for making proteins.
What do ribosomes do? - 🧠ANSWER ✔✔Make proteins (protein synthesis)
Neurotransmitters - 🧠ANSWER ✔✔chemical messengers that cross the
synaptic gaps between neurons
Neurotransmitters at the parasympathetic postganglionic synapses -
🧠ANSWER ✔✔Acetylcholine and nitric oxide
Atropine Neurotransmitters - 🧠ANSWER ✔✔Atropine is a muscarinic
receptor antagonist that is used to inhibit the effects of excessive vagal
activation on the heart, which is manifested as sinus bradycardia and AV
nodal block. Therefore, atropine can temporarily revert sinus bradycardia to
normal sinus rhythm and reverse AV nodal blocks by removing vagal
influences.
