Neuro for Comm

Brain & cortex and subcortex

QuestionAnswer
Gyri definition convolutions (wrinkles in brain)
Sulci/fissure definition depressions
What can happen without gyri or sulci? you may not have as much cognitive function as others
What does the cerebrum contain? 2 hemispheres where each one has a cerebral cortex and diencephalon
What is included in the diencephalon? thalamus and hypothalamus
Where is the cerebrum? outside and middle of the brain
What does the brainstem contain? mid-brain, pons, and medulla oblongata
What does the cerebellum contain? cerebellar hemispheres
What is the cerebellum called and why? the minibrain because it has 2 hemispheres
What are the primary lobes of the brain? frontal, parietal, temporal, and occipital lobes
What are 2 other lobes that aren't the primary ones? limbic lobe and insular lobe
Where is the limbic lobe found? C shape in the middle of the brain and can see in sagittal view of brain
Limbic lobe function emotions
Where is the insular lobe found? pull back the frontal and parietal bone from the temporal lobe
Insular lobe function taste center; gustation
What are 3 types of fibres in white brain matter? commissural fibres, projection fibres, and association fibres
Commissural fibres function connects the 2 brain hemispheres and is called corpus callosum
Projection fibres function convey impulses from remote regions to cerebral cortex and vise versa
Association fibres function interconnect various cortical regions in the same hemisphere
What has gray brain matter? cerebral cortex and subcortical nuclei
What is included in subcortical nuclei? basal ganglia, claustrum, and amygdaloid nucleus
What are meninges? membranes covering brain and spinal cord
What are 3 meninges? durameter, arachnoid, and piameter
What's the durameter? epidural and subdural space
What's the arachnoid? subarachnoid space where cerebrospinal fluid envelopes the brain and spinal cord
What's the piameter? closest meninge to the brain
Primary somatosensory cortex function sensation and proprioception
Primary motor cortex function motor control
Primary auditory cortex function auditory processing
Broca's area function speech and language expression
Wernicke's area function receptive language/comprehension
Angular gyrus and PTO cortex integrates sensory info for recognition/identification and is the reading center
What's the homunculus? representation of the body in the sensori-motor cortex
Allocortex in cerebrum parts olfactory bulb, hippocampus, fornix, and amygdala
Olfactory bulb function converting smells into signals
What's the olfactory bulb tract? axonal bundle from olfactory bulb to primary olfactory cortex in temporal lobe
Hippocampus function apart of limbic lobe and helps with the formation of memories
Fornix function limbic structure that helps connect hippocampus and hypothalamus & helps with visceral functions
Amygdala function visceral and vegetative functions as well as emotional responses
Subcortex in cerebrum parts basal ganglia nuclei, caudate nucleus, and lenticular nucleus
Basal ganglia function fine tuning and coordinating functions
What does evidence show the basal ganglia and thalamus to be involved in? language processing
Diencephalon in cerebrum parts thalamus, epithalamus, subthalamus, and hypothalamus
Thalamus function projection to cortex (relay to premotor, postcentral gyrus) and sensorimotor integration (receives input from cerebellum, optic tract)
Epithalamus function circadian rhythm circulation; linking olfactory system to brainstem
Subthalamus function relay of sensory information
Hypothalamus function coordination of autonomic nervous system w/endocrine pathway; participation in visual pathway

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
