Glands

(n.d.). Evaporation provides the major defense against overheating. The body’s surface contains approximately 2 million sweat glands. When the hypothalamus senses an increase in core temperature it will act by increasing blood flow to the skin, stimulating the sweat glands. The result is an increase in the rate of water loss through sweating which helps cool down (Vella, S, & Kravitz, n.d.). Physiology of Cardiovascular System Short-term: A physical…

every day to achieve the things that make you happy. Endorphins, serotonin, oxytocin and dopamine are released from the pituitary gland, which is located at the base of the brain. The pituitary gland is part of the endocrine system which is responsible for growth, reproduction, sleep, mood, etc. The pituitary gland is about the size of a pea and is known as the “master gland” since it controls many important functions in the body. Endorphins, also known as “feel-good” hormones, are associated…

triggered by prolonged use of medication such corticosteroids used for treatment of arthritis. Also, Cushing’s syndrome can be caused by tumor of pituitary or adrenal glands. The treatment would require the surgical intervention, the removal of tumor and possible long-termed use of medications in order to sustain normal function of removed glands. iii.) Positive feedback increases variable and boosting physiological processes. Figure 1 A flow diagram showing the positive feedback of the…

Some of these glands produce up to 2 secretions (Hormones) but mostly each gland will have the task of producing one. These glands are ductless, which is why they secrete directly into the blood. This is a list of the glands which are a part of this system; Pineal, Pituitary, thyroid, parathyroid, adrenal and parts of the pancreas, ovaries and testes. Digestive system…

A hot day, a workout, a nightmare, and the moments before a first date, all have something in common. The production of sweat. It is strange that sweat can be produced by these drastically different activities and moments, but, none the less, sweat is produced in each. Every action, situation, or time that a person sweats can be related to another time that a person sweats. Sweat is the single similarity between working out hard and laying in a bed all day eating cheetos. Furthermore, brain…

1. Explain the roles of hormones in sexual development. Hormones arouse cells and organs to specific activities and influence the way we look, feel, develop, and behave. 2. Describe the anatomy and physiology of the male and female reproductive systems. The visible part of the male sexual anatomy are the penis and the scrotum, the pouch that contains the testes. The testes makes testosterone and sperm. Immature sperm is stored in the epididymis. Inside the body are several structures involved…

condition that causes you to be in a wheelchair or being legally blind, but that’s not the case. One such condition that is not readily apparent that can qualify you to receive social security disability is parathyroid gland disorders. What is Parathyroid Gland Disorders Parathyroid gland disorders is an endocrine disorder, and your endocrine system is the one that handles the hormone levels in your body. This disorder has an impact in the level of calcium that is found within your body, and…

The Endocrine System controls bodily functions that tend to occur over a long time. Taking a similar role to the nervous system to keep the body in a state of homeostasis. Through the use of a negative feedback loop the Endocrine system insures the proper amount of hormone is in the body at any given time. These hormones serve functions from growth to balancing ion levels in the body. The Endocrine system is specifically down to the hormone meant for homeostasis. The Endocrine System is…

Adrenoleukodystrophy (ALD) is a condition which affects the ability of adrenal glands to produce adrenaline and myelin, which insulates the nerves in the brain and spinal cord. This diminishes the ability of the brain to communicate effectively with the rest of the nerves. This condition was initially identified in the early 1900s and was originally called Schilder-Addison disease (2). The cause of this condition originates in the peroxisomes, which are tiny structures in the cell which assist…

You can feel a rush of energy go through your body. Your hands start to shake, you are alert, the energy you have is through the roof. It’s called adrenaline. The hormone secreted by the adrenal glands, especially in conditions of stress, that gives you that extreme rush of energy that makes you feel like you can do almost anything. Most of the cases, when you get an adrenaline rush, are in fight or flight situations. The fight-or-flight response is a physiological reaction that occurs in…
