Chapter 5, Problem 1b
Identify the different portions (a–d) of the cutaneous membrane and the underlying layer of loose connective tissue (e) in the diagram to the right.
b. ____
Verified step by step guidance1
Step 1: Understand the layers of the cutaneous membrane. The cutaneous membrane consists of the epidermis (a), dermis (b and c), and the underlying hypodermis or subcutaneous layer (e).
Step 2: Identify the epidermis (a) as the outermost layer composed mainly of stratified squamous epithelial cells, which provides a protective barrier.
Step 3: Recognize that the dermis is divided into two parts: the papillary layer (b), which is the upper, thinner layer made of loose connective tissue, and the reticular layer (c), which is the thicker, deeper layer composed of dense irregular connective tissue.
Step 4: Note that the hypodermis (e) lies beneath the dermis and consists mainly of loose connective tissue and adipose tissue, providing insulation and cushioning.
Step 5: For part b, identify it as the papillary layer of the dermis, characterized by its loose connective tissue and proximity to the epidermis.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Layers of the Cutaneous Membrane
The cutaneous membrane, or skin, consists of two main layers: the epidermis (a) and the dermis (b and c). The epidermis is the outermost layer providing protection, while the dermis beneath contains connective tissue, blood vessels, and nerves. Understanding these layers is essential for identifying skin structures.

Epidermal Layers: Stratum Lucidum (Clear Layer)
Dermis Subdivisions: Papillary and Reticular Layers
The dermis is divided into the papillary layer (b) and the reticular layer (c). The papillary layer is the upper, thinner part with loose connective tissue and capillaries, supporting the epidermis. The reticular layer is thicker, composed of dense irregular connective tissue, providing strength and elasticity.

Hypodermis (Subcutaneous Layer)
The hypodermis (e) lies beneath the dermis and consists mainly of loose connective tissue and adipose tissue. It anchors the skin to underlying structures, provides insulation, and stores energy. Recognizing this layer helps differentiate skin from deeper tissues.
