3. Return to the main Endocrine System homepage and click on the Pituitary Gland. a. The pituitary produces several hormones that regulate various parts including other endocrine glands. This rather large role earns it the “master gland” nickname.
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.
The peripheral nervous system, also part of the nervous system, transmits information to and from the nervous system. The biological approach also suggests chemical processes in the brain are responsible for many different psychological functioning for example, chemicals such as hormones. Imbalances of certain hormones affect behaviour. The approach states that the female hormone oestrogen gives females caring and gentle characteristics while the male hormone testosterone is linked to aggression. This hormone was investigated by Dabbs et al, where testosterone levels in prisoners where compared to the level of crime committed.
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.
Hormones and Behaviors Ronnie Gordon BEH/225 8/21/2015 George Green Hormones and Behaviors The Endocrine system is how the human body communicates feelings and emotions. Along with the endocrine system, the nervous system works to assist the lungs with breathing. Both the endocrine system and the nervous system work together to make the heart to pump as well as assist the brain in making decisions. The endocrine system works by using hormones or chemical responses to affect the physiological activity inside a person’s body. Hormones cause cells to activate and once activated, the cells must have a receptor spot for the hormone.
Our endogneous opioids control our reactions to painful stimuli and they also regulate vital functions such as hunger, thirst, mood control, immune response, and other processes. There are three kinds of receptors widely distributed throughout the brain: mu, delta, and kappa receptors. These receptors, through
Another assumption is that certain regions of the brain determine certain behaviors. The cerebral cortex has been found to affect our thinking and the prefrontal cortex is associated with mood and emotions. It has been supported by PET scans and MRI scans which have been used to objectively measure the changes in neuronal activity of the brain before and after psychosurgery. 1b) Describe Selye’s General Adaptation Syndrome (8 marks) Selye’s General Adaptation Syndrome (GAS) explains the body’s ability to cope with a particular stressor. ‘Stress’ refers to the psychological and physiological responses which occur when we perceive a threat and don’t have the resources to cope with it.
Neurological Process Paper Jennifer S. Cumella University of Phoenix Biological Foundations is Psychology PSY/340 Richard Olcese November 22, 2010 Neurological Process Paper Psychology has changed biology in many ways. The different techniques developed, which enable scientists to obtain a better understanding of the way the brain works by monitoring both the brain and the way it functions. Post translational modification, otherwise known as a modification of proteins that has proven itself to respond to different cell types during either periods of depression or elation. Some scientists say that hormones play a large role in both the activity in the mind and body. A procedure called brain mapping, which is a visual image
The SNS also regulates the sympathetic adrenal medullary system (SAM). It causes signals to travel to a gland in the kidneys called the adrenal gland which plays a vital role in the body’s response to stress. This leads to the activation of the adrenal medulla which is located in the adrenal glands. This stimulates the release of the hormone adrenaline
The thyroid also has a gland that is located at the base of the brain and controls how the thyroid works. It is called the pituitary gland and the two hormones that are produced are traveled down the bloodstream to the thyroid (Hormone). Hyperthyroidism is one of the most common diseases out of the thyroid diseases. Basically, too many of the hormone, thyroxine are produced and given to the thyroid from the pituitary gland. Hyperthyroidism speeds up the body’s metabolism which in turn makes the body have a significant weight loss, a weird heartbeat, sweating profusely, and nervousness.
