Timby Chapter 36 Exam Questions And
Answers (Guaranteed A+)
The nervous system is divided into these two anatomic divisions - Answer✔CNS and PNS
Neuron - Answer✔Basic structure of nervous system
Sensory neurons - Answer✔Transmit impulses to CNS
Motor Neurons - Answer✔Transmit impulses from CNS
Dendrites - Answer✔Conduct impulses to the cell body. Afferent
Axons - Answer✔Nerve fiber that conducts impulses away from the cell body. Efferent
Synapses - Answer✔Junctions between the axon of a neuron and the dendrite of another
Neurotransmitters - Answer✔Accomplish the transmission of an impulse from ine neuron to the
next. May inhibit or excite a neuron
Myelin - Answer✔A fatty substance that covers some axons in PNS and CNS.
Myelinated - Answer✔Axons that have myelin, aka white matter or white nerve fibers. Serves as
insulation. Confines electrical conduct without allowing it to scatter.
Unmyelinated - Answer✔Axons that do no5 have myelin. Gray matter or gray nerve fibers.
Neurilema - Answer✔Covers thw myelin sheath in PNS neurons
Nodes of Ranvier - Answer✔Periodic gaps between myelin in the axon.
Saltatory conduct - Answer✔When impulses leap from one node into another in myelinated
axons allowing impulses to be much faster than unmyelinated axons.
The central nervous system is composed of - Answer✔The brain, and spinal cord.
The brain is divided into two parts - Answer✔The cerebrum, the cerebellum and the brain stem.
Corpus callosum - Answer✔A band of white fibers that acts as a bridge for transmitting impulses
between left and right hemisphere of the cerebrum in the brain.
