a. Growth hormone:regulates growth

(bones, muscles, tissues)

Verne Troyer, 30, describes himself as a "little person or dwarf," is 2 feet, 8 inches tall.

14-year old Khagendra Thapa Magar shown in the picture with another boy is only 50 centimetres (20 inches) tall and has been submitted to the Guinness world record as the world's smallest person. The previous world record holder was a Jordanian boy at 25.5 inches tall. Weighing only 4.5 kilograms, he is shown in exhibitions to collect fund for his education.

Gul Mohammed (February 15, 1957 – October 1, 1997) of New Delhi, India, according to The Guinness Book of World Records, was the shortest adult human being whose existence and height have been independently verified.On July 19, 1990, he was examined by Ram Manohar Lohia Hospital, New Delhi, India and he stood 1 foot 10.5 inches (57 cm) tall and weighed 37.5 lbs (17.0 kg). He died on October 1, 1997, from respiratory complications and after a long struggle with asthma and bronchitis, acquired due to heavy smoking.

Jyoti Amge (born December 16, 1993), a resident of Nagpur, India, is currently the world's smallest girl according to the Limca Book of Records. She has a growth anomaly, that has restricted her height to 23 inches (58 cm), and her weight to 11 pounds (5.25 kg).

Robert Pershing Wadlow (February 22, 1918 – July 15, 1940) was a man who, to this day, is the tallest person in medical history for whom there is irrefutable evidence. He is often known as the "Alton Giant" because of his Alton, Illinois hometown. Robert Wadlow reached 8 feet 11.1 inches (272 cm) in height and weighed 490 pounds (220 kg) at his death. His great size and his continued growth in adulthood was due to an abnormally high level of human growth hormone. He showed no indication of an end to his growth even at the time of his death.

Robert Wadlow's size began to take its toll: he required leg braces to walk, and had little feeling in his legs and feet. Despite these encounters, Robert Wadlow was never confined to a wheelchair.

On July 4, 1940, while making a professional appearance at the National Forest Festival, a faulty brace irritated his ankle, causing a blister and subsequent infection. Doctors treated him with a blood transfusion and emergency surgery, but his condition worsened and on July 15, 1940, he died in his sleep. He was 22.

Sandy Allen—the world's tallest woman, according to Guinness World Records—died on Wednesday, August 13 in the Indiana nursing home where she lived. Allen was 53 years old and stood seven feet, seven inches (2.3 meters) tall—a full inch taller than Chinese basketball star Yao Ming.

As a child, Allen developed a tumor in her pituitary gland. As a result of the tumor, she developed gigantism—her bones grew excessively, causing, among other things, her extraordinary height.

Although the cause of Allen's death is unknown, she suffered from diabetes, frequent infections, breathing difficulties and kidney failure. She spent much of her later years confined to a wheelchair.

Acromegaly is a hormonal disorder that develops when your pituitary gland produces too much growth hormone during adulthood. When this happens, your bones increase in size, including those of your hands, feet and face. Acromegaly usually affects middle-aged adults.

It is characterized by an enlarged face and hands. As the face changes shape, the jaw may protrude, the nose may enlarge, and the lips may thicken

The most common symptoms experienced by people with Acromegaly are (in this order):1

-Enlarged hands (88%)-Enlarged feet (87%)-Enlarged lips, nose or tongue (78%)-Joint pain (72%)-Prominent cheekbones, jaw, forehead (71%)-Sleep apnea/snoring (69%)-Perspiring (65%)

b. Thyroid stimulating hormone (TSH):

stimulates thyroid

Follicle stimulating hormone (FSH) and Leutinizing hormone (LH): stimulate testes and ovaries
