Parts of the brain
| Question | Answer |
|---|---|
| Hindbrain | consists of the medulla, pons, and cerebellum. directs essential survival functions such as breathing ,sleeping and wakefulness as well as coordination and balance. |
| Midbrain | found atop the brainstem , connects hindbrain to forebrain. controls some motor movement and transmits auditory and visual information |
| Forebrain | consists of cerebral cortex, thalamus, hypothalamus. manages complex cognitive activities, sensory and associative functions and voluntary movements. |
| Brainstem | the central core of the brain beginning where the spinal cord swells as it enters the skull. the brainstem is responsible for automatic survival functions |
| Medulla | the hindbrain structure that is the brainstems base. controls heartbeat, breathing, chewing and silivating |
| Thalamus | The forebrains sensory control center. located atop of the brainstem and directs messages to the sensory recieving areas in the cortex and transmits replies to the cerebellum and medulla. |
| Reticular formation | a nerve network that travels through the brainstem into the thalamus. it filters information and plays a role in controlling arousal |
| Cerebellum | the hind brains "little brain" at the rear of the brainstem. its functions include processing sensory input, coordinating movement output and balance, enabiling nonverbal learning and memory. |
| Limbic System | neural system located mostly in the forebrain below cerebral hemispheres that includes amygdala, hypothalamus, and hippocampus associated with emotions and drives |
| Amygdala | two lima bean sized neural clusters in the limbic system linked to emotion |
| hypothalamus | a limbic system neural structure lying below (hypo) the thalamus. it directs several maintaneance activities (eating,drinking,body temp) helps govern the endocrine system and is linked to emotion and reward |
| Hippocampus | a neural center in limbic system that helps process explicit (concious) memories of facts and events for storage |
| Cerebral cortex | the intricate fabric of interconnected neural cells covering the forebrain’s cerebral hemispheres; the body’s ultimate control and information-processing center. |
| frontal lobes | the portion of the cerebral cortex lying behind the forehead. it is involved in speaking speaking and muscle movements and in making plans and judgements |
| Parietal lobes | the portion of the cerebral cortex lying at the top of the head and toward the rear. it receives sensory input for touch and body position |
| Occipital lobes | the portion of the cerebral cortex lying at the back of the head. includes areas that revieve information from the visual fields |
| Temporal lobes | the portion of the cerebral cortex lying roughly above the ears. it includes auditory areas each of which revieves information primarily from opposite ear. |
| Motor cortex | a cerebral cortex area at the rear of the frontal lobes that controls voluntary movements |
| Somatosensory cortex | a cerebral cortex area at the front of the parietal lobes that registers and processes body touch and movement sensations |
| Association areas | areas of the cerebral cortex that are not involved in primary motor or sensory functions but rather are involved in higher mental functions such as learning, remembering, speaking and thinking. |
