PAPER 2026 QUESTIONS WITH SOLUTIONS
GRADED A+
◉Temporal Lobes. Answer: Regions of cerebral cortex below
parietal lobes and in front of occipital lobes
Important for processing auditory info and for perceiving objects
and faces
◉Occipital Lobes. Answer: Regions of cerebral cortex at back of
brain
Important for vision
◉Parietal Lobes. Answer: Regions of cerebral cortex in front of
occipital lobes and behind frontal lobes
Important for sense of touch and for picturing layout of spaces in an
environment
,"Homunculus"
◉Frontal Lobes. Answer: Regions of cerebral cortex at front of brain
Important for movement and complex processes
-Rational thought, attention, social processes
◉Neuron Communication. Answer: Transmission~ When enough
stimulation in presynaptic neuron to create action potential travels
quickly down myelinated axon to terminal button
Reception~ Action potential causes neurotransmitters to be
released from terminal buttons at end of the axon.
Neurotransmitters cross synapse and fit into receptors in dendrites
of postsynaptic neuron
Integration~ Each neurotransmitter has either excitatory or
inhibitory effects on post synaptic neuron that's summed up in cell
body. If enough action it'll lead to another action potential
◉Neurons. Answer: Basic unit of nervous system; cells that receive,
integrate, and transmit info in nervous system
, Operate through electrical impulses, communicate with other
neurons through chemical signals, and for neural networks
-Can't fire only a little bit, either fires or doesn't at all
◉Cell Body. Answer: Part of neuron where info from thousands of
other neurons are collected and integrated
◉Axon. Answer: Long, narrow outgrowth of neuron that enables it
to transmit info to other neurons
◉Myelin Sheath. Answer: Fatty layer that insulates the axon
◉Dendrites. Answer: Branchlike extensions of neuron with
receptors that detect info from other neurons
◉Synapse. Answer: Site of communication between neurons
through neurotransmitters
-Don't actually touch
◉Action Potential. Answer: Neutral impulses that travel along axon
then causes release of neurotransmitters into synapse
