4. Draw a synapse between 2 neurons. Label the following: Presynaptic neuron, Postsynaptic neuron, Synaptic vesicles, Voltage-regulated calcium channel, Chemical-regulated sodium channel. 5. Draw a diagram of the preganglionic neuron, postganglionic neuron, and effector for both Sympathetic Nervous System and Parasympathetic Nervous System. indicate which neurotransmitter is released by each neuron and label the receptors at all locations for the neurotransmitter. 6. Which cells have a resting membrane potential? Which cells can have an action potential? 7. Circle which of...
1)What happens to the post-synaptic membrane potential if you block pre-synaptic Na channels? 2) What happens to the post-synaptic membrane potential if you block pre-synaptic K channels? 3) What happens to the post-synaptic membrane potential if you block pre-synaptic Ca channels?
Question 5 3 pts Regulated secretion of neurotransmitters is accomplished in part by membrane fusion allows Upon A) sorting in the TGN, clathrin coat formation, exocytic vesicles to merge with the plasma membrane O B) inhibition of SNARE interactions, opening of voltage-gated Ca2+ channels, release of vesicle contents C) COPI-coated vesicles, merging with vesicular tubular clusters, O-linked glycosylation of cargo D) the recycling endosome, invagination of endosome membrane, formation of a multivesicular body 3 pts Question 6

3. Saxitoxin prevents sodium channels from opening. Membrane Potential - - - - - - - - Time 4. Neostigmine competitively inhibits acetyelcholinesterase (the enzyme that breaks down the neurotransmitter acetylcholine). This means the neostigmine gives the neurotransmitter more time to interact with receptors on the post-synaptic cell before the neurotransmitter is broken down by enzymes. Membrane Potential Time
2. Curare blocks acetylcholine receptors at the motor end plate. This would result in: (1) Inability of the muscle fiber to respond to nervous stimulation (2) Increased muscle stimulation (3) Increased actylcholinesterase production (4) Lack of calcium uptake by the muscle fiber 3. The structure that is analogous to the Zline of skeletal muscle is the __ of smooth muscle. The structure that is analogous to troponin of skeletal muscle is _ muscle is ___ of smooth muscle. 4.
