Sensory Physiology Midterm 1If you want to learn more check out What is acylation in chemistry?

  1. Cells of the nervous system

  • Camilo Golgi
  • Believed in the Reticular Theory
  • Traditional ideology that the nervous system was made of a single, non-cellular substance
  • Created a cell-staining system used by himself and Ramony Cajal

  • Santiago Ramón Y Cajal
  • Spanish pathologist who disproved the reticular theory and used Golgi’s staining protocol to show that the nervous system is made of cells

  • Supportive cells = Glial Cells
  1. Oligodendrocytes – secrete myelin protein that wraps around neuronal axons to insulate the AP electrical signal
  • Ranvier nodes: gaps in between myelin coatings where V-G ion channels are found
  • Results in ↑Rm and ↑, so the passive propagation of AP in between Ranvier nodes is increased

  1. Astrocytes – scaffolding cells that positions neurons as well as help them grow and synapse efficiently
  •  Neurons climb along astrocytes during brain development
  • Ast. Concept neurons to capillaries + tissues to nourish them
  • Buffer K+ at synapse to help reduce tie between firing
  • Ast. Update K+
  • Reuptake of other neurotransmitters in synapse

If you want to learn more check out What procedure would you use to separate organelles?

  1. Microglia – lymphocytes that come from the circulatory system to protect neurons from pathogens
  • Police the brain + spinal cord
  • Phagocytose  bacteria + viruses
  1. Excitatory cells – include neurons, muscle cells and potentially astrocytes
  • Neurons propagate (+) current through their axons with V-G ion channels

  • Muscle cells receive electrical signals and contrast

If you want to learn more check out What are the contributions of the chinese in san francisco?

  1. Cellular Neurophysiology

  1. Important equations – mostly prescribe a cell at rest
  • Chemical + electric; work (Wc + We)

Wc – the driving force for an ion to enter or exit the cell based on external and internal concentrationsIf you want to learn more check out What’s anchoring?

                Wc = n R T In (out/in)

We -  The driving force for an ion to enter or exit the cell based on its electrical gradient (balancing overall internal + external (charges) If you want to learn more check out What is mark twain known for?

                We = n z V F

At rest, Wc = We and a Voltage Potential is generated

  • Nernst Equation – gives the equilibrium/ voltage potential generated by a single ion existing in unequal concentrate ion on either side of the membrane, as dictated by Wc + We

Vion =  58/z x log (out/in)      - Derived from Wc = WeDon't forget about the age old question of How are isotopes named?

In this context:

        I = positive charge flow

(+) I = current into cell – Depolarizing

(-) I = current out of cell – Hyperpolarizing

  • Ohm’s Law – relates the voltage of a cell to the current passing through the membrane and the permeability of the membrane

V = ΣI x ΣE x V = I/g       R = 1/g

                        Where R  = resistance of ions flowing across the membrane

        G = conductance, flow of ions generating current across a membrane

  • Golden Katz Hogden Equation – derived from Ohm’s Law and the Nernst Equation where:

Iion = gion (Vm – Vion)

                Driving force   ← different from work

                Such that the voltage calculated is for the membrane when al ions able to cross are considered

        Vm = Vk • gk + Vna • gna + Vcl • gcl

                gk + gna + gcl

  • At rest, K+ is the most permeable ion, so Vm = Uk
  • Gk >>> gNa or gel
  • Vm = Vk • gk / gk → Vm = Vk

  1. Ion Channels – allow passage of ions across membrane

  • Selectivity – only Na+ can flow through an Na+ channel
  • Non-Gated – “Leakage channels, open all the time’
  • Voltage Gated (VG) – open in response to depolarization or hyperpolarization of the membrane
  • Found along the axon + pre-syn membrane
  • Legend Gated (LG) – open in response to binding of a chemical messenger
  • Found at the post-syn membrane (soma + dendrites)
