What Are the Parts of the Nervous System? The nervous system is made up of
the central nervous system and the peripheral nervous system
: 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 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 are the 5 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. Together, these organs are responsible for the control of the body and communication among its parts.
What are all parts of the nervous system?
The nervous system has two main parts: 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 4 nervous systems?
- The sympathetic nervous system.
- The parasympathetic nervous system.
- The enteric nervous system.
What is nervous system with diagram?
The Central Nervous System is the integration and command center of the body. It consists of the brain, spinal cord and the retinas of the eyes. The Peripheral Nervous System consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect the central nervous system to arms, hands, legs and feet.
What are the 2 parts of the nervous system?
- 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 is the main function of 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.
How is nervous system divided?
The nervous system as a whole is divided into two subdivisions:
the central nervous system (CNS) and the peripheral nervous system (PNS)
.
What is nervous system and its function?
Your nervous system is
your body’s command center
. Originating from your brain, it controls your movements, thoughts and automatic responses to the world around you. It also controls other body systems and processes, such as digestion, breathing and sexual development (puberty).
What are the 3 functions of the central nervous system?
The CNS is comprised of the brain, cerebellum and spinal cord. Remaining neurons, and associated cells, distributed throughout the body form the PNS. The nervous system has three broad functions:
sensory input, information processing, and motor output
.
What are the four main functions of the nervous system?
- Control of body’s internal environment to maintain ‘homeostasis’ An example of this is the regulation of body temperature. …
- Programming of spinal cord reflexes. An example of this is the stretch reflex. …
- Memory and learning. …
- Voluntary control of movement.
How many types of nervous system are there?
The nervous system of vertebrates (including humans) is divided into
the central nervous system (CNS) and the peripheral nervous system (PNS)
. The (CNS) is the major division, and consists of the brain and the spinal cord.
What is the biggest part of the brain?
The forebrain is the largest and most highly developed part of the human brain: it consists primarily of
the cerebrum
(2) and the structures hidden beneath it (see “The Inner Brain”). When people see pictures of the brain it is usually the cerebrum that they notice.
What is the cause of nervous system disorders?
Some serious conditions, diseases, and injuries that can cause nervous system problems include:
Blood supply problems
(vascular disorders). Injuries (trauma), especially injuries to the head and spinal cord. Problems that are present at birth (congenital).
How our nervous system works?
The nervous system
takes in information through our senses, processes the information and triggers reactions
, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain.
