Peripheral nervous system (PNS) motor neurons are responsible for controlling voluntary movements of skeletal muscles. They receive signals from the central nervous system (CNS) and transmit them to the muscles to initiate movement. PNS motor neurons are essential for activities like walking, talking, and grabbing objects.

Based on the main neurotransmitters the sympathetic nervous system can be classified as what-?
These are motor neurons located in the ganglia of the PNS
Which of the following cell types insulates neurons in the PNS?
neurona;
Does the ganglia contain sensory neurons?
No, the ganglia are clusters of nerve cell bodies located outside of the central nervous system. They primarily contain motor neurons that transmit signals from the central nervous system to muscles and glands for motor control. Sensory neurons transmit signals from sensory organs to the central nervous system for processing.
What supports neurons in PNS ganglia?
Neurons in the peripheral nervous system (PNS) ganglia are supported by satellite cells. Satellite cells surround neuron cell bodies, providing structural support, regulating nutrient exchange, and contributing to the health and function of the neurons.
Why sensory neurons are called as afferent neurons?
Sensory neurons are called afferent neurons because they carry information from sensory receptors to the central nervous system. "Afferent" means to carry inward, referring to the direction of information flow towards the central nervous system.
An impulse reaches the CNS from the PNS via the?
An impulse reaches the central nervous system (CNS) from the peripheral nervous system (PNS) through neurons. Sensory neurons in the PNS transmit signals to interneurons in the CNS, which then relay the information to motor neurons to generate a response.
Based on the main neurotransmitters the sympathetic nervous system can be classified as what-?
These are motor neurons located in the ganglia of the PNS
Are the interneurons in the PNS?
No, interneurons are found in the central nervous system (CNS), not the peripheral nervous system (PNS). The main function of interneurons is to relay signals between sensory neurons and motor neurons in the CNS.
What neuron carries impulses from the central nervous system to a muscle?
not sure , but i think they are called motor neurons and they are part of the PNS system
What neuron has the capacity for regeneration?
Motor neurons have the capacity to regenerate as long as the Schwann cells remain intact
Carry messages from the CNS to the muscles and glands in the PNS?
The main component of the PNS responsible for carrying messages from the CNS to the muscles and glands is the motor neuron. Motor neurons transmit electrical signals from the brain and spinal cord to the muscles and glands, allowing for voluntary and involuntary movements and responses.
What are collections of neurons?
nuclei in the CNS, ganglia in the PNS
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 neurons form the afferent division of the PNS?
For CH 12 of A&P the correct answer is: Sensory Neurons.
How do the CNS and the PNS interact?
The central nervous system (CNS) consists of the brain and spinal cord, while the peripheral nervous system (PNS) includes nerves outside of the CNS. The PNS relays information to and from the CNS through sensory and motor neurons. The CNS processes the information and sends out responses through the PNS to regulate activities in the body.
Which of the following cell types insulates neurons in the PNS?
neurona;
What cells os only found in the PNS?
Satellite cells are only found in the peripheral nervous system (PNS). These cells provide support and nutrients to the neurons in the PNS.
