◍ What is the condition characterized by cognitive impairment due to vascular
issues?.
Answer: Vascular Cognitive Impairment (VCI)
◍ What is the function of the parietal lobes?.
Answer: To process sensory information and integrate sensory input.
◍ What is the term for the movement of molecules from areas of high
concentration to areas of low concentration?.
Answer: Diffusion
◍ What is the primary function of the somatic nervous system?.
Answer: The somatic nervous system innervates the sensory organs and
skeletal muscles.
◍ What happens when neurotransmitter molecules bind to receptors on the
postsynaptic cell?.
, Answer: They cause a postsynaptic potential (PSP)
◍ What is the role of neurotransmitter receptors in the postsynaptic
membrane?.
Answer: They bind neurotransmitter molecules and initiate postsynaptic
potentials
◍ What is the main characteristic of apraxia?.
Answer: Difficulty in performing tasks or movements when asked, despite
having the desire and physical ability.
◍ What is the role of the cerebellum?.
Answer: To coordinate voluntary movements and maintain posture and
balance.
◍ What is meant by 'selectivity' in ion channels?.
Answer: It refers to the specific type of ion that the channel allows to pass
through.
◍ What does 'caudal' refer to?.
Answer: 'Caudal' refers to the direction toward the tail.
◍ What are gliomas?.
Answer: Neoplasms (tumors) that can arise from any type of glial cell.
◍ VII
I. Vestibulocochlear (sensory or motor).
Answer: Sensory
◍ What are the three main categories of white matter connections in the
brain?.
Answer: Projection fibers, commissural fibers, and association fibers.
◍ What are voltage-gated ion channels?.
Answer: Channels that open and close depending on the membrane
potential.
◍ In which system are unipolar neurons primarily found?.
Answer: The peripheral components of the somatosensory system.
,◍ What is an action potential?.
Answer: A rapid change in membrane potential that propagates along the
axon.
◍ What is the effect of large polar molecules on ion distribution across the
membrane?.
Answer: They can create concentration gradients by attracting or repelling
ions, affecting their distribution.
◍ What is the significance of the cephalic flexure in human anatomy?.
Answer: The cephalic flexure indicates a 90-degree rotation of the neuraxis
with respect to the environment.
◍ What is a fiber tract in the CNS?.
Answer: A fiber tract is a bundle of myelinated axons that connects two
regions of the CNS.
◍ What are neurons also known as?.
Answer: Nerve cells.
◍ Olfactory function.
Answer: Smell
◍ What is the relationship between neurodegenerative diseases and misfolded
proteins?.
Answer: All neurodegenerative diseases involve misfolded proteins and
abnormal protein deposits in the brain.
◍ What is the primary role of the hippocampus?.
Answer: To facilitate memory formation and spatial navigation.
◍ Define 'distal'..
Answer: Farther from the point of origin or trunk.
◍ Define the axial plane..
Answer: A horizontal plane that divides the brain into superior and inferior
portions.
, ◍ What are the two main types of neurons based on their location?.
Answer: Central nervous system (CNS) neurons and peripheral nervous
system (PNS) neurons.
◍ What is the significance of understanding molecular pathologies in
neurodegenerative diseases?.
Answer: It is important for developing disease-modifying interventions.
◍ How do neurodegenerative diseases affect the nervous system?.
Answer: They selectively target specific anatomical regions or functional
systems, leading to distinct clinical syndromes.
◍ What distinguishes Alzheimer's disease from other neurodegenerative
diseases?.
Answer: It primarily involves cognitive decline and progresses to dementia.
◍ What is the neuro-muscular junction?.
Answer: The synapse between efferent neurons and muscle cells.
◍ Abducens nerve (number).
Answer: VI.
◍ Who is the author of 'Functional Neuroanatomy and Clinical
Neuroscience'?.
Answer: Suzan Uysal.
◍ V. Trigeminal (sensory or motor).
Answer: Both
◍ How do neurodegenerative diseases typically manifest?.
Answer: As a change in neurological function that begins insidiously after a
long period of normal function.
◍ What is the role of neuropsychological assessments in clinical practice?.
Answer: To diagnose cognitive and behavioral disorders and guide treatment
recommendations.
◍ What are the three primary vesicles in early brain development?.
Answer: Prosencephalon (forebrain), mesencephalon (midbrain), and
