Answer:

The correct answer is the secretions of the urothelium.  

Explanation:

The epithelium coating the urinary bladder surface is known as the urothelium. It is a specific kind of cell exhibiting high elasticity and numerous cellular activities. It signifies the initial line of bladder resistance and a boundary in between the defense mechanisms and pathogens. The purposes of the urothelium comprise immune responses, control of permeability, and communication between the cells that appears to perform the main role in reacting towards infections and injuries.

I think that he correct answer is the secretions from the urothelium. The tight junctions between the urothelial cells, specialized "umbrella cells" lining the surface, and direct bactericidal activity of the vesical mucosa are thought to be capable of defending the bladder from bacteria in the urine.

Agents that paralyze skeletal muscle by simple competitive inhibition of acetylcholine at muscle receptor sites are called?
Fed [463]

Agents that paralyze skeletal muscle by simple competitive inhibition of acetylcholine at muscle receptor sites are called?

a. nondepolarizing

b. depolarizing

c. antagonizing

d. repolarizing

Answer:

a. nondepolarizing

Explanation:

As the nerve impulse arrives, the synaptic end bulbs of the motor neurons release acetylcholine in the synapse. Acetylcholine binds to its receptors present at the motor endplate. This results in the opening of an ion channel in the ACh receptor to allow the movement of the Na+ into the cell. This makes the inside of the muscle fiber more positively charged, that is, depolarized.

Depolarization triggers a muscle action potential. Drugs or chemicals that paralyze skeletal muscle by competitive inhibition of acetylcholine at muscle receptor sites are called non-depolarizing as they do not allow the acetylcholine to facilitate the depolarization of the muscle fiber.

Answer:

this note might help you :

Explanation:

If the enzyme changes shape, the active site may no longer bind to the appropriate substrate and the rate of reaction will decrease. Dramatic changes to the temperature and pH will eventually cause enzymes to denature.
