With regard to the anterior pituitary, neurons in the hypothalamus secrete a group of compounds called releasing hormones that are absorbed into the primary capillaries. These compounds in turn effect the secretion of stimulating hormones into the secondary capillaries to take them all over the body by the blood. Some of these from the anterior pituitary are called tropic hormones because they stimulate specific endocrine glands. The two targeting the reproductive organs are called gonadotropins. Secretion of most tropic hormones is achieved by negative feedback of the target gland hormones acting on the hypothalamus. The non-tropic hormone from the anterior pituitary is…
The male sex hormone testosterone is produced in the male testes and in the adrenal cortex. It is thought to increase levels of aggression from young adulthood onwards. It is thought that testosterone may influence areas of the brain that control behavioural reactions, such as the amygdala and the hypothalamus. Testosterone influences the levels of other hormones which are…
Through adolescence, hormone levels correlate with physiological changes and self-reported development. Hormones are body chemicals that can regulate hunger, sleep, moods, stress, sexual desire, immunity, reproduction, and many other bodily reactions, including puberty. The pituitary produces hormones that stimulate the adrenal glands, located above the kidneys, which produce more hormones. Another hormonal sequence is called HPG axis.…
3. Example…. There is a Female hormone called Follicle Stimulating Hormone (FSH) which tells the ovaries to do one thing only and that is to produce a group of hormones called estrogens.…
Gender refers to the social, psychology and behavioural aspects of being male or female. In other words, masculinity or femininity, however this is different from Sex, which is the biological fact of being male or female. This is normally identified by chromosomes and genitalia. The hundred of genes we have in our 23 pairs of chromosomes carry information about our physical and behavioural characteristics. The sex chromosomes are thought to determine biological sex. There is usually a direct link between chromosomal sex and external genitalia and the internal genitalia.…
After conception, it is not until the embryo reaches 6 weeks old that gonads begin to develop differently. If the embryo is to be a male, the gene on the Y chromosome triggers the events that transform the male embryo gonads into testes. However if the embryo is to be female, the absence of the Y chromosome, will cause the gonads to automatically develop into ovaries. Once the testes and ovaries have developed they begin to release their own sex hormones; male hormones are known as androgens; female hormones are known as oestrogens.…
From fetus our genitals are the same. Our genitals form within the first six weeks. XX or XY chromosomes are the contributing factors to the differences in the development of our genitals. As we grow the male and female body begins to produce hormones. These hormones are testosterone and estrogen. Males produce more testosterone and females produce more estrogen. Our bodies produce these hormones and many others. Hormones affect how the body reacts. These reactions reveal the similarities and differences between males and females. This exchange process produces the differences between our biological chemistry (Spencer, 1999).…
My literature review focus on the possible causes that contribute to the higher index of Alzheimer’s disease in women compared to men such as women life expectancy and menopause, and presents through studies, different types of prevention methods such as hormone replacement therapy (HTR), multivitamin, neuroprotectin supplementation.…
Touch receptors called Meissner’s corpuscles are found in the papillary region of the dermis of the skin. When nothing is touching the skin, a voltage difference known as the (1) ___________ _____________ _____________ exists across the plasma membrane. Leakage channels, also called passive channels, allow the movement of potassium (and sodium) across the membrane. Due to the electrochemical gradient, (2) ___________________ (ion) diffuses out of the cell. Because of this and because proteins that are large, non-diffusible anions are more abundant in the cell than outside it, the fluid on the inside adjacent to the plasma membrane is – (3) negatively / positively (circle or highlight one) – charged compared to the fluid on the outside immediately adjacent to the plasma membrane. The (4) _______________________ actively moves sodium and potassium ions against their electrochemical gradients using (5)______ (energy source), thus it moves (6) __________________ (ion) out of the cell and (7)_________________ into the cell to maintain the ions’ electrochemical gradients.…
