Explanation:
The regulation of body temperature is one of the most critical functions of the nervous system. Here we review our current understanding of thermoregulation in mammals. We outline the molecules and cells that measure body temperature in the periphery, the neural pathways that communicate this information to the brain, and the central circuits that coordinate the homeostatic response. We also discuss some of the key unresolved questions in this field, including: the role of temperature sensing in the brain; the molecular identity of the warm-sensor; the central representation of the labelled line for cold; and the neural substrates of thermoregulatory behavior. We suggest that approaches for molecularly-defined circuit analysis will provide new insight into these questions in the near future.
Answer:a. The concentration of salt in a person's urine increases after that person eats a large bag of salty chips.
Explanation:
Homeostasis is the quality of the body to maintain the normal state of the body with respect to changes occurring in the external environment.
The homeostasis is maintained by involving the negative feedback loops. These loops function in opposite to the stimulus, that triggers them. For example, if the body temperature is high, the negative feedback loop will function to bring the body temperature down towards the set point, or the target value.
The homeostasis can regulate the ion concentration. When the body acquires salt by eating chips, the urge to expel salt through urine also increases. Hence, the ionic concentration of salt is maintained through negative feedback loops altering homeostasis.
