What is peripheral nervous system describe?
The peripheral nervous system consists of the nerves that branch out from the brain and spinal cord. These nerves form the communication network between the CNS and the body parts. The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system.
What is the peripheral nervous system and its parts?
The peripheral nervous system is divided into two main parts: Autonomic nervous system (ANS): Controls involuntary bodily functions and regulates glands. Somatic nervous system (SNS): Controls muscle movement and relays information from ears, eyes and skin to the central nervous system.
What’s the main function of the peripheral nervous system?
The PNS has three basic functions: (1) conveying motor commands to all voluntary striated muscles in the body; (2) carrying sensory information about the external world and the body to the brain and spinal cord (except visual information: the optic nerves, which convey information from the retina to the brain, are in …
What are the 3 parts of the peripheral nervous system?
The peripheral nervous system is divided into the somatic nervous system and the autonomic nervous system. In the somatic nervous system, the cranial nerves are part of the PNS with the exception of the optic nerve (cranial nerve II), along with the retina.
What are peripheral nerves examples?
The peripheral nervous system includes the cranial nerves, the spinal nerves, the sympathetic nervous system, and the parasympathetic nervous system.
What is peripheral nervous system Class 10?
The peripheral nervous system includes all the nerves in the body that lie outside of the spinal cord and the brain. These nerves carry information to and from the central nervous system to provide complex body functions. Sensory cells are involved in taking information from the periphery to the central nervous system.
What are the four functions of the peripheral nervous system?
The 4 main functions of the nervous system are: Reception of general sensory information (touch, pressure, temperature, pain, vibration) Receiving and perceiving special sensations (taste, smell, vision, sounds) Integration of sensory information from different parts of the body and processing them.
What is an example of the peripheral nervous system?
Examples of the Peripheral Nervous System Response When a bright light is suddenly turned on, sensory receptors in the eye communicate this to the CNS. The PNS mediates the response to this stimulus. The pupils contract and the external eye muscles squint.
What is the peripheral nervous system made up of?
nerves
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 is peripheral nervous system Class 11?
The nervous system is the controlling system of the body and is composed of nerve cells and organs. The peripheral nervous system comprises the network of nerves connected to the brain and the spinal cord. The nerves fibres are of two types – afferent fibres and efferent fibres.
What is peripheral nervous system Class 11 psychology?
The Peripheral Nervous System The PNS is composed of all the neurons and nerve fibers that connect the CNS to the rest of the body. The PNS is divided into Somatic Nervous System and Autonomic Nervous System. The autonomic nervous system is further divided into Sympathetic and Parasympathetic systems.
What is the difference between the central nervous system and the peripheral?
The key difference between central and peripheral nervous system is that the central nervous system includes the brain and the spinal cord while the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs.
How can the peripheral nervous system be divided into?
Functionally, the peripheral nervous system (PNS) is divided into sensory (afferent) and motor (efferent) nerves, depending on whether they bring information to the CNS from sensory receptors or carry instructions towards muscles, organs or other effectors.
What does the peripheral nervous system look like?
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. The Cranial Nervous System nerves connect the brain to the eyes, mouth, ears and other parts of the head.
What are the major peripheral nerves?
Phrenic – C3-C5 – diaphragm
