I'm stuck on this question and I'm in dire need of some help please! I keep getting it partially correct, but it won't show me what I got wrong or right.

Identify ALL of the statements below that accurately describe what goes wrong in the process of muscle contraction when a person gets Botox. *Do NOT select any options that are incorrect!*

  • The receptors for acetylcholine (ACh) on the sarcolemma of muscle cells are permanently activated (by binding of the chemical).
  • The motor neuron at the neuromuscular junction releases TOO MUCH acetylcholine.
  • The level of acetylcholine (ACh) at the neuromuscular junction is too HIGH.
  • The receptors for acetylcholine (ACh) on the sarcolemma of muscle cells are permanently blocked (by binding of the chemical).
  • The motor neuron at the neuromuscular junction CANNOT release any acetylcholine (ACh).
  • The level of acetylcholine (ACh) at the neuromuscular junction is too LOW.
  • The enzyme acetylcholinesterase (AChE) is hyperactivated (meaning it works too quickly).
  • The enzyme acetylcholinesterase (AChE) is inactivated (meaning it doesn't work at al).

Thank you sooo much!
