A)slowing down the body and keeping it calm
B)involuntary functions such as circulation and digestion
C)the fight-or-flight response
D)voluntary motor movements and receiving sensory signals

Accepted Answer

The somatic nervous system is responsible for voluntary motor movements and receiving sensory signals, allowing us to consciously control our muscles and to perceive touch, temperature, pain, and position.

Question 5

The sympathetic and parasympathetic nervous systems play complementary roles in maintaining a balanced and constant internal state called __________.
A)metasynthesis
B)homeostasis
C)neural plasticity
D)resting potential

Accepted Answer

Homeostasis refers to the process by which living organisms regulate their internal environment to maintain a stable, constant condition, balancing factors such as temperature, pH, hydration, and energy levels. The sympathetic and parasympathetic nervous systems contribute to this balance by controlling and adjusting bodily functions in response to changing external and internal conditions.

Question 6

The function of the interneurons is to ___________.
A)carry information from the sense organs to the brain or spinal cord
B)carry information from the brain and spinal cord to various muscles or organs
C)perform all neural functions except the sensory and motor functions in the nervous system
D)connect neurons with glial cells

Accepted Answer

Interneurons, also known as association neurons, are responsible for processing and integrating information within the central nervous system, essentially performing all neural functions that are not directly involved in sensing external stimuli or initiating muscle movements. They act as a link between sensory inputs and motor outputs.

Question 7

Which mechanism will deactivate neurotransmitters and take it back into the presynaptic axon terminal?
A)Repackage
B)Recycle
C)Reabsorption
D)Reuptake

Accepted Answer

Reuptake is the process by which neurotransmitters are taken back into the presynaptic neuron after being released into the synaptic cleft, effectively deactivating them and allowing for their reuse.

Question 8

The breathing centers are located in the pons within the central nervous system. The pons is part of?
A)forebrain
B)midbrain
C)hindbrain
D)spinal cord

Accepted Answer

The pons is part of the hindbrain, which also includes the cerebellum and medulla oblongata. The hindbrain is responsible for various functions including motor control, sensory analysis, and controlling autonomic functions such as breathing.

Question 9

Jon hears his phone ring and reaches out his hand to answer it. Which type of neurons did Jon use to input the sound of the phone?
A)interneurons
B)sensory neurons
C)exoneurons
D)motor neurons

Accepted Answer

Sensory neurons are responsible for transmitting sensory information from the body's periphery towards the central nervous system, allowing Jon to hear the sound of the phone ringing.

Question 10

In the human body, which nervous system is responsible for activating the body for such things as the fight-or-flight response?
A)Autonomic
B)Somatic
C)Sympathetic
D)Parasympathetic

Accepted Answer

The sympathetic nervous system is responsible for activating the body's fight-or-flight response, preparing the body to respond to perceived threats by increasing heart rate, blood pressure, and releasing stored energy.

Question 11

Which division of the nervous system is responsible for respiration, blood circulation, and digestion as well as motivation, emotional behaviour, and stress response?
A)Autonomic nervous system
B)Somatic nervous system
C)Parasympathetic nervous system
D)Central nervous system

Accepted Answer

The autonomic nervous system regulates involuntary functions such as respiration, blood circulation, and digestion, and is also involved in emotional behavior and stress response.

Question 12

The division of the peripheral nervous system that senses the body's internal functions and controls the glands and the smooth muscles is called the _______________________ nervous system.
A)parasympathetic
B)sympathetic
C)somatic
D)autonomic

Accepted Answer

The autonomic nervous system is responsible for regulating involuntary body functions, such as blood flow, heartbeat, digestion, and breathing, and it includes both the sympathetic and parasympathetic nervous systems.

Question 13

If you are going for a run and your airways dilate to breathe in more oxygen then this would be a result of which nervous system working?
A)Somatic sensory
B)Somatic motor
C)Visceral motor
D)Enteric

Accepted Answer

The dilation of airways to increase oxygen intake during activities like running is controlled by the autonomic (visceral) nervous system, specifically the sympathetic division, which is responsible for the "fight or flight" response, including increasing heart rate and dilating airways.

Question 14

We are comparing two individuals, individual 1 is resting at home after having dinner. Individual 2 is in the jungle running away from a wild animal. Which nervous systems are activated in individuals 1 and 2?
A)1: Sympathetic 2: parasympathetic
B)1: Parasympathetic 2: sympathetic
C)1: Sympathetic 2: sympathetic
D)1: Parasympathetic 2: parasympathetic

Accepted Answer

Individual 1 is in a relaxed state, which activates the parasympathetic nervous system responsible for "rest and digest" functions. Individual 2 is in a high-stress situation, activating the sympathetic nervous system responsible for "fight or flight" responses.

Question 15

Jon hears his phone ring and reaches out his hand to answer it. Which type of neurons did Jon use to move his hand?
A)Interneurons
B)Sensory neurons
C)Exoneurons
D)Motor neurons

Accepted Answer

Motor neurons are responsible for carrying signals from the central nervous system to the muscles to produce movement, such as reaching out to answer a phone.

Question 16

A neuron sends an action potential to the muscle that contracts your eyelid. This neuron would be classified as a(n) __________________ neuron.
A)excitatory
B)action
C)sensory
D)motor

Accepted Answer

Motor neurons are responsible for transmitting impulses from the brain or spinal cord to a muscle or gland, causing it to act. In this case, the neuron sending an action potential to the muscle that contracts your eyelid is performing a motor function.

Question 17

In the human body, which nervous system is responsible for calming and slowing down the body processes?
A)Somatic
B)Parasympathetic
C)Sympathetic
D)Autonomic

Accepted Answer

The parasympathetic nervous system is responsible for calming and slowing down the body processes, often referred to as the "rest and digest" system. It conserves energy as it slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles in the gastrointestinal tract.

Question 18

If the nervous system is like a car, then the sympathetic nervous system and the parasympathetic nervous system would be most like the ___________.
A)steering wheel and the engine
B)gas pedal and the brake pedal
C)taillights and the headlights
D)front seat and the back seat

Accepted Answer

The sympathetic and parasympathetic nervous systems are part of the autonomic nervous system, controlling involuntary body functions. The sympathetic nervous system is like the gas pedal, activating the "fight or flight" response, increasing heart rate, and releasing adrenaline. The parasympathetic nervous system is like the brake pedal, promoting the "rest and digest" response, slowing down the heart rate, and conserving energy.

Question 19

Hormones to the pituitary gland is like sleep and arousal to?
A)Thalamus
B)Amygdala
C)Cerebellum
D)Pons

Accepted Answer

The pons is part of the brainstem that plays a key role in controlling sleep and arousal, similar to how the pituitary gland regulates hormones.

Question 20

The type of neuron that carries input messages from the sense organs to the central nervous system is called the ___________.
A)interneuron
B)sensory neuron
C)exoneuron
D)motor neuron

Accepted Answer

Sensory neurons are responsible for carrying input messages from the sense organs to the central nervous system, allowing the body to respond to environmental stimuli.
