What are the functions of the human nervous system?

The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.

What are the four characteristics of the nervous system?

The characteristics of the nervous system are:

• It is made up of numerous nerve cells.
• Nerve cells are excitable and respond to external stimuli.
• Nerve cells show conductivity by transmitting signals from one cell to the other.
• Transmission of signals is through neurotransmitters.
• The brain is the major organ.

What are the 3 parts of the nervous system?

• The central nervous system (CNS) is made up of the brain, cerebellum and the spinal cord.
• Nerves make up the peripheral nervous system (PNS), which works to send signals to and from the CNS, the body’s organs, muscles, and senses.

What are the special features or characteristics of the nervous system?

Nervous system cells are called neurons. They have three distinct parts, including a cell body, axon, and dendrites. These parts help them to send and receive chemical and electrical signals.

What are three major characteristics of the nervous system?

The nervous system has three broad functions: sensory input, information processing, and motor output. In the PNS, sensory receptor neurons respond to physical stimuli in our environment, like touch or temperature, and send signals that inform the CNS of the state of the body and the external environment.

What are the 3 main divisions of the nervous system?

Divisions of the Nervous System

• Cranial nervous system.
• Peripheral nervous system.
• Autonomic nervous system.
• Central nervous system.

What is human nervous system?

Human nervous system – the part of the human body that coordinates a person’s voluntary and involuntary actions and transmits signals between different parts of the body. The human nervous system consists of two main parts: the central nervous system (CNS) and the peripheral nervous system (PNS).
