What is male primary hormone?

The primary male hormone is testosterone, which plays a key role in the development of male reproductive tissues such as the testes and prostate, as well as promoting characteristics like facial hair growth and muscle mass.

What is non-peptide hormone?

A non-peptide hormone is a type of hormone that is not made up of amino acids arranged in a peptide chain. Instead, non-peptide hormones are typically small organic molecules or derivatives that act as signaling molecules in the body. Examples include steroid hormones like cortisol and sex hormones like estrogen and testosterone.

Which hormone regulates platelet formation?

Thrombopoietin is the hormone that regulates platelet formation. It is produced primarily in the liver and kidneys and acts on bone marrow to stimulate the production of platelets.

What hormone work with calatonin to regulate homestasis?

Calatonin works in conjunction with the hormone melatonin to regulate the body's internal clock and the sleep-wake cycle. Melatonin is responsible for signaling to the body when it's time to sleep, while calatonin helps maintain a balanced state of physiological functions to support overall homeostasis.

What large molecule is broken down by thyroid cells to produce thyroid hormones?

Thyroglobulin is the large molecule broken down by thyroid cells to produce thyroid hormones. Thyroid peroxidase enzymes help in this process by cleaving thyroglobulin to release thyroid hormones like thyroxine (T4) and triiodothyronine (T3).

Do neurosecretory cells transport Oxytocin and Anti diuretic hormone to the anterior pituitary gland for storage?

No, neurosecretory cells transport oxytocin and anti-diuretic hormone to the posterior pituitary gland for storage and release into the bloodstream when needed. The anterior pituitary gland produces and releases its own hormones in response to signals from the hypothalamus.

What hormone if produced inadequately would cause sexual immaturity?

Testosterone and in smaller quantities Progesterone for men.

Progesterone and in smaller quantities Testosterone in women.

These are the two hormones directly linked to the sex drive or wanting for sex.

If a person are in lack of these during childhood and later, this results in:

Lack of "proper" development needed in order to propagate.

Even if wanting to, the lack of development would most likely cause infertility.

If sex organs otherwise are properly formed, one should be able to "mature" these by taking drugs containing these hormones.

A fertility clinic would probably be the best place to start asking for help if this is a problem at hand.

State the function of the hormones oxytocin?

Dunno what it does in males (if anything).  In females, it stimulates lactation, mostly.  If given artificially, it can stimulate contraction of the uterus and parturition (doctors use it to induce labor).  But it isn't really clear if the pituitary secretes oxytocin on its own to stimulate labor, or if there is some other mechanism that induces labor.

What is the function of the hypthalamus and the pituitary gland?

According to Wikipedia, one of the most important functions of the hypothalamus is to link the nervous system to the endocrine system via the pituitary gland. When the thyroid receives thyroid stimulating hormone (TSH) from the pituitary gland it produces triiodothyronine which is commonly referred to as T3, thyroxine which is commonly known as T4, and calcitonin.

Why does the body release hormones?

The body releases hormones to regulate various physiological processes such as metabolism, growth, mood, and reproduction. Hormones act as chemical messengers that signal different organs and tissues to perform specific functions in response to changes in the internal and external environment.

What are the 4 hormones used in horticulture?

The 4 hormones commonly used in horticulture are auxins, cytokinins, gibberellins, and abscisic acid. These hormones play key roles in plant growth and development, including cell division, shoot elongation, fruit development, and stress responses. By manipulating the levels of these hormones, horticulturists can control various aspects of plant growth and physiology.

Lack of this hormone may cause dwarfism?

Lack of growth hormone may cause dwarfism. Growth hormone is essential for stimulating growth in childhood and overall development. Deficiency in growth hormone can lead to stunted growth and a condition known as dwarfism.

Can hormones make you darker?

Yes, hormones can influence skin pigmentation. For example, during pregnancy, increased levels of estrogen can sometimes cause hyperpigmentation, leading to areas of darker skin known as melasma. However, hormones alone may not always be the sole cause of skin darkening, as it can also be influenced by other factors like sun exposure and genetics.

How is adrenaline related to chemistry?

Adrenaline is a known chemical with a certain formula and structure. Its effects and actions are well known as part of biological chemistry, and can be readily predicted, reversed or duplicated.

What hormone causes most men to grow facial hair?

The hormone responsible for most men to grow facial hair is testosterone. During puberty, increased levels of testosterone stimulate the growth of facial hair, along with other secondary sexual characteristics.

What does the hormone Atrial natriuretic peptide do?

It inhibits release of renin from the kidneys and of aldosterone from the adrenal cortex.

The result is increased excretion of sodium ions and water from the kidneys and lowered blood volume and blood pressure. Or what you might be looking for is all of the above. :)

Why excess thyroxine causes hyperthyroidism?

Excess thyroxine in the body, known as hyperthyroidism, can occur due to conditions such as Graves' disease or nodules on the thyroid gland. This excess thyroxine leads to an overactive metabolism, resulting in symptoms like weight loss, rapid heart rate, and nervousness. It can also increase the risk of developing health issues such as heart problems and osteoporosis.

Which hormones are secreted by your posterior pituitary gland?

Antidiauretic hormone and Oxytocin are the two hormones released by posterior Pituitary gland. A.D.H. conserve the body water by reducing amount of urine. Oxytocin increases the milk secretion and to induce delivery you put a drip of Oxytocin. It promotes uterine contractions and relaxes the cervix to hasten delivery.

What is the function of the posterior pituitary gland?

The posterior pituitary is made up of axons belonging to cells called neurosecretory cells, whose cell bodies are in the hypothalamus. When these cell bodies are stimulated, the axons in the posterior pituitary releases their hormones into the blood stream. In a way, the posterior pituitary is an extension of the hypothalamus.

What is renal hormones?

The kidneys secrete a variety of hormones, including erythropoietin, and the enzyme renin. Erythropoietin is released in response to hypoxia (low levels of oxygen at tissue level) in the renal circulation. It stimulates erythropoiesis (production of red blood cells) in the bone marrow. Calcitriol, the activated form of vitamin D, promotes intestinal absorption of calcium and the renal reabsorption of phosphate. Part of the renin-angiotensin-aldosterone system, renin is an enzyme involved in the regulation of aldesterone levels.

Is tetany caused by hyposecretion of the thyroid?

No, tetany is not typically caused by hyposecretion of the thyroid. Tetany is usually associated with low levels of calcium in the blood, which can be caused by factors such as hypoparathyroidism or vitamin D deficiency. Hypothyroidism, on the other hand, results from the underproduction of thyroid hormones by the thyroid gland.

Which hormone increases aggressive behavior?

Testosterone is a hormone that is known to increase aggressive behavior in both humans and animals. It is often referred to as the "male hormone" because men typically have higher levels of testosterone than women, which may contribute to differences in aggression levels between genders.
