Hypothalamus

mass of every adult is composed of water. Most of us could survive without food for weeks on end, but would die after only three days or so without water. Indeed, if we go for very long at all without water, that part of the forebrain known as the hypothalamus triggers the thirst response, and we seek water with increasing urgency. Almost as important is the utility of water for washing: several crucial activities, such as eating, and many other enjoyable activities demand at least a modicum of…

The endophyrne hormone are small protein chains that are released through the spinal cord and the bloodstream. The mind produces at least 20 different types of endorphins, which are stored mainly in the hypothalamus. Its function is to reassume ourselves with a pleasant sensation when we do something convenient for our body. Example practice sex, exercise or being accompanied, motivating us to continue looking for that feeling by practicing these beneficial…

Glucocorticoid are primarily used therapeutically as anti-inflammatory and immunosuppressive agent. They are secreted from the adrenal cortex of the adrenal gland in a circadian manner or in response to stress perceived by the brain. They are able to modulate physiological homeostasis and coordinate those adaptive responses to stressors. An imbalance in glucocorticoid levels, specifically chronic glucocorticoid has been associated with a number of neuropsychiatric disorders, specifically…

Case study one – (Explain how the musculo skeletal system structure is suited to the function it performs. (2.1) Mrs C is pregnant and wants to pick up a ball, describe in depth which parts of the musculo skeletal system are involved in this movement and which structural parts provide support and protection of the vital organs. The musculo skeletal system consists of bones of the skeleton, muscles, cartilage, tendons, ligaments and joints, they all work together to provide the body support,…

Hypothyroidism You sleep eight hours a night, but you still feel sluggish. You haven’t changed your diet, but you’re gaining weight. To top it off, you’re feeling achy and depressed. It’s easy to blame these symptoms on a busy lifestyle or advancing age, but for mil- lions of people — especially women — your thyroid is the culprit. Hypothyroidism develops when your thyroid isn’t producing enough thyroid hormone. What Is Hypothyroidism? Millions of people suffer from some form of…

pregnancy category X and should not be taken during pregnancy (Medscape, n.d.). The mechanism of action for phentermine is that it is a sympathomimetic amine, which inevitably induces an anorectic like effect by releasing norepinephrine within the hypothalamus (Medscape, n.d.). The mechanism of action for topiramate is that suppresses the appetite by inhibiting AMPA/Kainite excitatory glutamate receptors and regulates voltage-gated ion channels (Medscape, n.d.). Initial renal monitoring is…

Cluster Headaches: Medicine’s Mystery Malady In The Beginning Humankind has always suffered from headaches. The first written records discussing cluster headaches were in the mid-1600s. At that time the headaches were described by the intensity of the pain or given the name of the author describing them. Wilfred Harris, a British neurologist, was among the first to accurately describe the episodic nature of the headaches. Later, in 1939, Dr. Bayard Taylor Horton, a US neurologist, further…

contributing to homeostasis in the body. This is one of the most important glands in the human body. This gland produces certain hormones such as adrenaline and the steroids aldosterone and cortisol. When cortisol concentrations in the blood are low the hypothalamus secretes corticotropin-releasing factor (CRF). CRF is released, stimulating the anterior pituitary to produce adrenocorticotropic hormone (ACTH) which, in turn, stimulates the adrenal cortex to release cortisol into circulation. When…

In support of Patricia S. Churchland’s neurophilosophical argument that the brain/mind is our self, I will further argue that our various brain structures, functions, and the related body systems contribute to the important expressive aspects of the self, giving self its valued, unique identities. In her book, Touching a Nerve: The Self as Brain, Churchland uses a map analogy to introduce the brain’s relationship to the self. Although the brain creates a map that “constitutes a representation of…

The nucleus accumbens is the release sight for the neurotransmitter dopamine, a nature chemical in the central nervous system. When released in standard quantities, it assists in critical brain functions. Like most neurotransmitters, dopaminergic signaling entails an equilibrium between dopamine release and the re-uptake by presynaptic nerve terminal. Under specific circumstances, a stimulus will promote the release of dopamine into the synapse. Dopamine transporters will then remove the…
