Insulin is produced by beta cells while glucagon is made byalpha cells. Glucagon along with epinephrine‚ GH and glucocorticoids are hyperglycemic hormone that raise the blood levels of glucose. 17.

HORMONES Hormones are a class of regulatory biochemicals produced in all multicellular organisms by glands‚ and transported by the circulatory system to a distant target organ to coordinate its physiology and behavior. They serve as a major form of communication between different organs and tissues. Hormones regulate a variety of physiological and behavioral activities‚ including digestion‚ metabolism‚ respiration‚ tissue function‚ sensory perception‚ sleep‚excretion‚ lactation‚ stress‚ growth and

Chapter 5 Notes * Dopamine and the related substances norepinephrine (NE) and epinephrine (EPI) comprise a small but important group of neurotransmitters and hormones called catecholamines. * Catecholamine contains two chemical similarities: a core structure of catechol and a nitrogen-containing group called an amine. The catecholamines‚ in turn‚ belong to a wider group of transmitter called either monoamines (transmitters that possess one amine group) or biogenic amines * EPI – adrenergic

As society continues on with the bustle of everyday life‚ stress continues to be a common factor that can negatively impact a person. Oftentimes‚ many people become sick due to a lagging immune system and must rest their bodies in order to recover. The same is true for a fetus in prenatal development. The mother’s stress levels do impact their child and can even go as far as impacting their child’s temperament. Child temperament is negatively impacted on prenatal stress due to genetic inheritance

Jorge Lozano Introduction Almost all living things have a normal daily cycle they adhere to. It usually relates to the pattern developed by a function of time in relation to behavioral and physiological processes. Circadian rhythm in all mammals is a process that describes our inner master “clock” and our daily functionality. “Circadian timing is structured in such a way as to receive information from the external and internal environments‚ and its function is the timing organization of the

Most psychoactive drugs affect a single type of receptor or neurotransmitter‚ i.e.‚ anandamide receptor for marijuana; endorphin receptor for heroin; or norepinephrine‚ epinephrine‚ and dopamine neurotransmitters for cocaine. Alcohol on the other hand interacts with receptors‚ neurotransmitters‚ cell membranes‚ intracellular signaling enzymes‚ and even genes (Fay‚ 1998). Since 80% of the alcohol drunk passes through

A carbohydrate is an organic compound that consists only of carbon‚ hydrogen‚ and oxygen‚ usually with a hydrogen:oxygen atom ratio of 2:1 (as in water); in other words‚ with the empirical formula Cm(H2O)n. The carbohydrates (saccharides) are divided into four chemical groupings: monosaccharides‚ disaccharides‚ oligosaccharides‚ and polysaccharides. In general‚ the monosaccharides and disaccharides‚ which are smaller (lower molecular weight) carbohydrates‚ are commonly referred to as sugars.
