A couple examples include human growth hormone and follicle stimulating hormone. Human growth hormone regulates the growth and metabolism of the body. Follicle stimulating hormone stimulates the production of sperm in the body. b. Identify the following.
According to Nevid (2008) in his book, Psychology: Concepts and Applications, the biggest argument related to gender identity is the nature versus nurture, the role played by hereditary and environmental factors as well as their relationship to gender identity. In addition, there is evidence that hormones have an effect, and plays a pivotal role in determining one’s gender. This paper will discuss gender identity, the interaction of hormones and behavior and examine the biological, psychological and environmental aspects and influences on sexual differentiation. ** Hormones are the chemical messengers that produced in different glands and are in general responsible for the body to function on the proper chemical level. As needed hormones are secreted to the site of action to allow certain biological activity to take
Homeostatic Imbalance/Unit 8 Assignment William Thornbury Introduction to Anatomy and Physiology SC121 Instructor: Eric D. Steelman, DHSc(c), MPH, MS, RLATG 10/17/14 Homeostatic Imbalance The endocrine system helps regulate and maintain various body functions by synthesizing (making) and releasing hormones, chemical messengers. The major areas of control and integration include responses to stress and injury, growth and development, absorption of nutrients, energy metabolism, water and electrolyte balance, reproduction, birth, and lactation. The endocrine system is composed of glands that release their hormones directly into the bloodstream for chemical signaling of target cells. Typically, the body synthesizes hormones in one part and transports it to another through the bloodstream or lymph. Endocrine glands have a rich blood supply through which hormones travel to reach their target organs.
An example of this are the distinct sexual organs that children are born with to associate them anatomically with a gender. In addition, geneders are further differentiated when other sexual characteristic begin to display during puberty. Chemical messenger compounds known as hormones are what coordinates the appearance of such physical differences. There is research that suggests that the same sex hormones which create sexual organ differenciation in utero, and also that trigger puberty later in life may also play in important role in determining gender identity. Males normally have more of the male sex hormones called androgens than females.
adrenal medulla/adrenaline * Paracrine - that secretes hormones that affect adjacent cells e.g. gastric mucosa/gastrin/gastric pits. * Autocrine – regulate their own avtivity by the secretion of hoirmone e.g. interstitial cells of testis/testosterone Each target cell in the body is regulated only by those hormones to which it has receptor molecules , and not y others.different cells may respond in different ways to the same hormone – the transduction machinery of different target cells ‘reads’ the hormone signal in different ways. Blood hormone concentrationare usually governed by negative feedback control – a reduction in concentration stimulates additional secretion and an increase in concentration inhibits further secretion.
Hormones and the menstrual cycle The menstrual cycle is complex and controlled by many different glands and the hormones they produce. A brain structure called the hypothalamus causes the nearby pituitary gland to produce certain chemicals, which prompt the ovaries to produce the sex hormones oestrogen and progesterone. The menstrual cycle is a biofeedback system, which means each structure and gland is affected by the activity of the others. The four main phases of the menstrual cycle are menstruation, the follicular phase, ovulation and the luteal phase. Menstruation Menstruation is the elimination of the thickened lining of the uterus (endometrium) from the body through the vagina.
Hormones regulate various human functions, including metabolism, growth and development, tissue function, sleep, and mood. The field of study dealing with the endocrine system and its disorders is endocrinology, a branch of internal medicine. Features of endocrine glands are, in general, their ductless nature, their vascularity, and usually the presence of intracellular vacuoles or granules storing their hormones. In contrast, exocrine glands, such as salivary glands, sweat glands, and glands within the gastrointestinal tract, tend to
Hormones are produced by the glands and a few organs spread in different places of the body. According to Morris and Maisto (2002) the glands engaged in hormone production are thyroid, parathyroids, pineal, pituitary, gonads, and adrenal glands. Pancreas and some parts of the digestive tract also play role in the production of certain hormones which working together with glands has an effect of many other areas of the human body. Genes are which give us different hereditary characteristics. They do have an effect on behavior; but, not single genes.
Testosterone, a natural steroid, maintains sexual organs and function, triggers hair growth, and influences emotions (LeVert). Anabolic steroids can be prescribed to people with immune deficiency syndrome or males who don’t produce enough testosterone
This is seen when the clitoris on a female may look like a small penis because of the enlargement of the clitoris. CAH is caused by the exposure of androgens that are produced naturally through adrenal. Women who have a history of miscarriages use androgens to help
