division of the brainstem that connects the medulla with the cerebellum?
medulla oblongata
the pons lies between the medulla oblongata and the midbrain. it contains tracts that carry signals from the cerebrum to the medulla and to the cerebellum and also tracts that carry sensory signals to the thalamus. the pons is connected to the cerebellum by the cerebellar peduncles. the pons houses the respiratory pneumotaxic center and apneustic center that make up the pontine respiratory group in the respiratory center. the pons co-ordinates activities of the cerebellar hemispheres.









































the pons and medulla oblongata are parts of the hindbrain that form much of the brainstem.

brainstem
depending on the location of the brain lesion different symptoms are more frequent:









































bullet::::- brainstem tegmentum. - ocular: pupillary changes. extraocular muscle palsy; gaze palsy: nystagmus.









































bullet::::- hypothalamus. medulla: dorsal nuc. of vagus. - autonomic dysfunct.: temperature; cardiocirculatory; respiratory.









































bullet::::- medulla: vestibular region. cerebellum. - ataxia.









































bullet::::- dorsomedial nuc. of thalamus. mammillary bodies. - amnestic syndrome for recent memory.









































mamillary lesion are characteristic-small petechial hemorrhages are found.









































bullet::::- diffuse cerebral dysfunction.- altered cognition: global confusional state.









































bullet::::- brainstem: periaqueductal gray.- reduction of consciousness
