceous gland associated with the hair follicle.
• g points to a coiled tubular structure located in the dermis.

Identify structure "g"

Using the Cutaneous Glands knowledge point, we distinguish between the different glands shown:

• The gland labeled g is a coiled, tubular gland that opens directly onto the skin surface via a duct. This is characteristic of a sweat gland (specifically an eccrine/merocrine sweat gland, or generally categorized under sweat glands).
• Let's evaluate the given multiple-choice options:

1. Apocrine sweat gland: A coiled tubular gland, usually larger and deeper, often emptying into a hair follicle.
2. Sebaceous gland: Multilobed gland associated with hair follicles (labeled f).
3. Lamellated corpuscle: A layered, onion-like sensory receptor located deep in the dermis/hypodermis (labeled near d).
4. Arrector pili muscle: Smooth muscle band (labeled e).

Comparing the options, g represents a sweat gland, specifically matching the option Apocrine sweat gland in this context.
