What is the blood-brain barrier? - ✔✔ANSWER✔✔->>A selective barrier
that protects the brain from harmful substances in the blood.
What is the difference between gray matter and white matter? -
✔✔ANSWER✔✔->>Gray matter contains neuron cell bodies, while white
matter consists of myelinated axons.
,What are the functions of the cerebellum? - ✔✔ANSWER✔✔->>To
coordinate voluntary movements and maintain balance.
What are the 12 pairs of cranial nerves responsible for? - ✔✔ANSWER✔✔-
>>They control various functions including sensory and motor functions of the
head and neck.
What is the function of the spinal cord? - ✔✔ANSWER✔✔->>To transmit
signals between the brain and the rest of the body and to process reflexes.
What is the role of the cerebral hemispheres? - ✔✔ANSWER✔✔->>To
process sensory information, control voluntary movements, and facilitate higher
cognitive functions.
What is the significance of the axon hillock in a neuron? - ✔✔ANSWER✔✔-
>>It is the site where action potentials are initiated.
What is the function of terminal branches in a neuron? - ✔✔ANSWER✔✔-
>>To transmit signals to other neurons or effectors.
What connects the ventricles to the subarachnoid space? - ✔✔ANSWER✔✔-
>>Three apertures: paired lateral apertures and median aperture.
What percentage of brain mass do the cerebral hemispheres account for? -
✔✔ANSWER✔✔->>83% of brain mass.
,What are the surface markings of the cerebral hemispheres? -
✔✔ANSWER✔✔->>Gyri (ridges), sulci (shallow grooves), and fissures (deep
grooves).
Name the five lobes of the cerebral hemispheres. - ✔✔ANSWER✔✔-
>>Frontal, parietal, temporal, occipital, and insula.
What are the three basic regions of each hemisphere? - ✔✔ANSWER✔✔-
>>Cerebral cortex (gray matter), white matter, and basal nuclei.
What functions does the cerebral cortex allow? - ✔✔ANSWER✔✔-
>>Perception, communication, memory, understanding, appreciation, and
initiation of voluntary movements.
What are Brodmann areas? - ✔✔ANSWER✔✔->>Numbered areas of the
cerebral cortex based on differences in thickness and structure of neurons.
What are the three functional areas of the cerebral cortex? -
✔✔ANSWER✔✔->>Motor, sensory, and association areas.
What is the primary motor cortex responsible for? - ✔✔ANSWER✔✔-
>>Controlling skeletal muscles and spatial representation of the body.
What is the motor homunculus? - ✔✔ANSWER✔✔->>A representation of
the body in the primary motor cortex showing areas requiring precise motor
control.
, What is the role of the premotor cortex? - ✔✔ANSWER✔✔->>Helps plan
and coordinate complex movements.
What is Broca's area? - ✔✔ANSWER✔✔->>A motor speech area that directs
muscles involved in speech production.
What is the primary somatosensory cortex? - ✔✔ANSWER✔✔->>Located in
the postcentral gyri of the parietal lobe, it receives general sensory information.
What does the somatosensory association area do? - ✔✔ANSWER✔✔-
>>Integrates and analyzes somatic inputs to interpret sensory information.
Where is the primary visual cortex located? - ✔✔ANSWER✔✔->>On the
extreme posterior tip of the occipital lobe.
What is visual agnosia? - ✔✔ANSWER✔✔->>The inability to recognize or
understand visual stimuli.
What does the primary auditory cortex interpret? - ✔✔ANSWER✔✔-
>>Information from the inner ear as pitch, loudness, and rhythm.
What is the vestibular cortex responsible for? - ✔✔ANSWER✔✔-
>>Conscious awareness of balance and position of the head in space.
Where is the olfactory cortex located? - ✔✔ANSWER✔✔->>On the medial
aspect of the temporal lobes.
