(Faravelli et al., 2012) and depressive disorders (Schatzberg et al., 2013). In patients with depression there is an increase of CRH mRNA (messenger ribonucleic acid) in the hypothalamus of patients with major depression (Raadsheer et al., 1995) as well as fourfold increase of immunoreactive IMMUNO REAC TO WHAT? neurons in the hypothalamus (Raadsheer et al., 1994). Major depressive disorder (MDD) patients also exhibit an increase in their cortisol response and a biological vulnerability for depression (Vreeburg

components of the Endocrine System The major glands of the endocrine system are the hypothalamus, pituitary, thyroid, parathyroid, adrenals, pineal body, and the reproductive organs (ovaries and testes). The pancreas is also a part of this system. Hypothalamus gland is located in the brain. The function of the hypothalamus is to regulate production of hormones in the anterior pituitary gland. Hypothalamus produces “releasing and “inhibitory” hormones. Pituitary gland located just below the brain

Mostly everyone enjoys food, it 's what brings people together. Lets face it, humans are always looking for a reason to eat. Our bodies need food in order to survive. However, at times we eat even when our bodies do not need it. This is the motivation of hunger. Hunger motivation refers to the need that humans have to eat in order to fulfill their hunger. Many factors other than surviving, can influence hunger such as psychological, environmental, and biological. Why do we eat? It’s clear to say

The nervous system and endocrine system work together to influence the behavior of humans. While the nervous system is a fast acting one, the endocrine system is a slow acting one that has a lasting effect. Growth Reproduction Metabolism Without the endocrine system there to help the nervous system maintain homeostasis none of the three things listed would be possible. The functions of the two systems together are quite amazing. Within the peripheral nervous system (PNS) is the autonomic

The point in the menstrual cycle where the FH and LSH levels are elevated is during ovulation. Ovulation begins approximately on the 14 of the menstrual cycle (Levay, Baldwin, Baldwin, 2015). According to Levay et al. (2015), ovulation is defined as the time in which the ovary releases an ovum. In particular, it is the ruptured follicle that releases that ovum. Right before ovulation, during the HPG feedback loop, the estrogen levels to go up and change the feedback from negative to positive. That

Homeostasis is a system to maintain a stable environment within an organism. An important example of homeostasis is the regulation of body temperature. There are two types of blooded organisms. The first type are warm blooded which are called endotherms and the second type are cold blooded which are called ectotherms. Endotherms are mainly organisms such as humans, mammals and birds. Ectotherms are mainly organisms such as reptiles, fish and insects. In terms of maintaining temperature , the difference

endocrine system is coordinated by the pituitary gland, which responds to information from the hypothalamus. The hypothalamus is a portion of the brain and is made of nervous tissue. It constantly checks the internal environment — that is, the conditions within the tissues, organs and systems of your body. If these conditions change, the hypothalamus responds.

The most important function of the hypothalamus is to link the nervous system and the endocrine system. It secretes hormones that act on the

gram. These parts are like the anterior and posterior pituitary, are two functionally distinct endocrine glands. Hypothalamus is taking control of both adrenal cortex and adrenal medulla. When the stress occurred, either emotional or physical trauma, prompts the hypothalamus to stimulate a part of the adrenal glands. The medulla and cortex secretes different hormones. The hypothalamus transmits nerve impulses that go through brain stem, spinal cord, and preganglionic sympathetic nerve fibers to adrenal

Question 1 a. According to McKinley, O’Loughlin and Bidle (2015), the replication of cells in the cell cycle included two general phases which are Interphase and Mitotic phase. As for the Interphase, the stage of preparation of cell division, it is normally divided into three phases which are G1, S and G2 phases and this process take approximately 23 hours. Firstly, G1 phase is the stage that the cell occurs growth and preparation for the S phase which is DNA replication. After that, DNA molecule
