the external urethral sphincter is under ___________ control.

Answers

Answer:

It is controlled by the deep perineal branch of the pudendal nerve.

Explanation:

.

The external urethral sphincter is basically under the voluntary control.

What is voluntary control?

Only one of the body's 3 chief muscle systems is subject to voluntary control, which means we may consciously decide the amount in which much influence it has.

The external urethral sphincter can be controlled voluntarily. The urethra is surrounded by skeletal muscle, which can be intentionally contracted to stop the passage of urine from the bladder.

One can delay urination when necessary and regulate the timing and flow of urine thanks to this voluntary control of the external urethral sphincter.

The internal urethral sphincter, a smooth muscle at the base of the bladder, is under involuntary control as well as contracts instinctively to stop urine from flowing back into the bladder during urination.

Thus, the answer is voluntary control.

Which of the following is medicine misuse?
taking medication not prescribed for you

taking medication which was prescribed for you in the past

mixing medications with drugs

all of the above

Answers

Answer:

D.) "All of the above".

Explanation:

Misuse of prescription drugs means taking a medication in a manner or dose other than prescribed; taking someone else's prescription, even if for a legitimate medical complaint such as pain; or taking a medication to feel euphoria.

All of the above, because if you take medicine prescribed for you in the past you might take too much or too little, or not even need it at all. If you take medicine which isn’t prescribed for you, then that would be stealing, but it might harm your health depending on the type/strength, and mixing medicine with drugs…I don’t think I need to explain that one

True false

Answers

False Chemical cold packs should be stored in a refrigerator.

A chemical cold pack consists of a bag within a bag. The inner bag contains water. The outer bag typically contains urea or ammonium nitrate. When the inner bag is broken, the water mixes with the chemical in the outer bag, dissolving it. As the chemical dissolves, this is an endothermic reaction. As the reaction absorbs energy, the device cools down.

This cooling will occur independent of whether the cold pack is stored in the refrigerator or not.

Describe the relationship between poor nutrition, lack of physical activity and chronic disease

Answers

Answer:Before looking at the relationship between nutrition and HIV, it is important to understand the relationship between nutrition and infection in general. Poor nutrition increases the body’s vulnerability to infections, and infections aggravate poor nutrition. Inadequate dietary intake leads to poor nutrition and lowers immune system functioning. Poor nutrition reduces the body’s ability to fight infections and therefore helps increase the incidence, severity, and length of infections. Symptoms that accompany infections such as loss of appetite, diarrhea, and fever lead to reduced food intake, poor nutrient absorption, nutrient loss, and altered metabolism. All of these contribute to weight loss and growth faltering, which further weaken the immune system.

Not getting enough physical activity can lead to heart disease—even for people who have no other risk factors. 2 Type 2 Diabetes. Not getting enough physical activity can raise a person’s risk of developing type 2 diabetes

chronic diseases are well estab-lished and well known; a small set of common risk factors are responsible for most of the main chronic diseases. These risk factors are modifiable and the same in men and women: unhealthy diet; physical inactivity; tobacco use.
