Document Summary

Involves understanding the physical brain and it"s effects on your behaviour. Your interactions with the environment, your movement, your thoughts, perceptions, and behavior- all products of your functioning brain. Transmits information to other neurons, muscles, and glands through terminal endings. Receive info from other neurons, transits to cell body. Layer of fatty material that helps speed up the transmission of signals/information to travel faster along the axon , gaps in myelin sheath are . Junction between one neuron"s axon and another neuron(neurotransmitters cross the synapse) ; key part in . They provide nutrients/insulating myelin, guide neural connections and mop up ions/neurotransmitters ; also play a role in learning/thinking(information transmission/memory) Interneurons - between sensory input and motor output ; most complex tasks and more interneurons- there"s billions. In the neurons chemistry to electricity process, ions(electrically charged atoms) are exchanged. Extracellular fluid(outside of cell) has positively charged sodium ions.
