Does epithelial connective tissue supported and surround nerve cells and blood vessels?
No, loose connective tissue does
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).
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 serous membrane contains the epithelial layer and the connective tissue layer. The epithelial layer produces cells that produce lubricating serious fluid. The Connective tissue later houses blood vessels and nerves and serves as the "binding layer" for the serous membrane to adhere to organs and other structures in the body.
Connective tissues are based on fibrous proteins, and include bones, cartilage, tendons, ligaments, and adipose tissue (stores fat). Blood and lymph are generally classified as "fluid connective tissue" although they do not have a fixed structure and are normally constrained by epithelial cells, such as those lining the blood vessels.
The heart is a muscle, and as such has multiple tissues. The main tissue is cardiac muscle cells. These are striated, branched muscle cells held together with intercalated discs. Connective tissue forms a sac around the heart, and epithelial tissue forms blood vessels within the heart. Therefore, the heart contains all four types of tissue. It is mostly muscle tissue. Connective tissue forms a protective sac and holds the heart together, epithelial tissue forms the…
Areolar tissue is another name for loose connective tissue. It is a very common type of connective tissue that supports many structures which are normally under some pressure and low friction. It usually supports epithelial tissue, forms a layer around small blood and lymphatic vessels, and fills the spaces between muscle and nerve fibers. It is found in the papillary layer of the dermis, in the hypodermis, in the linings of the peritoneal and pleural…
Epithelial tissue covers the whole surface of the body and lines the inside of tube and hollow organs. It is made up of cells closely packed and ranged in one or more layers. It provide protections, regulates exchange, transport, secrete, the cells touch, act as barrier, ex: lungs, intestine, kidney, exocrine gland, skin, trachea, lining blood vessel. Epithelial tissues are tightly packed sheets of cells. They to protect the body (ie. you skin), absorb nutrients…
Purple discoloration to the dermis generally means blood has escaped from the blood vessels and is in the epithelial and connective tissues (commonly caused bruising). At first glance, I would be worried this is purpura hemorrhagica, a potentially nasty vascular condition that would need medical attention promptly.
