Dr. Vazquez is examining a cell from the nervous system of an animal. He notices that at one end of the cell body is a long, fibrous strand of tissue. He immediately recognizes this as an axon that is responsible for

• carrying signals away from the cell body

• receiving signals from other cells and carrying them toward the cell body.

• determining the speed at which an action potential will travel

• determining whether the cell inhibits or excites neighboring neurons

Which of the following is regulated by the autonomic nervous system

• Breathing

• Kicking a soccer ball

• Balancing on one foot

• Raising your hand

Neurotransmitters are ______________ that travel across the ______________ to another cell.

• electrical signals; receptors

• electrical signals; synapse

• chemicals; receptors

• chemicals; synapse

• Dendrite

• Axon

• Cell Body

• Myelin Sheath
