Document Summary
Pons (messages between the cerebellum ad cortex; sleep, dreaming) Midbrain- segment of brainstem that lies between the hindbrain and the forebrain. Integrates sensory processes such as vision and hearing o. Cerebellum- controls and coordinates all involuntary, rapid, fine motor movement as well as voluntary movements that happen in rapid succession o. Cant fully extend arm out or touch nose properly (ex: of damage to cerebellum) H-omeostasis ( keeps things functioning in normal range [temp]) Hypothalamus is really involved with controlling the endocrine system. Thalamus- round structure in center of brain that works as the sensory switch board , relaying incoming sensory info to appropriate areas except smel. Thirst, hunger, body temp, sleeping & waking, sexual behavior) o. Plays vital role in learning and memory (for facts/knowledge) Amygdala- 2 almond shaped neural clusters linked to/with emotion, esp. fear. Cortex-covering of brain consisting of densely packed neurons, responsible for higher thought processes and interpretation of sensory output o o.
