Synapses

A junction at which a neuron meets another cell.

The neuron receiving the nerve impulse.

• Presynaptic

• Postsynaptic

• Inhibition

• Excitation

If positively charged ions flow out of the postsynaptic neuron, or if negatively charged ions enter the neuron, an action potential may be suppressed.

• Presynaptic

• Postsynaptic

• Inhibition

• Excitation

If positively charged ions enter a postsynaptic neuron, an action potential may be produced.

• Presynaptic

• Postsynaptic

• Inhibition

• Excitation

The neuron transmitting the nerve impulse.

• Chemical-gated ion channels causes ions to move across the cell membrane of the postsynaptic cell which produce or suppress action potential.

• Vesicles releases neurotransmitter molecules into the synaptic cleft.

• Neurotransmitter molecules bind to receptor proteins on the postsynaptic cell.

• Neurotransmitter molecules diffuse across the synaptic cleft and interact with the postsynaptic cell.

• Neurotransmitter molecules do not remain in the synaptic cleft indefinitely. It is either reabsorbed by the presynaptic cell or broken down by the enzymes in the synaptic cleft.

• Chemical-gated ion channels causes ions to move across the cell membrane of the postsynaptic cell which produce or suppress action potential.
