What Are the Characteristics of Nervous Tissue?
Nervous tissue is made up of two types of cells. These include neurons and supportive cells. The neurons carry electrical and chemical signals throughout the human body while the supportive cells provide nutrition to the neurons.
Nervous tissue falls into two different cell categories as well. The central nervous system is responsible for integrating information and includes the brain and the spinal cord. The peripheral nervous system brings information into and out of the central nervous system and transmits signals throughout the body.
Neurons and supportive cells are found in both the central and the peripheral nervous systems. Neurons form a network for communication throughout the body. They conduct signals from one part of the body to another to think, move and function.
Communication through the nervous tissue involves three different processes: sensory input, the integration of the sensory input and the action. All three of these processes must occur for humans to function and move properly. These processes occur through both sensory input and motor output. The sensory and motor nervous tissues each perform different actions. Sensory nervous tissues integrate sensory stimuli while the motor nervous tissue performs motor activities such as walking, talking and running. All together the nervous tissue allows humans to function properly by communicating signals between cells.
