Hypothalamus College Essays Samples For Students

The human body consists of trillions of cells that work together synchronously for the maintenance of an organism. The metabolic needs of all the cells in the body are almost similar. For the well-being of a human body and the proper functioning of all the cells, constant internal environment needs to be maintained by providing the cells with oxygen and nutrients (Homeostasis and Regulation in the Human Body < OpenCurriculum, 2016)
The internal environment of the body is tissue fluid, which bathes all cells making up the body (Mader, 2016). The composition of the tissue fluid must always remain ...

Abstract

The body has two main systems that are involved in the maintenance and reestablishment of homeostasis, nervous system and endocrine system. The endocrine system is made up of groups of organs that are involved in the production of chemical messengers known as hormones. Some of the major endocrine glands that are found in a human body include the hypothalamus, pituitary, thyroid, pancreas, pineal, gonad, adrenal, and pancreas glands. Although biological observations that are grounded in the functions of endocrine systems were noted by some of the ancient cultures, the modern understanding of various endocrine glands and the way they produce ...

Depression is a common disease which causes the patient to suffer from behaviors and thoughts which are negative and also by certain changes in bodily activities. These physical changes are called neurovegetative signs like body aches, crying spells, low libido, insomnia and weight fluctuations. There are different kinds of depressive disorders like manic depression, clinical depression, dysthymic disorder, postpartum depression, chronic depression and others. There are no specific causes of depression, it is caused by a combination of factors which are psychological, biochemical, genetic and environmental (Lunbeck Institute 2). It is therefore a complex disorder which has no specific treatment which is ...

Introduction

Cortisol is a steroid hormone produced in the adrenal glands located on top of kidneys and is usually released in response to particular circumstances and events, including acute stress and waking up in the morning. It significantly affects the body’s processes and helps its effort to maintain homeostasis (Aronson, 2009). It also plays a major role in human nutrition, as it helps regulate energy by determining which type of substrate (and which amount), protein, fat, or carbohydrate, the body needs to meet its demand efficiently. If cortisol stress hormone is increased for long periods of time and becomes chronically elevated, ...

The debate on sexual orientation has been going on for a long time in the world. There are many researches some claiming that the homosexual people are socially assimilated towards being homosexual from the social environment. There are others who hold to the opinion that it is entirely a hormonal aspect that develops as one grows. There are those who take a position in between the two and belief that gender and sexual orientation are as a result of the interplay between the environment and the genetic and hormonal state of the individuals. As it was learned recently, the hypothalamus plays an important ...

Introduction

The fight or flight response is one of the body’s autonomic defense mechanisms. This innate defense mechanism gets triggered whenever a person encounters a harmful entity or event, or basically anything that one may perceive as a threat to his survival. In such cases, the body’s hyper-arousal state which is characterized by dramatic changes not just in one but across all organ systems. The fight or flight response actually started as a simple theory by Dr. Walter Cannon. Dr. Cannon explained that any animal is subject to a reaction called fight or flight response which is characterized by a general and fast-acting discharge ...

It is well documented that human beings are capable of thriving and surviving in the harshest of conditions ranging from the arctic to the equator and with different forms of lifestyles and diets. One of the reasons’ for this is not farfetched, it is the ability of the human body to adapt to various conditions and in turn maintain homeostasis. Homeostasis refers to the human body's ability to regulate her internal environment physiologically in a bid to ensure and maintain stability in response to the instability and fluctuations of the weather and the external environment. Also, homeostasis refers to the ...

It is prudent to begin this discussion by pointing out that there is no definite definition for stress, either as a condition or a word. Therefore, its meaning depends on the context of use. Accordingly, this discussion focuses on stress as a situation that disturbs the equilibrium between a being and its environment; the feeling a being has that demands surpass its resources. This condition no doubt precipitates change in the body’s hormones serum level, as the body tries to respond or protect itself from the stressful stimuli. The most common response is the increase in the levels of hormones, which is geared ...

Hypothyroidism is an endocrine disorder that results from thyroid hormonal deficiency. In the U.S. and other regions that have sufficient iodine consumption, autoimmune thyroid or the Hashimoto disease, normally causes hypothyroidism, while worldwide, iodine deficiency is the leading cause.

