Which of these definitions have been paired with the correct type of cell?

Blood cells are elongated cells that can contract.

Neurons are cells that conduct electrical impulses.

Epithelial cells are cells that react to stimuli.

Muscle cells are components of blood.

The correct answers is "Neurons are cells that conduct electrical impulses".

Explanation:

Neurons are nerve cells that conduct electrical and chemical impulses, are electrically excitable and serve as communicators to messages. Neurons passes the impulses using specialized structures called synapses. The electrical impulses are known as action potentials, and the chemicals used as impulses are known as neurotransmitters.
