Homework Answers
3.Botulinum toxin cannot cause any change to the membrane potential as it does not bind to emd palye potential but it can cause rearrangment of presynaptic intermembrane particles induced by potassium stimulation.
4. Botulinus toxin on the end plate will cause a decrease in the threshold potential thus action potential cannot be attained and paralyses occur.
Add Answer to:
Botulinus toxin causes paralysis by binding to presynaptic sites at the neuromuscular junction and prevents release...

Regarding the neuromuscular junction... a. Depolarization of the presynaptic membrane directly causes voltage-gated calcium channels in the membrane to open. b. Action potentials in the sarcolemma directly cause calcium channels to open. c. Action potentials in the sarcoplasmic reticulum indirectly cause the calcium ATPase pump to function, if ATP is present. d. both a) and b) are correct, and c) is incorrect e. a), b) and c) are all correct 2) Following ATP hydrolysis by myosin, which steps occur during...

Part I—The Hospital At last the day had come. Mr. Th ompson was having his wisdom teeth removed. He was tired of the aches and pains and the sight of his puff y face in the mirror every morning. He felt helpless, lying on the gurney watching the ceiling lights whiz by as he was being wheeled to surgery. Mr. Th ompson had selected this particular oral surgeon because of the sign outside his practice that read: “We cater to...
