The main function of dendrites is to:
Send signals
Receive signals
Generate impulses
Transmit electrical signals to other neurons
The axon of a neuron is responsible for:
Input
Reception
Output
Chemical communication at the synapse
Which part of the neuron generates the action potential?
Dendrite
Cell body
Axon hillock
Terminal bouton of the neuron
The synaptic cleft refers to:
Axon end
Cell membrane
Space between neurons
Gap where neurotransmitters are released
Neurotransmitters are best described as:
Hormones
Electrical signals
Chemical messengers
Proteins that protect the neuron
Reuptake occurs when neurotransmitters:
Are destroyed
Are reabsorbed
Enter the brain
Stimulate the next neuron repeatedly
The central nervous system consists of the:
Brain only
Spinal cord only
Brain and spinal cord
Brain, nerves, and sense organs
The spinal cord mainly functions to:
Control emotions
Send sensory and motor information
Produce hormones
Regulate consciousness and alertness
Damage to the spinal cord may affect:
Hearing only
Vision only
Motor control
Personality and intelligence
The somatic nervous system controls:
Digestion
Heart rate
Voluntary movement
Involuntary glandular activity
Reflex actions are processed mainly through the:
Brain cortex
Spinal cord
Cerebellum
Autonomic nervous system
The autonomic nervous system primarily regulates:
Conscious thought
Voluntary muscles
Reflex learning
Internal organs and glands
The sympathetic nervous system prepares the body for:
Sleep
Relaxation
Emergency situations
Digestion and energy storage
Increased heart rate during stress is controlled by the:
Somatic system
Parasympathetic system
Sympathetic system
Central nervous system as a whole
The parasympathetic nervous system is mainly involved in:
Fight or flight
Rest and digest
Emergency response
Muscle contraction and movement
Which effect is associated with parasympathetic activation?
Dilated pupils
Increased digestion
Faster breathing
Release of adrenaline into the bloodstream
The main function of the peripheral nervous system is to:
Control thinking
Protect the brain
Connect the CNS to the rest of the body
Regulate consciousness and awareness
The peripheral nervous system is divided into which TWO main components?
Brain and spinal cord
Sensory and motor nerves
Central and autonomic systems
Somatic and Autonomic Nervous System
The main role of the peripheral nervous system is to:
Control thinking
Store memories
Link the central nervous system to the rest of the body
Process information and make decisions
Mirror neurons are important because they:
Control speech
Regulate sleep
Fire during action and observation
Produce neurotransmitters for motor movement
