Glands Essays

The mammary gland is composed of an outer layer of myoepithelial cells and an inner layer of luminal epithelial cells, which can be further categorized into ductal or alveolar subtypes. Stems cells are present in the basal position between the myoepithelial and luminal cells (Tiede and Kang, 2011; Figure 1c). At birth, the gland begins as a rudimentary tree occupying a small portion of the mammary fat pad and remains quiescent. With the onset of puberty, mammary gland morphogenesis is stimulated

What is the endocrine gland? What role does the pituitary gland have associated with the endocrine gland? Why is their negative feedback when the pituitary gland is controlling the action of another endocrine gland? Knowing and understanding the role of the pituitary gland will help you infer the negative feedback involved with the pituitary gland when controlling the action of another endocrine gland. Endocrine glands are hormonal glands that are part of the endocrine system (body's main system

feedback loops and the regulations of hormones. Before we can discuss why Eric is alive without a functioning pituitary gland we must first understand how the pituitary gland functions within the endocrine system. The pituitary gland is a pea sized gland that sits at the base of the brain and is attached to the hypothalamus by the pituitary stalk (infundibulum). The pituitary gland consists of two different portions, the anterior lobe and the posterior lobe. The anterior lobe is responsible for synthetization

An endocrine gland is a gland that comes from the endocrine system which secrets its products like hormones straight into the blood stream without passing through a duct, these endocrine glands are found in the pituitary gland thyroid gland testes ovaries pancreas adrenal gland, parathyroid gland and hypothalamus. (1)The two main classes of hormones are either steroids or modified amino acids, peptides and proteins. Adrenaline can effect a person’s body in different ways as it can cause a person’s

Hypothalamus Gland Hormones and Their Functions Katherine M. Gaub Western Dakota Tech Hypothalamus Gland Hormones and Their Functions The Hypothalamus gland is responsible for regulating certain metabolic processes and other activities of the autonomic nervous system such as, controlling the body temperature, hunger, thirst, fatigue, sleep, attachment behavior, and circadian rhythms. This gland, which is about the size of an almond, is located at the base of the brain and is near the Pituitary gland and just

IgA nephropathy is also known as Berger’s Disease, the disease was founded by Jean Berger a pathologist from France. In many parts of the world IgAN is also known as glomerulonephritis, which is a disease that damages the filtering units within the kidneys called the glomeruli, pretty much the disease itself causes the kidneys to completely destroy themselves 50% of the time. When an antibody called immunoglobin A lodges into the kidney over time this causes local inflammation that hampers the ability

Pheochromocytomas are a tumor that can be found inside the adrenal gland or on specialized cells of top of the adrenal gland. The adrenal glands are located on top of the kidneys and are responsible for releasing very high levels of epinephrine and norepinephrine. The inner area of the adrenal gland is called the adrenal medulla where the norepinephrine and dopamine are secreted by the cells. These cells are called catecholamine which is found inside the adrenal medulla. The catecholamine cells

Essay 89: Pituitary Gland Function The pituitary gland is a pea sized region of specialized endocrine cells and neurons located behind the optic chiasm and enclosed in a bony structure called the sella turcica, or Turkish saddle. Although the pituitary is often called the “master gland” of the endocrine system, that label is more appropriate for an adjacent area of brain known as the hypothalamus. As 19th century scientists deciphered the anatomy and physiology of the central nervous system

functions the bodies use of hormones. The body uses many different hormones and the endocrine system regulates these. When the glands of the endocrine system secrete the hormones, the hormones are put into the bloodstream to be sent to the different parts of the body. The glands that comprise the endocrine system are the hypothalamus, the pituitary gland, and the pineal gland which are all located in the brain, the thyroid, parathyroid, and thymus which are located in the throat, the adrenals and pancreas

