Which statement explains the difference between a nerve that is connected to the skin and a nerve that is connected to a muscle?

A
The nerve that is connected to skin is a motor neuron; the nerve that is connected to a muscle is a sensory neuron.
B
The nerve that is connected to skin receives stimuli information from the external environment; the nerve that is connected to a muscle receives processed stimuli information from the brain.
C
The nerve that is connected to skin is part of the central nervous system; the nerve that is connected to a muscle is part of the peripheral nervous system.
D
The nerve that is connected to skin helps the body maintain homeostasis; the nerve that is connected to a muscle supports the body so it can stand upright and move from place to place.

Read the passage below.Prior to the 1970s, scientists thought that new neurons could not be generated in adult brains. In the 1970s, Dr. Goldman and Dr. Nottbohm discovered that hormones injected in adult songbirds could cause female songbirds to develop new neurons.Which statement best exemplifies the scientific principle that was involved in this case?

A
New experiments do not affect science because science remains constant.
B
New experiments can affect future scientific explanations.
C
New experiments can affect previous scientific explanations.
D
New experiments yield untrustworthy data and should be carefully considered.
5

Which structure would be unaffected by the peripheral nervous system?

A
meninges
B
sense organs
C
muscles
D
glands
6

What is the role of sensory neurons in the breakdown of food?

A
Sensory neurons digest carbohydrates in the digestive tract.
B
Sensory neurons cause chewing of food in the mouth.
C
Sensory neurons release hormones so that the brain can cause the food to be moved and digested in the digestive tract.
D
Sensory neurons sense the presence of food and relay the information to the brain so that food can be moved and digested in the digestive tract.
7

How does a motor neuron work when a mosquito is seen on an arm?

A
It receives stimuli information from the skin and sends it to the brain where it is processed.
B
It receives processed information from the brain, causing the muscles of the arm and hands to remove the mosquito from the arm.
C
It processes information from the stimuli receiver and makes the brain aware that there is a mosquito on the arm.
D
It makes the arm numb from the effect of the mosquito bite.
8

The sympathetic and parasympathetic nervous systems are both a part of which division of the nervous system?

A
central nervous system
B
voluntary motor system
C
somatic nervous system
D
autonomic nervous system
9

Which statement differentiates sensory neurons and motor neurons?

A
Sensory neurons are found in the brain; motor neurons are found in the spinal column.
B
Sensory neurons carry stimuli information to the brain; motor neurons carry processed information to muscles and glands.
C
Sensory neurons process the information from the sensory organs; motor neurons process the information from the motor parts of the body, such as muscles.
D
Sensory neurons produce involuntary responses; motor neurons produce voluntary responses.
10

Which best describes the parasympathetic nervous system?

A
the brain and spinal cord
