Neuron and Glia 17:48 Nissl Stai Show a clump of neuron cells that allows to distinguish neurons and glia from  one another and also enable histologists to study the arrangement of neurons  in different part of the brain Golgi Stain Show a central region that contains the cell nucleus (soma) and thin tubes  that radiates away from the soma Soma + neurites (thin tubes) Neuritis = axons and dendrites Axoplasmic Transport Anterograde transport = from soma to the terminal Retrograde transport = from terminal to the soma Glia – supports neuronal functions Astrocytes cells o Most numerous o Fill spaces between neurons Influence neurite growth o Regulate extracellular chemical content Ex. Remove many neurotransmitters from the synaptic cleft Myelinating glia - insulation o Oligodendroglial cells Found in CNS o Schwann cells Found in PNS

The Neuronal Membrane at Rest 17:48 - Impulse is sent from neuron to neuron

The Neuronal Membrane at Rest 17:48 - When a man step on a sharp object, the information is being sent to the brain  by the sensory neuron. But before the information gets to the brain, the reflection  happens before. So what is reflection? - Learn the structure of the protein - Selectivity is in the loop of the membrane channel - Ions are moved by these forces concentration gradient electrical gradient - the membrane is always negatively charge at rest ~ -65 mV is to keep the membrane at rest positive changes outside and negative changes inside o when a channel that allows the positive charges to move across the  membrane is inserted. It makes the outside more positive than inside thus
