What are the two groups of nerves into which the pns is divided?
The peripheral nervous system (PNS) is divided into two groups of nerves: sensory nerves, which transmit information from the body to the central nervous system, and motor nerves, which transmit information from the central nervous system to the muscles and glands to produce a response.
Collections of neuron cell bodies associated with nerves in the PNS?
Ganglia
Is the majority of the nervous system contained in the CNS or the PNS?
the PNS as the cental nervous system only consists of the brain and spinal cord. where as the rest of the body is covered by all the nerves which are included in the PNS
What is the name for bundles of myelinated axons in the PNS?
The name for bundles of myelinated axons in the peripheral nervous system (PNS) is "nerves." Nerves serve the purpose of transmitting sensory information and motor impulses between different parts of the body and the central nervous system.
How many pairs are of the cranial nerves?
There are 12 pairs of cranial nerves that are part of the PNS. These nerves are sensory, mixed and mostly motor.
What are the components of PNS?
The peripheral nervous system (PNS) comprises nerves outside the brain and spinal cord. It includes sensory nerves (transmitting sensory information to the central nervous system) and motor nerves (transmitting commands from the brain to muscles and glands), as well as the autonomic nervous system (regulating involuntary bodily functions).
List the structures of the CNS and PNS?
Peripheral Nervous System (PNS)Contains all nerves outside of the brain & spinal cord.Somatic Nervous System (Voluntary)Two types: Sensory (or afferent) and motor (or efferent) nerves
What nerves are included in the peripheral nervous system?
PNS includes all nerves throughout the body, except the brain and spinal cord.
What is the PNS made up of?
it is made up by nerves and associated cells that are not part of the brain and the spinal cord, included here are cranial nerves that pass through openings in the skull and stimulate regions of the head and neck, spinal nerves, and ganglia(ganglia are collections of nerve cell bodies).
What is the PNS system?
The peripheral nervous system (PNS) consists of all the nerves outside of the brain and spinal cord. It is responsible for transmitting information between the body and the central nervous system, allowing for sensory perception and motor function. The PNS includes sensory nerves that convey information to the brain and motor nerves that control muscle movement.
What connects the cns to the pns?
The central nervous system (CNS) is connected to the peripheral nervous system (PNS) through spinal nerves and cranial nerves. These nerves serve as pathways for transmitting signals between the brain and spinal cord (CNS) and the rest of the body (PNS). The spinal cord relays information to and from the body, while cranial nerves facilitate communication between the brain and structures in the head and neck. This connection allows for coordinated bodily functions and responses to stimuli.
Are nerves more myelinated or unmyelinated in the CNS?
Nope. They can be found in the PNS as well. The myelinated ones in the CNS are made my Schwann cells. And the ones made in the PNS are made by oligodendrocytes.
