What is the primary function of the central nervous system?
✔✔ To process and integrate sensory information, and to coordinate and direct responses to
stimuli.
How does the autonomic nervous system differ from the somatic nervous system?
✔✔ The autonomic nervous system regulates involuntary physiological functions such as heart
rate and digestion, while the somatic nervous system controls voluntary muscle movements.
What role do neurotransmitters play in neural communication?
✔✔ Neurotransmitters are chemicals that transmit signals across a synapse from one neuron to
another, facilitating communication within the nervous system.
What is the function of the myelin sheath?
1
, ✔✔ The myelin sheath insulates nerve fibers, increasing the speed and efficiency of electrical
signal transmission along the neuron.
How does the sympathetic nervous system affect the body during stress?
✔✔ It activates the "fight or flight" response, increasing heart rate, dilating pupils, and
redirecting blood flow to essential organs and muscles.
What are the primary components of the peripheral nervous system?
✔✔ The peripheral nervous system consists of all the nerves outside the central nervous system,
including cranial nerves and spinal nerves.
How is a reflex arc structured, and what is its purpose?
✔✔ A reflex arc is a neural pathway that controls a reflex action, consisting of a sensory neuron,
an interneuron, and a motor neuron, allowing for rapid, involuntary responses to stimuli.
