peripheral nervous system

3

Which term refers to the conscious control of skeletal muscles?

  • somatic nervous system
4

What cells of the nervous system are responsible for anchoring neurons to their blood vessels and controlling the extra cellular fluid concentrations of potassium and neurotransmitters?

Astrocytes

5

What is the first event of an action potential?

  • Sodium ions diffuse rapidly and the membrane depolarizes.
6

Which of these lists the components of a reflex arc in the correct sequence?

  • receptor; afferent neuron; control center; efferent neuron; effector
7

The term central nervous system refers to the:

  • brain and spinal cord
8

Fibers that carry information from the skin, joints, and skeletal muscles to the central nervous system are:

  • somatic sensory
9

Which of these neuroglia cells forms the myelin sheath in the central nervous system:

  • Oligodendrocytes
10

The Schwann cell forms a myelin sheath around the:

  • Axon
11

The neuron processes that normally receive incoming stimuli are called:

  • Dendrites
12

Collections of nerve cell bodies outside the CNS are called:

  • Ganglia
13

The major role of the inter neuron is to:

  • connect motor and sensory neurons in their pathways
14

The two major functional properties of neurons are:

  • irritability and conductivity
15

White matters refers to myelinated fibers in the:

  • CNS
16

Impulse conduction is fastest in neurons that are:

  • Myelinated
17

During the resting state, a neuron is:

  • polarized with sodium ions outside the cell and potassium ions inside the cell
18

Immediately after an action potential is propagated, which one of the following ions rapidly diffuses out of the cell into the tissue fluid:

  • potassium
19

An action potential is caused by an influx of these ions into the cell:

  • sodium
20

Nerve impulse transmissions occurring along myelinated neurons are called:

sodium-potassium pump

21

The diffusion of potassium ions out of a neuron causes it to experience:

  • repolarization
22

Which one of the following is the correct sequence of events that correlates to the sequence of events of a nerve impulse:

  1. the membrane becomes depolarized
  2. sodium channels open and sodium ions diffuse inward
  3. the membrane becomes repolarized
  4. potassium channels open and potassium ions diffuse outward while sodium is actively transported out of the cell
  • 2, 1, 4, 3
23

The gap between two communicating neurons is termed:

  • synaptic cleft
24

The substance that is released at axonal endings to propagate a nervous impulse is called:

  • neurotransmitter
25

Which of the following is the correct sequence in a typical reflex arc:

receptor, afferent neuron, integration center, efferent neuron, effector

26

Muscles and glands are:

  • effectors
27

Which type of reflex involves skeletal muscles:

  • somatic
