Endocrine System

Calcitonin is an antagonist to PTH

C cells increase calcitonin secretion due to high blood Ca levels

PTH is secreted due to decrease in Ca level in blood Calcitonin allows osteoclasts to increase bone resorption when blood Ca level decreases.

Progesterone is the hormone that makes cervical mucus viscous, thick, and sticky, making it difficult for sperm to swim through the cervix. This helps prevent fertilization during certain times in a woman's menstrual cycle.

Insulin controls the sugars in your body.
Insulin is a hormone secreted by the beta cells of pancreas which regulates glucose levels (an increase in insulin lowers blood glucose). The pancreas senses the level of glucose in blood and secretes the amount of insulin accordingly.

• Best example of positive feedback is the release of oxytocin during childbirth. Oxytocin is a reproductive hormone in females. Though it is also secreted in males, its function is yet unclear. Secretion of oxytocin occurs in response to nervous stimulation of the hypothalamus. It stimulates and enhances labor contractions. During the movement of the baby towards the birth canal, messages from pressure receptors within the cervix reach the brain to produce oxytocin. Released oxytocin travels to the uterus through the bloodstream and stimulates the uterine wall muscles to contract stronger. These contractions intensify gradually and increase until the baby comes out of the birth canal.
• Labor contractions are stopped when the stimulus to the pressure receptors ends and when oxytocin production stops in turn. Another means of oxytocin release is during lactation where the nipple sends impulses to the hypothalamus upon suckling, leading to contraction of the myoepithelial cells and expulsion of milk under positive feedback control.

Hormones circulate through the endocrine system in the body. They are released by endocrine glands into the bloodstream, which serves as the delivery system to target organs and tissues throughout the body.

GH: growth hormone secreted by the pituitary gland located approximately behind the nose bridge which is prompted by the abnormal growth of a benign tumor which itself can also produce GH. The tumor can start growing anytime after puberty to the point of affecting eyesight by pushing against the optical nerve. The are many but very gradual visible signs of acromegaly. Most obvious are need for larger shoe size, outgrowing rings, bulging bones at the level of eyebrows, protruding jaw, etc Serious unseen effects are those on the cardiac system. According to available statistics, 98% of unchecked acromegaly sufferer do not live beyond 60 years old.

Since it is a relatively rare malady, it goes often unchecked by generalist.

Blood test can detect GH anomalies which can be confirmed by the tumor detected through MIR scanning.

Today's preferred treatment is surgical ablation of the tumor. Followed in some cases or proceeded or treated by a medical treatment: Sandostatin LAR, a monthly injection which may reduce the size of the tumor or hopefully when operating is not prescribed, keep the GH in check.

GnRH (Gonadotropin-releasing hormone) is a hormone produced by the hypothalamus in the brain. It regulates the production and release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the pituitary gland, which in turn control the release of sex hormones from the ovaries and testes. GnRH plays a crucial role in the regulation of reproductive functions in both males and females.

Gastrin is a hormone produced by the stomach that stimulates the release of gastric acid, aiding in the digestion of food. It also plays a role in regulating the emptying of the stomach and the movement of food through the digestive tract. Abnormal levels of gastrin can lead to conditions like gastritis and peptic ulcers.

Progesterone. When the level of progesterone drops, it causes the uterus wall to begin contracting, which pushes the baby's head into the cervix, starting the positive feedback loop of contractions in labor.

No, biologically a person born male cannot conceive a child from a normal fertilization process. They do not have the reproductive organs necessary to carry or deliver a child.

Hormones are chemical substances that act like messenger molecules in the body. After being made in one part of the body, they travel to other parts of the body where they help control how cells and organs do their work. For example, insulin is a hormone that's made by the beta cells in the pancreas. When it's released into the blood, insulin helps regulate how the cells of the body use glucose (a type of sugar) for energy.

Growth can be manipulated in a way that growth hormone implants are used for people with pituitary problems. Steroids are used to make muscles bigger.

Calcitonin is released from thyroid gland in response to hypercalemia. On the other hand, parathyroid hormone- as you guessed - is from parathyroid gland in response to low levels of blood calcium. Which will cause calcium to be released from bone into blood to compensate.

The medical term for a hormone that stimulates contraction of the uterus during labor is oxytocin.

Iodine in Czapek Dox agar is added as a source of iodine for microbial growth. It is essential for the growth of certain fungi that require iodine for metabolic processes.

Antidiuretic hormone (ADH), also known as vasopressin, is responsible for decreasing urination by increasing the reabsorption of water in the kidneys, leading to concentrated urine and reduced urine volume.

the thinning of the cervical mucus is due to the estrogen spike prior to ovulation. This is caused by the primary oocyte signaling the anterior pituitary gland that it has matured and is ready for release.

If you have been diagnosed with all types of thyroid problems, it is essential to work closely with your healthcare provider to explore treatment options carefully. Your provider may recommend a combination of medication, lifestyle changes, and possibly surgery depending on the specific thyroid issues you are facing. It's important to stay informed about managing your condition and follow your healthcare provider's recommendations diligently.

Radioactive iodine treatment involves ingesting a radioactive form of iodine that is absorbed by the thyroid gland. The radiation emitted by the iodine destroys thyroid cells, which can be beneficial for treating conditions such as hyperthyroidism and thyroid cancer. It is a common and effective treatment option with low risks and side effects.

Thyroid hormone, specifically triiodothyronine (T3) and thyroxine (T4), are the principal hormones responsible for increasing the metabolic rate in body cells. They regulate cellular metabolism by influencing the consumption of oxygen and nutrients needed for energy production.

The ICD-9 code for hormone imbalance depends on the specific hormone involved. For example, the ICD-9 code for hypothyroidism is 244.9, while for hyperthyroidism it is 242.9. It is important to consult with a healthcare provider for an accurate diagnosis and corresponding ICD-9 code.

Yes, oxytocin plays a key role in milk ejection during breastfeeding. When a baby suckles, oxytocin is released from the brain, causing the muscles around the milk-producing cells to contract and push milk into the ducts for the baby to feed on.

When additional adrenaline is released, body functions such as increased heart rate, elevated blood pressure, dilation of air passages in the lungs, increased glucose release from the liver, and improved blood flow to muscles are typically observed. These changes are part of the "fight or flight" response to help prepare the body to respond to perceived threats or stressors.

This type of stimulus is called hormonal stimulation. It occurs when one hormone signals another endocrine gland to release its own hormone to regulate physiological processes in the body.

No, hormones of the same chemical class can have different functions in the body. While they may share similar structures and signaling pathways, their specific targets and effects can vary depending on the tissues and organs they act on.

According to Wikipedia the thyroid gland, the pituitary gland, and the pancreas are part of the endocrine system. The main function of these, and other glands within the endocrine system, is to secrete hormones into the blood.
