BIO 30 NERVOUS SYSTEM
COMPREHENSIVE TEST PAPER QUESTIONS
AND SOLUTIONS VERIFIED PREPARATION
MATERIAL
●● Importance of nervous system
Answer: Responsible for coordinating hundreds of tasks including
breathing rate, light, temperature/odor reception, blinking,
itches/scratching, and memories.
●● Central nervous system
Answer: brain and spinal cord
●● Peripheral nervous system
Answer: the sensory and motor neurons that connect the central nervous
system to the rest of the body
●● Somatic nervous system
Answer: A subdivision of the peripheral nervous system. Enables
voluntary actions to be undertaken due to its control of skeletal muscles
●● Autonomic nervous system
,Answer: A subdivision of the peripheral nervous system. Controls
involuntary activity of visceral muscles and internal organs and glands.
●● Sensory neurons
Answer: neurons that carry incoming information from the sensory
receptors to the brain and spinal cord
●● motor neurons
Answer: neurons that carry outgoing information from the brain and
spinal cord to the muscles and glands
●● Interneurons
Answer: Central nervous system neurons that internally communicate
and intervene between the sensory inputs and motor outputs
●● Sympathetic nervous system
Answer: fight or flight
●● Parasympathetic nervous system
Answer: rest and digest and reverts the effects of the Sympathetic
nervous system
●● Glial cells
, Answer: cells in the nervous system that support, nourish, and protect
neurons
●● Dendrites
Answer: Branchlike parts of a neuron that are specialized to receive
information.
●● Cell body
Answer: contains nucleus
●● Axon
Answer: the extension of a neuron, ending in branching terminal fibres,
through messages, pass to other neurons or to muscles or glands
●● Axon Hillock
Answer: the cone-shaped area on the cell body from which the axon
originates and first signal begins
●● End Plates/ Terminal Branches
Answer: Branched endings of an axon that transmit messages to other
neurons
●● Nodes of Ranvier