To truly appreciate the thyroid gland, one must understand its importance in controlling metabolism, body temperature, and muscle strength. The thyroid is a butterfly shape gland that sits in front of the throat and it is part of the endocrine system. The thyroid gland produces hormones that influence every organ, tissue, and cell in your body. Such a small gland that controls so many functions in the body. The thyroid gland controls the body’s metabolism, this is how the body uses energy. Thyroid

hormones (Lurie, n.d). Cancer of any of these glands can result in the cancer producing hormones that can interfere with normal body function (Lurie, n.d). Cancer is the uncontrollable growth of malignant cells. Endocrine cancer can happen on any of the organs of the system and is more likely to affect women (Dr. Jemal, 2009). In the United States there is an estimated amount of 27,650 cases of endocrine cancer per year (A. Jemal, 2005). The glands associated with the endocrine system are the hypothalamus

tissue. Growth hormone is also affecting concentricity and memory. The release of growth hormone Hormones are substances released by glands in the body. Hormones get into the blood and are brought into the body through the blood where they perform their function. Growth hormone is released throughout the life of the pituitary gland. The pituitary gland is a small gland at the base of the brain. The release of growth hormone is not evenly distributed throughout the day. Growth hormone levels rise after

brain has many different parts that work together. We 're going to talk about these five parts, which are key players on the brain team: cerebrum (say: suh-REE-brum) cerebellum (say: sair-uh-BELL-um) brain stem pituitary (say: puh-TOO-uh-ter-ee) gland hypothalamus (say: hy-po-THAL-uh-mus) The Biggest Part: the Cerebrum Brain CerebrumThe biggest part of the brain is the cerebrum. The cerebrum makes up 85% of the brain 's weight, and it 's easy to see why. The cerebrum is the thinking part of the

People always want to present himself a little differently than others, various ways has been used by the people for showing himself attractive. Multiple types of hair styling are one of them. Hair can be classified straight_wavy_curly_kinky ext. from the view point of size it can be short, medium, and large. Multiple tools have been invented for various hair shapes. These are electronic device, hair clip, and cosmetic ext. When people go for party or special event he/she wants to change his look

Surgical Nursing, “Enlargement of the thyroid gland may happen because of increased TSH levels, or in response to the autoimmune process that occurs in Graves’ disease” (2015, Linda, S Williams, et al). According to the Mayo Clinic “Your thyroid is a butterfly-shaped gland located at the base of your neck just below your Adam's apple” (2014). If you can imagine how skinny your neck is, you can imagine how noticeable an enlargement would be. The thyroid gland is primarily controlled by a hormone called

INTRODUCTION The pituitary gland is a central endocrine organ that regulates basic physiological functions incuding growth, reproduction and metabolic homeostasis. It situates at the base of the brain, under the optic chiasm, inside a depression on the upper surface of the sphenoid bone, the sella turcica1 (Fig.1). Fig. 1 The pituitary is a small gland found inside the skull just below the brain and above the nasal passages, which are above the fleshy back part of the roof of the mouth

receptors are targeted toward.The major organs of this system are a host of glands, the pituitary, thyroid, parathyroid, adrenal, pancreatic, pineal, the female (ovaries), and the male

Addison’s Disease is a rare disorder where the adrenal glands, that’s located directly above the kidney, does not produce enough of the cortisol hormone. Addison’s disease can be separated into 2 sub conditions, primary adrenal insufficiency and secondary adrenal insufficiency. People with primary adrenal insufficiency suffer from both a lack of the aldosterone hormone and the cortisol hormone the adrenal glands produce. People with secondary adrenal insufficiency only suffers with a lack of cortisol

Endocrine system The main function of endocrine glands is to secrete hormones into the bloodstream. Hormones are chemical substances that effect the activity of another part of the body e.t.c organ. In one word, hormones serve as messengers, controlling and coordinating activities throughout the body. Fundamentally, hormones control the function of entire organs, affecting such processes as growth and development, reproduction, and sexual characteristics. Although hormones circulate throughout the

The PTH helps control the calcium and phosphorus levels in the blood stream. So, without the secretions of the PTH, the human body will slowly start to shut down. Consequently, the parathyroid hormone is not ‘awake’ like the rest of the body is. Hypoparathyroidism can be triggered by “something that develops in childhood” or the adult life (Hypoparathyroidism). It can even be congenital, meaning, someone can be born with this disorder, or it can be inherited (Hypoparathyroidism). A baby, if born
