Which parts of the brain makes up the brainstem? | 1. midbrain 2. pons 3. medulla |
Which 3 functions does the brainstem conduct? | 1. receives sensory input from cranial structures and controls muscles of the head 2. serves as a conduit of information flow (ascending and descending tracts) 3. integrates information from other sources |
Key function of medulla | Blood pressure, respiration regulation |
Key function of pons and midbrain | eye movement |
Principal functions of the cerebellum: | 1. regulate eye and limb movement 2. posture and balance 3. some contribution to language, cognition, emotion |
The diencephalon consists of _______ and ______. | Thalamus and hypothalamus |
The hypothalamus controls _________ release in the ______ gland and overall function of the _________ system. | The hypothalamus controls [endocrine hormone] release in the [pituitary] gland and overall function of the [autonomic nervous] system. |
