Introduction Definition How neurotransmission occurs Types of neurotransmission Neurotransmitters Types of neurotransmitters Impairment in neurotransmission

Scene 3

Henry  Hallett  Dale was the man who discovered acetylcholine. Acetylcholine is one of the most abundant neurotransmitters in the brain. T hat’s how we came to know about neurotransmission.

Scene 4

The human brain has billions of neurons and these neurons communicate with each other through chemical signals. The transfer of information from one neuron to another through chemical signals is called neurotransmission.

Scene 5

Neuron is not the only target in neurotransmission. The  target can be another cell, muscle or any other neuron.

Scene 6

There are three main parts of a neuron; Axon: away from the cell body. Dendrite: close to the cell body. Cell body

Scene 7

Neurotransmission is the interaction between these parts. The neurotransmitter is released and interacts with the dendrites of another neuron.

Scene 8

They are produced in the  ribosomes  of the  presypnatic  neuron. When an action potential arrives at the pre- sypnaptic  terminal, there is the entry of the calcium ions in pre- sypnatic  neurons.

Scene 9

After calcium ions entry into the cell, synaptic vesicles merge with pre-synaptic membrane. Neurotransmitter is released into the synaptic cleft.
