10 Questions
What is the function of the Peripheral Nervous System?
Carries information about the body to the CNS and delivers commands from the CNS to alter body activities
Which division of the Autonomic Nervous System prepares the body for strenuous physical activity?
Sympathetic division
What is the function of the Motor division (efferent division) of the PNS?
Conducts action potential from the CNS to muscles and glands
Which part of the Central Nervous System controls homeostasis?
Brain
What type of muscles and glands does the Autonomic Nervous System transmit action potentials to?
Cardiac and smooth muscles and glands.
Which division of the nervous system conducts action potentials from sensory receptors to the CNS?
Sensory division
What is the function of the Parasympathetic division of the Autonomic Nervous System?
Regulates 'rest and digest' functions
What is the function of the Peripheral Nervous System?
Carries information about the different tissues of the body to the CNS
Which part of the Central Nervous System is responsible for controlling muscles and glands?
Central Nervous System
What does the Motor division (efferent division) of the PNS transmit action potentials to?
Skeletal muscles and glands
Study Notes
Functions of the Nervous System
- The Peripheral Nervous System (PNS) transmits information between the Central Nervous System (CNS) and the rest of the body.
Autonomic Nervous System
- The Sympathetic division prepares the body for strenuous physical activity.
- The Parasympathetic division has a calming effect, promoting relaxation and reducing stress.
Motor Division (Efferent Division) of the PNS
- The Motor division transmits action potentials to muscles and glands, controlling their functions.
Central Nervous System
- The Hypothalamus, a part of the CNS, controls homeostasis, regulating body temperature, hunger, and thirst.
- The CNS, specifically the Motor division, is responsible for controlling muscles and glands.
Sensory Division (Afferent Division) of the PNS
- The Sensory division conducts action potentials from sensory receptors to the CNS, transmitting information from the environment.
