What is controlled by the somatic division of the PNS?
The somatic division of the peripheral nervous system controls voluntary movements, such as skeletal muscle contractions. It also transmits sensory information from the skin, muscles, and joints to the central nervous system for processing.
Which branch of PNS controsl voluntary activities such as walking?
The somatic nervous system controls voluntary activities such as walking. It consists of motor neurons that transmit signals from the central nervous system to skeletal muscles, allowing for conscious control of movement.
What do PNS motor neurons do?
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.
What are controlled by somatic division of the PNS?
The afferent nerves of the somatic nervous system carry sensory signals from the skin, skeletal muscles, joints, ears, eyes, tongue, etc. to the central nervous system, while the efferent nerves of the somatic nervous system carry motor signals from the central nervous system to the skeletal muscles.
What does the efferent division of the PNS do?
The efferent division of the PNS carries signals from the central nervous system to the muscles and glands to control responses. It consists of the somatic nervous system, which controls voluntary movements, and the autonomic nervous system, which regulates involuntary functions such as heart rate and digestion.
What PNS system controls skeletal muscles?
The somatic nervous system controls skeletal muscles. It is responsible for voluntary movements and receives input from sensory neurons to help coordinate muscle contractions.
What is controlled by the somatic division of the PNS?
The somatic division of the peripheral nervous system controls voluntary movements, such as skeletal muscle contractions. It also transmits sensory information from the skin, muscles, and joints to the central nervous system for processing.
Subdivision of the pns that controls voluntary activities such as the activation of skeletal muscle?
the Somatic nervous system

What does the efferent division of the PNS do?
The efferent division of the PNS carries signals from the central nervous system to the muscles and glands to control responses. It consists of the somatic nervous system, which controls voluntary movements, and the autonomic nervous system, which regulates involuntary functions such as heart rate and digestion.
The system consists of nerves that transmit impulses back and forth between the central nervous system the skeletal muscles and the skin?
The Peripheral Nervous System is made up of 12 pairs of cranial nerves which transmit signals from the joints, skeletal muscles and skin to the brain. The PNS is further subdivided into the Somatic Nervous System and the Viscera.
How does the Sympathetic Division of the PNS regulate the body during exercise?
The Sympathetic Division of the PNS activates during exercise to increase heart rate, dilate airways, and redirect blood flow to skeletal muscles. This response helps to deliver more oxygen and nutrients to muscles, improving performance and endurance.
What are the two main systems that belong to the pns?
The two main systems of the peripheral nervous system (PNS) are the somatic nervous system, which controls voluntary movements, and the autonomic nervous system, which regulates involuntary functions like heart rate and digestion.
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.
Is PNS involved in reflex actions?
Yes, the peripheral nervous system (PNS) is involved in reflex actions. Reflex arcs allow sensory information to be processed in the spinal cord and produce motor responses without involving the brain. The PNS carries the sensory information to the spinal cord and the motor responses back to the muscles or glands.
What organ system does hypothalamus belong to?
The hypothalamus controls the autonomic functions of the peripheral nervous system (PNS). It helps maintain homeostatic functions.
