PAPER SOLVED QUESTIONS WITH
ACCURATE ANSWERS STUDY PACK
●● Depolarized cell
Answer: Positively charged, Na+ enters cell
●● Hyperpolarized cell
Answer: When a cell is more negative than RMP
●● Ion channels
Answer: A transmembrane protein channel that allows a specific ion to
diffuse across the membrane down its concentration or electrochemical
gradient.
●● Voltage-gated channels
Answer: Open or close in response to changes in membrane potential.
Most important
●● Ligand-gated ion channel
Answer: Type of membrane receptor that has a region that can act as a
"gate" when the receptor changes shape.
,●● Mechanically-gated channels
Answer: Open in response to physical deformation of the receptor
●● Chemoreceptors
Answer: Chemical sensors in the brain and blood vessels that identify
changing levels of oxygen and carbon dioxide
●● Thermoreceptors
Answer: Respond to changes in temperature
●● Mechanoreceptors
Answer: Respond to touch, pressure, vibration, stretch, and itch
●● Photoreceptors
Answer: Rods and cones
●● Synapse
Answer: The junction between the axon tip of the sending neuron and
the dendrite or cell body of the receiving neuron
●● saltatroy conduction
Answer: process by which an electrical signal jumps across the nodes of
Ranvier to travel down the axon
, ●● Meninges
Answer: dura mater, arachnoid mater, pia mater
●● Leptomeninges
Answer: arachnoid and pia mater
●● Parietal lobe
Answer: receives sensory input for touch and body position
●● Temporal lobe
Answer: A region of the cerebral cortex responsible for hearing and
language.
●● Frontal lobe
Answer: A region of the cerebral cortex that has specialized areas for
movement, abstract thinking, planning, memory, and judgement
●● Occipital lobe
Answer: A region of the cerebral cortex that processes visual
information
●● Dorsal root
