Nodes of Ranvier | Openings of the Myelin Sheath |
Terminal Buttons | Holds/releases neurotransmitters in synapse/synapticgap. |
Medulla | controls automated processes like breathing, blood pressure, and heart rate. |
Pons | connects the brain and the spinal cord; involved in regulating brain activity during sleep. |
Cerebellum | controls our balance, coordination, movement, and motor skills, and it is thought to be important in processing some types of memory. |
Synapase | space between dendrite and terminal buttons |
Substantia Nigra | where dopamine is produced; involved in control of movement. |
Ventral tegmental area (VTA) | where dopamine is produced; associated with mood, reward, and addiction. |
