nervous retake

The long, fiber like part of a neuron which the cell sends information to receiving neurons

• axon

• dendrite

• myelin

• Node of Ranvier

This releases neurotransmitters which are sent into the synaptic cleft for receptors on the post-synaptic neuron to receive

• dendrite

• axon terminal

• Scwann cells

• myelin

The part of the neuron that receives messages from adjacent neurons

• axon

• axon terminal

• dendrite

• neuron

This insulating material forms a layer, around the axon of a neuron.  It enables electrical signals to travel down the axon at higher speeds.

• neuron
• myelin sheath
• dendrite
• neurotransmitter

The tiny gap between neurons where nerve impulses are sent from one neuron to another.  It is where communication occurs between an axon and dendrite

• synapse
• axon terminal
• impulse
• myelin

A chemical produced by neurons that carries messages to other neurons

• myelin sheath
• neurotransmitter
• axon
• axon terminal

Excess neurotransmitters in the synapse that goes back into the presynaptic neuron.

• Resting potential
• Reuptake
• Retroactivity
• Repolarization

• Axon Terminal Button

• Neurotransmitters

• Dendrite

• Synapse

What chemical is activated by the action potential in the presynaptic neuron that causes the vesicles containing neurotranmitters to move toward the synaptic cleft?

• calcium

• potassium

• sodium

• phosphorus

Which ions are involved in an action potential?

• Na; Cl
• Na; K
• K; Cl
• Na; Ca
