Answer:
English:question-Because the body responds to stimuli...
answer:The human body reacts to external stimuli, both physical and chemical, mechanical or electromagnetic, that trigger functional reactions in the body. ... To receive these stimuli, the body uses the senses: the ears, the nose, the mouth, the eyes, and the skin. Neurons are connected throughout the human body. When a stimulus is detected, the nerve signal is passed along neurons until it reaches the central nervous system. ... The human brain processes stimuli continuously. As the information is processed, the brain may send signals back to the body that causes a response. In physiology, a stimulus (plural stimuli or stimuli) is a detectable change in the physical or chemical structure of an organism's internal or external environment. The ability of an organism or organ to respond to external stimuli is called sensitivity. A stimulus is an environmental cue from either the internal environment or the external environment The stimuli are detected by receptors, which pass a signal along to the brain or spinal column through sensory neurons. The brain and spinal column make up the CNS, and they coordinate the body's response to the stimuli.
Spanish:Porque el cuerpo responde a los estímulos
answer:El cuerpo humano reacciona a estímulos externos, tanto físicos como químicos, mecánicos o electromagnéticos, que desencadenan reacciones funcionales en el cuerpo. ... Para recibir estos estímulos, el cuerpo utiliza los sentidos: los oídos, la nariz, la boca, los ojos y la piel. Las neuronas están conectadas en todo el cuerpo humano. Cuando se detecta un estímulo, la señal nerviosa pasa a lo largo de las neuronas hasta que alcanza el sistema nervioso central. ... El cerebro humano procesa los estímulos continuamente. A medida que se procesa la información, el cerebro puede enviar señales al cuerpo que provocan una respuesta. En fisiología, un estímulo (estímulo plural o estímulos) es un cambio detectable en la estructura física o química del ambiente interno o externo de un organismo. La capacidad de un organismo u órgano para responder a estímulos externos se llama sensibilidad. Un estímulo es una señal ambiental del ambiente interno o externo. Los estímulos son detectados por los receptores, que transmiten una señal al cerebro o la columna vertebral a través de las neuronas sensoriales. El cerebro y la columna vertebral forman el SNC, y coordinan la respuesta del cuerpo a los estímulos.
