Endocrine System
The endocrine system is made up of glands which control and coordinate body functions and maintain homeostasis inside the body.
2,103 Questions
What is the term for chemical substances produced by glands of the endocrine system?
Hormones are chemical substances secreted by endocrine glands
Which hormones do the ovaries secrete?
The ovaries secrete progesterone and Oestrogen, the testes secrete testosterone and oestrogen. These are known as androgenic hormones.
Who is father of endocrinology?
It was China that began the earliest study of endocrinology. It was Thomas Addison an English physician who is father of endocrinology. His work laid the foundation for modern endocrinology.
What gland is an exocrine gland?
A gland that secretes a substance out through a duct.These salivary glands, sweat glands are exocrine gland.
What does a level of tsh 0.06 mean?
The normal TSH value is between 0.5 to 5.0. A reading of 6.11 suggests you are close to hypothyroidism, or having an underactive thyroid, and don't have enough thyroid hormone circulating in your body. Your doctor will likely place you on a thyroid medication.
Do castration and vasectomy have the same effects on the endocrine and reproductive functions?
Castration, removal or destruction of the testes, has a drastic effect of endocrine functions, as the testes are major sites of hormone production. As a vasectomy leaves the testes in tact, there is no effect on the endocrine system. Both methods prevent reproduction.
Which organ of the female reproductive system is functionally part of the endocrine system?
The ovaries are part of the woman's reproductive system that produce the estrogen hormone, which is produced in three varieties, and the progesterone hormone.
What is the eighth gland in the endocrine system?
The glands present from head to foot in the human body are as:
Pineal (head)
Hypothalamus
Pitutary
Thyroid
Parathyroid
Thymus
Adrenal
Kideny
Pancreas
Intestine
Ovary (in female)
Testis (in male).
What organ system does the pituitary glad belong to?
The pituitary gland is part of the endocrine system. The endocrine system and the nervous system function together to maintain homeostasis. The two work together as one system.Glands of the endocrine system are widely scattered throughout the body.The pituitary gland is known as the master gland and it is divided into an anterior and posterior part.
The pituitary secretes somatotrophs, corticotrophs, thyrotrophs, lactrotrophs and gonadotrophs.
How risky is a thyroid operation?
There are many dangers or risks that could be taken from getting thyroid surgery. They are:
1) biopsy or lumpectomy - removing a small part of the thyroid
gland; 2) lobectomy - removing half of the thyroid gland; 3) removing
nearly all of the thyroid gland (subtotal thyroidectomy - leaving a small
amount of thyroid tissue bilaterally or near-total thyroidectomy - leaving
about one gm or cm of thyroid tissue on one side); or 4) total
thyroidectomy, which removes all identifiable thyroid tissue. There are
specific indications for each of these operations. The main risks of a
thyroid operation involve possible damage to important anatomical
structures near the thyroid, primarily the parathyroid glands (which
regulate calcium levels) and the recurrent and external laryngeal
nerves (which control the vocal cords)

What is propylthiouracil used for?
Propylthiouracil is used to treat hyperthyroidism. It works by stopping the thyroid gland from making thyroid hormone.
Propylthiouracil should usually be given only to people who are allergic to or cannot tolerate methimazole (Tapazole) or who are in the first trimester of a pregnancy.
What organs are considered to be the central endocrine organs?
hypothalamus, pituitary gland, thyroid, parathyroid, adrenal glands, pancreas, ovaries, testes
Which body system includes the pituitary thyroid and adrenal glands?
Part of the endocrine system, these endocrine glands help to regulate homeostasis.
What medication is administered to slow the ability of the thyroid gland to produce thyroid hormone?
Antithyroid medications are used to slow down the thyroid gland's ability to produce thyroid hormones. The most common antithyroid medications are propylthiouracil (PTU) and methimazole (Tapazole). These medications are most commonly prescribed to patients diagnosed with hyperthyriodism or Graves' disease.
What endocrine organ produces vasopressin?
