Brain Functions and Anatomy

The video tutorial covers Unit 3, Lesson 9 on the nervous system, focusing on the brain. It introduces key vocabulary related to brain anatomy and functions, such as the brain stem, cerebrum, and cerebellum. The lesson explains the roles of the spinal cord and brain in the nervous system, highlighting how the brain processes sensory information and controls muscle function. It also discusses the brain's protection mechanisms and the impact of injuries like concussions. The tutorial further explores the brain's structure, including the medulla, cerebellum, and cerebrum, and their respective functions. Finally, it touches on recent advancements in brain research using PET scans to understand brain activity and the distinct functions of the left and right hemispheres.
