The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.
What are the major components of the peripheral nervous system?
The peripheral nervous system itself is divided into two parts: the somatic nervous system and the autonomic nervous system. Each of these components plays a critical role in how the peripheral nervous system operates.
What are the three components of 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 two components of the peripheral nervous system?
The peripheral nervous system is further subdivided into the somatic nervous system and the autonomic nervous system. The somatic nervous system consists of nerves that go to the skin and muscles and is involved in conscious activities.
Which of the following are components of the peripheral nervous system quizlet?
The peripheral nervous system includes the cranial nerves (connected to brain innervate the head), spinal nerves (connected to spinal cord innervates the rest of the body), and ganglia (collections of neuron cell bodies in the PNS).
Is ganglia components of PNS?
The PNS consists of all nervous tissue outside of the brain and spinal cord. It includes the ganglia, nerves, and receptors, as they are found in various parts of the body.
Which of the following is not the component of the PNS?
brain is NOT a part of the peripheral nervous system. The brain, brain stem and spinal cord are all components of 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 are the 7 major peripheral nerves?
Nerves In the Peripheral Nervous System
- Brachial plexus (radial nerve, median nerve, ulnar nerves)
- Peroneal nerve (foot drop)
- Femoral nerve.
- Lateral femoral cutaneous nerve.
- Sciatic nerve.
- Spinal accessory nerve.
- Tibial nerve.
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 is CNS and PNS?
Our nervous system is divided in two components: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which encompasses nerves outside the brain and spinal cord.
