Question

what is a neuron?
o a stellate cell with two or more long fibrous processes that reach out to other cells
o a short, highly branched cellular extension
o a long tubular process filled with cytoplasm that generates action potentials

Explanation:

A neuron is a specialized cell in the nervous system. It has a cell body (soma) and processes. The processes include dendrites (which receive signals) and axons (which transmit signals). A neuron is a stellate (star - shaped) cell. It has two or more long fibrous processes (dendrites and axons) that reach out to other cells (like other neurons, muscle cells, or gland cells) to communicate.

• The option “a short, highly branched cellular extension” describes a dendrite (a part of a neuron), not the whole neuron.
• The option “a long tubular process filled with cytoplasm that generates action potentials” describes an axon (a part of a neuron), not the whole neuron.

Answer:

a stellate cell with two or more long fibrous processes that reach out to other cells
