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 majority of animals on our planet, about 95 percent, do not possess a true backbone and are called invertebrates. It's common knowledge that vertebrates like humans have a complex nervous system that reacts to stimuli, but much less is known about invertebrates like shrimp and insects.he brain is a complex organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It contains billions of nerve cells that are connected by synapses to other cells and can send a train of signal pulses throughout the body.
