Autonomic Nervous System
Somatic Nervous System
Central Nervous System
Peripheral Nervous System
What does the somatic nervous system control?

What is the role of the parasympathetic nervous system?
To increase heart rate and breathing
To control voluntary movements
To calm the body and return it to balance
To sense the external world
Which nervous system is thought to work independently of the CNS?
Peripheral Nervous System
Enteric Nervous System

What is a neural circuit?
A chain of neurons transmitting signals
A muscle contraction mechanism
A type of glial cell
A part of the digestive system
Which neurons serve as intermediaries between afferent and efferent neurons?
Motor Neurons
Sensory Neurons
Glial Cells
