NEUROBIOLOGY COMPREHENSIVE EXAM UPDATED
QUESTIONS AND ANSWERS GRADED A+
✔✔What is the difference between agonists and antagonists? - ✔✔Agonists stimulate
responses, while antagonists inhibit or block responses.
✔✔What comprises the central nervous system (CNS)? - ✔✔The brain and spinal cord.
✔✔What is the function of the peripheral nervous system (PNS)? - ✔✔It connects the
CNS to the rest of the body through sensory and motor neurons.
✔✔What are nerves made of? - ✔✔Bundled axons that connect the CNS to muscles,
glands, and sense organs.
✔✔How do sensory and motor neurons work when running to a friend? - ✔✔Sensory
neurons carry information to the brain, while motor neurons send commands from the
brain to the muscles.
✔✔What is the somatic nervous system (SNS)? - ✔✔It controls the skeletal muscles
that are under conscious control.
✔✔What does the autonomic nervous system (ANS) do? - ✔✔It regulates glands and
organs that function unconsciously.
✔✔What is the role of the sympathetic nervous system? - ✔✔It prepares the body for
stressful situations by arousing it.
✔✔What does the parasympathetic nervous system do? - ✔✔It calms the body and
conserves energy.
✔✔What is the endocrine system? - ✔✔It is the system of glands and organs that
produce hormones.
✔✔What is the function of hormones? - ✔✔They coordinate various bodily functions,
including growth, metabolism, and mood.
✔✔What do adrenal glands do? - ✔✔They secrete hormones that trigger the fight or
flight response.
✔✔What is the role of the pituitary gland? - ✔✔It secretes hormones that regulate
growth and affect other glands.
, ✔✔What are the main components of the hindbrain? - ✔✔The hindbrain consists of the
medulla, pons, and cerebellum, which control essential survival functions like breathing
and coordination.
✔✔Where is the midbrain located and what does it do? - ✔✔The midbrain is located
atop the brainstem and connects the hindbrain to the forebrain, controlling some motor
movements and transmitting auditory and visual information.
✔✔What role does the pons play in the brain? - ✔✔The pons connects the thalamus
and medulla, facilitating breathing, sleep cycles, and facial movements.
✔✔What is the function of the medulla? - ✔✔The medulla, located at the base of the
brainstem, regulates heartbeat and breathing automatically.
✔✔What does the reticular formation control? - ✔✔The reticular formation, which travels
through the thalamus and brainstem, manages consciousness and arousal.
✔✔What does the thalamus do? - ✔✔The thalamus, located at the top of the brainstem,
oversees cognition, memory, and alertness.
✔✔What is the function of the cerebellum? - ✔✔The cerebellum, found at the rear of the
brainstem, processes sensory information and coordinates movement, enabling
nonverbal learning and memory.
✔✔What is the limbic system? - ✔✔The limbic system is located below the cerebral
hemispheres and is responsible for processing emotions and drives.
✔✔What does the amygdala control? - ✔✔The amygdala is responsible for regulating
aggression and fear.
✔✔What functions does the hypothalamus serve? - ✔✔The hypothalamus regulates
hunger, thirst, body temperature, and sexual behavior.
✔✔Why is the hypothalamus called the reward center? - ✔✔It drives behaviors that lead
to rewards, such as satisfying hunger.
✔✔What is the role of the hippocampus? - ✔✔The hippocampus is involved in forming
new memories and learning.
✔✔What is the cerebrum? - ✔✔The cerebrum is the large part of the brain that governs
conscious thoughts and actions.
