Document Summary

Space between the axon and cell body. Impulse goes from the presynaptic neuron to the postsynaptic neuron. Lock and key transmission a presynaptic neurotransmitter can only connect to a postsynaptic receptor that has the same as that particular molecule. Much like a key only fits into the lock it was made for. After transmission the neurotransmitters undergo a chemical breakdown into chemical components or they"re taken back into the presynaptic cell. Morphine mimics natural endorphins, which give you the high" feeling. Stem cells (embryonic cells) have the ability to become whatever type of cell is most needed by the body. Sympathetic flight or fight (adrenaline, increased blood flow) Parasympathetic rest and digest (salivation, digestion) The brain is not always involved in movements, such as spinal reflex. An example of this is when you burn your hand and your body very quickly pulls it away from the source of the burn.
