Diversity of neurons Flashcards
What is the function of motor neurons?
Responsible for triggering movement by conveying signals to muscles
Motor neurons cause muscular contractions.
Describe the structure of motor neurons.
Large with long axons that reach out to muscles
Long axons allow signals to be conveyed across greater distances.
What do sensory neurons do?
Convey information from the sense organs to the brain
Examples include signals from the eyes, ears, and skin.
How do sensory neurons vary in structure?
They have varying shapes depending on the type of stimulus they detect
This specialization allows them to be tailored for different sensory information.
What is the primary function of interneurons?
Process information from other neurons and integrate it
Interneurons pass the integrated information along to other neurons.
What is notable about the structure of interneurons?
They have shorter axons and form complex networks
Their structure allows them to perform intricate functions such as cognition and memory.
What are key characteristics of larger neurons?
More complex inputs and outputs, cover greater distances, convey information more rapidly
Larger neurons facilitate faster communication.
Where are smaller neurons typically found and what is their role?
Typically found in the brain, performing localized tasks
Smaller neurons contribute to intricate neural circuits.
What is the axon length range for motor and sensory neurons?
Can be a meter or more in length
This allows signals to travel long distances.
What characterizes the axons of interneurons?
They may have much shorter axons
This reflects their role in local information processing.
What do intricate networks of interneurons contribute to?
The brain’s complex functions, including thought, learning, and emotion
Interneurons form the backbone of cognitive processes.
Why is there a large variety in neuron shape, size, and function?
To efficiently process and transmit information across vast distances and intricate pathways
This diversity is essential for the nervous system’s functionality.
