What are the structure and function of neurons?
Understand the Problem
The question refers to the structure and function of neurons, their components such as the myelin sheath and Schwann cells, and their role in the nervous system. This indicates a focus on biological concepts related to human physiology.
Answer
Neurons have dendrites, cell body, and axon.
Neurons consist of dendrites, a cell body, and an axon. They carry messages via electrical impulses. Myelin sheaths and nodes of Ranvier enhance impulse speed.
Answer for screen readers
Neurons consist of dendrites, a cell body, and an axon. They carry messages via electrical impulses. Myelin sheaths and nodes of Ranvier enhance impulse speed.
More Information
Neurons use electrical and chemical signals to communicate rapidly. The myelin sheath insulates axons, improving signal transmission efficiency.
Tips
A common mistake is confusing the parts of a neuron with its functions. Ensure clarity in each part's role in signal transmission.
