when a surgeon is operating on a bone, great care is taken to preserve the periosteum. why is it important to bone healing to take care of this delicate structure

Answers

Answer with Explanation:

It is important to take good care of "periosteum" when operating a bone because this membrane is very thin and it consists of the "osteoblast cells," which can be found in the inner layer. These cells aid in the recovery and repair of fractures in bone. This is the reason why even after falling from the tree and sustaining a fracture, a child has the ability to recover his bone injury in time. However, it takes a little longer for the bone to regenerate when it comes to older people. On the other hand, its outer layer is responsible for the blood supply in the bones.

• How do diet and exercise affect muscle size?​

Answers

Answer:

Resistance exercise affects muscles by increasing the formation of myofibrils, thereby increasing the thickness of muscle fibers

Explanation:

This added structure causes hypertrophy, or the enlargement of muscles, exemplified by the large skeletal muscles seen in body builders and other athletes.

To make gains you have to have the right nutrients in your body to construct muscle. This means that what you eat, and how much, is essential in making muscle gains. Lifting and doing strength training without adequate nutrition, especially without enough protein, can actually lead to loss of muscle tissue.

Muscle tone referring to the activity of the muscle, not toned muscles in the traditional sense decreases and the interstitial fluid and blood pumped into the muscles during the workout disperses, causing your muscles to appear smaller. But again, it takes a long time for you to actually lose muscle size.

Explanation:

The minimum amount of stimuli that can be detected by one of your senses, such as faintest of smells humans can detect is called the
a) extrasensory perception
b) sensory receptor
c) adaptation syndrome
d) absolute threshold

Answers

Answer:

The minimum amount of stimuli that can be perceived by the senses is called the absolute threshold (option d).

Explanation:

Absolute threshold implies the capacity of a sensory receptor to perceive very small stimuli and marks the beginning of the perception of a specific sense. This means that any stimulus whose intensity is less than the absolute threshold will not be perceived.

The capacity to perceive stimuli is individual, and for each person the absolute threshold is different, which is why there are people with a better sense of smell or a greater capacity to differentiate flavors. Repeated stimuli can cause the absolute threshold to increase, decreasing the capacity to perceive very small stimuli.

the other options are not correct because:

    a. Extrasensory perception is an unproven phenomenon that involves perceiving stimuli by senses other than the five already known.

    b. A sensory receptor is a structure capable of detecting stimuli and converting them into nerve impulses.

    c. The adaptation syndrome is more linked to stress and the presence of stressors.

Which statement about detoxification is true? Most people are able to make lasting changes after detoxification. It is only the first step in treatment. It is rarely needed for successful treatment. It usually occurs outside of a formal treatment setting.

Answers

Answer: It is only the first step in treatment.

Explanation:

When it comes to treating addiction as well as some other medical ailments, detoxification is the first step in treatment. The body needs to shed the drugs in the system and the effects these drugs bring along with them as well.

Detoxification alone will not lead to lasting changes being made so option A is wrong. Detoxification is always needed for a successful treatment so option C is wrong. Option D is wrong as well because detoxification occurs within a formal treatment setting s well.
