ASSESSEMENT QUESTIONS AND
ANSWERS (VERIFIED) 2025.
two parts of nervous system - Answer central nervous system and peripheral nervous system
central nervous system - Answer brain and spinal cord
peripheral nervous system - Answer A division of the nervous system consisting of all nerves
that are not part of the brain or spinal cord.
-nerves arising from brain and spinal cord. cranial and spinal nerves
Role of Central Nervous System - Answer collection of information integration and analysis and
processing the info
peripheral nervous system role - Answer Communication lines, link all parts of the body by
carrying sensory input to the CNS and then carrying the instructions for response back to the
glands and muscles and central nervous system
Peripheral Nervous System (PNS) - Answer receptors and effectors
receptors - Answer parts of the cell membrane that receive the neurotransmitter and initiate
or prevent a new electric signal
-receive signals of stimuli from environment
-they need to be converted into electrical signal so that brain and spinal cord understand it
-role: conversion of stimulation
-this conversion is called action potential
-classified in 3 groups: special sense, visceral sensory, somatic sensory
-special: vision, sense of smell, taste, balance, and hearing. detected with eye ear nose etc
(special sense organs)
-somatic: arising from skin i.e touch pressure pain and temperature. also skeletal muscles (to
, action potential - Answer the change in electrical potential associated with the passage of an
impulse along the membrane of a muscle cell or nerve cell.
effectors - Answer -produces a response e.g.muscle contracts to move hand away from
stimulus or gland squeezes and releases hormone into blood.
-acting involuntarily
peripheral nerves groups - Answer -carry signal to brain and spinal cord for information
processing
-either sensory nerves or fibers or ascending fibers or nerves
cell body of neuron - Answer where info processing takes place in brain and spinal cord
motor division (efferent) - Answer nerve fibers that carry impulses away from the CNS or brain
and spinal cord
autonomic nervous system - Answer A subdivision of the peripheral nervous system. Controls
involuntary activity of visceral muscles and internal organs and glands.
-sympathetic and parasympathetic
(effectors respond to this signal)
cells in neural tissue - Answer neurons and neuroglia
-neurons: responsible for the transfer and processing of information in the nervous system.
consists of soma, axon, and dendrites
-neuroglia: supporting the cells and protecting the neuron. they do not process info. they
provide nutrients, eliminate waste, etc
dendrites - Answer a neuron's bushy, branching extensions that receive messages and conduct
impulses toward the cell body
axon - Answer the extension of a neuron, ending in branching terminal fibers, through which
messages pass to other neurons or to muscles or glands
-at end usually splits and develops bulges called terminal button (where neurotransmitters or
