Adrenal gland

Adrenaline is a hormone that the adrenal glands produce. They are produced during times of stress or excitement. This is a powerful hormone that is a part of the body's flight or fight response. It works by diluting air passages, contracting blood vessels and stimulating the heart. This helps supply the lungs with more oxygen and increase blood flow to the muscles. What Are The Adrenal Glands? The adrenal glands can be found above the kidneys. They are about three inches long. Adrenaline is one

Adrenal gland In mammals, the adrenal glands (also known as suprarenal glands) are the triangular-shaped endocrine glands that sit on top of the kidneys. They are chiefly responsible for releasing hormones in conjunction with stress through the synthesis of corticosteroids and catecholamines, including cortisol and adrenaline (epinephrine), respectively. Anatomy and function Anatomically, the adrenal glands are located in the retroperitoneum situated atop the kidneys, one on each side. They are

Adrenal Glands Adrenal gland is pyramidal shape gland situated above each kidney. They are consisted of two parts, which is adrenal medulla (internal part) and adrenal cortex (external part). Each gland only weight four gram. These parts are like the anterior and posterior pituitary, are two functionally distinct endocrine glands. Hypothalamus is taking control of both adrenal cortex and adrenal medulla. When the stress occurred, either emotional or physical trauma, prompts the hypothalamus to

There are two Adrenal Glands in your body. Each of them is located on top of a kidney. They’re name comes from exactly where they are located. The word ad means near or at and the word renes means kidneys. So when you put both words together it means “near or at kidneys.” Both Adrenal Glands are triangular shaped organs, and when measured is about one and a half inches in height and three inches in length. These small glands not only produce adrenaline, but several other hormones as well which are

activates its Autonomic Nervous System in an attempt to maintain homeostasis. The primary function is to regulate the stress response. The amygdala recognizes the threat and the hypothalamus controls the release of hormones from the pituitary gland. The pituitary gland can release hormones into the bloodstream that travel down to the kidneys and

for one ultimate purpose; to keep the body functioning properly. For years scientists have studied the components of the body, but sometimes research only leads to more questions. One of those questions being, What if people were born without adrenal glands? With the different mutations discovered in the human genes throughout the recent years, this could be possible. In fact, if this occurred, the body would not be able to regulate metabolism or maintain an internal balance between salt and water

that happens when the body senses danger or stress (3) (6). It is produced in the medulla of the adrenal glands (1) (3) (7) (8). The glands are right on top of the kidneys (5) (7). Adrenaline is then inserted into the bloodstream (6). Adrenaline is a hormone (5). It is known as the fight or flight response (1) (3) (7). When the stressful or dangerous situation occurs the brain tells the adrenal glands to start to produce adrenaline

it stimulates sweating or vasodilation to cool down. Whereas an endocrine organ, the hypothalamus is involved with the pituitary gland. Hormones such as Gonadotropin-releasing hormone, anti-diuretic hormone or corticotrophin hormone are all secreted by the hypothalamus. The release of hormones means it may lead to inhibiting or releasing hormone from the pituitary gland. The hypothalamus is able to work things between the anterior and posterior pituitary due to

1. The process where a cell passed its DNA sequence onto another cell is known as DNA replication. This process usually took place in the S phase cell cycle through mitosis where the copy of DNA molecule are segregated and cytoplasm open up leading to cell division. In order for the process to happen, an enzyme helicase must hack the hydrogen bond where the DNA “unzip” and “unwind” to establish two open template. DNA polymerase then replace the RNA primer by adding new complementary nucleotides to

Obviously, whether we want or not, stresses are happening everyday in our life. They can come from the external impact like an exam is coming, to the internal impact as pressure from yourself to achieve an A score; or from a small problem with low intensity like a traffic jam on the street, to a big issue with high intensity like being in a huge terrorism. It seems that we cannot run away from stress, it is something irresistible that we have to accept. Because stress is unavoidable, we need to learn
