Which morphological adaptations of neurons make them suitable for the transmission of nerve impulse? (e.g. how does the structure of neurons dictate the function of neurons)

Identify the four types of tissue in the body, and describe the major functions of each tissue.

Epithelial tissue - layers of cells that cover the surfaces of the body (e.g. internal cavity linings, glands, surfaces exposed to outside exterior). Connective tissue - binds the cells and organs of the body together (e.g. protection, support, and integration) Muscle tissue - 3 types: skeletal, smooth, cardiac. All respond to stimulation and provide movement. Nervous tissue - transmit info and receive signals throughout body
