This area is responsible for higher mental functions.Notice that there are visible folds ("bumps and grooves") on this structure. Each elevated bump is called a 2 while each shallow groove is called a3Located at the "back of the brain" is the 4coordinates equilibrium and motor activity to produce smooth, controlled movements.In the longitudinal cut you are looking at, you'll notice that it has an internal, tree-like pattern called arbor vitae. This part of the brainThe brain stem connects the brain to the spinal cord. It kind of looks like a tail coming out the back. It includes three parts including the posterior-most _5 , the bulb-like 6most 7 This region of the brain contains centers for breathing and heart rate. It also serves as a relay station for nerve impulses traveling between the brain and the spinal cord.and anterior-As our narrator moves forward/anterior we can see some of the deep structures of the brain.An area called the diencephalon includes the thalamus, which serves as an integrating center for sensory input. Immediately below it, is the 8 which is critically important for helping usmaintain homeostasis. The pituitary gland, which is sometimes referred to as the "master gland" of the endocrine system attaches to this structure by a stalk-like connection, but it is not visiblein the specimen we're looking at.Nearby, is the9which releases the hormone melatonin and, consequently, helps regulate sleep/wake cycles.10"bottom lip" is the fornix and the visible space between these 2 structures is called the 11reservoir for cerebral spinal fluid.is a conspicuous fibrous tract (the narrator describes it as a "top lip") deep within the brain that enables communication between the two cerebral hemispheres. Below it, theThe brain has four ventricles, interconnecting chambers that produce and serve as aAnother ventricle is found in the crevice between the cerebellum and the brain stem.A few cranial nerves are visible when looking on the underside of the brain.
