What attaches epithelial tissue to connective tissue?
Areolar connective tissue holds organs in place and attaches epithelial tissue to other underlying tissues. It also serves as a reservoir of water and salts for surrounding tissues. Almost all cells obtain their nutrients from and release their wastes into areolar connective tissue.
What is the name of the structure that attaches epithelial cells to underlying connective tissue quizlet?
Basement Membrane: A specialized type of extracellular material secreted by epithelial an connective tissues cells. Like Scotch tape, basement membrane helps attach epithelial cells to the underlying tissues.
What is the name of the structure that anchors all epithelial tissue to the underlying connective tissue?
The basal lamina helps to attach and anchor the cells to the underlying connective tissue. Proteins (integrins and proteglycans) in the cell membranes attach to proteins in the basal lamina, which in turn is linked to the extracellular matrix of connective tissue.
Is to attaches epithelium to deeper connective tissue?

What is connective tissue structure?
Connective tissue has three main components: cells, fibers, and ground substance. Together the ground substance and fibers make up the extracellular matrix. Cartilage is avascular, while dense connective tissue is poorly vascularized. Others, such as bone, are richly supplied with blood vessels.
What attaches epithelial cells to the basal lamina?
If the epithelial layer rests on underlying mesenchyme, a layer of collagen fibrils connects the basal lamina to the underlying tissue, sometimes with specialised anchoring collagen fibrils. The strength of this connection is important for development and growth.
What is the name of the epithelial cell surface that faces the outside of an organ quizlet?
The apical surface is the side of the cell that faces the lumen or body cavity, and the basal surface is the side of the cell that faces the underlying connective tissue.
What is the structure of epithelial tissue?
Structure. Epithelial tissue is scutoid shaped, tightly packed and forms a continuous sheet. It has almost no intercellular spaces. All epithelia is usually separated from underlying tissues by an extracellular fibrous basement membrane.
What are the structural differences between epithelial and connective tissues?
The main difference between epithelial and connective tissue is that epithelial tissue lines the cavity and the surfaces of organs and blood vessels throughout the animal body whereas connective tissue supports, connects and separates different types of tissues and organs in the body.
What is the columnar epithelium?
The columnar epithelium is composed of epithelial cells that are column-shaped. The cell comprising the columnar epithelium is taller than it is wide. Its height is approximately four times its width. The nucleus in each cell is elongated and often found near the base.
What is the structure of the epithelial tissue?
What type of cells are in connective tissue?
The common cell types in connective tissue include: fibroblasts, mast cells, plasma cells, macrophages, adipocytes, and leukocytes. Slide 72 Tendon. Fibroblasts are the most common cell type of connective tissue. They produce both fibers and amorphous ground substance.
How is the epithelial tissue attached to the body?
One surface of the epithelial tissue is exposed to either the external environment or the body fluid. The other surface is attached to tissue by a membrane, which consists of fibres and polysaccharides secreted by epithelial cells. There is little intercellular material present between cells.
Is there intercellular material in the epithelium?
There is little intercellular material present between cells. There are specialised junctions present between the cells of the epithelium, that link individual cells. Epithelial cells form membranes. The epithelial membrane consists of a layer of epithelial tissue and has underlying connective tissue.
How are epithelial cells attached to the basement membrane?
All epithelial cells are attached on their basal surface to a basement membrane. The basement membrane provides some mechanical support as it tethers together a sheet of epithelial cells. It also supports the growth and survival of the epithelia as it controls the access of epithelia to nutrients, ions, proteins and oxygen.
What are the three types of connective tissue?
Epithelial tissue consists of three types of cells – squamous, cuboidal and columnar. Cells in connective tissue are immersed in an indefinite matrix in addition to cartilaginous, collagen, elastic or fatty tissues.
