Chap 8. Central Nervous System
1. (I know this questions are for chapter 7 problems, I have forgotten to put in Chapter 7 practice questions).
Now indicate whether the following events would stimulate or inhibit skeletal muscle activity.
stimulate
Acetylcholine binds nicotinic receptors on the muscle cell membrane.
inhibit
Calcium is blocked from entering the axon end plate in the presynaptic neuron.
stimulate
Acetylcholine stays in the synaptic cleft for too long.
stimulate
Reuptake pump in presynaptic neuron is inhibited.
inhibit
Sodium channels in the muscle cell membrane are blocked and cannot open
stimulate
Potassium channels in the muscle cell membrane are blocked and cannot open
inhibit
The medication similar to Acetylcholinsterase is taken.
