Document Summary
Brain: part of the cns, contained in cranial cavity. Brainstem: connects spinal cord to brain; integration of reflexes necessary for survival. Cerebellum: involved in control of locomotion, balance, posture. The brainstem is composed of the medulla oblongata, pons and midbrain. Transmits ascending and descending impulses between the brain and spinal cord. Pyramids nerve tracts conscious control of skeletal muscle. Center for vital reflexes heart rate, blood pressure, respiration, swallowing, coughing, sneezing. Olives nuclei involved in balance, coordination, modulation of sound. Nuclei of cranial nerves viii, ix, x,xi, xii. Pontine nuclei communication between cerebrum and cerebellum. Most superior portion of the brainstem nuclei of cranial nerves iii, iv. Tectum: 4 nuclei form mounds on dorsal surface of midbrain each separate part is a colliculus. Cloud throughout the brainstem controls cyclic activities such as sleep wake cycle. Cerebellum: communicates with other regions in the cns: superior cerebellar peduncle midbrain, middle cerebellar peduncle pons, inferior cerebellar peduncle medulla oblongata.
