A dermal papilla is composed of which of the following?

• A. Areolar connective tissue
• B. Stratified squamous epithelium
• C. Dense regular connective tissue
• D. Adipose tissue

Answer: (A)

Verified step by step guidance

1. Understand the structure and function of a dermal papilla: Dermal papillae are small, finger-like projections found in the dermis layer of the skin that interlock with the epidermis. They play a role in strengthening the connection between the dermis and epidermis and contain capillaries to nourish the epidermis.
2. Review the types of tissues listed in the options: Areolar connective tissue, stratified squamous epithelium, dense regular connective tissue, and adipose tissue. Each has distinct characteristics and functions in the body.
3. Recall the composition of the dermis: The dermis is primarily composed of connective tissue, including areolar connective tissue and dense irregular connective tissue. Dermal papillae specifically contain areolar connective tissue, which provides flexibility and support.
4. Eliminate incorrect options: Stratified squamous epithelium is found in the epidermis, not the dermis. Dense regular connective tissue is found in tendons and ligaments, not in dermal papillae. Adipose tissue is primarily found in the hypodermis, not the dermis.
5. Conclude that the correct answer is areolar connective tissue, as it matches the composition and function of dermal papillae within the dermis.
