• Calcium Channels

The part of the neuron that receives information/ messages from another neuron is called the _________.

• Axon terminal

• Dendrite

• Axon

• Myelin sheath

The ________ is the part of the neuron that carries the neural message away from the cell body towards another receiving neuron.

• Dendrites

• Nucleus

• Receptors

• Axon

_____ is the message-receiving neuron while _____ is the message-sending neuron.

• Post-synaptic neuron; pre-synaptic neuron

• Pre-synaptic neuron; post-synaptic neuron
