PSY 430 Lecture Notes - Lecture 6: Substantia Nigra, Reticular Formation, Cranial Nerves
Document Summary
D: located at the posterior portion of the brain, help make up the brain stem, consists of the: I: comprises the lower portion of the brain stem with the medulla, pons, and cerebellum. E: controls a lot of involuntary regulations like heart rate as well as re exes. D: located just above the spinal cord - responsible for vital re exes like breathing, heart rate, vomiting, salivation, coughing and sneezing. Cranial nerves allow the medulla to control sensations from the head, muscle movements in the head, and many parasympathetic outputs to organs. I: structure within the hindbrain that is responsible for re ects and regulatory responses like breathing, heart rate, and salivation. E: cranial nerves aid with the medulla for sensation control and muscle movements. D: lies on each side of the medulla (ventral and anterior) - contains reticular formation and raphe system; works to increase arousal and readiness of other parts of the brain.
