AP Psychology Nervous systems

After touching a hot pan, Sam’s hand jerks back before he even realizes what happened. This automatic response is controlled by the:

• Autonomic nervous system

• Brainstem

• Spinal cord (central nervous system)

• Parasympathetic nervous system

Emma is preparing to give a speech. Her heart races, her mouth feels dry, and her palms sweat. These reactions are due to the activation of the:

• Parasympathetic nervous system

• Somatic nervous system

• Sympathetic nervous system

• Central nervous system

After the speech, Emma begins to calm down—her heart rate slows and her body relaxes. This change is controlled by the:

• Somatic nervous system

• Sympathetic nervous system

• Central nervous system

• Parasympathetic nervous system

Carlos kicks a soccer ball after receiving a signal from his brain to move his leg muscles. This voluntary motion is part of the:

• Somatic nervous system

• Autonomic nervous system

• Parasympathetic nervous system

• Sympathetic nervous system

Megan’s digestion speeds up and her pupils constrict as her body returns to a resting state. These changes are due to which system?

• Somatic nervous system

• Parasympathetic nervous system

• Sympathetic nervous system

• Central nervous system

The nervous system is divided into two major parts: the brain and spinal cord, which make up the:

• Peripheral nervous system

• Autonomic nervous system

• Central nervous system

• Somatic nervous system

The peripheral nervous system consists of the:

• Brain and spinal cord

• Only the spinal cord

• Somatic and autonomic nervous systems

• Sympathetic and parasympathetic systems

After hearing a loud crash, Jake’s body instantly goes into a high-alert state. His pupils dilate, and his breathing increases. This is an example of:

• Somatic nervous system activation

• Parasympathetic rebound

• Central nervous system shutdown

• Sympathetic nervous system activation

Walking, writing, and lifting objects involve which part of the nervous system?

• Somatic nervous system

• Sympathetic nervous system

• Autonomic nervous system

• Parasympathetic nervous system

The autonomic nervous system is best described as controlling:

• Reflexes and muscle tone

• Voluntary muscle movements

• Sensory input to the spinal cord

• Involuntary functions like heart rate and digestion
