What are the two most basic divisions of the nervous system?
somatic nervous system and autonomic nervous system
brain and spinal cord
sympathetic division and parasympathetic division
central nervous system and peripheral nervous system
In which part of the nervous system are the nerves in your hands and feet found?
peripheral
vascular
parasympathetic
skeletal
Which major division of the nervous system is comprised of the somatic nervous system and the autonomic nervous system?
central
afferent
What system allows you both to notice a buzzing near your ear and to swat the mosquito away?
autonomic nervous system
somatic nervous system
limbic system
endocrine system
What is the distinction between afferent and efferent nerves?
Afferent nerves take information to the central nervous system, while efferent nerves take information out from the central nervous system.
Afferent nerves are motor neurons, while efferent nerves are sensory neurons.
Afferent nerves are in the peripheral nervous system, while efferent nerves are in the central nervous system.
Afferent nerves take information to the muscles, while efferent nerves take information to the central nervous system.
Which division of the nervous system is necessary if you need to intentionally stand up or scratch your nose?
autonomic
sympathetic
somatic
Through which type of nerves does the brain send messages to the skeletal muscles in the legs when you are walking?
efferent
sensory
Which part of the nervous system controls digestion and the flow of blood?
motor
Which part of the nervous system diverts energy and resources in your body so that you can deal with emergency situations?
During what type of situations is the sympathetic nervous system in primary control?
stress
sexual
calm
fatigue
Zayed was walking down a dark street when he heard a car backfire. His heart started to race, and he began to perspire in response to this sudden, startling noise. Which division of the nervous system is responsible for his reactions?
sympathetic nervous system
parasympathetic nervous system
central nervous system
Karlette took some new medication for her hay fever. The medication made her heart race, and she became agitated and jittery. Which division of the nervous system has been activated by the medication?
Which division of your nervous system handles conservation of body resources, including blood pressure reduction and the promotion of digestion?
Which division of the nervous system is most likely to be in control of bodily processes during periods of rest and recovery for the body?
Robyn has just eaten a full meal and is now relaxing. Which specific division of her nervous system is in primary control at this time?
peripheral nervous system
Brenda was startled when a large shadow unexpectedly passed across her living room window. When she realized that it was just a cloud passing in front of the full moon, her racing heart began to slow, and her blood pressure started to return to normal. What division of the nervous system controlled the reactions as Brenda began to relax?
Johann took some medication for his flu symptoms. Later, Johann began to feel a little faint because the medication caused his heart to beat more slowly and his blood pressure to fall. What system was likely activated by the medication?
What does the central nervous system consist of?
the sympathetic and parasympathetic nervous systems
the somatic and autonomic nervous systems
the body’s sensory and motor neurons
the brain and the spinal cord
What are the protective membranes that protect the brain and spinal cord?
meninges
myelin sheaths
ventricles
glia
Which of the following protects the brain as a whole by providing an internal cushion?
ventricles filled with CSF
synaptic vesicles
Which of the following is the most accurate representation of the relationship between the brain and spinal cord?
The spinal cord communicates with the brain, but is separated by the meninges.
The spinal cord receives commands from the brain through nerves and cerebrospinal fluid.
The spinal cord and brain contribute independently to the central nervous system.
The spinal cord is an extension of the brain.
