This is called acute adrenal failure or an Addisonian crisis. It can be fatal if it isn't cared for. The indications may include: Pain in the abdomen, lower back or legs Severe vomiting and diarrhea Dehydration Low blood pressure Loss of consciousness (Addison's disease, 2010). Secondary adrenal deficiency takes place when the pituitary gland fails to manufacture adequate adrenocorticotropin (ACTH), a hormone that rouses the adrenal glands to produce cortisol. If ACTH production is too

Nervous System: In order to achieve its function, the nervous system is divided into two major parts i.e. The Central Nervous System (CNS) and Peripheral Nervous System (PNS). The central nervous system is basically made up of the brain and spinal cord and has the main function of receiving information from the body and sending out instructions. While the brain is protected by the skull, the spinal cord is guarded

Toxins are poisonous substances that can cause harm to human beings via one or more of its physiological systems. For example, DDT is a toxin used to kill insects but which also affects the human endocrine system. Tetrodotoxin is a toxin found in the venom of animals like frogs and pufferfish, but if it enters the human nervous system can cause paralysis or death. Mercury is a naturally-occurring element like

Endocrine control of BP Hormonal Control of Osmotic pressure: Stimulation Arterial blood pressure (BP) is under tight control by the mammalian nervous system, cardiovascular system, kidneys, and endocrine system (Vivas et al., 2014). The VII, IX, and X cranial nerves conduct peripheral taste, osmo-sodium, volume, and baroreceptor information to the solitary tract, while the distinct bundles of neurons in the lamina terminalis respond to changes in plasma and cerebral spinal fluid sodium

E. hypertrophy). In the elderly, this process is reverse. Hence, the functional reserve capacities of the skeletal muscles decline with age, largely due to diminished levels of physical activity. As a result daily tasks once taken for granted become progressively more difficult, and eventually impossible, to perform. In illustration, a great deal of muscle force is required to simply stand up or to climb stairs. Therefore, skeletal system is relying

Nervous System The major structures of basal ganglia are pallidum, substantia nigra, subthalamic nucleus, and striatum. They are inappropriately named because the name striatum refers to all major components of basal ganglia. However it was used to refer to only one of the structures. The general function of basal ganglia is to take part in learning and motor control. Is called motor cortex, receives its primary input from the ganglia structures The
