What are the 4 main parts of the nervous system?

The nervous system consists of the brain, spinal cord, sensory organs, and all of the nerves that connect these organs with the rest of the body.

What are the 2 types of nervous systems?

The central nervous system is made up of the brain and spinal cord. The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.

What are the 7 parts of the nervous system?

The central nervous system (defined as the brain and spinal cord) is usually considered to have seven basic parts: the spinal cord, the medulla, the pons, the cerebellum, the midbrain, the diencephalon, and the cerebral hemispheres (Figure 1.10; see also Figure 1.8).

What is the main functions of nervous system?

The nervous system helps all the parts of the body to communicate with each other. It also reacts to changes both outside and inside the body. The nervous system uses both electrical and chemical means to send and receive messages.

What are 3 main functions of the nervous system?

The nervous system has three overlapping functions based on sensory input, integration, and motor output. At a more integrative level, the primary function of the nervous system is to control and communicate information throughout the body.

What are the 3 main components of the CNS?

Central Nervous System Structure. The CNS has three main components: the brain, the spinal cord, and the neurons (or nerve cells).

How many nerves are there in the human body?

Believe it or not, there are over 7 trillion nerves in the human body. All these nerves are part of what’s known as your body’s nervous system. You can think of nerves as your body’s electrical wiring — they transmit signals between your brain, spinal cord, and the rest of your body.

What is nervous system parts and functions?

1. The Brain and Spinal Cord Are the Central Nervous System. Nerves and Sensory Organs Make Up the Peripheral Nervous System. Together, the central nervous system (CNS) and the peripheral nervous systems (PNS) transmit and process sensory information and coordinate bodily functions.

How many system do we have in our body?

The nine major organ systems in the human body are the integumentary system, the musculoskeletal system, the respiratory system, the circulatory system, the digestive system, the excretory system, the nervous system, the endocrine system, and the reproductive system.

The brain
The brain and the spinal cord are the central nervous system. The nerves that go through the whole body make up the peripheral nervous system.

What are the 2 main functions of the nervous system?

The nervous system is involved in receiving information about the environment around us (sensation) and generating responses to that information (motor responses). The nervous system can be divided into regions that are responsible for sensation (sensory functions) and for the response (motor functions).

What is the importance of nervous system?

The nervous system is made up of the brain, spinal cord and nerves. It controls much of what you think and feel and what your body does. It allows you to do things like walk, speak, swallow, breathe and learn. It also controls how the body reacts in an emergency.

What is another name for a nerve cell?

The basic unit of communication in the nervous system is the nerve cell (neuron). Each nerve cell consists of the cell body, a major branching fiber (axon) and numerous smaller branching fibers (dendrites).

Where is the nervous system located?

The central nervous system (CNS) includes the nerves in the brain and spinal cord. It is safely contained within the skull and vertebral canal of the spine. All of the other nerves in the body are part of the peripheral nervous system (PNS).
