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 3 main parts of the central nervous system?
Share on Pinterest The CNS is
the brain and spinal cord
. The CNS consists of the brain and spinal cord. The brain is protected by the skull (the cranial cavity) and the spinal cord travels from the back of the brain, down the center of the spine, stopping in the lumbar region of the lower back.
What are the main functions of the central nervous system?
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 are the 3 components of our central nervous system and what are their functions?
The nervous system has three main functions:
sensory input, integration of data and motor output
. Sensory input is when the body gathers information or data, by way of neurons, glia and synapses.
What are the 3 main functions of the nervous system quizlet?
- sensory input. when sensory receptors monitor changes that occur both inside and outside of the body.
- integration. when sensory information is interpreted and the appropriate response is taken.
- motor output. response that is performed by effectors- muscles or glands.
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 four major components of the central nervous system?
- The central nervous system consists of the brain and spinal cord.
- The brain plays a central role in the control of most bodily functions, including awareness, movements, sensations, thoughts, speech, and memory.
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.
Which organ is part of our 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 diseases affect the central nervous system?
- Alzheimer’s disease. Alzheimer’s disease affects brain function, memory and behaviour. …
- Bell’s palsy. …
- Cerebral palsy. …
- Epilepsy. …
- Motor neurone disease (MND) …
- Multiple sclerosis (MS) …
- Neurofibromatosis. …
- Parkinson’s disease.
What are the two main components in the human nervous system?
- 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 is an example of the central nervous system?
The central nervous system consists of
the brain, the brainstem, and the spinal cord
. The peripheral nervous system includes the cranial nerves, the spinal nerves, the sympathetic nervous system, and the parasympathetic nervous system. … The spinal cord is continuous with the brain and lies caudally to it.
What is the structure and function of the central nervous system?
The central nervous system CNS is
responsible for integrating sensory information and responding accordingly
. It consists of two main components: The spinal cord serves as a conduit for signals between the brain and the rest of the body. It also controls simple musculoskeletal reflexes without input from the brain.
What is the main function of our nervous system quizlet?
The primary function of the nervous system is
to collect a multitude of sensory information; process, interpret, and integrate that information; and initiate appropriate responses throughout the body
.
Can you move without your nervous system?
Despite requiring little conscious thought, the muscles you control when you move are known as
voluntary muscles
, since you can control them when you think about moving.
What are the two major functions of the nervous system?
First, the basic functions of the nervous system are
sensation, integration, and response
. Secondly, control of the body can be somatic or autonomic—divisions that are largely defined by the structures that are involved in the response.
