Hope this helps you. Do mark me as brainliest.
The only type of human cell that is never replaced is nerve cell.
What is a nerve cell?Neurons are in charge of receiving sensory input from the outside world, sending action potentials to our muscles, and transforming and relaying electrical signals at every step in the process.
The nerve cell is the basic unit of communication in the nervous system (neuron). The cell body, a major branching fiber (axon), and numerous smaller branching fibers comprise each nerve cell (dendrites).
They do not divide in any way. There are only two exceptions to this rule: only two specific areas of the brain can produce new neurons. However, for the most part, the brain is unable to replenish dead neurons.
Thus, nerve cells are the ones that never gets replaced after getting injured.

Edrophonium is a drug the blocks cholinesterase from breaking down acetylcholine in the muscles. Why does this improve Annie's muscle function?
Answers
Answer:
Edrophonium is a drug used for the treatment of myasthenia gravis, a long-term neuromuscular disease that leads to varying degrees of skeletal muscle weakness, which results from antibodies that block or destroy nicotinic receptors at the junction between the nerve and muscle. By blocking cholinesterase, an enzyme which demolish acetylcholine, it increases the amount of acetylcholine in the neuromuscular junction improving the muscle weakness
It improves Annie's muscle function as a result of the acetylcholine not
being able to be broken down in the muscles.
Acetylcholine is a neurotransmitter that sends signals to the brain and other
parts of the body in the activation of the skeletal muscles.
The drug known as Edrophonium which blocks cholinesterase breaking
down acetylcholine in the muscles will thereby lead to more presence of
acetylcholine and a corresponding increase in the muscle functions.
