what is the major structural difference between epithelial tissue and connective tissue?
148354
The functions of epithelial cells are secretion, selective absorption, protection, transport, and sensing. Epithelial tissue can be found above the basement membrane. Connective tissue forms a framework and support structure for body tissues and organs. It is made of fibers, ground substance, and cells.

Connective tissues are made up of a matrix consisting of living cells and a non-living substance, called the ground substance. The ground substance is made of an organic substance (usually a protein) and an inorganic substance (usually a mineral or water). ... The matrix in connective tissues gives the tissue its density.

Which of the following is not an example of connective tissue? Explanation: Skin is composed of epithelial cells, and is therefore not an example of connective tissue. The major types of connective tissue include bone, adipose, blood, and cartilage.

Epithelial tissue is made of layers of cells that cover the surfaces of the body that come into contact with the exterior world, line internal cavities, and form glands. ... Nervous tissue allows the body to receive signals and transmit information as electric impulses from one region of the body to another.

Connective tissue has three main components: cells, fibers, and ground substance. ... Connective tissues can have various levels of vascularity. Cartilage is avascular, while dense connective tissue is poorly vascularized. Others, such as bone, are richly supplied with blood vessels.

Characteristics of Epithelial Layers Epithelial tissue is composed of cells laid out in sheets with strong cell-to-cell attachments. These protein connections hold the cells together to form a tightly connected layer that is avascular but innervated in nature.

Connective tissues come in a vast variety of forms, yet they typically have in common three characteristic components: cells, large amounts of amorphous ground substance, and protein fibers.

In epithelial tissue, cells are closely packed with little or no extracellular matrix except for the basal lamina that separates the epithelium from underlying tissue. The main functions of epithelia are protection from the environment, coverage, secretion and excretion, absorption, and filtration.

Dense connective tissue forms strong, rope-like structures such as tendons and ligaments. Tendons attach skeletal muscles to bones; ligaments connect bones to bones at joints. Ligaments are more stretchy and contain more elastic fibers than tendons.

Membranes are thin layers of epithelial tissue usually bound to an underlying layer of connective tissue. Membranes cover, protect, or separate other structures or tissues in the body. The four types of membranes are: 1) cutaneous membranes; 2) serous membranes; 3) mucous membranes; and 4) synovial membranes.

Difference Between Simple And Complex Tissue. The key difference between simple and complex tissue is, simple tissue is made up of only one type or kind of cell whereas complex tissue is made up of different type of cells. ... Example blood tissue. Below are some other differences between the two tissues.

In a simple epithelium the cells form a single layer and are all attached to the basement membrane. A stratified epithelium consists of multiple layers of cells in which only the basal layer is attached to the basement membrane.

Function of epithelial cells is to form linings or covering membranes - reflected in the arrangement of fitting closely together to form intact sheets of cells. ... The functions of connective tissue are protection, support, & binding other tissues together - reflected in matrix for strength & fibers for support.

A tissue is a group of cells with a similar structure and function working together. ... An organ is made up of different types of tissues.

Connective tissue is one of the four basic types of animal tissue, along with epithelial tissue, muscle tissue, and nervous tissue. It develops from the mesoderm. ... All connective tissue consists of three main components: fibers (elastic and collagenous fibers), ground substance and cells.
