dangerous if someone with a heart attack have pain in their arm‚ and they might not recognize what is happening to them. 2. Why olfaction and gustation are considered “chemical” special senses? Both olfaction and gustation are chemosensory systems. Chemoreception means a molecule from the environment binds to a receptor on a cell’s surface. The receptor is shaped to receive and then respond when a specific type of molecule binds. This binding triggers a signal with the information about

Biological psychology hypothesises that the nervous system has the ability to influence the way we see the world around us. So much hinges on the existence of these cells that even different schools can agree upon their existence. A nerve cell‚ also known as a neuron‚ is defined as “Any of the impulse

A Better Understanding: Neurochemistry of Addiction To better understand the fundamentals of neurochemistry‚ a good start is at the brain. The brain makes up the central nervous system and is connected to the whole nervous system that runs through the whole body. The central nervous system receives sensory information and controls the body’s response. For example‚ a pot on a stove would be extremely hot on the hands when the stove is on and would damage the skin. This sensory information is sent

Ivan Pavlov A Man and His Dogs Many students who eat a hearty breakfast and do not feel hungry as lunchtime rolls around find themselves rushing to the lunchroom with a ravenous appetite as soon as the bell rings. A typical conditioned response‚ just as Pavlov’s famous dogs did many years ago. Nobel Prize winning physiologist‚ Ivan Pavlov‚ first identified this psychological/physiological phenomenon in the late nineteenth century. Since then‚ the term “Pavlovian Response” has become synonymous

Most organism are active in a limited temperature range The role of Enzymes in metabolism‚ their chemical composition and specificity on substrates Role of enzymes * Enzymes are organic catalysts. They are protein molecules that increase the rate of the reactions in living organisms. * Without enzymes‚ metabolic reactions at body temperatures would be too slow to produce sufficient energy to maintain life * Intracellular enzymes are used in the cells

which are needed to live. Some of those elements are calcium‚ phosphorus‚ potassium‚ sulfur‚ sodium‚ magnesium‚ and many more. In the circulatory system‚ two elements that are critical to the circulatory system are iron and oxygen‚ without these two elements it would be impossible for the system to function. The circulatory system is an organ system that permits blood and lymph circulation to transport nutrients (such as amino acids and electrolytes)‚ oxygen‚ carbon dioxide‚ hormones‚ blood cells
