How is neurons similar to a blood cell

A blood cell carries Hemoglobin. A neuron doesn't have hemoglobin, and uses other proteins.

Explanation:

Red blood cells carry a specific type of protein, called hemoglobin, which is able to bind oxygen and release it in other tissues. A nerve cell doesn't have this protein because it doesn't need to bind oxygen. Instead, the nerve cell uses other proteins that help it transmit signals to other cells.

Neurons are surrounded by a cell membrane.
