Explain why increasing extracellular K+ causes the membrane potential to change to a less negative value

Answers

Answer 1

Increasing extracellular K+ increases the positive charge outside the cell, making the inside of the cell (membrane potential) more negative. This inhibits net diffusion of Na+ into or out of the cell.

John fell to the ground and experienced significant pain when putting weight on his right leg. John tried to walk but had to be carried off the field and was taken to the emergency department. At the hospital, it was noted that John had significant swelling at the back of his right leg, had a palpable and visible deformity in the distal calf, and was only able to put small amounts of weight on his right leg.

Christi Brown is meeting with you regarding the bill she received in the mail. When she called to make the appointment, she voiced her confusion about the bill, stating she thought her insurance covered everything. You check her record and see that she met her deductible and now needs to pay 20% of the billed amount of $850. How can you explain how much she owes, as well as the difference between deductible and coinsurance?

Answers

Answer:

The correct answer is - she owes $170.

Explanation:

Health care beneficiaries bills can be divided into two different criteria, they include Co-pay or Co-insurance and deductibles. Co-insurance is an amount that should be born by the patient and the rest will be paid by the insurance companies. On other hand, Deductible is a criterion in which deductible fixed amount a patient must pay each year before their health insurance benefits begin to cover the costs.

So in this question, the 20% of hospital/health care bills is the co-insured amount that should be paid by Christi Brown and the rest will be born by the insurance company.

so she owes:

20*850/100 = 170.

What thermoregulatory mechanism is activated to normalize body temperature in the individual exposed to cold?

a) Decreased blood pressure
b) Vasodiltation of arterioles in the skin
c) Increase in hormones T3 and T4
d) Increased lipogenesis

Answers

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.
