Tissue Types
Keerthi Narasimhan
Connective Tissue
Connective tissue is the most abundant and the most widely distributed of the tissue. Connective tissues perform a variety of functions including support and protection. Loose connective tissue, fat tissue (adipose), dense connective tissue, bone, blood and lymph are all connective tissues that are found in the human body. Connective tissue comes in many different forms. Bone is more densely packed than blood because bones are the main structure and protection of the body, and therefore need to be solid and hard. Blood, on the other hand, is floating around very loosely because blood is a liquid.
Epithelial Tissue
Epithelial tissue covers the body surface and forms the lining for most internal cavities. The major function of epithelial tissue includes protection, secretion, absorption and filtration. The skin is an organ made up of epithelial tissue which protects the body from dirt, dust, bacteria and other microbes that may be harmful. The epithelial tissue types are simple squamous, simple cuboidal, simple columnar, stratified columnar, stratified cuboidal and stratified squamous. Cells can be thin, flat, cubic or elongated. The thicker epithelial tissues usually do the harder jobs, such as protection or absorption.
Muscle Tissue
The three types of muscle tissue are skeletal, smooth and cardiac. Skeletal muscle is a voluntary type of muscle tissue that is used in the contraction of skeletal parts. Smooth muscle is founds in the walls of internal organs and blood vessels. It is involuntary. The cardiac muscle is found only in the walls of the heart and is involuntary in nature. One form of muscular tissue is the smooth muscle tissue has no gaps and is tightly packed to effectively protect organs and blood vessels.
Nervous Tissue
Nerve tissue is composed of specialized cells which not only receive stimuli, but also conduct impulses to and from all parts of the body. Nerve cells AKA neurons are long and string like, for the reason of easy communication with stimuli.
Best Tissue Type
In my opinion, the best tissue type in connective. Connective tissue is very important, for that its' job is to support and protect the body and is located everywhere in the body. Connective tissue also includes two of the most important things of the body: blood and bone.
