The hypodermis is the deepest section of the skin.
The hypodermis is the thickest in the buttocks, palms of the hands, and soles of the feet.
As we age, the hypodermis begins to atrophy, contributing to the thinning of aging skin.

The hypodermis is subcutaneous connective tissue, equivalent to the superficial fascia in gross anatomical terms.
At low magnification, the epidermis presents as a basophilic layer of cells, while the dermis is dense collagenous connective tissue and the hypodermis is mostly fat cells.
The hypodermis is similar to that in thick skin with its numerous fat cells, vasculature and nerve.

Hypodermis is formed by a main body syncytium, hyp7, and other hypodermal cells in the head and the tail, numbered from hyp 1 through hyp 11 (also hyp13 in male).
In the embryo, the hypodermis is a monolayer of 78 cells which secrete the cuticle (Sulston et al, 1983).
Note that, in areas where hypodermis becomes a thin layer around the circumference of the body due to impingement of muscle or pharyngeal tissue (refer to SW315lbop image seen below), hypodermal GFP concentration becomes significantly lower giving the hypodermis a (false) striped appearance.

Although the hypodermis is usually not thought of as part of the skin or integumentary system, it shares some of the skins functions and will be discussed in this chapter.
The hypodermis is also and insulator: Since fat is a poor conductor of heat, it helps prevent heat loss from the body.
It tends to accumulate in the stratum corneum of the epidermis and in fat tissue of the hypodermis.

 Exercise14 Skin
It's in or near the hypodermis that most of the accessory structures (see below) are seen, although as epithelial structures and epidermal derivatives, they're separated from the dermis and hypodermis proper by a basement membrane.
The hypodermis is usually much more heavily infiltrated with fat than the dermis, and there can be very large fat depots in it in some species, especially when they're well-fed. If you've ever seen a skinned pig carcass, you're looking at about 4" of hypodermis after the dermis and epidermis have been removed.
the deep region of the gland is surrounded by hypodermis, and the duct worms its way upwards, towards the surface, eventually leading the secretion to the outside.

 Blue Histology - Integumentary System
The hypodermis is the lightest layer visible and consists mainly of adipose tissue.
The epidermis is a keratinised stratified squamous epithelium.
The red and yellow hues of the skin are due to haemoglobin in the red blood cells, which pass through the capillaries beneath the epidermis, and carotene, which accumulates in fat cells found in the dermis and hypodermis.

The walls of the one or two layers of the hypodermis were brightly fluorescent, except at the points where Casparian bands would be formed in the radial walls of the outermost hypodermal layer.
Note that all layers of the hypodermis fluoresce although the innermost, nonexodermal layers (with anchor cells) are brighter than the exodermis.

 MORPHOLOGY
Body wall: The body wall is composed of the cuticle which may be considered to be an exoskeleton; underneath the cuticle is the hypodermis and the muscular layer composed of a single layer of elongate spindle-shaped muscles.
Hypodermis: The hypodermis is a thin layer of tissue immediately underneath the cuticle.
That the hypodermis is an active layer of the body wall is evidenced by the fact that a new cuticle must be formed between each juvenile stage, usually a total of 4 times, since there are usually 5 stages in the life cycle.

 The Integument – Skin Structure and Function
The hypodermis is a loose connective tissue containing varying amounts of adipose that underlies and supports the skin; it is the superficial fascia that covers the entire body.
Arteries and veins run through the hypodermis and branch upward to form plexuses of anastomosing vessels.  The cutaneous plexus resides at the junction of the hypodermis and dermis, and the papillary plexus resides just beneath the epidermis.
THE HYPODERMIS: The hypodermis is composed of loose connective tissue with large numbers of adipose cells.

 Integument
Skin, one of the largest organs in the body (16% by weight), is composed of an epithelium, the epidermis, and an underlying connective tissue, the dermis.
Internal to the dermis is areolar connective tissue called the hypodermis (subcutaneous connective tissue).
The hypodermis consist of adipose tissue beneath the dermis.

 Sarcomere assembly in C. elegans muscle
Fibrous organelle (FO's) complexes in the hypodermis, which are similar to hemi-desmosomes, then complete the mechanical linkage to the cuticular exoskeleton (Francis and Waterston, 1991).
Patterning of the muscle to hypodermis linkage may involve the hypodermal transmembrane protein myotactin at the hypodermal/muscle interface (Hresko et al., 1999).
We raise this idea because the muscle and hypodermis are clearly interacting in important ways at this stage of development, and it is intriguing that the spacing between actin cables and newly formed dense bodies is of the same order of magnitude.

Unc phenotype varies from complete paralysis to moderately impaired movement.The hypodermis is a single layer of epithelial cells that encloses the animal and is responsible for secretion of the protective cuticle.
One candidate tissue for producing an hbl-1-dependent signal is the syncytial hypodermis (termed hyp7) that surrounds the seam, abuts the VPCs, and is a major contributor to cuticle synthesis.
During the L1 stage, HBL-1/GFP expression is observed in the hypodermal syncitial cells (e.g., hyp7), in the ventral hypodermal cells (P cells), and weakly in the lateral hypodermal seam cells (H, V, and T cells).

We study the genetics of movements in the embryonic epidermis, or hypodermis, of the nematode, C.
The hypodermis is very simple, and we can visualize cell movements within it at the level of single cells.
We have isolated mutants that are defective in two movements that occur in specific regions of the hypodermis: a movement known as convergent extension in dorsal cells, and epiboly, or spreading of the hypodermis, mediated by the ventral cells.
