Neurons control |
Cells of CNS Informations processing and communication astrocytes |
|
|
Astrocytes |
Provide structural matrix supporting neuronal networks. Control extra cellular chemical environment "blood-brain-barrier" |
|
|
Classes of neurons (3) |
Sensory Neurons- specialized to receive information from outside the world
Interneurons - act as bridges between the sensory and motor systems.
Motor Neurons- transmit commands from CNS directly to muscles and glands |
|
|
Dendrites |
Receive signals from adjacent Neurons |
|
|
Axons |
Transmit signals Axon hillock, terminal Myelination Nodes of ranvier |
|
|
Levels |

|
Electrostatic force |
Opposite charges attract + and - |
|
|
Diffusion Force |
Molecules move from areas of high concentration to areas of lower concentration. |
|
|
Metabotropic receptors |
G protein causes ion channel to open and Ions pass through |
|
|
Ionotropic Receptors |
Channel opens and ions pass through after binding to ion channel |
|
