Front

What is the correct sequence of the reflex arc?

Back

stimulus > afferent neuron > integration center > effector neuron > effector

Front

What is the main difference between a reflex and a normal nervous system response?

Back

Reflexes don't involve the brain.

Front

Which part of the neuron receives impulses first?

Back

Dendrite.

Front

What structure resets the potential of a neuron after an action potential?

Back

Sodium Potassium Pump.

Front

What cell type lines the cavities of the brain and spinal cord and circulates CSF with cilia?

Back

Ependymal cells.

Front

What is the function of the sodium-potassium pump?

Back

Front

What is the role of dendrites in a neuron?

Back

To receive signals from other neurons.

Front

What is an action potential?

Back

A rapid change in membrane potential that occurs when a neuron sends a signal.

Front

What is the function of myelin sheath?

Back

To insulate axons and increase the speed of nerve impulse transmission.

Front

What are neurotransmitters?

Back

Chemical messengers that transmit signals across a synapse from one neuron to another.
