Binding of acetylcholine to nicotinic receptors causes depolarization by opening channels that primarily permit sodium to permeate the membrane.

Acetylcholine is a neurotransmitter that plays a vital role in signal transmission within the nervous system. Nicotinic receptors are a type of ligand-gated ion channels found in the neuromuscular junction and central nervous system. When acetylcholine binds to these receptors, it leads to a conformational change, causing the channel to open, this opening allows positively charged ions, such as sodium, to flow across the membrane. The influx of sodium ions creates a depolarization event, which is a shift in the membrane potential towards a more positive value, this change in the membrane potential brings the neuron closer to the threshold needed to generate an action potential, which is an electrical signal that propagates along the neuron's axon.

The action potential is crucial for transmitting information from one neuron to another, ultimately allowing for communication between different parts of the nervous system. In summary, the binding of acetylcholine to nicotinic receptors is a critical step in neuronal signal transmission, as it causes depolarization by opening ion channels that allow sodium ions to permeate the membrane. This process ultimately leads to the generation of action potentials and communication between neurons.

Answer:

El enfisema pulmonar disminuye la cantidad de tejido pulmonar, disminuyendo de este modo la cantidad de oxígeno que llega a la sangre (hipoxemia). El enfisema está asociado a diferentes trastornos incluyendo infecciones respiratorias recurrentes, pérdida de peso, debilidad muscular e hinchazón de los miembros inferiores.

Explanation:

El enfisema pulmonar es una enfermedad causada por la destrucción de los alvéolos pulmonares la cual está asociada a un aumento en la dificultad para respirar. Las principales causas de esta enfermedad son la exposición continua al humo del cigarrillo y otras sustancias nocivas para la salud, como así también a contaminantes presentes en la atmósfera. El enfisema pulmonar va progresivamente destruyendo las paredes alveolares pulmonares y los vasos sanguíneos que las recorren, disminuyendo así la elasticidad pulmonar, aumentando la proporción de aire que recorre los pulmones y de este modo también aumentando la distensibilidad pulmonar. Esta enfermedad disminuye la capacidad de oxigenar la sangre, generando una sensación constante de falta de aire (disnea) y cuadros progresivamente más severos de hipoxemia. Cuando el enfisema pulmonar se encuentra en grado avanzado, la única opción viable es el reemplazo del órgano dañado mediante un trasplante pulmonar. El enfisema puede estar asociado a infecciones respiratorias recurrentes (resfriados, gripe), pérdida de peso, debilidad muscular e hinchazón de los miembros inferiores (tobillos, pies y piernas).

The impulses carried to the heart by means of fibers that secrete acetylcholine are called parasympathetic impulses.

Parasympathetic impulses are part of the autonomic nervous system, which controls involuntary bodily functions. These impulses are carried to the heart via fibers called vagus nerves, which secrete the neurotransmitter acetylcholine.

When acetylcholine binds to specific receptors in the heart, it causes a decrease in heart rate and the force of contraction, leading to a more relaxed state for the heart. This is in contrast to the sympathetic impulses, which increase heart rate and contractility.

Parasympathetic impulses play a crucial role in maintaining the balance between relaxation and excitation in the heart, contributing to overall cardiovascular health.
