Die Flashcards
What is the primary function of the nervous system?
To coordinate and control bodily functions and respond to internal and external stimuli.
True or False: The nervous system is divided into the central and peripheral nervous systems.
True
Fill in the blank: The __________ nervous system includes the brain and spinal cord.
central
What does the peripheral nervous system consist of?
Nerves that branch out from the central nervous system to the rest of the body.
What are the two main types of cells in the nervous system?
Neurons and glial cells.
Multiple choice: Which part of the neuron receives signals?
Dendrites
What is the function of myelin sheaths?
To insulate axons and increase the speed of nerve impulse transmission.
True or False: The autonomic nervous system controls voluntary movements.
False
What are the two divisions of the autonomic nervous system?
Sympathetic and parasympathetic nervous systems.
Fill in the blank: The __________ nervous system prepares the body for ‘fight or flight’ responses.
sympathetic
What role do neurotransmitters play in the nervous system?
They transmit signals across synapses between neurons.
Multiple choice: Which neurotransmitter is primarily associated with mood regulation?
Serotonin
What is a reflex arc?
The neural pathway that controls a reflex action.
True or False: The brain is the only organ that can generate electrical impulses.
False
What part of the brain is responsible for balance and coordination?
Cerebellum
Fill in the blank: The __________ lobe is primarily responsible for processing visual information.
occipital
What is the function of the spinal cord?
To transmit signals between the brain and the rest of the body.
Multiple choice: Which structure connects the left and right hemispheres of the brain?
Corpus callosum
What is the role of the hypothalamus?
To regulate homeostasis and control the autonomic nervous system.
True or False: The somatic nervous system controls involuntary bodily functions.
False
What is the primary function of glial cells?
To support and protect neurons.
Fill in the blank: The __________ is the outer layer of the brain.
cortex
What is an action potential?
A rapid change in electrical charge that travels along the axon of a neuron.
Multiple choice: Which type of neuron carries signals away from the central nervous system?
Motor neurons
