Brain Lobes – what they are used for and where are they located |
Frontal Lobe -under your forehead -center of reasoning Parietal Lobe - top of your head - receives senses from the skin Temporal Lobe - sides of your head above your ears - hearing, perception, speech Occipital lobe - back of your head - receives input from your eyes Occipital Lobe |
|
|
Axon |
conducts electrical impulses known as action potentials away from the nerve cell body |
|
|
synapse |
small gap separating neurons |
|
|
how a neuron works |
A message comes from the dendrites from another neuron and is processed in the cell body of the neuron. The message can then move through the long axon and further toward the axon terminal, to the synapses and finally to another cell. When a message moves through the axon it’s called action potential. |
|
