Hypothalamus

brain, and is about the size of a kidney bean. The hypothalamus regulates our autonomic nervous system (also known as the ‘fight or flight’ response). It does this by regulating the release of hormones, the effects of which include control of heart rate, breathing, digestion, and blood pressure, among other things. The hypothalamus also controls the pituitary gland, which releases hormones that regulate growth and metabolism. The hypothalamus receives input from many different sources, so…

you urinate. ADH is made in a part of your brain called the hypothalamus, and then is stored and released by the pituitary gland. When you don 't have enough fluid in your body, ADH is released and your kidneys keep the extra fluid instead of releasing it into your bladder. In central diabetes insipidus, the pituitary or hypothalamus is damaged, resulting in issues with the release and/or production of ADH. The pituitary and/or hypothalamus can be damaged due to tumors, head injuries, brain…

Evaluate the biological basis of aggression. To what extent can human aggression be controlled by biological intervention? Aggression is associated with anger as usually aggressive behaviour is acted upon when a person is angry or upset. Anger is a normal human emotion and it’s a natural response to threatening circumstances that may create aggressive feelings or the fight or flight response. When anger isn’t kept under control a person may become hostile. People have to express their anger and…

There are five characters in the play “ The Woman’s Menstrual Cycle”: Pituitary gland which is a little gland that is behind the eyes Hypothalamus area of your brain above the pituitary gland Ovary glands, which are two glands on the left and right side of the lower abdomen that are close to the fallopian tubes Follicles that contain eggs Uterus a pear-sized muscle that is between the bladder…

that contains sensors that monitor body temperature is the hypothalamus. 10. a) Two mechanisms the body uses to cool itself are the blood vessels dilating to radiate heat, and sweat glands increasing to increase sweat production. b) Two mechanisms the body uses to heat itself are the blood vessels constrict, reducing heat, and muscles beginning to shiver, generating heat. 11. a) The signal in the feedback loop would be the hypothalamus sensing that the body temperature is too high sending…

to certain cards or even how you yourself should act in a friendly card game. The Hypothalamus is what is keeping you awake and alert during the party. The pizza at the party is there to meet your Hypothalamus needs because it controls your appetite, and without any food during the party, the system may be beyond capable of functioning. During long periods of time, everyone usually gets tired, but the Hypothalamus, during this party would keep you awake and prevent you from falling asleep.…

certain parts of my brain are involved which allow me to perform properly. The limbic system comprises of the thalamus, hypothalamus, hippocampus, amygdala, and the cingulate cortex. In general, the limbic system is involved in emotions, motivation, memory, and learning. However, as I eat pizza, socialize, and play cards, I am primarily using the hippocampus and hypothalamus parts of my brain. To begin with, the hippocampus is located within the medial temporal lobe on each side of the…

A) The movement of neural impulses down the body of an axon When Mr. Cava is scratched on the nose by a minion, the nerve endings underneath his skin pick up the stimulus and a process begins. Next, an impulse in sent towards the brain telling it what happened. The impulse travels through axons, which connect cell bodies to muscles, neurons, or glands. This process occurs over and over, and is sped up by the use of the myelin sheath. The myelin sheath speeds up the movement of neural impulses in…

Paul Pierre Broca talked about ‘le grand lobe limbique’ in 1878 or the great limbic lobe and used the term “limbic” (from the Latin limbus for border) to the rounded rim of the cortex which also has the cingulate and the parahippocampalgyri. However, its supposed role in emotion was elaborated by the American physician, James Papez in 1937 in the influential paper titled ‘A proposed mechanism of emotion’. This anatomical model is called the Papez circuit.[2] In the year of 1948 scientist…

that the INAH 3 found on the hypothalamus is somewhat different in homosexual men and women when compared to heterosexual men and women. He states that INAH 3 is typically larger in men as opposed to females whereas in homosexual people the opposite typically happens. Animal experiments have proven that this area is what regulates sexual behavior. Dr. LeVay also discussed experiments done on homosexual sheep that proves his hypothesis is with merit. The hypothalamus of gay sheep was examined and…
