Fear affects everyone in some way, and some much more cripplingly then others. Fear has…

Introduction The cardiovascular system provides appropriate organ and tissue perfusion at rest and at times of stress by regulation of blood pressure (BP). BP can be expressed as the product of cardiac output (CO) and peripheral resistance. The arterial pressure level at any given time reflects the composite activities of the heart and the peripheral circulation.(Jones, 2004). Nervous system, hormonal and Kidney factors control blood pressure. 1. Nervous System 1.1 CO – Cardiac output CO…

but it is under control by the thermoregulatory center which can be found in the hypothalamus (Rizzo the part of the brain that controls secretion from the pituitary gland (2006 p. 485)) which apprehend information from two fixed thermoregulation receptors (needed for the body to make its appropriate adjustment). The main purpose of these receptors is to find out someone’s temperature of their blood, which it travels…

A degenerative or idiopathic disease is characterized by the deterioration and loss of functions of internal organs and cells. An example of this disease would be Laminitis, which is a painful, and potentially crippling disease that can be fatal to horses. A horse may have to be humanely euthanized if the effects of the disease have become so serious that it is inhumane to continue to attempt further treatment. Laminitis can affect any of the feet but is more commonly seen in the front feet. Any…

division enables an organism to respond to its environment by stimulating activities of glands and muscle contraction. The motor division includes the autonomic system and the somatic nervous system. The somatic system is in charge of skeletal muscle contraction, which is normally voluntary. Whereas the autonomic nervous system is responsible for involuntary responses. For example, changes in the activities of glands or the digestive system. These systems often work together, like when you’re…

trigger mood changes making the life of the stressed victim, leading to lack of appetite resulting in the body not having energy and the performance of the key organs in the body such as immune system performance going down and damage to the pituitary gland hence causing exhaustion to the body (Kramer, 2005).

The brain is the most complex part of the human body. It is also the most powerful organ of the human body, although it only weighs approximately three pounds (Alzheimer’s Association, 2012). The brain is responsible for all thought and movement that your body produces. The complexity of the brain allows humans to interact with their environment and communicate successfully with others. The brain is not just one huge organ, it has numerous small divisions that enable humans to thrive and survive…

Fear is most commonly recognized as a simple feeling we get when faced with a potentially dangerous situation. However, it is a complex response from the brain in order to protect ourselves from a threatening situation. Fear is not as simple as it may seem, and there are many aspects to it that are overlooked including the process and effects, as well as many other things. There are five parts of the brain involved with fear and the response to it. The thalamus receives incoming data and decides…
