Question 1

Which part of the neuron is responsible for maintaining the life of the cell?&#10;A)axon&#10;B)soma&#10;C)dendrite&#10;D)cell membrane

Accepted Answer

The soma, also known as the cell body, is responsible for maintaining the life of the neuron through various metabolic and synthetic processes, such as protein synthesis and energy production.

Question 2

The two main divisions of the nervous system are the ________ and ________.&#10;A)brain;spinal cord&#10;B)autonomic;somatic nervous systems&#10;C)peripheral nervous system;central nervous system&#10;D)glands;muscles

Accepted Answer

The peripheral nervous system includes all the nerves that extend outside of the brain and spinal cord, while the central nervous system includes the brain and spinal cord. The other options (A, B, and D) are subcategories within the main divisions of the nervous system.

Question 3

Which part of the nervous system takes the information received from the senses,makes sense out of it,makes decisions,and sends commands out to the muscles and the rest of the body?&#10;A)spinal cord&#10;B)brain&#10;C)reflexes&#10;D)interneurons

Accepted Answer

The brain is the control center of the nervous system, responsible for processing sensory information, making sense of it, making decisions based on it, and sending commands to the muscles and other parts of the body. While the spinal cord and interneurons play important roles in the nervous system, they do not have the same level of complexity and decision-making capability as the brain. Reflexes are automatic responses to specific stimuli and do not involve the higher-level functions of the brain.

Question 4

Which of the following is a function of the right hemisphere?&#10;A)perception,expression of emotion,and recognition of patterns&#10;B)sense of time and rhythm&#10;C)speech,handwriting,and calculation&#10;D)language processing in most individuals

Accepted Answer

The right hemisphere is responsible for perception, expression of emotion, and recognition of patterns. Choice B is associated with the right hemisphere, but is not its primary function. Choices C and D are associated with the left hemisphere.

Question 5

The part of the autonomic nervous system that is responsible for reacting to stressful events and bodily arousal is called the ______________ nervous system.&#10;A)central&#10;B)somatic&#10;C)sympathetic&#10;D)parasympathetic

Accepted Answer

The sympathetic nervous system is responsible for the "fight or flight" response to stress, including bodily arousal such as increased heart rate, respiration, and blood pressure. The central nervous system refers to the brain and spinal cord, and the somatic nervous system controls voluntary movements of skeletal muscles. The parasympathetic nervous system is responsible for the "rest and digest" response and helps to calm the body after a stressful event.

Question 6

What part of the brain acts as a relay station for incoming sensory information?&#10;A)hypothalamus&#10;B)thalamus&#10;C)cerebellum&#10;D)pituitary gland

Accepted Answer

The thalamus acts as a relay station for incoming sensory information, transmitting it to the appropriate areas of the cerebral cortex for processing.

Question 7

Hormones are___________.&#10;A)the female gonads&#10;B)chemicals released into the bloodstream by the endocrine glands&#10;C)chemicals found in the synaptic vesicles,which when released have an effect on the next cell&#10;D)the male gonads

Accepted Answer

Hormones are chemicals released into the bloodstream by the endocrine glands to regulate various physiological processes in the body.

Question 8

Which of the following neurotransmitters is implicated in both sleep and the inhibition of movement?&#10;A)serotonin&#10;B)GABA&#10;C)acetylcholine&#10;D)norepinephrine

Accepted Answer

GABA (gamma-aminobutyric acid) is a neurotransmitter that is involved in both sleep and the inhibition of movement. It is an inhibitory neurotransmitter that reduces the activity of neurons, leading to relaxation and sleep. GABAergic neurons also play a role in the regulation of movement, by inhibiting the activity of motor neurons in the brainstem and spinal cord. Serotonin (A), acetylcholine (C), and norepinephrine (D) are all involved in sleep regulation but not necessarily in the inhibition of movement.

Question 9

Which of the following regions contains the primary visual cortex?&#10;A)occipital lobe&#10;B)parietal lobe&#10;C)temporal lobe&#10;D)frontal lobe

Accepted Answer

The primary visual cortex, also known as V1 or striate cortex, is located in the occipital lobe at the back of the brain.

Question 10

A brain-imaging method using radio waves and magnetic fields of the body to produce detailed images of the brain is called ______________.&#10;A)electroencephalography (EEG)&#10;B)magnetic resonance imaging (MRI)&#10;C)positron-emission tomography (PET)&#10;D)computerized axial tomography (CT)

Accepted Answer

The brain-imaging method that uses radio waves and magnetic fields to produce detailed images of the brain is called magnetic resonance imaging (MRI). Electroencephalography (EEG) measures electrical activity in the brain, positron-emission tomography (PET) uses a small amount of radioactive substance to show how organs and tissues are functioning, and computerized axial tomography (CT) uses X-rays to create detailed pictures of the body's internal structures.
