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 parts of the body make up the central nervous system and what are their functions?
What is the central nervous system? The central nervous system (CNS) controls most functions of the body and mind. It consists of two parts:
the brain and the spinal cord
. The brain is the center of our thoughts, the interpreter of our external environment, and the origin of control over body movement.
What three body parts make up 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 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.
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 is nervous system and its types?
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 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 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 is the most important part of the nervous system?
The brain and the spinal cord
make up the central nervous system. The nervous system is the most complex and highly organized body system. It receives information from the sensory organs via nerves, transmits the information through the spinal cord, and processes it in the brain.
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.
Why the nervous system is the most important?
Control of all bodily processes
Next to sensing and acting, the nervous system controls all processes in the body. It can stimulate tissues to produce hormones and enzymes. It stimulates the involuntary movement of muscles such as the heart and the bowels.
What are the 2 parts of 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.
Which is not a part of the central nervous system?
The other part of the nervous system is called
the peripheral nervous system (PNS)
. This is made up of all the parts of the nervous system that are not part of the CNS.
Which nervous system is responsible for movement of body?
The primary function of
the somatic nervous system
is to connect the central nervous system to the body’s muscles to control voluntary movements and reflex arcs.
What is nervous system disorder?
Brain and nervous system problems are common. These neurological disorders include multiple sclerosis,
Alzheimer’s disease, Parkinson’s disease, epilepsy, and stroke
, and can affect memory and ability to perform daily activities.
How many types of nervous system in our body?
The nervous system of vertebrate animals is divided into
two parts
called the central nervous system (CNS) and peripheral nervous system (PNS). The CNS is the largest part, and includes the brain and spinal cord.
