True

47
Q

False, they’re always open

50
Q

Q

T/F: Depolarization is dependent on ligand-gated channels

A

False, they’re dependent on voltage gated channels

52
Q

Which kind of drug blocks voltage-gated channels?

A

Anesthetics, analgesics only changes how pain is interpreted

53
Q

T/F: Spatial or temporal summation allows for graded potentials to be added together so that the post-synaptic neuron can reach threshold

A

True

54
Q

T/F: Pre-synaptic neurons that produce IPSPs close to the axon hillock will cause a greater chance of an action potential for that neuron

A

False

55
Q

T/F: Split brain patients can tell their left from their right

A

True

56
Q

T/F: Neurons carrying pain from the tip of the tongue will synapse on the trigeminal ganglion

A

False, because trigeminal ganglion is what starts the pathway. its not really going to synapse onto another neuron bcs its alr so close to the brain

57
Q

T/F: Spinal nerves are motor, sensory or both

A

False, because they are BOTH

58
Q

T/F: Cranial nerves are motor, sensory or both

A

True

59
Q

If you study for short periods of time everyday for a test on Friday, are you testing your short-term memory or long-term memory

A

Short-term

60
Q

T/F: If you were to study for 5 days straight then be tested on that material a week later, you are testing your long-term memory

A

True

61
Q

T/F: Sensory neurons for general sensation have dendrites

A

False, they’re pseudounipolar neurons that only have an axon

62
Q

T/F: The CNS is made up of brain and spinal cord

A

True

63
Q

What neuron in the sensory neuron pathway crosses the midline?

A

2nd order neuron

64

True

83
Q

T/F: The involuntary motor control is sensory
