Does the epidermis contain any blood vessels or connective tissue?
No. the dermis is where the blood vessels and connective tissue are located.
Connective tissue may or may not be avascular - it depends on the composition of the connective tissue. Avascular tissue is any tissue that does not contain blood vessels or lymphatics. Examples include epithelial tissue layers and the cornea. Elastic fibers, a form of connective tissue is avascular, but muscle is vascular.
The human skin is made up of three basic layers ; the epidermis (outer layer), the dermis(middle layer) beneath the epidermis and the subcutaneous layer beneath the dermis. The subcutaneous layers are fat cells and connective tissue that carry the blood vessels and nerves. It is located below the epidermis and the dermis, in that order, and is the third and final layer and consists primarily of loose connective tissue and lobules of fat.
Skin is differentiated into: * Epidermis * Dermis and * Hypodermis # Epidermis: It is made up of stratified squamous epithelium in which keratiocytes, melanocytes, Langerhans cells and Merkel cells are seen. # Dermis: It mostly consists of connective tissues and contains blood vessels, sebaceous glands, sweat glands, hair follicles, apocrine glands and lymphatic vessels. # Hypodermis: is made up of adipose tissue.
The epidermis can be divided into two main parts which are the epidermis and the dermis. The epidermis is composed of layers of squamous (flattened) epithelial cells which provide us with protection from scrapes and friction and burns. It is also, for the most part, dead tissue. The dermis is the tissue underneath the epidermis and is largely connective tissue which contains our sensory receptors for feeling things like touch or heat as well as…
whereas most tissue are vascular (contain blood vessels), epithelium is avascular, meaning it lacks blood vessels. epithelial cells receive their nutrients from capillaries in the underlying connective tissue. although blood vessels do not penetrate epithelial sheets, nerve endings do; that is, epithelium is innervated (supply organ with nerve).
The epidermis is the part of the skin that faces the outside or enviroment. The dermis is the layer just under the epidermis that contains hair follicles,nerves,blood and lymph vessels - the layer you get the sense of touch from. It is made of connective tissue. The function of the dermis is to be the major support structure for the epidermis. It contains the strength in its fibers and is considered to be the true…
