Quiz for Nerve Tissue

 << Go to card set details


Question 1
Multiple-choice

Neurons

Select the best answer

Composed of a cell body, dendrites, and an axon
*we are born with all the neurons we'll ever have & some are dormat

1)Integrate and interperet stimuli
2) Direct an appropriate response

Carries impulses from the CNS to the involuntary muscles and all glands.
*Cardic/Smooth muscles

One processes that divides into 2 branches; 1 goes to the PNS & 1 goes to the CNS

Question 2
Multiple-choice

What do Glial cells do?

Select the best answer

1)Provide structural support
2)nourishment for the neurons

1)Integrate and interperet stimuli
2) Direct an appropriate response

One process emerges from each pole of the cell body

1 Central nervous system--CNS
2 peripheral nervous system--PNS

Question 3
Multiple-choice

Direction of an impulse transmission between 2 neurons?

Select the best answer

transmit sensations from PNS to CNS

Axon, dendrite, neurotransmitter

1 Neurons
2 Glial

Axon* Dendrite

Question 4
Multiple-choice

Perikaryon

Select the best answer

1 Central nervous system--CNS
2 peripheral nervous system--PNS

Conduct impulses away from the cell body
*one way flow of info

The nerve cell body. Contains the nucleus and organelles

1)Provide structural support
2)nourishment for the neurons

Question 5
Multiple-choice

Schwann Cells

Select the best answer

carries impulses from the CNS to the voluntary muscles
*ex. skeletal muscles of hand

Production of Myelin sheath
*responsible for increasing the speed of conduction of an impulse along a neuron

Contained in synaptic vesiscles in axon only. This ensures that nerve transmission is in one direction only.

Nerve processes that carry info from the PNS in muscles and glands to the CNS
-To CNS

Question 6
Multiple-choice

Cytoplasmic extensions includes what?

Select the best answer

Phagocytic scavenger cell

-70mV

Acetylcholine
Serotonin
Dopamine
Norepinephrine

1) Dendrites
2) Axon

Question 7
Multiple-choice

Oligodendrocyte-CNS

Select the best answer

Junctions between 2 neurons or between a neuron and its effector (muscle or gland)

Myelin, which forms Myelin Sheath on the outside of an axon.

produces myelin
Myelin sheath increases the speed of electrical conduction

carries impulses from the CNS to the voluntary muscles
*ex. skeletal muscles of hand

Question 8
Multiple-choice

4 types of Glial Cells

Select the best answer

Have many dendrites arising from the cell body
*Most

1 Astrocyte
2 Microglia
3 Oligodendrocyte
4 Schwann cell

1 Central nervous system--CNS
2 peripheral nervous system--PNS

receive stimuli and conduct impulses toward the cell body

Question 9
Multiple-choice

What are the cells of the nervous system?

Select the best answer

Depolarization

1 Neurons
2 Glial

Acetylcholine
Serotonin
Dopamine
Norepinephrine

Nodes of Ranvier

Question 10
Multiple-choice

Bipolar

Select the best answer

1 somatic motor neurons
2 autonomic motor neurons

One process emerges from each pole of the cell body

1 Central nervous system--CNS
2 peripheral nervous system--PNS

Myelin, which forms Myelin Sheath on the outside of an axon.
