Question

figure 5.1

using figure 5.1, match the following:

dense irregularly arranged, fibrous connective tissue.

Explanation:

Identify the labeled structures in Figure 5.1

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

• E points to the thin outer layer of the skin, which is the epidermis (Epidermal Layers).
• D bracket spans the thick middle layer of the skin, which is the dermis.
• B points to the subcutaneous fat cells (adipocytes) in the hypodermis (Hypodermis Structure, Adipose Tissue Function).
• A points to the arrector pili muscle.
• C points to a sweat gland (sudoriferous gland).

Determine the tissue composition of the labeled layers

The question asks to match "Dense irregularly arranged, fibrous connective tissue" to one of the labeled regions.

• The epidermis (E) is composed of keratinized stratified squamous epithelial tissue.
• The dermis (D) is divided into the papillary layer (areolar connective tissue) and the reticular layer, which is composed of dense irregular connective tissue.
• The hypodermis (B) is composed primarily of adipose and areolar connective tissue.

Match the tissue description to the correct label

Since the reticular layer of the dermis makes up the bulk of the dermis (D), the dermis is characterized histologically as being composed primarily of dense irregular connective tissue. Therefore, the correct label is D.

Answer:

Using Figure 5.1, match the following:
