The pons is a bulging section of the middle part of the brainstem, composed of transverse fibers, and is the bridge between the large and small brains, hence its name. It is located between the medulla oblongata and the midbrain, and is divided into the ventral basal and dorsal pallial regions by the medial thalamic tract. There are many important structures in the pons, including the nuclei of the adductor nucleus, the facial nucleus, the superior olivary nucleus, the pontine nucleus, and other nuclei, as well as various sensory and motor conduction tracts such as the medial longitudinal fasciculus, corticospinal tracts, and medial and lateral thalamic tracts. The pons has an important role in maintaining the functions of the human body, mainly including motor functions such as eye and limb movements, relay stations for sensory conduction, and the superior reticular activating system to maintain the conscious awareness of the human body. In the cerebral bridges, lesions such as cerebral bridge hemorrhage, cerebral bridge tumor and cerebral bridge infarction may occur, and it is important to seek medical attention in time to identify the cause of the disease and treat the symptoms.
