How the nervous system works
Öykü Penceresi Metni
- Slayt: 4
- It all starts with these branch-like figures called dendrites! Dendrites receive signals from the neurons and transfer them to the cell body.
- The cell body is that circular shape you see in the middle of that figure! They produce energy that fuels the neuron's activity. From the cell body, the message tranfers to the axon.
- Slayt: 5
- This is the axon! The axon simply transmits messages the messages to the other side of the neuron. These are protected by a white, fatty substance called the myelin. The myelin also helps speed up the work of the neurons.
- Slayt: 6
- This right here is a neuron! Neurons are the fundamental units of the nervous system. These cells transmit information. Now, let's learn more about the message's journey from neurons to other cells!
- Lastly, we have the axon terminals! They are joined to the neuron by a synapse. Axon terminals release the neurotransmitters of the cell. Neurotransmitters are chemicals that send messages across the synapses. And just like that, the message traveled from a neuron to another cell !
