Step-by-step explanation:
The four main types of tissues in the human body are nervous tissue, epithelial tissue, connective tissue, and muscle tissue.
Nervous tissue allows for the transmission of signals in the form of nerve impulses and is found in the brain, spinal cord, and nerves.
Epithelial tissue lines the surfaces of the body and serves functions such as protection and filtering.
Connective tissue supports and binds other tissues and organs together.
Muscle tissue allows for movement in the body.
