Neuro unit 1
| Front | What is saltatory conduction? |
| Back | instead of traveling smoothly down the axon, the action potential "jumps" from one node to the next, which makes conduction much faster than in unmyelinated axons |
| Front | What happens in the fourth part of neuronal information flow? |
| Back | neurotransmitters are released at axon terminals (outputs): the AP reaches the axon terminals, triggering the opening of voltage-gated Ca2+ channels, causing vesicles to fuse with the membrane, and neurotransmitters released into the synaptic cleft |
| Front | What is the anatomy of the axon? |
| Back | it starts at the axon hillock and may be covered in myelin sheath, where the myelin is segmented, with gaps (nodes of Ranvier), which allow faster impulse transmission |
