Document Summary

Characteristics of typical brain: weight = 3lbs, volume = 1. 2l. Neural tube is derived from the ectoderm. Prosencephalon: splits into diencephalon (thalamus) and telencephalon (cerebrum) Mesencephalon: midbrain still rhombencephalon: metencephalon (develops into cerebellum, pons), myelencephalon. Brain development (develops into medulla oblongata continuous with the spinal cord) increasing complexity the further you get toward the cranial end. A lateral view of the brain of an embryo after. 4 weeks of development showing the neural tube. A lateral view of the brain of a 5-week-old embryo. Brain development in a child, showing the cerebrum covering other portions of the brain. Brainstem versa: medulla, pons, midbrain, pons bridge; a relay station that projects information from medulla to rest of brain and vice thalamus. Also connection between brainstem and the cerebellum. Connects cerebellum with rest of the brain: midbrain deals with auditory and visual input. Any reflexes associated with these sensory functions is controlled by the midbrain.
