There are 3 types of nerve cells. Represented here is the Interneuron.
The photo below is a photo of the Structure of a Synapse along with its parts labeled.
- It’s the structure that permits a neuron to pass an electrical or chemical signal to another neuron or to the target effector cells a synapse, one neuron sends a message to a target neuron—another cell. At a chemical synapse, an action potential triggers the presynaptic neuron to release neurotransmitters. These molecules bind to receptors on the postsynaptic cell and make it more or less likely to fire an action potential.
How a signal is sent from the axon of sending neuron to the dendrite of receiving neuron
- The axon of the sending neuron does not actually touch the dendrite of the receiving neuron. there is a tiny gap between them, the synaptic cleft, the neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron.
How the receiving neuron “determines whether or not to send its own action potential.
- The receiving neuron will determine whether or not to send its own action potential if it sees if it is excitatory or inhibitory. Excitatory is when the stimulates action potential on the receiving neuron and inhibitory is the repress’s action potential on the receiving neuron.
