Endocrinology | MCQs

Explanation

The thyroid gland produces thyroxine.

It is a hormone essential for regulating metabolism, energy levels, and growth in the body.

It is located at the front of the neck.

Explanation

LH stands for Luteinizing Hormone, which is a protein hormone.

It plays a crucial role in the regulation of the reproductive system,

They including the stimulation of ovulation in females and testosterone production in males.

Explanation

Diabetes cause due to mall functioning of pincrease

The three main types of diabetes are:

Type 1 diabetes

Type 2 diabetes

Gestational diabetes

Type 1 diabetes

Type 1 diabetes is believed to be an autoimmune condition. This means your immune system mistakenly attacks and destroys the beta cells in your pancreas that produce insulin. The damage is permanent.

Type 2 diabetes

Type 2 diabetes starts as insulin resistance. This means your body can’t use insulin efficiently. That stimulates your pancreas to produce more insulin until it can no longer keep up with demand. Insulin production decreases, which leads to high blood sugar.

Gestational diabetes

Gestational diabetes is due to insulin-blocking hormones produced during pregnancy. This type of diabetes only occurs during pregnancy.

Explanation

 The hormone that is not secreted by the anterior pituitary gland is Oxytocin. 

Oxytocin is secreted by the posterior pituitary gland, while the anterior pituitary secretes hormones

Like growth hormone, follicle-stimulating hormone, and adrenocorticotropic hormone

Explanation

This is the typical concentration in a healthy person during fasting.

The normal blood glucose level is about 80–100 mg/dL, which is roughly 0.08% of the blood by weight.

0.8% and 0.7%:

These are closer to the correct range but still slightly higher than what is typically considered normal. 

7.5%:

This is significantly higher than the normal range and would indicate a serious medical condition like diabetes. 

Explanation

Insulin is the hormone secreted by the pancreas, which plays a crucial role in regulating blood sugar levels.

It helps in the metabolism of proteins, starches, and fats by facilitating the absorption of glucose into cells.

Explanation

Explanation

The thyroid gland is part of the endocrine system and produces thyroid hormones,

which deficiency can cause goiter disease.

Cells producing thyroid hormones extract and absorb iodine from the blood and incorporate them into the thyroid hormones.

Explanation

 The endocrine gland that secretes oxytocin is the Pituitary gland. 

While oxytocin is produced in the hypothalamus,

It is stored and released by the posterior pituitary gland. 

Explanation

The hormone that stimulates the mammary glands to enlarge at puberty is estrogen. 

During puberty, rising levels of estrogen in girls trigger the development of breast tissue by promoting the growth of the ductal system and the accumulation of fat tissue.
