In the Hypodermis of a human, vertical tethers of dense connective tissue extend upward into the dermis to help anchor the hypodermis with the dermis, while in a mouse the hypodermis consists of one more layer known as "brown fat". Additionally, the mouse's feet are always on ground at ...
Figure 1. Layers of Skin.The skin is composed of two main layers: the epidermis, made of closely packed epithelial cells, and the dermis, made of dense, irregular connective tissue that houses blood vessels, hair follicles, sweat glands, and other structures. Beneath the dermis lies the hypo...
hypodermis Thesaurus Medical Encyclopedia Wikipedia hy·po·der·mis (hī′pə-dûr′mĭs)alsohy·po·derm(hī′pə-dûrm′) n. 1.An epidermal layer of cells that secretes an overlying chitinous cuticle, as in arthropods. 2.BotanyA layer of cells lying immediately below the epidermis...
The types of tissues the hypodermis consists of can give insight into its primary functions. It consists primarily of connective tissues made of collagen proteins and elastin, which are both vital to the function of the hypodermis and a layer of fat called adipose. The cellular and tissue compos...
The skin is made of three components: epidermis, dermis and hypodermis. The epidermis consists of four layers and completely regenerates itself in a 30-day cycle known as skin turnover time. The dermis is the main component of the skin and consists of collagen and elastin, which maintain the...
The cuticle also consists of weakly acidic mucopolysaccharides. Hypodermis and muscles contain lipids and glycogen. In addition, hypodermis also consists of acidic mucopolysaccharides. The functional significance of these components has been fully discussed. 展开 ...
Another C. elegans protein, HRG-2, facilitates heme import and utilization in the hypodermis. HRG-2 is a predicted 32 kDa single-pass type I transmembrane protein and localizes to both the apical plasma membrane and the endoplasmic reticulum [167]. It is thought to function as a heme ...
(1)In animals, a solid formation on the surface of cells of epithelial tissue. In invertebrates, a derivative of cells of the single-layered integumental epithelium, or hypodermis. The functions of the cuticle are chiefly protective and supportive. In worms and arthropods, it forms a tough bod...
Accessory structures of the skin include hair, nails, sweat glands, and sebaceous glands. These structures embryologically originate from the epidermis and can extend down through the dermis into the hypodermis. Hair Hair is a keratinous filament growing out of the epidermis. It is primarily made...
A major component of the hypodermis is a type of specialized connective tissue called adipose tissue that stores excess energy as fat. Adipose tissue consists primarily of cells called adipocytes that are capable of storing fat droplets. Adipocytes swell when fat is being stored and shrink when fat...
