Q: How do sensory neurons function in the nervous system?
- They carry signals from the CNS to muscles
- They connect neurons within the CNS
- They carry signals from sensory receptors to the CNS
- They transmit signals to the digestive system
A: They carry signals from sensory receptors to the CNS

Q: Which part of the nervous system is responsible for voluntary movements?
- Central nervous system
- Autonomic nervous system

- Peripheral nervous system
A: Somatic nervous system

Q: What role does the spinal cord play in the nervous system?
- It generates thoughts
- It relays messages between the brain and the body
- It produces hormones
- It digests food
A: It relays messages between the brain and the body

Q: How does the autonomic nervous system differ from the somatic nervous system?
- It controls voluntary movements
- It regulates involuntary functions
- It processes sensory information
- It connects the brain to the spinal cord
A: It regulates involuntary functions

Q: What happens when a person touches a hot surface?
- The brain sends signals to the heart
- Sensory neurons transmit pain signals to the spinal cord
- The spinal cord generates thoughts
- The limbs become paralyzed
A: Sensory neurons transmit pain signals to the spinal cord

Q: Which component of a neuron is responsible for receiving incoming signals?
- Axon
- Dendrites
- Cell body
- Synaptic terminals
A: Dendrites

Q: Why is understanding the nervous system important for healthcare professionals?
- It helps in diagnosing digestive disorders
- It is essential for understanding human physiology and behavior
- It aids in the study of plant biology
- It is not relevant to medical practice
A: It is essential for understanding human physiology and behavior

Q: How do neurotransmitters function in neuron communication?
- They provide structural support
- They transmit signals across the synaptic gap
- They generate electrical impulses
- They digest food
A: They transmit signals across the synaptic gap

Q: Which system prepares the body for stressful situations?
- Somatic nervous system
- Central nervous system
- Parasympathetic nervous system
- Sympathetic nervous system
A: Sympathetic nervous system

Q: What is the primary role of interneurons?
- To connect sensory and motor neurons
- To transmit signals to muscles
- To carry signals from sensory receptors
- To provide structural support
A: To connect sensory and motor neurons

Q: How does the peripheral nervous system contribute to homeostasis?
- By controlling voluntary movements
- By regulating involuntary bodily functions
- By processing sensory information
- By generating thoughts
A: By regulating involuntary bodily functions

Q: What is the function of the cell body in a neuron?
- To transmit signals to other neurons
- To receive signals from sensory receptors
- To integrate incoming signals and maintain cell health
- To connect neurons within the CNS
A: To integrate incoming signals and maintain cell health

Q: Which part of the nervous system includes all the nerves outside the CNS?
- Central nervous system
- Somatic nervous system
- Peripheral nervous system
- Autonomic nervous system
A: Peripheral nervous system

Q: What does the term "homeostasis" refer to in the context of the nervous system?
- The body's ability to maintain stable internal conditions
- The process of digestion
- The generation of thoughts
- The movement of muscles
A: The body's ability to maintain stable internal conditions

Q: How can understanding the structure of neurons aid in the study of neurological disorders?
- It helps in understanding digestive processes
- It provides insights into how signals are transmitted and processed
- It is not relevant to neurological disorders
- It focuses on muscle function
A: It provides insights into how signals are transmitted and processed
