THE BRAIN – 11 2025 QUESTIONS
WITH VERIFIED ANSWERS
nervous system consists of - CORRECT ANSWER>>>>CNS and PNS
CNS includes - CORRECT ANSWER>>>>brain and spinal cord
PNS includes - CORRECT ANSWER>>>>cranial nerves and spinal nerves
subdivisions of the brain - CORRECT ANSWER>>>>cerebrum, cerebellum, brain
stem
neurons - CORRECT ANSWER>>>>cells in the nervous system that conduct
impulses
- cell membrane organelles and cytoplasm
dendrites - CORRECT ANSWER>>>>processes that bring info to the cell body,
often from other neurons
axon - CORRECT ANSWER>>>>process that sends info away from the cell body
main type of neuron in the brain - CORRECT ANSWER>>>>multipolar neuron
multipolar neuron set up - CORRECT ANSWER>>>>many dendrites and single
axon
axons are covered in - CORRECT ANSWER>>>>myelin
myelin is formed by - CORRECT ANSWER>>>>glial cells
myelin provides - CORRECT ANSWER>>>>insulation and increases the
conduction velocity
bare spots (nodes) on axon - CORRECT ANSWER>>>>between areas of myelin
where are there nodes on axons - CORRECT ANSWER>>>>the impulse, caused
by the reversal of polarity across the cell membrane, is faster through myelinated
axons because it can jump from node to node
, the central nervous system begins as - CORRECT ANSWER>>>>a neural tube
crainial end develops three dilations, or primary vescicles at the 4th week of
development - CORRECT ANSWER>>>>prosencephalon, mesencephalon,
rhombencephalon
prosencephalon - CORRECT ANSWER>>>>forebrain
mesencephalon - CORRECT ANSWER>>>>midbrain
rhombencephalon - CORRECT ANSWER>>>>hindbrain
the primary vesicles further specialize into secondary vesicles at the 5th week of
development - CORRECT ANSWER>>>>- prosencephalon gives rise to
telencephalon and diencephalon
- mesencephalon retains the name
- rhombencephalon gives rise to metencephalon and myelencephalon
completed structure of prosecephalon and telencephalon - CORRECT
ANSWER>>>>cerebrum
completed structure of prosecephalon and diencephalon - CORRECT
ANSWER>>>>thalamus, hypothalamus and epithalamus
completed structure of mesencephalon - CORRECT ANSWER>>>>midbrain
completed structure of rhombencephalon and metencephalon - CORRECT
ANSWER>>>>pons and cerebellum
completed structure of rhombencephalon and myelencephalon - CORRECT
ANSWER>>>>medulla oblongata
cerebrum hemispheres - CORRECT ANSWER>>>>- consists of right and left
hemispheres
- hemispheres are partially separated by the longitudinal fissure
- location of conscious thought and complex intellectual function
- comprehension of world
- house centers of reasoning and memories
- awareness of sensory imput and initiate motor activity
- surface is convoluted with gyri and sulci to increase surface areas
