Question 1

Which of the following best describes the primary function of neurons in nervous tissue?

Accepted Answer

They respond to stimuli and transmit electrical signals.

Question 2

Where in the human body would you most likely find nervous tissue?

Accepted Answer

In the brain, spinal cord, and nerves.

Question 3

Which cell type in nervous tissue is primarily responsible for supporting, insulating, and protecting neurons?

Accepted Answer

Glial cells (neuroglia)

Question 4

A patient suffers damage to the nervous tissue in their spinal cord. Which of the following functions is most likely to be impaired?

Accepted Answer

Transmission of electrical signals between the brain and body

Question 5

Which structural feature is unique to neurons and allows them to transmit electrical signals over long distances?

Accepted Answer

Long cellular processes called axons and dendrites

Question 6

Which of the following is a correct statement about the excitability of neurons?

Accepted Answer

Neurons are excitable because they respond to stimuli and transmit electrical signals.

Question 7

Which of the following equations best represents the movement of ions during the generation of an action potential in a neuron?

Accepted Answer

$$I = g(V_m - E_{ion})$$

Question 8

A histology slide shows cells with long branching processes and a prominent nucleus. What type of tissue is most likely being observed?

Accepted Answer

Nervous tissue

Question 9

Which of the following best explains why glial cells are essential for nervous tissue function?

Accepted Answer

They support, insulate, and protect neurons.

Question 10

If a neuron loses its ability to respond to stimuli, which property has been compromised?

Accepted Answer

Excitability

Question 11

Which of the following is NOT a location where nervous tissue is typically found?

Accepted Answer

Liver

Question 12

A researcher is studying the transmission of electrical signals in neurons. Which part of the neuron is primarily responsible for carrying signals away from the cell body?

Accepted Answer

Axon

Question 13

Which of the following best describes the role of dendrites in a neuron?

Accepted Answer

They receive incoming signals from other neurons.

Question 14

A patient with multiple sclerosis experiences damage to the myelin sheath produced by glial cells. What is the most likely consequence?

Accepted Answer

Impaired transmission of electrical signals along neurons

Question 15

Which of the following is a distinguishing feature of nervous tissue when viewed under a microscope?

Accepted Answer

Cells with long branching processes and prominent nuclei

Question 16

Which of the following best describes the relationship between neurons and glial cells in nervous tissue?

Accepted Answer

Glial cells support, insulate, and protect neurons.

Question 17

Which of the following formulas can be used to calculate the membrane potential ($$V_m) of a $$neuron using the Nernst equation for a single ion?

Accepted Answer

$$V_m = \frac{RT}{zF} \ln \left( \frac{[ion]_{out}}{[ion]_{in}} \right)$$

Question 18

Which of the following scenarios best illustrates the application of nervous tissue function in daily life?

Accepted Answer

The rapid withdrawal of your hand after touching a hot surface

Question 19

Which of the following statements about nervous tissue is correct?

Accepted Answer

Nervous tissue consists of excitable neurons and non-excitable glial cells.

Question 20

A scientist observes a tissue sample with cells that transmit electrical signals and are supported by smaller cells. Which tissue is being observed?

Accepted Answer

Nervous tissue
