CNS AND PNS EXAM QUESTIONS AND ANSWERS
Neurons-Answer Main function cell of nervous system. Cells that send and receive
signals.
Neuroglia-Answer Cells that support and protect neurons.
The brain and spinal cord is located where? -Answer The central nervous system.
The peripheral Nervous system consist of? -Answer all neural tissue outside CNS
Cranial Nerves connect to what? -Answer The brain
Spinal nerves attach to what? -Answer The spinal cord
Afferent division - Answer Carries sensory information, from PNS to CNS incoming
Efferent division - Answer Carries motor command, from CNS to PNS outgoing
what is Neural tissue? - Answer tissue that composes the nervous system
What does neural tissue include? - Answer neuron and neuroglia
what are the two different types of nervous cells? - Answer Neuron and Nueroglia
What is the function of Neuron and Neuroglia cells? -Answer Neuron-transmits and
, receives signal, Neuroglia- supports and protects neurons
How is the Nervous system divided? -Answer Central Nervous System and Peripheral
Nervous System
Afferent -Answer Carries sensory information, From PNS sensory receptors to CNS
Efferent -Answer Carries motor commands, From CNS to PNS muscles and glands
Somatic Nervous System -Answer Controls skeletal muscles
Visceral Nervous System - Answer Controls smooth muscle, cardiac muscle and glands
"unconscious control"
Parasympathetic Nervous System - Answer Decrease heart rate "rest and digest"
Sympathetic Nervous System - Answer Increase heart rate "fight or flight"
What is a neuron? - Answer Cells that send and receive signals
Cell body - Answer aka "soma" contains nucleus
Perikyon - Answer In cytoplasm
Neurofibirls - Answer help support organelles in the cell body
Centrioles - involved with mitotis and not in cell body, cell cannot divide and replicate
