Question
Chapter 11, Problem 10RQ
Summary Introduction
To determine: The kind of receptor found in the postsynaptic cell in the neuromuscular junction.
Introduction: A receptor is a communication link between the external stimuli and the internal environment of the body. There are several receptors present in the body of an organism to manipulate the standard internal conditions of the body.

- Curare is a dangerous poison extract from plants that can block the binding site of Acetylcholine receptor channels in neuromuscular junctions. Which of the following molecular events will curare directly inhibit or prevent from occurring? Action potential traveling down the sarcoplasmic reticulum End-plate potential forming Release of calcium ions from the sarcoplasmic reticulum Release of Acetylcholine from axon terminalsarrow_forwardPlease fill in the blanks: A(n) ["action potential", "muscle twitch", "contraction"] consists of a wave of depolarization that moves along the plasma membrane of a neuron or a muscle fiber. This wave of depolarization is immediately followed by repolarization. Depolarization is when the cell's membrane potential becomes more ["resting", "negative", "positive"] . Depolarization occurs when calcium channels open in the plasma membrane. Repolarization is when the cell's membrane potential becomes more ["resting", "positive", "negative"] , returning the cell to its resting potential. Repolarization occurs when ["calcium", "sodium", "potassium"] channels close and ["sodium", "calcium", "potassium"] channels open.arrow_forwardWhat is the difference between equilibrium potential, membrane potential, and action potential (neurons)?arrow_forward
- The neuromuscular junction is similar to synapses in the central nervous system in that: (SELECT ALL THAT APPLY) a.) A wave of depolarization in the presynaptic terminal opens voltage gated Ca++ channels b.) Calcium entry through voltage-gated channels in the presynaptic terminal is necessary for the release of neurotransmitter c.) The neurotransmitter released from the pre-synaptic terminal binds to specific receptors on the post-synaptic side d.) The release at the neuromuscular junction of acetylcholine results in just a fraction of a mV depolarization on the post-synaptic membrane which is similar to what is seen at synapses in the central nervous system.arrow_forwardDescribe the role of a presynaptic terminal, synaptic vesicles,synaptic cleft, and acetylcholine in neuromuscular function?arrow_forwardAn antibody has been isolated that binds to F-actin but not to G-actin. Whatstructural feature(s) of F-actin do you suppose the antibody binds (i.e., howis the antibody able to distinguish between these two forms of actin)?arrow_forward
- Put the following events in chronological order. (Some of the steps may be missing.)1) Ca*+ floods into the pre-synaptic neuron.2) ch (Acetylcholine) binds to ACh receptors in the sarcolemma.3) Na+ floods into the post-synaptic muscle cell.4) The A.P arrives at the pre-synaptic terminal causing Ca+ channels to open.5) Ach from the synaptic vesicles spills into the pre-synaptic cleft.6) A post-synaptic action potential results in the muscle fiber (depolarizationarrow_forwardHow do both negative and positive feedback contributeto the changes in membrane potential during an actionpotential?arrow_forwardThe following is a graph of membrane potential over time during an action potential.

- What is the typical resting membrane potential of a neuron?arrow_forwardFollowing the arrival of an action potential in stimulated cells, synaptic vesicles rapidly fuse with the presynaptic membrane. This happens in less than l ms. What mechanisms allow this process to take place at such great speed?arrow_forwardMatch each type of membrane potential (resting, threshold, graded, or action) to its definition: a) The membrane potential at which voltage gated sodium channels open. b) The membrane potential that triggers the action potential. c) Change in membrane potential that may or may not reach threshold and that may be depolarizing or hyperpolarizing. d) Rapid, strong depolarization followed by immediate repolarization. This potential is self-renewing if the right ion channels are nearby.arrow_forward
