Exam 11: Fundamentals of the Nervous System and Nervous Tissue

Figure 11.1Using Figure 11.1, match the following: -Because all action potentials are alike, how does the brain separate situations that require immediate attention from ordinary "positional" reports?

Large- diameter nerve fibers conduct impulses much faster than small- diameter fibers.

Figure 11.1Using Figure 11.1, match the following: -When information is delivered within the CNS simultaneously by different parts of the neural pathway, the process is called processing.

Figure 11.2Using Figure 11.2, match the following: -Postsynaptic membrane.

Figure 11.1Using Figure 11.1, match the following: -Which neuron is rare?

Figure 11.1Using Figure 11.1, match the following: -Which neuron is common only in dorsal root ganglia of the spinal cord and sensory ganglia of cranial nerves?

The autonomic nervous system is under voluntary control; whereas, the somatic nervous system is involuntary.

Figure 11.1Using Figure 11.1, match the following: -Which pattern of neural processing is important for higher level mental processing such as problem solving?

When a sensory neuron is excited by some form of energy, the resulting graded potential is called a(n) .

What symptoms would a nurse focus on in his or her care of a patient with multiple sclerosis?

Figure 11.2Using Figure 11.2, match the following: -Synaptic cleft.

Which of the following will occur when an excitatory postsynaptic potential (EPSP) is being generated on the dendritic membrane?

Saltatory conduction is made possible by _ .

An impulse from one nerve cell is communicated to another nerve cell via the .

If bacteria invaded the CNS tissue, microglia would migrate to the area to engulf and destroy them.

Bipolar neurons are commonly .

What function is served by the increased axon diameter at the nodes of Ranvier?

Sally, a 5- year- old child, was bitten on the hand by a bat that was later diagnosed with rabies. She was immediately treated after the bite but had to go through a series of more involved treatments after the rabies diagnosis in the bat that bit her. How does the rabies virus get to the brain from a simple hand wound?

Neuroglia found in the CNS that bind axons and blood vessels to each other are called .

Neuroglia that control the chemical environment around neurons by buffering potassium and recapturing neurotransmitters are .
