- 1What are the three parts of the hindbrain?Cerebellum
Medulla Oblongata
Pons - 2what three structures make up the dencephalon?Thalamus
Hypothalamus
Epithalamus - 3Which structure is responsible for the production of melatonin?the Pineal gland
- 4Which cells produce cerebrospinal fluid?Ependymal cells
- 5Name the 5 types of glial cellsoligodendrocytes, Schwann cells, ependymal cells, microglia, astrocytes
- 6what was previously believed to be necessary for cognition?neocortex
- 7how was it proved that the neocortex was not necessary for cognition?birds display signs of cognition but their brains do not have neocortex
- 8name the 3 division of the autonomic nervous systemsympathetic
parasympathetic
enteric - 9which division of the autonomic nervous system is responsible for "rest and digest"?the parasympathetic division
- 10what do oligodendrocytes/Schwann cells do?they form myelin sheaths on: oligodendrocytes in the CNS
Schwann cells in the PNS - 11—R = universal gas constant
T = absolute temperature
z = charge of the ion
F = Faraday constant - 12why is the Goldman equation used instead of the Nernst equation to calculate the membrane potential of a neuronbecause the neuron is permeable to more than one ion at a time
- 13in what situation would you use the Nernst equation rather than the Goldman equation when looking at membrane potentials?when the membrane conductivity for a specific ion has increased
- 14what is the relative membrane permeability for K+ ?pK = 1.0
- 15what is the relative permeability for Na+ ?pNa = 0.05
- 16what is the relative permeability for Cl- ?pCl = 0.45
- 17what is the resting potential of a mammalian neuron?-66mV
- 18what is the net movement of Na+ and K+ during the formation of the resting potential?2K+ into the cell and 3Na+ out of the cell
