Brain Part 1
Brain Part 2
| Question | Answer |
|---|---|
| The thalamus, hypothalamus and the epithalamus make up the | diencephalon |
| part of the diencephalon that receive sensory info, integrates it and sends it to the cerebral cortex | thalamus |
| part of the diencephalon that has a major role in cognition, emotion and memories | thalamus |
| Which part of the diencephalon is a major regulator of homeostasis | hypothalamus |
| Extending from the epithalamus is the ___________ glands | pineal gland |
| this part of the diencephalon is part of the endocrine system and secrete melatonic to regulate the biological clock | epithalamus/pineal gland |
| part of the brain that is the "seat of intelligence" - all conscious acs and higher thought occurs here | cerebrum |
| is the external cerebral cortex made of white or gray matter | gray matter |
| is the internal cerebral cortex made of white or gray matter | white matter |
| what is gray matter nuclei | speckles of gray matter throughout the white matter |
| which is the primary motor area of the cerebrum: precentral gyrus or postcentral gyrus | precentral gyrus |
| which is the primary somatosensory area of the cerebrum: precentral gyrus or postcentral gyrus | postcentral gyrus |
| fibers in the cerebrum that have nerve impulses within gyri in the same hemisphere | association fibers |
| fibers in the cerebrum that correspond to gyrus in the opposite hemisphere | commissural fibers |
| fibers in the cerebrum that are ascending or descending tracts between brain and spinal cord | projection fibers |
| where are basal ganglia found | in masses of gray matter depp within each hemisphere |
| what do basal ganglia do | begin/end movement, attention, memeory, planning, limbic system |
| What do the association areas of teh cerebral cortex do? | put meaning to sensory input...integrate functions |
| What are primary sensory areas responsible for? | only receive input such as shape, color, pitch, taste - DO NOT give meaning or names to the input |
| What are secondary sensory areas responsible for? | giving meaning and recognition to the input received from sensory receptors |
| What lobe has the primary visual sensory area? | occipital lobe |
| What lobe has the auditory primary sensory area? | temporal lobe |
| What lobe has the olfactory primary sensory area? | temporal lobe |
| Where are the primary motor areas found? | precentral gyrus |
| What is Wernicke's area responsible for? | interpretation of words and tone of voice |
| Which part of the brain is reponsible for personality, reasoning and judgement? | prefrontal cortex |
| What part of the brain is responsible for learned motor skills? | premotor cortex |
| brain wave that occurs when awake & resting with eyes closed | alpha |
| brain wave that occurs when eyes are open and performing mental tasks and taking in sensory input | beta |
| type of brain wave that occurs during emotional stress | theta |
| type of brain wave that occurs during deep sleep | delta |
| How many stages of non-REM sleep and how long does it take to complete them? | 4 - takes about 30-45 minutes |
| Stage 1 of non-REM sleep | drifing sensation |
| Stage 2 of non-REM sleep | light sleep - still easily aroused |
| Stage 3 of non-REM sleep | vital signs change |
| Stage 4 of non-REM sleep | deep sleep |
| About how many times does REM sleep occur in a night | about 5 |
