Страница: 6 из 68It consists of aloosely packed, irregular meshwork of collagen fibrils that contain fine blood vessels and nerve endings.
Reticular layer is the deeper dermal layer and consists of coarse collagen bundles intertwined with elastic fibers in a gel matrix. This layer is a typical dense irregular connective tissue.
HYPODERMIS: this layer of loose vascular connective tissue is infiltrated with adipocytes and corresponds to the superficial fascia of gross anatomy. However, since it contains the deepest portions of the cutaneous glands and hairs, it is also an important part of the skin. The hypoder-mis fastens the skin to underlying muscles and other structures.

6. Cutaneous appendages
Cutaneous appendages are all derivatives of the epidermis.
Eccrine (merocrine) sweat glands are simple, coiled, tubular glands that are widely distributed over the body. Secretory portions are tightly coiled and consist of a single layer of columnar-like pyramidal cells.
Duct portions, composed of two cuboidal cell layers, are corkscrew-shaped and open onto the epidermal surface. These glands are important in thermal regulation.
Control of the eccrine glands is mainly by the innervation of cholinergic fibers.
Apocrine sweat glands are also simple, coiled, tubular glands but are much less abundant in their distribution than eccrine glands. They can be found in the axillary, ar-eolar, and anal regions.
Secretory portions of these glands are composed of a single layer of cuboidal or columnar cells.