Vasopressin is produced in the postieror pituitary gland. This glad also produces oxytocin.
What is the classification of the muscular system?
The muscular system is an organ system consisting of skeletal, smooth and cardiac muscles. It permits movement of the body, maintains posture, and circulates blood throughout the body. The muscular system in vertebrates is controlled through the nervous system, although some muscles (such as the cardiac muscle) can be completely autonomous.
There are three distinct types of muscles: skeletal muscles, cardiac or heart muscles, and smooth (non-striated) muscles. Muscles provide strength, balance, posture, movement and heat for the body to keep warm.
CARDIAC MUSCLE:
Heart muscles are distinct from skeletal muscles because the muscle fibers are laterally connected to each other. Furthermore, just as with smooth muscles, they are not controlling themselves. Heart muscles are controlled by the sinus node influenced by the autonomic nervous system.
SMOOTH MUSCLE:
Smooth muscles are controlled directly by the autonomic nervous system and are involuntary, meaning that they are incapable of being moved by conscious thought. Functions such as heart beat and lungs (which are capable of being willingly controlled, be it to a limited extent) are involuntary muscles but are not smooth muscles.
What does the substances that secretes by the endocrine glands?
The endocrine system produces chemical messengers called hormones. Examples of hormones include thyroxine, adrenaline, and estrogen.
Why are fats important for endocrine system?
Fats help you warm up and not get injured easily. It holds up your cushion and not let your body get slopped down like a slug. When it is winter, your fats help you stay warm and cozy. If you didn't have any fat, which is probably impossible, well, you would freeze easily and when you want to run or even walk, you will fall down, break your bone, or get injured badly if it wasn't for fat.
What are the endocrine and exocrine products that come from the testes?
Endocrine - Testosterone
Exocrine - Sperm
What advantage does the nervous system have over the endocrine system?
The messages of the nervous system are relayed by nervous impulses, which are very fast and short-acting. In contrast, the messages of the endocrine system are sent via chemical messengers (hormones) distributed by the circulatory system. This distribution in your blood is much slower than the electrical impulses of the nervous system.
What hormones are regulated by positive feedback under certain circumstances?
Oxytocin in the process of giving birth. Oxytocin causes uterine contraction, which causes the baby to push up against the cervix, which causes more oxytocin to be released. And the cycle continues until the baby is born.
Can an under-active thyroid gland become over-active?
Overactive thyroid (hyperthyroidism).
About hyperthyroidism
Your thyroid is an endocrine gland. This means that it secretes hormones into your bloodstream. Hormones are chemicals produced by your body to help regulate how your cells and organs work. They are sometimes called chemical messengers.

Your thyroid gland makes two hormones: thyroxine (also called T4) and triiodothyronine (also called T3). Together, these hormones regulate your body's growth and metabolism. Your metabolism is how quickly your body burns energy and how quickly reactions in your body happen. Your rate of metabolism affects lots of things, such as how much you weigh and how much you sleep.
The production of your thyroid hormones is controlled by another hormone called thyroid stimulating hormone (TSH). This is made by an endocrine gland in your brain called the pituitary gland.
What is hyperthyroidism?
Hyperthyroidism is when your thyroid gland is overactive and produces excess thyroid hormones. This speeds up your body's metabolism, meaning that organs and processes in your body work faster.
Symptoms of hyperthyroidism
Hyperthyroidism has many different symptoms. In general, the symptoms relate to a speeding up of your body's metabolism. Symptoms include:
feeling nervous, irritable or emotional
tremor (shaking)
sleeping poorly
being intolerant of heat and sweating more than usual
losing weight despite having an increased appetite (although around one in 10 people will gain weight)
feeling tired
muscle weakness
increased heart rate or palpitations
having infrequent periods or problems getting pregnant
having more frequent bowel movements or diarrhoea
shortness of breath, especially when exercising
loss of hair or finer hair than usual
swelling of your thyroid gland (goitre)
swollen/red eyes, or double vision
If you have some, or all, of these symptoms, see your family doctor.
