Q

Myelin Sheath

A
  • Protects the axon
  • If gone, the electricity does’t get to the neurotransmitters
  • MS - multiple sclorosis - destruction of the myelin sheath

Q

All or None

A
  • neurons release the same amout of electricity no matter the size of the stimulus
  • If there is a big stimulus, neurons release electricity more often

Q

Plasticity

A
  • Neurotransmitters are eaten then things are released that other neurons are attracted to
  • other neuron chains take over dead neuron’s jobs

Q

4 Types of Neurons

1) Sensory
2) Interneurons
3) Motor
4) Reflex

A
  1. Sensory - (afferent) - goes through the spinal chord
    • takes info to the brain
  2. Interneurons - neurons in spinal chord and brain
  3. Motor - (efferent) - goes to body from brain
    • sends info to body to react to something
  4. Reflex - goes to spinal chord and straight back

Q

Dopamine

A

A Neurotransmitter

  • Attention and emotions
  • too much = schizophrenia
  • too little = parkinsons
