Question 1

The autonomic nervous system helps to maintain a relatively consistent body temperature despite environmental temperature changes.This best illustrates

Accepted Answer

The autonomic nervous system, specifically its sympathetic and parasympathetic branches, works to maintain homeostasis within the body. This includes regulating body temperature in response to changes in the environment. Therefore, the best choice is D, homeostasis.

Question 2

The division of the peripheral nervous system controlling the body's skeletal muscles is the

Accepted Answer

The somatic nervous system is responsible for controlling the body's skeletal muscles, which allows for voluntary movements. The motor nervous system refers to both the somatic and autonomic nervous systems, which control muscle movement and other involuntary functions. The sympathetic and parasympathetic nervous systems are both parts of the autonomic nervous system, which controls involuntary functions such as heart rate and digestion. Neither of these systems specifically controls skeletal muscle movement.

Question 3

The parasympathetic nervous system is to the sympathetic nervous system as ________ is to ________.

Accepted Answer

The answer of The parasympathetic nervous system is to the...

Question 4

Messages are transmitted from your spinal cord to your digestive system's stomach muscles by the

Accepted Answer

The sympathetic nervous system is part of the autonomic nervous system that controls the body's involuntary activities and is responsible for the fight or flight response, including transmitting messages to the stomach muscles for digestion.

Question 5

When Mr.Valdez thought his 1-year-old daughter had fallen down the stairs,his heartbeat accelerated,his blood pressure rose,and he began to perspire heavily.Mr.Valdez's state of arousal was activated by his ________ nervous system.

Accepted Answer

The sympathetic nervous system is responsible for activating the body's fight-or-flight response in times of stress or danger. In this scenario, Mr. Valdez's belief that his daughter may have fallen down the stairs likely triggered this response, resulting in his increased heart rate, blood pressure, and sweating. The parasympathetic nervous system, on the other hand, is responsible for promoting rest and relaxation in the body. The somatic nervous system controls voluntary movements, and the central nervous system includes the brain and spinal cord.

Question 6

For you to be able to run,________ must relay messages from your central nervous system to your leg muscles.

Accepted Answer

Motor neurons are responsible for carrying signals from the central nervous system to muscles, allowing for voluntary movement such as running. Interneurons are responsible for relaying messages between sensory and motor neurons, while afferent neurons transmit signals from sensory receptors to the central nervous system. The autonomic nervous system controls involuntary actions such as heart rate and digestion, but is not directly involved in voluntary movement.

Question 7

The part of the peripheral nervous system that controls the movement of your arms when you write is the

Accepted Answer

The somatic nervous system is responsible for voluntary movements of the body, such as arm movement when writing. The autonomic nervous system regulates involuntary functions such as heart rate and digestion, while the sympathetic and parasympathetic branches of the autonomic nervous system control the fight or flight response and rest and digest response, respectively.

Question 8

The sympathetic nervous system

Accepted Answer

The sympathetic nervous system is part of the autonomic nervous system that prepares the body for physical activity by inhibiting digestion and accelerating the heartbeat, among other effects. This is often referred to as the "fight or flight" response.

Question 9

When Jenny saw that a large barking dog was enclosed by a very high fence,her racing heartbeat began to slow.The slowing of her heartbeat was most directly regulated by her

Accepted Answer

The parasympathetic nervous system is responsible for the relaxation response, which slows down the body's physiological activities such as heart rate, breathing rate, and blood pressure. In this scenario, Jenny's racing heartbeat slowed down after seeing the enclosed dog, so we can infer that her parasympathetic nervous system was activated.

Question 10

...

Question 11

Nerves are neural cables formed from bundles of

Accepted Answer

Nerves are formed from bundles of axons, which are the long, thread-like extensions of neurons that transmit electrical signals throughout the nervous system. Endorphins are neurotransmitters that act on receptors in the brain to reduce pain and induce pleasurable feelings, while interneurons are a type of neuron that transmit signals between other neurons. Lesions refer to damage or abnormalities in tissue, and are not directly related to nerve function.

Question 12

Information travels from spinal cord to the brain through

Accepted Answer

Interneurons are the neurons that connect sensory neurons to motor neurons, and are responsible for transmitting information between them. In the case of spinal cord to brain communication, interneurons are the neurons that transmit sensory information from the spinal cord to the brain.

Question 13

Botulin blocks the release of ACh.Botulin is best described as a(n)

Accepted Answer

Botulinum toxin (Botulin) is an antagonist that blocks the release of acetylcholine (ACh) at neuromuscular junctions, leading to muscle paralysis. It does not function as an opiate or glutamate, and it is not a neurotransmitter itself.

Question 14

Efferent is to afferent as ________ is to ________.

Accepted Answer

Efferent neurons (motor neurons) carry signals away from the central nervous system to effectors such as muscles, whereas afferent neurons (sensory neurons) carry signals towards the central nervous system from sensory receptors.

Question 15

When Dirk was stung by a bee,the pain message was transmitted to his spinal cord by the ________ nervous system.

Accepted Answer

The peripheral nervous system is responsible for carrying sensory information from the body's central nervous system (brain and spinal cord) to the rest of the body. When Dirk was stung by a bee, the pain message was transmitted to his spinal cord through the sensory neurons of the peripheral nervous system. The sympathetic and parasympathetic nervous systems are subdivisions of the autonomic nervous system and are responsible for regulating involuntary functions, such as heart rate and digestion. The central nervous system includes the brain and spinal cord, but does not transmit sensory information to itself.

Question 16

Information is carried from the body's tissues and sensory receptors to the central nervous system by

Accepted Answer

Sensory neurons are responsible for carrying information from the body's tissues and sensory receptors to the central nervous system. Interneurons are located entirely within the central nervous system and are responsible for processing and relaying information between sensory and motor neurons. Motor neurons are responsible for carrying information from the central nervous system to muscles and glands, causing them to move or secrete substances. Endocrine glands are not responsible for carrying information to the central nervous system, but instead secrete hormones directly into the bloodstream.

Question 17

The parasympathetic nervous system is a division of the ________ nervous system.

Accepted Answer

The parasympathetic nervous system is a division of the autonomic nervous system, which is responsible for controlling involuntary bodily functions such as heart rate and digestion. The somatic nervous system, on the other hand, is responsible for voluntary movements such as walking and talking. The central nervous system includes the brain and spinal cord. The sympathetic nervous system is another division of the autonomic nervous system, which is responsible for the fight or flight response in stressful or dangerous situations.

Question 18

Motor neurons are an important part of the

Accepted Answer

Motor neurons are a type of neuron found in the peripheral nervous system, responsible for transmitting signals from the central nervous system to muscles, resulting in voluntary or involuntary movement.

Question 19

The brain and spinal cord form the

Accepted Answer

The brain and spinal cord make up the central nervous system, which is responsible for processing and coordinating sensory and motor information. Option A (autonomic nervous system) refers to the part of the peripheral nervous system that controls involuntary functions such as heart rate and digestion. Option B (somatic nervous system) refers to the part of the peripheral nervous system that controls voluntary movements such as walking and talking. Option D (endocrine system) is a separate system responsible for producing and regulating hormones.

Question 20

The body's speedy electrochemical information network is called the

Accepted Answer

The nervous system is responsible for transmitting information throughout the body quickly via electrochemical signals. The endocrine system also uses chemicals to transmit information, but it does so more slowly through the bloodstream. The circulatory system is responsible for transporting blood and nutrients throughout the body, while the cognitive system refers to the process of thinking and mental processing.
