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

In vertebrate species it consists of two main parts, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS contains the brain and spinal cord. The PNS consists mainly of nerves, which are enclosed bundles of the long fibers or axons, that connect the CNS to every other part of the body.t the cellular level, the nervous system is defined by the presence of a special type of cell, called the neuron, also known as a nerve cell. Neurons have special structures that allow them to send signals rapidly and precisely to other cells.
