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:
Scientists use triangulation to find the epicenter of an earthquake. When seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. Every earthquake is recorded on numerous seismographs located in different directions.
Explanation:
Answer:
A função do citoplasma é fornecer sustentação esquelética para a célula através da estrutura composta por filamentos e túbulos proteicos. Além disso, todo o conjunto de estruturas mergulhadas no citosol apresenta bastante dinamismo, fato que possibilita à célula realizar alguns movimentos.
No citoplasma, ainda há membranas que atuam como verdadeiras usinas intracelulares, que fornecem energia indispensável à manutenção da vida.
Outro fato que você deveria saber sobre o citoplasma é que ele preenche todo o interior das células eucariontes, sendo delimitado pela membrana plasmática. Já nas células procariontes, o citoplasma fica entre a membrana plasmática e o núcleo da célula.
