- In cholinergic neurotransmission, inhibition of the choline transporter will affect the normal synthesis and release acetylcholineTRUE OR FALSEIn the parasympathetic branch of the autonomic nervous system, there are two cholinergic synapses (synapses mediated by acetylcholine) on the way to the target tissue. The first synapse is in the autonomic ganglion (from the "preganglionic neuron"), and is always mediated by nicotinic acetylcholine receptors (NACHRS). The second synapse (from the "postganglionic neuron") is on the target cell, and is mediated by muscarinic acetylcholine receptors (mAChRs). B. One of these synapses produces a long-lasting hyperpolarization of its target cell. Which synapse, and why?In the parasympathetic branch of the autonomic nervous system, there are two cholinergic synapses (synapses mediated by acetylcholine) on the way to the target tissue. The first synapse is in the autonomic ganglion (from the "preganglionic neuron"), and is always mediated by nicotinic acetylcholine receptors (NACHRS). The second synapse (from the "postganglionic neuron") is on the target cell, and is mediated by muscarinic acetylcholine receptors (mAChRs). C. Which synapse is expected to be blocked by removal of Ca2+ from the external solution?

The second synapse (from the "postganglionic neuron") is on the target cell, and is mediated by muscarinic acetylcholine receptors (mAChRs). A. Which of these synapses is expected to always produce a rapid depolarization of the postsynaptic cell? Explain your answer.Which of the following is characteristic of parasympathetic ganglia the ganglia are formed of the cell bodies of general somatic efferent neurons O the ganglia are formed of the cell bodies of preganglionic neurons parasympathetic autonomic ganglia are ALL found within the walls of the effector glands or organs synapses between preganglionic and postganglionic neurons are formed within the autonomic gangliaMalathion is an insecticide commonly used in the horticultural industry. Many homeowners apply this chemical to their trees to rid them of infestation by aphids or other insects. Malathion is classified as an organophosphate insecticide. Exposure to malathion is very dangerous to humans and animals because it acts as an irreversible inhibitor of acetylcholinesterase. Predict what might happen to synaptic communication between cholinergic neurons if an individual or animal was poisoned with malathion, and clearly describe the mechanisms at work.
