Tissue
Anatomy & Physiology
Introduction to Tissue
Tissue can be classified into four main types. These types are epithelial, muscle, nervous, and connective tissues. Each tissue type has a different function and place in the body where it can protect, enable movement, or create impulses.
Epithelial Tissue
The form of Epithelial tissue is found in the first slide image shown below. Epithelial tissue comes in the forms of flat, columnar, or cuboidal. In the second image shown, the different classifications of epithelial tissue are illustrated to display what the different types of epithelial tissue look like. Epithelial tissue makes for great protection and can be found as the lining of organs and skin. Epithelial tissue is the best type of tissue for its function because of the way it is able to exist as different forms, sizes, and shapes which allows it to cater to every need it fulfills.

Connective Tissue
Connective tissue exists in many different different parts of the body including muscles, cartilage, and the connective system. Connective tissue also fills out any spaces inside of our bodies. Two forms connective tissue can take is shown in the first picture where the tissue appears as circular shapes and as stringy shapes. This form of tissue is useful to the places it exists in because of its ability to provide cohesion to areas that it supports.

Muscular Tissue
Muscular tissue, as show below, is long, stalky, and bundled which creates for a very strong type of tissue. Skeletal muscular tissue allows us to move and can come in voluntary forms and involuntary forms. For example, cardiac muscle tissue is involuntary as it helps in beating the heart. Muscular tissue's form allows for its function to be carried out through its stretchy and strong structure. Any other tissue would not be able to carry out the functions that muscle tissues do because muscle tissue allows us to move and strengthen our bodies in ways other tissues can not.

Nervous Tissue
Nervous tissue is found in the nervous system and can send signals throughout the body, the spinal cord, and the brain. Nervous tissue is structured in an effective way that helps conduct impulses and stimuli responses. As demonstrated in the second photo, this tissue type is in a complex yet efficient form so that all signals can be sent out smoothly and quickly. This type of tissue is specifically formed to send these important signals throughout our bodies and are very elaborately formed, including nuclei and receptors, for the task they carry out.
