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 peripheral nervous system or PNS contains the nerves, which leave the brain and the spinal cord and travel to certain areas of the body. The peripheral nervous system's main job is to send information gathered by the body's sensory receptors to the CNS as quickly as possible.he two parts are the central nervous system and the peripheral nervous. The central nervous system or the CNS contains the brain and the spinal cord. All together, the brain and the spinal cord serve the nervous system's command station.
