| skin physiology | The functions of the skin in the human and animal body. It includes the pigmentation of the skin and its appendages. (12 Dec 1998) |
| nervous system physiology | Functions and activities of the nervous system as a whole or with reference to the peripheral or the central nervous system. (12 Dec 1998) |

| up-regulation (physiology) | Process that increases ligand/receptor interactions due to an increase in the number of available receptors. (12 Dec 1998) |
| urinary tract physiology | Functions and activities of the urinary tract as a whole or of any of its parts. (12 Dec 1998) |
| acute respiratory failure | Loss of pulmonary function either acute or chronic that results in hypoxaemia or hypercarbia. (05 Mar 2000) |
| adult respiratory distress syndrome | <chest medicine, syndrome> A clinical syndrome that includes pulmonary insufficiency. It is a descriptive term that is applied to a variety of diffuse infiltrative processes in the lung. Manifestations include severe shortness of breath, rapid breathing and arterial hypoxaemia (low oxygen). Chest X-ray shows bilateral diffuse infiltrates. Treatment most often includes mechanical respiratory support. Causes include toxic gas (chlorine, NO2, smoke) exposure, severe metabolic derangement, gastric acid aspiration, pancreatitis, sepsis and trauma. Acronym: ARDS (12 Jul 2000) |
| alkalosis, respiratory | A state due to excess loss of carbon dioxide from the body. (12 Dec 1998) |
| Bell's respiratory nerve | <anatomy, nerve> Arises from the fifth, sixth, and seventh cervical nerves (roots of brachial plexus), descends the neck behind the brachial plexus, and is distributed to the serratus anterior muscle; it is somewhat unusual in that it courses on the superficial aspect of the muscle is supplies; its paralysis results in "winged scapula". Synonym: nervus thoracicus longus, Bell's respiratory nerve, external respiratory nerve of Bell, posterior thoracic nerve. (05 Mar 2000) |
| bovine respiratory syncytial virus | A pneumovirus causing an emerging disease in young cattle characterised by pneumonia, interstitial pulmonary oedema, and emphysema; sheep are also susceptible to the virus. (05 Mar 2000) |
| rate, respiratory | The number of breaths per minute (or, more formally, the number of movements indicative of inspiration and expiration per unit time). In practice, the respiratory rate is usually determined by counting the number of times the chest rises (or falls) per minute. By whatever means, the aim is to determine if the respirations are normal, abnormally fast (tachypnea), abnormally slow (technically termed bradypnea), or nonexistent (apnea). (12 Dec 1998) |
| Gierke's respiratory bundle | A slender, compact fibre bundle extending longitudinally through the dorsolateral region of the medullary tegmentum, surrounded by the nucleus of the solitary tract, below the obex decussating over the central canal, and descending over some distance into the upper cervical segments of the spinal cord. It is composed of primary sensory fibres that enter with the vagus, glossopharyngeal, and facial nerves, and in part convey information from stretch receptors and chemoreceptors in the walls of the cardiovascular, respiratory, and intestinal tracts; in rostral parts of the tract impulses are generated by the receptor cells of the taste buds in the mucosa of the tongue. Its fibres are distributed to the nucleus of the solitary tract. Synonym: tractus solitarius, fasciculus rotundus, fasciculus solitarius, funiculus solitarius, Gierke's respiratory bundle, Krause's respiratory bundle, round fasciculus, solitary bundle, solitary fasciculus.
