Answers

Answer: Many left-handed people report being able to use their right hand very well for a certain burden(task), because of needing to adapt to tools which are usually designed for right-handed people like scissors, golf clubs, and some people are also mix-handed, where they perform some tasks with one hand and other tasks with the opposite hand. Some people have true ambidexterity where they can perform burden(task) equally well with both hands. Learning Point is were children begin to develop hand dominance around about 2 to 3 years and this should be well developed by the age of 5 and fully developed by the age of 6. Use of a dominant hand before 2-3 years time may occur because of abnormal fine motor development. It could also be the result of an intracranial injury or an injury to a limb with appropriate compensation by the other limb. The development of hand dominance after the age of 6 years, again may indicate abnormal development.

what do you do when you got stabbed in the back by a pencil? And it hurts?

Answers

Answer:

prolly just. give it some time unless it's bleeding :/

Explanation:

also square up with whoever had the auDaCitY to stab u with a pencil

Answer:

Explanation:If you're stabbed and the pencil is literally stuck in your body, leave the pencil where it is, call 911 and don't do anything but remain seated or reclined in a position of comfort (if it's possible to sit or lay down safely) Let EMS handle it.

If you got poked hard with the pencil and the wound is just a small dot of broken skin, or shallow skin puncture, wash and clean the wound of graphite, wood splinters, paint chips or whatever else may have been embedded in the skin. If you can't be sure all the debris out, or the pencil was covered in unidentified filth to begin with, go to the emergency room.

Otherwise, bandage it and apply pressure if it's clean but still bleeding. Make an appointment to see your primary. but heres how you clean it,

Wash your hands. This helps avoid infection.

Stop the bleeding. Apply gentle pressure with a clean bandage or cloth.

Clean the wound. Rinse the wound with clear water for five to 10 minutes. If dirt or debris remains in the wound after washing, use tweezers cleaned with alcohol to remove the particles. See a doctor if you can't remove all of the debris. Clean the skin around the wound with soap and a washcloth.

Apply an antibiotic. Apply a thin layer of an antibiotic cream or ointment (Neosporin, Polysporin). Certain ingredients in some ointments can cause a mild rash in some people. If a rash appears, stop using the ointment and seek medical care.

Cover the wound. Bandages help keep the wound clean.

plz help this question is 100 points :) Identify three hormones the pituitary gland produces by listing them below. Briefly describe the function of each.

Answers

Answer:

1. Human growth hormone (HGH)

2.Thyroid-stimulating hormone (TSH)

3. Luteinizing hormone (LH)

Explanation:

1. HGH, produced by the pituitary gland, spurs growth in children and adolescents. It also helps to regulate body composition, body fluids, muscle and bone growth, sugar and fat metabolism, and possibly heart function.

2. Thyroid-stimulating hormone (also known as thyrotropin, thyrotropic hormone, or abbreviated TSH) is a pituitary hormone that stimulates the thyroid gland to produce thyroxine (T4), and then triiodothyronine (T3) which stimulates the metabolism of almost every tissue in the body.

3. LH is made by your pituitary gland, a small gland located underneath the brain. LH plays an important role in sexual development and functioning. In women, LH helps control the menstrual cycle. It also triggers the release of an egg from the ovary.

Hey there, I will be more than happy to write you a paragraph.

     What is anorexia? Anorexia nervosa is an eating disorder causing people to obsess about weight and what they eat. Anorexia is characterized by a distorted body image, with an unwarranted fear of being overweight. Symptoms of anorexia are extreme weight loss or not making expected developmental weight gains . thin appearance . abnormal blood counts . fatigue , and insomnia.  Things that anorexia can cause is anemia., heart problems, such as mitral valve prolapse, abnormal heart rhythms or heart failure , bone loss (osteoporosis), increasing the risk of fractures , loss of muscle , absence of a period , decreased testosterone , gastrointestinal problems, such as constipation, bloating or nausea , electrolyte abnormalities, such as low blood potassium, sodium and chloride , kidney problems. If a person with anorexia becomes severely malnourished, every organ in the body can be damaged, including the brain, heart and kidneys. This damage may not be fully reversible, even when the anorexia is under control. Anorexia is extremely dangerous and can be fatal. There's no guaranteed way to prevent anorexia nervosa. Primary care physicians (pediatricians, family physicians and internists) may be in a good position to identify early indicators of anorexia and prevent the development of full-blown illness. For instance, they can ask questions about eating habits and satisfaction with appearance during routine medical appointments.
