Both penicillin and macrolide antibiotics have been regarded as acceptable therapies for group A streptococcal pharyngitis for decades. Because of its convenient dosing, azithromycin has become the most commonly used alternative to penicillin in treating this common illness. Resistance to azithromycin in the United States has remained negligible over the years.
The main function of pons is to basically act as a bridge or highway for relay of many signals to and from the cerebrum and the cerebellum. This is the center that acts as the point of origin for various nerves in the body, including the important cranial nerves.
The pons is part of the brainstem, and in humans and other bipeds lies between the midbrain (above) and the medulla oblongata (below) and in front of the cerebellum.The pons is also called the pons Varolii (bridge of Varolius), after the Italian anatomist and surgeon Costanzo Varolio (1543â75).This white matter includes tracts that conduct signals from the brain down to the cerebellum and medulla, and tracts that carry the sensory signals up into the thalamus.The pons in humans measures about 2.5 cm or 1 inch in length. Most of it appears as a broad anterior bulge rostral to the medulla.his white matter includes tracts that conduct signals from the brain down to the cerebellum and medulla, and tracts that carry the sensory signals up into the thalamus.
