HLSC 2400U Lecture Notes - Lecture 2: Postcentral Gyrus, Resting Potential, Neuromuscular Junction
1. The binding of Ach at the neuromuscular junction results in:
- diffuses across the synaptic cleft and binds to nicotinic acetylcholine
receptors
2. What would be the effect on the resting membrane potential of a drug that increases
the number of open chlorine channels:
-The cell would depolarize causing the RMP to be more positive
3. What are the 4 types of somatosensation:
- Touch, pain, temp, proprioception
4. Of the following pathways, which transmits sensory information to the primary
somatosensory area:
- Conscious relay pathways
5. The pathways for discriminative touch and conscious proprioception uses a 3-neuron
relay. Which one of the following describes the secondary neuron:
a. Second order neuron – brainstem or spinal cord to thalamus
a.i. Second order neuron – cross pons to thalmus via trigeminal lemniscus
6. Neurotransmitters that act _____ are classified as _____, whereas neurotransmitte4rs
that act _____ are classified as ______:
- Act fast, classified as ionotropic
- Act slow, classified as metabotropic
7. Which disorder involves the antibody degeneration of nicotinic acetylcholine
receptors at the neuromuscular junction:
- Myasthenia gravis
8. The following disease is characterized by neuroaxillary tangles and sarillo plaques in
the cerebrum:
- Multiple sclerosis
9. A process whereby a neurons membrane potential becomes more negative than its
resting potential:
- Hyperpolarization
10. Which of the following sensory tracts is responsible for transmitting pain AND
temperature sensation:
- Anterolateral column or spinothalamic tract
