Endocrine System Essay

regulated by hypothalamic releasing and inhibitory factors delivered via portal capillaries, and by negative feedback inhibition of the cognate hormones produced by target endocrine glands such as the thyroid and adrenal cortex (Lewis, 2011). Etiology The pituitary regulates and controls the secretion of hormones from other endocrine glands, which in turn regulate many body

Graves Disease In the 19th Century (1801 – 1900) Robert Graves discovered Graves’ disease and that’s why its named Graves disease. Graves' disease is an auto immune system disease that affects the thyroid. It is due to an abnormal immune system response that causes hyperthyroidism which is when the thyroid gland to produce too much thyroid hormone. The most common cause of hyperthyroidism is Grave’s disease. The thyroid is a small butterfly shaped gland in the front of the neck. It makes hormones

To get a clearer picture of how Cialis work, let’s focus on how penile erection occurs. Following a sexual stimulation, the nervous system around the erectile tissues triggers the release of nitric oxide (NO). The NO activates an enzyme known as cyclic guanosine monophosphate (cGMP) that relaxes the smooth muscles of the penis, allowing blood to flow in. An erection results when the

Cortisol is a cholesterol derivative steroid hormone. It is produced in the cortex of the adrenal gland. Cortisol is secreted because of stress related events and its part of our adaptive stress response. The total plasma cortisol taken in the morning, in a healthy individual is 200 – 700nmol. Secretion of cortisol follows the diurnal rhythm so naturally levels of cortisol are at their highest 20 – 30 minutes after awakening; with an average of 50% increase. This is referred to as the cortisol awakening

stress. Although the adrenal gland is the most common area of the body neuroblastoma begins at, the tumour may also grow and spread to other part of the body, such as the bones, liver, and skin. The tumour is spread through the blood and lymphatic system. The adrenal gland has two part of the organ which consist of the outer cortex and the inner medulla. The cortex is the main part of the adrenal gland and the medulla is about ten percent of the adrenal gland. The cortex is divided into three zones

Aldosterone and Hormone Replacement Therapy Aldosterone falls in the class of hormone called mineralocorticoids, produces by the adrenal glands and is found near the kidneys. It sustains blood pressure, water and salt balance within the body. This procedure is assisting the kidneys to preserve sodium and excrete potassium in order to maintain a balance. If Aldosterone production falls, there isn’t enough regulation of salt and water balance (as aldosterone is being lost through urination) triggering

As midwives and nurses who help pregnant mothers, we shouldn’t be shocked by this physiological response. It’s also worthy to note that during labour and birth, the woman’s body also produces oxytocin (via the parasympathetic system), which helps to induce normal labor in conjunction with a calming effect. Where does the oxytocin come from? This naturally occurring calming chemical is produced by the hypothalamus and secreted through the back part of the pituitary gland. The

The point in the menstrual cycle where the FH and LSH levels are elevated is during ovulation. Ovulation begins approximately on the 14 of the menstrual cycle (Levay, Baldwin, Baldwin, 2015). According to Levay et al. (2015), ovulation is defined as the time in which the ovary releases an ovum. In particular, it is the ruptured follicle that releases that ovum. Right before ovulation, during the HPG feedback loop, the estrogen levels to go up and change the feedback from negative to positive. That

this disease was named after, first noticed Graves’ disease in a patient during 1835. However, no one knows what exactly caused this disease; it causes the thyroid gland to produce too much thyroid hormone (hyperthyroidism). In which your immune system then creates an antibody that causes the thyroid to grow and make more thyroid hormone than your body needs. Graves’ disease is a genetic condition that affects women more than men. Thyroid hormone production is regulated by a hormone called thyroid

The patient’s diagnosis is primary overt hypothyroidism. The patient presents with certain features such as weight gain, weakness, excessively dry flaking skin, dry hair, sluggish movements, constipation, bradycardia, diminished deep tendon reflexes, and bilateral edematous hands, which is classical signs and symptoms for primary hypothyroidism. The patient laboratory test reveals she has an elevation in serum thyroid stimulating hormone level along with low serum free thyroxin and triiodthyronine
