In which part of a neuron is the nucleus located?
Solution
Correct Answer: Option C
- The nucleus of a neuron is located in the cell body, also known as the soma.
- The cell body is the central part of the neuron that contains the nucleus and other organelles essential for the neuron's metabolic activities.
- It plays a crucial role in maintaining the neuron's health and function by producing proteins and other molecules needed for cell repair and growth.
- The dendrites are branched extensions from the cell body that receive signals from other neurons, while the axon terminal is the endpoint of the axon where neurotransmitters are released to communicate with other neurons or target cells.
- The myelin sheath is a fatty layer that surrounds the axon to increase the speed of electrical signal transmission but does not contain the nucleus.
Therefore, the correct answer is the cell body, as it houses the nucleus and supports the neuron's vital functions.
