Study Notes
- The brain is composed of three main parts: the cerebrum, cerebellum, and medulla oblongata. The cerebrum governs intelligence, reasoning, learning, and memory, while the cerebellum coordinates muscle coordination and balance.
- The cerebral hemispheres are part of the conscious brain and are responsible for higher forms of thinking. They are connected by the corpus callosum, which allows communication between the two hemispheres.
- The hypothalamus, located in the forebrain, regulates homeostasis by controlling thirst, hunger, body temperature, water balance, and blood pressure. It also links the nervous system to the endocrine system.
- The thalamus acts as a central relay point for incoming nervous messages and directs sensory messages to higher brain centers. The sense of smell bypasses the thalamus and goes directly to the olfactory bulb.
- The limbic system includes the amygdala, responsible for evaluating sensory information and determining emotional importance, and the hippocampus, which is the gateway to memory.
