The roles of the subdivisions of the CNS and PNS

The divisions of the autonomic nervous system include the

• peripheral nervous system and the central nervous system

• parasympathetic nervous system and the somatic nervous system

• parasympathetic nervous system and the sympathetic nervous system

• sympathetic nervous system and the somatic nervous system

The fight-flight response is a direct function of

• the automatic nervous system

• the somatic nervous system

• the parasympathetic nervous system

• the sympathetic nervous system

Tony picks up a cup of coffee, but decides it is too hot to hold comfortably. He carefully places it back down onto the table. Heat from the cup is detected by sensory receptors in Tony's fingers, which is part of the ​ (a)   nervous system. Sensory signals are sent to the ​ (b)   nervous system for processing, where Tony decides that the cup is too hot to hold comfortably.

Motor information is then sent from the ​ (c)   nervous system to the skeletal muscles, via the ​ (d)   nervous system, to put the cup down.

• somatic
• central
• autonomic
• peripheral
• sympathetic
• parasympathic

Which of the following statements is incorrect?

• the peripheral nervous system is responsible for transmitting sensory information from the body to the brain

• the peripheral nervous system is responsible for transmitting signals from the central nervous system to the internal organs

• the brain is responsible for coordinating all voluntary behaviour and thought

Pat was sitting in his Psychology class when the teacher asked him to identify the divisions of the human nervous system. His heart rate immediately increased, and he started to sweat. He was unable to answer the teacher's question in class, but when he was home in his room later that day, he had no problem recalling the answer.

The physiological reaction that Pat experienced was under the control of which division of the nervous system?

• central

• somatic

• parasympathetic

• autonomic

Georgia was walking towards the pool when she stood barefoot on a sharp object. She immediately pulled her foot away.

• afferent pathways

• efferent pathways

• spinal cord
