Uterine contraction. Drugs that bind to Beta 2 receptors (Beta 2 agonists) are used in the treatment of premature labour, this clinical application illustrates how Beta 2 receptors mediate tocolysis on the uterine muscle. Ritodrine is an example of a tocolytic drug.y Flavio Guzman, GuzmÃ¡n.M. D beta receptors are a subtype of adrenergic (receptor), adrenoceptor their activation triggers a (sympathomimetic) adrenergic. Response this article overviews the characteristics related to their physiology and pharmacological. Aspects in, addition a related article discusses alpha. receptors

The Central Nervous System This page outlines the basic physiology of the central nervous system, including the brain and spinal cord. Separate pages describe the nervous system in general, sensation, control of skeletal muscle and control of internal organs. The central nervous system CNS is responsible for integrating sensory information and responding accordingly. It consists of two main components: The spinal cord serves as a conduit for signals between the brain and the rest of the body. It also controls simple musculoskeletal reflexes without input from the brain.
