Tissues of the Human Body
What's What Concerning the Types of Tissues in the Body
The Varying Types of Tissues
The human body consists of four main types of tissues, including epithelial, connective, muscle, and nervous tissue. These types of tissues have varying functions throughout the body and helps support the body in many ways. Through this pamphlet, you should be able to distinguish between the four tissues based on description and image.
Epithelial Tissue
This type of tissue is found, outside and inside the body's surface. The cells that make up this tissue are so closely packed together that they form a protective barrier. This aids the tissue in its duty to protect the body. Also, by having differing shapes and thickness of cells, the epithelial tissue is able to help in the processes of secretion, absorption, and filtration.
Connective Tissue
This type of tissue consists of five types, including bone, cartilage, dense, loose, and blood connective tissue. All five of these connective tissues are arranged by most ridged to less ridged. This gives a look into their forms and their functions, such as blood being less ridged in order to transport substances quickly. Bone is the most ridged because it supports and protects the body, while cartilage assists in movement. Loose connective tissue protects internal organs and dense connective tissue is far more tolerant of pressure and stretching so it assists in movement, and wear and tear.
Muscle Tissue
This type of tissue is separated into three types of skeletal, smooth, and cardiac. Due to muscle tissue being soft, it has the ability to easily contract which allows it to assist primarily in movement of all types. Skeletal is found in larger muscles which supports the movement of the body. Smooth muscle tissue is so sleek that it can transport blood, food, and waste quickly. Cardiac muscle tissue allows the synchronized contractions of the heart which involves a great deal of movement.
Nervous Tissue: Do You Have the Nerve?
This type of tissue is responsible for transmitting sensory information throughout the whole body and is found in the brain, spinal cord, and nerves. The reasoning behind the nervous tissue's functioning of processing stimuli and producing a response is all due its composition. Neurons make up the nervous system and have appendages called dendrites that come out of the receiving end of the cells. These long tendrils pick up incoming information to be processed and sent through the axon, the transmitting side of the cell, to produce a response. This tissue is the best at this job because dendrites are quite long and can reach through the entire body. By having covered most areas of the body, this tissue can create a reaction to situations promptly inside and outside. Also, this tissue type is best for its locations of the nerves, brain, and spinal cord because of its connections through the body, that way information can be quickly sent to the brain to be processed.
