Question: 1 / 490

What is the basic structure that contains the nucleus in a neuron?

Axon

Dendrite

Cell body

The basic structure that contains the nucleus in a neuron is the cell body. The cell body, also known as the soma, is the central part of a neuron and is responsible for maintaining the life of the neuron. It contains the nucleus, which houses the cell's genetic material and is involved in the regulation of gene expression and cellular functions.

The cell body also integrates incoming signals from other neurons through its dendrites and is crucial for processing information before transmitting electrical signals down the axon. The axon is responsible for carrying these signals away from the cell body to other neurons or target cells, while dendrites are structures that receive signals from other neurons. The synapse is the junction between two neurons where communication occurs but does not contain the nucleus.
