Refimprove date December 2009 In physiology , transduction is the conversion of a stimulus from one form to another. Transduction in the nervous system typically refers to stimulus alerting events wherein a mechanical physical etc stimulus is converted into an action potential which is transmitted along axons towards the central nervous system where it is integrated. For example, in the visual system , sensory cells called Rod cell rod and cone cell s in the retina convert the physical energy of light signals into electrical impulse s that travel to the brain . The light causes a conformational change in a protein called rhodopsin . This conformational change sets in motion a series of molecular events that result in a reduction of the electrochemical gradient of the photoreceptor. The decrease in the electrochemical gradient causes a reduction in the electrical signals going to the brain. Thus, in this example, more light hitting the photoreceptor results in the transduction of a signal into fewer electrical impulses, effectively communicating that stimulus to the brain. A change in neurotransmitter release is mediated through a second messenger system. Note that the change in neurotransmitter release is by rods. Because of the change, a change in light intensity causes the response of the rods to be much slower than expected for a process associated with the nervous system . ref Silverthorn, Dee Unglaub.

Cell physiology including cellular electrophysiology is the biological study of the cell biology cell s mechanism and interaction in its environment. The term physiology refers to all the normal functions that take place in a living organism. Absorption of water by roots, production of food in the leaves, and growth of shoots towards light are examples of plant physiology. The heterotrophic metabolism of food derived from plants and animals and the use of movement to obtain nutrients even if the organism itself remains in a relatively stationary position are characteristic of animal physiology. In the context of human physiology , cell physiology is often the term used to describe the physiology of cell membrane membrane transport, neuron transmission, and less frequently muscle contraction. In general these cover the digestion of food, circulation of blood and contraction of muscles and, therefore, are important aspects of human physiology. For a more complete description of the general physiological function of human cells as well as the cells of other life forms , see the article on cell biology General characteristics of cell physiology There are two types of cells, Prokaryote s and Eukaryote s. Prokaryotes first came into existence and contain no self contained nucleus, therefore making their mechanisms much simpler compared to the later evolved Eukaryotes , which do contain a cell nucleus nucleus enveloping the cell s DNA and nuclear organelles . Because virus es, viroid s, prion s and such see Acytota Aphanobionta depend entirely on the physiology of other cells i.e., cells containing their own physiology , the former entities are often not considered to be living by the biologists who study them.

Hallerian physiology was a theory competing with galvanism in Italy in the late 18th century. It is named after Albrecht von Haller , a Switzerland Swiss physician who is considered the father of neurology . The hallerians fundamental tenet held that muscular movements were produced by a mechanics mechanical force force, different from life and from the nervous system , and which operated beyond consciousness . The activity of this function could be controlled in dead and dissected animals by touching a metal knife to the muscle fiber or by a spark being discharged on them. The electricity operated only as a stimulus of irritability , and it was irritability which was the one, true cause of the contractions.

In physiology , respiration often confused with breathing is defined as the transport of oxygen from the outside air to the cells within Tissue biology tissue s, and the transport of carbon dioxide in the opposite direction. This is in contrast to the Biochemistry biochemical definition of respiration, which refers to cellular respiration the metabolism metabolic process by which an organism obtains energy by reacting oxygen with glucose to give water , carbon dioxide and Adenosine triphosphate ATP energy . Although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct cellular respiration takes place in individual cells of the organism, while physiologic respiration concerns the bulk flow and transport of metabolites between the organism and the external environment. In unicellular organisms, simple diffusion is sufficient for gas exchange every cell is constantly bathed in the external environment, with only a short distance for gases to flow across. In contrast, complex multicellular animals such as humans have a much greater distance between the environment and their innermost cells, thus, a respiratory system is needed for effective gas exchange.
