11) Imagine you were to use curare to block nicotinic acetylcholine-gated receptors. Would there be any effect on the activity in either the monosynaptic or polysynaptic components of the stretch reflex when the muscle is stretched, as compared to when the muscle is stretched without curare present? (In answering this question, just consider the components in the stretch reflex, including the muscle) (4 points) a) No, curare would not have any effect on the components in either the monosynaptic or polysynaptic stretch reflex circuit. b) Yes, curare would cause a decrease in the activity of one or more components in the monosynaptic stretch reflex circuit(s). c) Yes, curare would cause a decrease in the activity of one or more components in the polysynaptic stretch reflex circuit(s). d) Yes, curare would cause a decrease in the activity of one or more components in both stretch reflex circuit(s). e) Yes, curare would cause an increase in the activity of one or more components in the monosynaptic stretch reflex circuit(s). f) Yes, curare would cause an increase in the activity of one or more components in the polysynaptic stretch reflex circuit(s). g) Yes, curare would cause an increase in the activity of one or more components in both stretch reflex circuit(s).

Question
Transcribed Image Text:11) Imagine you were to use curare to block nicotinic acetylcholine-gated receptors. Would there
be any effect on the activity in either the monosynaptic or polysynaptic components of the stretch
reflex when the muscle is stretched, as compared to when the muscle is stretched without curare
present? (In answering this question, just consider the components in the stretch reflex, including
the muscle) (4 points)
a) No, curare would not have any effect on the components in either the monosynaptic or
polysynaptic stretch reflex circuit.
b) Yes, curare would cause a decrease in the activity of one or more components in the
monosynaptic stretch reflex circuit(s).
c) Yes, curare would cause a decrease in the activity of one or more components in the
polysynaptic stretch reflex circuit(s).
d) Yes, curare would cause a decrease in the activity of one or more components in both
stretch reflex circuit(s).
e) Yes, curare would cause an increase in the activity of one or more components in the
monosynaptic stretch reflex circuit(s).
f) Yes, curare would cause an increase in the activity of one or more components in the
polysynaptic stretch reflex circuit(s).
g) Yes, curare would cause an increase in the activity of one or more components in both
stretch reflex circuit(s).
