called the posterior pituitary. The brain controls the activity of the pituitary gland in two ways. Releasing hormones from the hypothalamus control the secretions of the anterior pituitary and are carried in the bloodstream by hypophyseal portal veins. The posterior pituitary releases hormones into the bloodstream in response to nerve impulses from the hypothalamus. Anterior Pituitary Gland: The anterior pituitary consists mostly of epithelial tissue arranged around blood vessels

Section 1: Simply put‚ homeostasis is the maintenance of a constant internal environment in the body. (Givens and Reiss‚ 2002). To look into this definition further‚ according to Walter Cannon‚ homeostasis can be described as the way the brain coordinates body systems‚ with the aim of maintaining a set of goal values for key internal variables (Goldstein‚ 2008). Homeostasis aims to maintain a constant internal environment helping to keep internal conditions at an optimum in order for all cells in

What is Biological Psychology? It is the study of the physiological‚ evolutionary‚ and developmental mechanisms of behavior and experience. It is synonymous with the terms biopsychology‚ physiological‚ and behavioral neuroscience. Much of biological psychology is devoted to studying brain functioning. Physiology is the study of body processes- the dynamic of tissue and organ system of the body. It is the study of the physiological basis of human and animal behavior. Areas of Biological

(Taylor‚ 2012). Secondary appraisals is the initiation of the person’s response and coping strategies to the stress. Stress can take a toll on a person’s body. The cerebral cortex is responsible for labeling an event threatening or harmful. The hypothalamus gets information from the cerebral cortex to initiate the flight or fight response also known as sympathetic nervous system arousal. This arousal stimulates the medulla of the adrenal glands which then secrets epinephrine and norepinephrine (Taylor

short period of time and there is a rush of blood to the main body organs that help deliver this quick reaction which are our lungs‚ heart and major muscle that are needed to trigger a reaction. When a person encounters a dangerous situation the hypothalamus in the brain signals all adrenal glands to release adrenaline right into the blood stream. A reaction to these hormones released is given in seconds enabling a person to instantly boost physical strength and speed. This reaction also reduces the

Attachment‚ commitment‚ intimacy‚ passion‚ grief from separation‚ and jealousy are but a few of the emotionally-loaded terms used by Dianne Santorelli’s article for the educational research to describe that feeling of which love represents.

The kidneys are a pair of fist-sized organs located outside the peritoneal cavity on each side of the spine. The kidney is a highly specialized organ that maintains the internal environment of the body by selectively excreting or retaining various substances according to specific body needs.
