Midterm feedback and Let 7

The questions on the midterm were

• fair

• Not fair

The midterm was

• easy

• somewhat easy

• hard

• somewhat hard

I expect my midterm grade to be

• <60%

• 60-70%

• 70-80%

• >80%

The perikaryon is found

• below the axon hillock of a neuron

• between the telodendria of a neuron

• around the nucleus of a neuron

• above the synaptic vesicles of a neuron

All are types of neurons except

• anaxonic

• bipolar

• quatropolar

• multipolar

The colour difference between white and gray matter is due to

• the presence of white blood cells in white matter

• the production of leukocytes

• the myelin sheath that surrounds axons of white matter

• the higher number of Schwann cells

Many neurons synapse on a common post-synaptic neuron

• divergence

• convergence

• parallel processing

• reverberation

Neuroglia that maintain the blood brain barrier

• microglia

• oligodendrocytes

• astrocytes

• ependymal cells

The blood brain barrier consists of the following 3 layers

• 1) endothelial tissue

  2) basement membrane

  3) astrocyte foot processes

• 1) endothelial tissue

  2) basement membrane

  3) microglia

• 1) endothelial tissue

  2) basement membrane

  3) myelin sheath

• 1) Schwann cells

  2) basement membrane

  3) myelin sheath

The myelinating cells of the CNS and PNS (respectively)

• Schwann cells and oligodendrocytes

• Microglia and Schwann cells

• Oligodendrocytes and Schwann cells

• Astrocytes and Schwann cells
