Differentiate among sebaceous, eccrine, and apocrine glands. Sebaceous glands produce a protective substance called sebum that secretes through hairfollicles.
Eccrine opens to the skins surface and produce sweat.
Apocrine glands produce a thick,milky.

Answers

Answer:

The statements are true. Sebum is the main compound produced by the sebaceous gland which is expelled towards the skin through the hairs or the pores of the skin. The eccrine sweat glands are made up of a secretory glomerulus and an excretory duct that open directly to the surface of the skin. The apocrine glands, on the contrary, produce a milky liquid, also colorless and odorless.

Explanation:

The secretion of the sebaceous glands is controlled by the steroid hormones, circulating and produced locally by the pilosebaceous follicle from the precursors of gonadic and surrenalic origin. The sebaceous glands synthesize the sebum that lubricates and protects our skin. The eccrine glands are not connected to the hair follicles and function throughout life, responding to the increase in body temperature due to environmental heat or physical exercise. These glands are more common on the forehead, neck and back, where profuse sweating occurs on hot days and when a person is physically active. The apocrine sweat glands flow into the sebaceous pilo follicle, their content coming out together with the sebum. and they produce highly odorous substances that are responsible for the characteristic odor of areas such as the armpits and sexual organs.

Answers

While cutting the nails of the guinea pig, Paul has accidentally cut the quick of the nail of guinea pig.

Quick is a part of the nails of guinea pig located at the center which appears reddish due to the presence of blood vessels and nerves.

Care must always be taken to avoid cutting the quick part of the nail. Since it is rich in blood supply, any cut to it is highly likely to result in bleeding.

If the nails of guinea pig are translucent, the quick can be easily located. However, if the nails of the guinea pig are black, it becomes difficult to identify the quick region. In such a case, a flashlight can be shone underneath the nail that will help to locate the quick.

You are working with a patient who sustained a spinal cord injury resulting in paralysis of the legs. This person has:
a. hemiplegia.
b.pseudoplegia.
c. paraplegia.
d. diplegia

Answers

Answer:

A patient with a spinal cord injury that resulted in paralysis of the legs has paraplegia (option c).

Explanation:

Paraplegia consists of paralysis of the lower extremities or legs due to injuries to the spinal cord, from the dorsal vertebrae. Other causes of paraplegia include tumors and malformations that affect the spinal cord.

The spinal cord provides the nerves that allow the innervation of the limbs. A spinal cord injury interrupts communication between the brain and the effector (motor) muscles as well as the sensory nerves in the affected limbs, producing paralysis. When it occurs in the legs is called paraplegia.

The other options are not correct because:

    a. Hemiplegia corresponds to paralysis of upper and lower limbs on one side only.

    b. Pseudoplegia is a paralysis that is due to mental disorders such as conversion disorder, without injury to the nervous system.

    d. Dysplegia is associated with motor disorders observed in children with varying degrees of dysfunction or cerebral paralysis.

i weigh 60 kg, what is the best way to reduce my weight to 30 kg?

Answers

gosh if someone else knows please share

Answer:

That is a very concerning weight, unless u are quite short, u shouldn't be weighing 30kg.

Explanation:

You say best way, so I'm gonna go for healthiest way

If you want to lose weight, u have to go on a caloric deficit, as they say, it's 80% diet and 20% exercise. Go on walks if you don't already, walk at a fast pace for about an hour and eat clean. If fast walking is too easy, go on a jog instead. Eat less calories than you are burning per day, but don't starve yourself, you're more likely to gain back all the calories if not more if u starve as it can cause binge eating. Also starving yourself could really cause eating disorders so please don't do that.

I'd like to add it's not easy losing weight at all, so don't feel bad if your progress is very slow, better slow than none.

And like I said, 30kg is not a good or healthy weight to be at unless you are 4ft. Seriously, losing weight is fine but please do not make yourself go to an unhealthy weight.

A child suspected of sexual abuse may show which of the following behavioral findings? Select all that apply.

Panic attacks.
Genital injuries
Sexual acting out
Difficulty sitting or walking
Poor relationship with peers​

Answers

Answer:

Panic attacks

Sexual acting-out

Difficulty sitting or walking

Poor relationship with peers

Explanation:

The question above is asking for "behavioral findings," thus, "genital injuries" is not part of it because it is a physical finding.

Children who are being sexually abused are under a lot of stress, thus, it is common for them to have panic attacks. They have excess fear and worry. They also have a natural tendency to sexually act out against other kids. They will have poor relationship with peers because they don't want to be with other people. Thus, they'd also lose interest in going to school and their performance will be affected. The child also has difficulty sitting or walking and may have bedwetting problems.

One milestone in the development progress of children is the development of a birthmark.
true or false

Answers

Answer:

Its False

Explanation:

False. The development of a birthmark is not a milestone in the progress of children.

What is a birthmark?

Birthmarks typically exist at or shortly after birth, and their progression is unrelated to the common developmental milestones that kids reach as they grow and mature. The majority of kids are expected to develop a certain set of skills or aptitudes by a certain age, such as walking, talking, and socializing.

These developmental milestones are significant indicators of a child's progress and can be used to spot any delays or issues that may need to be addressed. But, a child's development cannot be predicted based on whether or not they have a birthmark.
