removal of a signal-peptide sequence during translation. A cultivator of several hormones, POMC is synthesized in the pituitary gland. After separation by enzymes at various points, it can produce Beta-Endorphin (a neuropeptide produced by the hypothalamus and pituitary glands, and a neurotransmitter that is released when the body experiences stress or pain), and Adrenocoticotropic Hormone (ACTH). The POMC gene is located on chromosome 2p23.3, and it is expressed in the pituitary gland. This gene

axis is gonadotropin-releasing hormone (GnRH); this hormone is produced by neurons of the preoptic and arcuate nucleus of the hypothalamus. The hormone is released into the hypophyseal portal system, and stimulates the pituitary follicles, which encourages hormone secretion. This in turn encourages the secretion of estradiol and progesterone by the ovaries. The hypothalamus-pituitary-adrenal axis (HPA) is part of the stress response system, and has the effect of changing the organism's behavior in

the hypothalamus, however the balance of heat produced and heat lost maintains a constant body temperature. Above in diagram 1, the flow of how Thermoregulation works to make changes in temperature for the body is shown. In human being body temperature is controlled by the thermoregulatory center in the hypothalamus. The hypothalamus activates one of several mechanisms to either increase or decrease your temperature. (Biology Reference, 2014) When the body needs to cool down the hypothalamus tells

stimulation of the hypothalamus induces panic attacks in both human subjects and laboratory animals (Schmitt et al., 1983). Specifically, the dorsomedial hypothalamus (DMH) has been implicated in the modulation of autonomic, neuroendocrine and behavioral responses and in the modulation of pain (Biagioni et al., 2013). The expression

People often exercise in elevated temperatures and maintain an intense work-out to improve their maximum conditioning levels. Participating in such exercise challenges the homeostasis of the human body. The way that the body reacts and adapts to physical stress depends on various components. Specifically, exercising in the heat can overload the body and decrease its capability to adapt to the stress that it is being put through (Nielsen, Hales, Strange, Christensen, Warberg, & Saltin, 1993).

is the endocrine system. The endocrine system is the collection of glands of an organism which secrete hormones directly into the circulatory system, which then distributes the hormones to specific organs. The main endocrine glands include the hypothalamus, pituitary gland, pineal gland, thyroid gland, parathyroid glands, adrenal glands, pancreas, gonads(testes, ovaries) and thymus. Each have specific operations that they complete which make us function properly. The study dealing with the endocrine

1. The process where a cell passed its DNA sequence onto another cell is known as DNA replication. This process usually took place in the S phase cell cycle through mitosis where the copy of DNA molecule are segregated and cytoplasm open up leading to cell division. In order for the process to happen, an enzyme helicase must hack the hydrogen bond where the DNA “unzip” and “unwind” to establish two open template. DNA polymerase then replace the RNA primer by adding new complementary nucleotides to

The full fetal hypothalamus-pituitary-adrenal cycle is immature at the time of birth, so until that becomes functional, the glycogenesis process occurs. This process augments the conversion of lipids from fatty acids (lipolysis) and ketosis, which competes with how the normal

A neurotransmitter is a chemical substance that is released in the nervous system at the end of the nerve fibers. Its release results in the transfer of impulses and information across fibers or other structure of the body. Dopamine is one of the neurotransmitters that are present in the nervous system. It is the neurotransmitter that is responsible for controlling the centers of reward and pleasure in brains of animals and humans. It is also responsible for making us acknowledge the presence of
