The Hypothalamus : Human Body 's Internal Balance System

In the article “This is your Brain…” by Roy Wood and Patrick Barker is about understanding the brain and the limitations that the brain has. That the brain controls our body and everything that happens in our body. That there is so much more that the brain does then we ever give it credit for. The brain has three important things the bad attributes, the neocortex and limbic system, and the manages energy.

Notably, the human brain plays a key role in how we feel or respond to situations around us. Neural circuitry and the transmission of neurotransmitter play a key role in emotion, rewards and aggressive behavior. These circuitry is inborn and exist in every human being. Aggressive responses by Grendel’s mother to the cry of her son to free him from his ordeal are because of inner workings within and around her brain. According to a human research carried out by Mary E. Braine, “The hypothalamus plays a critical role in the physiological responses through both integration and output of human responses. The hypothalamus controls the autonomic nervous system and thus is key in generating the physiological

The medulla processes your swallowing along with your digestion from the lunch you had an hour ago, but it also is helping your heart and helping you to keep breathing while you are on your journey to another class. But the one of the main reasons you are even alert enough to perform this task is because your Reticular formation is sending signals to keep you alert. Everything that you see, feel, hear, or touch on the way to class is only processed because of the Thalamus, as it interprets how you feel these certain things, like a chill in the air or maybe the rain that could be falling. The thalamus also helps you with staying conscious on your trek across campus. But one of the reasons you feel good enough at school has something to do with the hypothalamus, as it links your nervous system to the endocrine system and helps regulate your temperature, and your hunger along with other hormones in the body. It also helps in growth and development, but most of us making this journey are probably done growing. But if you’re hungry while walking across campus it could be the regulation of your metabolism at work, which is also a job of the

The Hypothalamus receives input form the body and the brain and then sends its influence to the out to the entire body, affecting and regulating things such as body functions, body rhythms, and behavior motivations.

Imagine a glass of water; it's filled half way. Instead of worrying whether it is half full or half empty, worry more on how much it weighs, yet the actual weight doesn’t matter. What really matters is how long one holds it. If one were to hold it for just a minute it would feel very light. If one was to hold it for an hour, they’ll have an ache in their arm. Now, if one were to hold it for a day, their arm would feel numb and paralyzed. In each case, the weight of the glass didn’t change, but the longer one held it, the heavier it became. The stresses and worries in life are like that glass of water. Carry them for a short while and they're manageable. Worry about them a bit longer and they will begin to hurt. And if we to think about them

The brain resides in the cranium, and is a perplex organ of several tissue layers and neural networks (Tang-Schomer, et al., 2014). Some parts of the brain include the cerebral cortex and thalamus, which support cognition and relay signals, respectively. Furthermore, the brain is responsible for both autonomic and somatic bodily mechanisms (OpenStax College, 2013). Considering the diversity of structural functions within the brain, the brain’s overall function is an executive one that controls the nervous system by means of perceiving and communicating electrical signals.

Functional Hypothalamic (FHA) is a reproductive disorder in which secondary amenorrhea occurs, due to decreased Gonadotropin releasing hormone (GnRH) pulse secretions. It is characterized by hypercortisolism, hypogonadism, lower leptin levels, and dysregulated thyroid function (Berga and Loucks 2007). There are three types of FHA categorized as either weight loss-related, psychological stress-related, or exercise-related amenorrhea. In each, higher than normal levels of cortisol caused diminished functional activity of the ovaries, leading to deficiency in estrogen.

Today most of us are aware that there is a close connection between how our brains function and how we behave in daily life. Our brain, which has developed throughout life based on individual and shared experiences, impacts everything from our personalities to our senses to which professional roles best suit us. Our brains also regulate systemic functions like breathing and how we respond to pain. One area of the brain, the pituitary gland, regulates many of the hormones our bodies need to function normally. While they have not always been seen as inseparable, the sciences of neuroanatomy, neurophysiology and neurology are increasingly intertwined with areas of the social sciences - particularly cognitive psychology - which deals with how we process information. The combination of these once distinct disciplines, all related to the myriad functions of the human brain, have converged as a multi-disciplinary field known as neuroscience.

The brain is vital to the functioning of every human being. After studying the brain for a whole semester, it made me realize how important it is to keep the brain health and protected. God made human being very complex, and trying to understand how each organ relates to each other has been a challenge for anyone in the medical field. Each year, new techniques are discovered as to what, where and how the human brain operates. There are discoveries made in the medical field everyday that were not known before. The brain is the part of the central nervous system that encompasses the cranium that consist of the forebrain (prosencephalon), the midbrain (mesencephalon) and the hindbrain (rhombencephalon). If the brain is damage due to an acquired brain injury, it can

The central nervous system is composed of our spinal cord and brain which consistently controls our mind and behavior. The complexity of our brain is not entirely deciphered, but with extensive scientific research it can be concluded that each specific section has its own specialized function. In reference to eating pizza, socializing, and playing a game of cards, it can be deduced that our central nervous system is always critically analyzing data using our Broca’s area for speech, hippocampus for memories, hypothalamus controlling internal body, and occipital lobe organizing visual stimuli.

The brain is an amazing thing. It is the control tower of the human body, controlling everything from our thoughts to our actions to keeping us breathing and everything in-between. Scientists and researchers are always learning new and interesting things about the human brain. Consider these three recent Brain News studies:

The hypothalamus is a small cone-shaped structure (Benson, 2016); it is a portion of the brain containing a number of small nuclei with a variety of functions. The hypothalamus has considerable functions of linking the nervous system to the endocrine system via the pituitary gland also called hypophysis. The location of the hypothalamus is directly below the thalamus and is part of the limbic system (Benson, 2016). In the human body, the hypothalamus controls some of the metabolic processes including some other activities of the autonomic nervous system (ANS). All vertebrate brain contain a hypothalamus. The most significant effect of injuries to or abnormalities in the hypothalamus on behavior are the changes in the individual’s digestive

Stress is a part of our daily lives but our body has a mechanism that keeps us at homeostasis. The Hypothalamic-Pituitary Adrenal Axis (HPA) maintains and controls our response to stimuli that disrupts this mechanism. From the periventricular nucleus in the hypothalamus, corticotrophin releasing hormone (CRH) is released traveling to the anterior pituitary through the hypophyseal portal vascular system. This triggers the releases of adrenocorticotropic hormone (ACTH) which travels to the adrenal cortex and stimulates the release of cortisol. Once the balance is restored, negative feedback inhibits the release of the hormones (Figure 1). If stress is prolonged and the levels of cortisol or CRH remain high this balance can be disrupted causing a maladaptive response or allostatic load. This can lead to emotional disorders like depression and anxiety, heart disease, and diabetes.

The limbic system contains many unique structures, the hypothalamus being the primary output structure, because it is connected to the frontal lobes, septal nuclei and the brain stem. The hypothalamus is located at the optic chiasm, and connects the limbic system and the autonomic nervous system. Many different biological inputs influence the endocrine functions of the hypothalamus. The body and changes in the body act as an input system for the hypothalamus. Temperature, osmolality, glucose, and sodium concentrations act as internal sensors that signal the function of the hypothalamus. Inputs are received through the fornix and the amygdala pathways which are also important in facilitating hypothalamus function. The hypothalamus is necessary in mediating
