5 Written questions

5 Matching questions

  1. metabrotrophic
  2. synaptic proteins involved in exocytosis
  3. excitatory transmission
  4. basilar membrane
  5. excitatory nts
  1. a - synaptic transmission that causes depolarization of the postsynaptic neuron
    - increases the probability that the post synaptic neuron will fire an ap
    - increases amount of neurotransmitter released from prost synaptic neuron by presynaptic facilitation
    - ie. neurmuscular junction
  2. b - synaptobrevin
    - syntaxin
    - SNAP-25
    - synaptotagmin
  3. c - cause an EPSP on the post synaptic neuron
    - glumate is the most common cns nt
    - aspartic acid is also a nt
  4. d - narrow at the base near oval window
    - wide at apex
    - hair cells have cilia will depolorize to different extents in response to frewuency of sound wave
    - 100 times stiffer than the apex
    -moves up an down in response to waves of pressure impinging on the oval window and transmitted through to round window
    - hair cells connect to sensory neurons that live in spiral ganglion inside cochlea
  5. e - slower but long lasting widespread effect

5 Multiple choice questions

  1. - nuclei surrounding thalamus with a common function
    - putamen, globus pallidus, caudate nucleus (aka striatum)
    - substantia nigra
    - subthalamic nuclei
    - a group of deep brain nuclei involved in plannng of voluntary movement including starting & stoping a movement and tone of antigravity muscle
    - lesions cause parkinson's disease
  2. - some cortex areas specialize in decoding texture, shape, and size
  3. - line ventricles with in the brain
  4. - carry out immune function
    - function as phagocytes to remove debris left by dead or degenerate neuron and glia
  5. - ANS
    - innervates all organs, glands, and smooth muscles
    - always active, under the influence of hypothalamus to maitian homeostasis
    - readies body for action, increase heart rate, bp, moves blood to muscles away from viscera
    - fear; neurons in hypothalamus and brain stem activate adrenal glands that secrete adrenalin aka epinephrine

5 True/False questions

  1. parasympathetic ns anatomy- ANS
    - innervates all organs, glands, and smooth muscles
    - always active, under the influence of hypothalamus to maitian homeostasis
    - readies body for action, increase heart rate, bp, moves blood to muscles away from viscera
    - fear; neurons in hypothalamus and brain stem activate adrenal glands that secrete adrenalin aka epinephrine

          

  2. wernicke's area- in secondary cortex
    - when damaged patients cannot understand speech because the sounds or out of order

          

  3. oligodendrocytes- in CNS
    - provide myelin sheaths around axons in the brain & spinal cord

          

  4. parietal lobe- processes sensory information from muscle and skin

          

  5. inhibitory transmission- follows an ap
    - cannot be fired even if there is a transient depolarization
    - due to Na channel inactivation, h gate slow to reopen
    - membrane is negative for h gate to reopen
    - ends when the K channel closes
    - subquent ap cannot be generated until membrane is repolarized
