AP PSYCHOLOGY

Detailed explanation-1: -The brainstem is the structure that connects the cerebrum of the brain to the spinal cord and cerebellum. It is composed of three sections in descending order: the midbrain, pons, and medulla oblongata.

Detailed explanation-2: -Your cerebrum makes up about 80% of your brain. Cerebellum: Your cerebellum maintains your balance, posture, coordination and fine motor skills. It’s located in the back of your brain. Brainstem: Your brainstem regulates many automatic body functions.

Detailed explanation-3: -The named parts, from cranial to caudal, comprise the midbrain (mesencephalon), pons (metencephalon), and medulla oblongata (myelencephalon). Functions include regulation of the cardiac, respiratory, and central nervous systems including consciousness and the sleep cycle.

Detailed explanation-4: -The brainstem has many basic functions, including regulation of heart rate, breathing, sleeping, and eating. It also plays a role in conduction. All information relayed from the body to the cerebrum and cerebellum and vice versa must traverse the brainstem.
