Extensive Definition
The hypodermis, also called the hypoderm,
subcutaneous tissue, or superficial fascia is the lowermost layer
of the integumentary
system in vertebrates. Types of cells
that are found in the hypodermis are fibroblasts, adipose
cells, and macrophages. It is derived
from the mesoderm,
but unlike the dermis, it
is not derived from the dermatome region of the
mesoderm. In arthropods, the hypodermis is an epidermal layer of
cells that secretes the chitinous cuticle. The term also refers to
a layer of cells lying immediately below the epidermis
of plants. This cell is also used to supervise the outer skin from
burns and other such articulates.
The hypodermis is used mainly for fat storage.
According to the eighth edition of Developmental
Biology by Scott F. Gilbert, the hypodermis of C. elegans is
derived from ectoderm.
