The Human Growth Hormone and Its Effects on Our Bodies as We Age In this paper‚ I will explain what the human growth hormone is; its effects on our bodies as we age. Also‚ show the benefits received by following a prescribed treatment plant from a qualified physician. The results are amazing‚ as you will see; this has prompted more research into the benefits of hormone replacement therapy as we age.

Discuss the role of genes and hormones in gender development (24 marks) 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

A hormone is a biochemical produced by the glands of the endocrine system which is transported by the bloodstream to specific cells and organs around the body in order to initiate specific biological responses. The human body can produce a large number of hormones‚ many of which have a large influence on our emotions and behavior. Common examples are adrenaline‚ oxytocin‚ oestrogen‚ and testosterone‚ which I will be using to demonstrate the vast influence which hormones have over our everyday lives

Gender development can be explained by biological influences which includes hormones and genes. The base line of biological influences in gender development is that biological sex is determined by sex chromosomes‚ XX for female and XY for males. But this approach also argues that genes and hormones are the main influence on gender roles and gender identity in gender development. A research by Ridley has found out that biological sex is determined by a single gene called SRY gene and argued that

melatonin stimulation of growth hormone release via somatostatin inhibition Joseph Angelo Israel Peguit University of the Philippines in the Visayas Cebu College Natural Sciences and Mathematics Division Abstract Secretion of growth hormone is affected by two primary hormones: Growth hormone-releasing hormone and somatostatin. The former is the primary stimulant to promote growth hormone secretion while the latter is the primary inhibitor that prevents growth hormone secretion. Many studies

The potential sexual differentiation in the Gonadotropin-Releasing Hormone Neuron Count in the Rostral Preoptic Area of a Mouse. Abstract It is known that the HPG axis is sexually differentiated in GnRH neuron populations. In mice this is seen to be sexually differentiated in the secretary patterns of the synaptic projections instead of the cell count itself. This experiment proves that it is not the cell count of GnRH neurons that is sexually differentiated by conducting a single label immunohistochemistry

changes via the excretion of specific chemicals known as hormones. The endocrine system is one of the body’s two major communication systems‚ the nervous system being the other. Communication within the nervous system is rapid‚ while the signals sent by the endocrine system may have much longer delays and last for much greater lengths of time. The endocrine system consists of all those glands termed endocrine glands‚ which secrete hormones. Hormones are chemical messengers that enter the blood‚ which
