a-The subcutaneous layer attaches the skin to underlying bone and muscle.
b-The subcutaneous layer is a site of lipid storage.
c-The main cell types of the subcutaneous layer are fibroblasts, adipocytes, and macrophages.
d-Thesubcutaneous layer is composed of dense connective tissue with collagen and elastin fibers.
e-The subcutaneous layer can also be referred to as the hypodermis.

Answer 1

The false statement about the subcutaneous layer is that it is composed of dense connective tissue with collagen and elastin fibers; it is actually made of loose, areolar connective tissue and adipose tissue.

Step-by-step explanation:

The student asked which statement regarding the subcutaneous layer, also known as the hypodermis, is false. The false statement is: d-The subcutaneous layer is composed of dense connective tissue with collagen and elastin fibers. In fact, the hypodermis is mainly composed of well-vascularized, loose, areolar connective tissue and adipose tissue, not dense connective tissue. Functions of the hypodermis include connecting the skin to underlying bone and muscle, serving as a site of lipid storage with adipocytes (fat cells) providing energy reserves, thermal insulation, and cushioning, as well as housing important blood vessels and sensory neuron axons.
