Hypothalamus

Question 2: Define the term hypothalamus. The hypothalamus is an area of the brain that is notified of any imbalances occurring in the body and allows bodily processes to bring equilibrium. Question 3: State the function of the hypothalamus. The hypothalamus is the part of the brain notified by receptors of an occurring imbalance in the body temperature and triggers reactions to overcome or counteract the change. Question 4: Describe the process of homeostasis.

more than just a kiss: A Neurobiological Perspective on Love and Affection”, oxytocin, vasopressin, and dopamine are just a few of the neurotransmitters that release chemical responses in the brain when love occurs. Oxytocin is in nuclei of the hypothalamus and releases into the circulation by the pituitary gland (Boer, Buel, and Horst). Oxytocin plays an important role in pair bonding and romantic love. It encourages cuddling between lovers and increases pleasure during lovemaking (Chapman). Furthermore

the adrenocortical response, is controlled by the sympathetic nervous system; and the other is the adrenomedullary response which is controlled by the hypothalamus - the part of the brain that triggers the release of different stress hormones - and pituitary gland (Lovallo, 2015; Sarafino & Smith, 2011). In the adrenocortical response, the hypothalamus sends a message to the sympathetic nerves that is mediated by the brain stem, this in turn activates the adrenal medulla which secretes epinephrine (adrenaline)

Structures of the Brain The Brain Stem The brain stem or the medulla is the closest to the spinal cord. The brainstem is responsible for most of the human bodily functions. The brain stem is critical for human survival and normal human functions. The brain stem is also responsible for information of pain and touch from the head and neck; it is also responsible for the inputs from the face and the mouth. Reticular formation is a group of neurons, nuclei, that are important for sleep and wakefulness

Both the autonomic nervous system and the endocrine system help to maintain homeostasis within the body. They work together to affect multiple bodily functions, including reproduction, growth and metabolism (Patel, 2014). The hypothalamus is a gland that connects the autonomic nervous system and the endocrine system. It links the two systems together. It receives messages from all over the body and is responsible for coordinating with the autonomic nervous system to make necessary changes (Martini

Question 1: a) The two processes, with which a cell passes this DNA sequence onto other cells, are DNA replication and mitosis. The cell cycle is inclusive of mitosis and DNA replication, the latter of which occurs in the S phase (synthesis) of the cycle. The goal of the S phase is to create two identical semi-conservative chromosomes. The enzyme helicase unwinds the parental DNA double helix strand and uses it as a template so the enzyme DNA polymerase can attach free-floating nucleotides to the

The hypothalamus will send a signal to the pancreas to release glucagon, the hormone responsible for increasing glucose, to the blood. After glucagon enters the blood it will go to the target cell to bind to the receptor. After it reaches the receptor, glucagon

Winn, 1995), which proposed the idea that there were two specific centres in the brain, the lateral hypothalamus, and the ventromedial nucleus of the hypothalamus, of which decreased the experience of hunger (Anand & Brobeck, 1951) and increased the experience of hunger (Brobeck, Tepperman, & Long, 1943) respectively, was discredited with the discovery of the paraventricular nucleus of the hypothalamus. The paraventricular nucleus was found to stimulate eating after it had been injected with various

overheat/sweat or a blood glucose level dropping due to missing a meal. Luckily, there are body systems that work together to bring the internal environment back to the right balance. The nervous system and the endocrine system are linked with the hypothalamus, which is situated in the centre of the brain it provides the needed corrective measures to ensure the body is back to the right balance. When homeostasis is maintained, we know that the body is healthy. The nervous system maintains homeostasis

(McKinley, O'Loughlin, & Bidle, 2013). The endocrine system works to control and regulate the body. It works by hormones being released into the blood and carried to target cells and tissues. The control center of the endocrine system is the hypothalamus. The hypothalamus has direct control over the pituitary gland
