Types of Neurons

Question 1

What is the function of motor neurons?

Answer 1

Trigger muscle movements by conveying signals

Motor neurons transmit signals from the brain or spinal cord to muscles.

Question 2

What is the structure of motor neurons?

Answer 2

Large neurons with long axons

This structure enables them to send signals over long distances.

Question 3

What do sensory neurons do?

Answer 3

Relay sensory information from organs to the brain

Examples include information from the eyes and skin.

Question 4

How do sensory neurons vary in structure?

Answer 4

They vary in shape depending on the sensory input

This allows for specialization in processing different stimuli like light, sound, and touch.

Question 5

What is the primary function of interneurons?

Answer 5

Process and integrate information between neurons in the brain

Interneurons are involved in complex cognitive functions such as thought and decision-making.

Question 6

Describe the structure of interneurons.

Answer 6

Shorter axons forming intricate networks

This allows them to process localized information.

Question 7

What tasks do larger neurons typically handle?

Answer 7

Complex tasks, convey information over long distances, and transmit information quickly

Larger neurons are crucial for rapid communication in the nervous system.

Question 8

What is the role of smaller neurons?

Answer 8

Involved in localized, intricate processing in the brain

Smaller neurons typically handle specific, localized tasks.

Question 9

How does neuron diversity contribute to the brain’s function?

Answer 9

Enables efficient processing and transmission of information

Diversity in neuron structure (size, shape, axon length) is essential for the nervous system’s functionality.

Question 10

What role do interneuron networks play in the brain?

Answer 10

Critical for higher-level functions such as cognition, learning, and emotion

Interneurons are vital for complex brain activities.