Pathophysiology

Hypothyroidism can be caused by malfunctioning of the hypothalamus, thyroid, or pituitary gland, as all of these result from the same “negative feedback mechanism” (McCann, 2011, p. 496). Despite belonging to the same mechanism the hypothalamus malfunction rarely causes hypothyroidism, and when it does, it is called ‘secondary hypothyroidism’. While the malfunction of the gland is referred to as ‘primary ...

Black Cohosh

Black cohosh is also known as black snakeroot (as the name appeared in the U.S. Pharmacopoeia in the year 1820), bugwort, columbine-leaved leontice, tall bugbane, cordate rattle top, rattleroot, macrotys, papoose root, and battleweed. Its Latin name is Actaea racemosa or Cimicifuga racemosa. Macrotys actaeoides is also a synonym for the drug (Frostburg State University, frostburg.edu). It belongs to the Ranunculaceae (buttercup) family (Kinghorn A 2). The plant was first described in 1690 in Phytographia by Leonard Plukenet as Christopheriana facie. Later in 1751, it was named as Actaea racemosa by Linnaeus. However, the name was later changed into ...

In fact, there are considerable differences in physical activity, emotions, interests, perception between men and women. Numerous scientists have explored and discussed if these differences are conditioned by social factors or biology. To make it clear, some think that it is biology that defines human behavior, tastes, skills etc.; others adhere to the opinion that society is a more influential impact on formation of behavior. In other words, socially created features of men and women are called "gender", "sex" is determined by biology. Unfortunately, nowadays it is possible to see numerous mistakes and discrepancies concerning the use of both ...

What Makes the Brain ‘Tick?’

The human brain is a very complex organ that controls each and every function of the human body. Without its proper functioning and control, the body can suffer adversely. The brain makes decisions for the body, is responsible for making the personality of a person, helping in making judgments and preserving the memory of the person. Moreover, the human brain is also responsible for the abstract concept of thinking that cannot be defined very accurately. Yet every person with a normal brain has a strong thought process.
There were many things that were unknown to me before going through ...

Genetic Research

Features genetics homosexuals have been studied little. Scientists are searching for the gene or genes of homosexuality since the 1980s. As in many other studies, trying to distinguish the symptoms of congenital acquired an important material has been obtained from the analysis and relatives, especially identical twins. It has been shown frequent presence of homosexual men several older brothers, and of manifestations of homosexuality in both identical twins, even in cases where they were brought up separately.
According to the research, if identical twins homosexual men, the chances are that he will be inclined to homosexuality, is 52%; ...

Renal compensatory mechanisms

Severe anemia causes the redistribution of blood supply to vital organs such as the brain and heart. This results in a decrease in renal blood flow causing the activation of the renin-angiotensin-aldosterone-system. Activation of this system results in increased production of aldosterone by the adrenal glands. Aldosterone causes increased retention of salt and water by the kidneys. This compensatory mechanism increases blood volume and renal blood flow without altering tissue hypoxia in other organs (Gaspad, 2005 as cited in Coyer & Lash, 2008).

Pituitary gland

The decrease in renal blood flow also stimulates the production of anti-diuretic hormone which increases ...

Theories of Emotion

Darwin’s Theory of the Evolution of Emotion

This theory posits that specific emotional responses, such as human facial expressions, are associated with the same emotional states in all members of a specie (Pinel, 2009). Darwin asserts that just like behaviors, the expression of emotions resulted from evolution where the natural selection process caused the development of the brain mechanisms that are responsible for emotions and motivation (Nesse & Ellsworth, 2009).

James- Lange Theory

This theory suggests that the sensory stimuli that induce emotion are received and interpreted by the cortex, which causes changes in the visceral organs in the skeletal muscles via the ...

a) Explain why the effort of hormonal (Endocrine ) control tends to be slow whereas nervous control is usually very fast.

Endocrine control is normally slower when compared to nervous control majorly because hormones once released by the endocrine gland have to travel via the circulation to reach their target receptors on the effector organ which generally takes more time. Meanwhile, information relayed by nerves is in form of impulses (that is, action potentials generated due to electrical excitation produced by a change in the charge across the surface membrane of the neuron evoked by the stimuli) that simply travel along the ...
