| Question | Answer |
|---|---|
| Define Grey Matter | Neuronal Cell bodies (outer layer of brain) |
| Define White Matter | Myelinated axons (inner part of the brain) |
| Define Corpus Callosum | Myelinated connector of the brain hemispheres |
| Name the 3 structures of the brain | Forebrain Midbrain Hindbrain |
| Define Forebrain | Surrounds mid and hind Contains all 4 lobes |
| Define Midbrain | transfers auditory info to forebrain conducts eye movement Contains motor and sensory information source for NT |
| Define Hindbrain | Contains physiological functions on top of the spinal cord cerebellum is the largest region |
| T or F, front of the brain is called anterior | T |
| T or F, Back of the brain is called posterior | T |
| T or F, Inferior means dorsal | F |
| T or F, superior means ventral | F |
| Define Cerebral Cortex | Outer layer of forebrain 3mm thick 80% of the brain 300 in^2 or 2000 cm^2 4 lobes sensory motor association |
| what happens in association areas? | Cognitive functions Analyzes data from senses represent non physical things through showing |
| what happens in Motor Areas | Control muscle movement Signals leave from brain to destination more movement= more brain power |
| what happens in Sensory Areas | control senses Destination of signals Somatosensory= from skin Sensitive body parts have sensitive regions |
| Contralateral | One side of the brain controls the other side |
| Subcortical structures | Thalamus Hypthalamus Limbic System |
| What is the Limbic system made of | Amygdala and Hippocampus |
| Role of Thalamus | Messanger for processing |
| Role of hippocampus | learning and memory |
| role of amygdala | emotional processing |
| role of hypothalamus | behavior for physiological needs |
| C, F, T, M, H, A, H | Colorful Fruits Taste Maginificent Healthy Always Happy |
| Brain Lateralization | Brain is connected by fiber bundles/ commissures Right Brain= Vision and Audio Left Brain= Communcation |
| Split brain patients have | limited communication last call for epilepsy |
