Brain

QuestionAnswer
3 Primary brain vesicles in early development are Prosencephalon, Mesencephalon, Rhombencephalon
The 5 secondary vesicles of the brain in early development Telencephalon, Diencephalon, Mesencephalon, Metencephalon, Myelencephalon
Secondary brain vesicles that forms from the Prosencephalon Telencephalon and Diencephalon= Cerebrum and Diencephalon
Secondary brain vesicles that form from the Mesencephalon Mesencephalon and Metencephalon= Midbrain
Secondary brain vesicle that forms from the Rhombencephalon Myelencephalon= Medulla
The Telencephalon becomes the what Cerebrum
The Diencephalon becomes the what Diencephalon = Thalamus, Hypothalamus and Epithalamus
The Mesencephalon becomes the what Midbrain and does not form a 2nd ventricle
The Metencephalon becomes the what Pons and Cerebellum
The Myelencephalon becomes the what Medulla
CN 1 Olfactory nerve, no motor
CN 2 Optic nerve, no motor
CN 3 Oculomotor nerve. moves eye
CN 4 Trochlear nerve, moves eye inferior and laterally
CN 5 Trigeminal nerve= 3 fold, Mastication
CN 6 Abducens nerve, moves eye laterally only
CN 7 Facial nerve, forms expressions
CN 8 Vestibulocochlear nerve, functions with the Ear
CN 9 Glossopharyngeal nerve, swallowing and gag reflex
CN 10 Vagus nerve = wandering , Head, Neck, Throat; Works together with the CN 9 in the Throat
CN 11 Accessory nerve, Neck muscles
CN 12 Hypoglossal nerve= below the tongue, movement of tongue
Cranial nerves that are in the Midbrain CN 3 and 4
Cranial nerves that are in the Pons CN 5,6,7
Cranial nerves that are in the Medulla CN 8-12 : CN 8 shared with the Pons
3 functions of the Reticular Formation Regulate muscle tone, assist in respiration, assist in Blood pressure
2 functioning systems scattered throughout the brain Reticular Formation and the Limbic System
What sensory area allows for the identifying of objects by touch with eyes closed Somatosensory Association
3 categories of functional area in the Cerebral Cortex Motor, Sensory and Association
Function and location of the Inferior Colliculi Located on the posterior side of the Midbrain of brainstem and inferior to the superior colliculi, Functions in locating direction of sound
Function and location of the Superior Colliculi Located on the posterior side of the Midbrain of brainstem and superior to the inferior colliculi, Functions in directing the eyes from stimulus
The Pontine Respiratory Group located in the Pons has 2 areas called what Pneumotaxic and Apneustic centers
Pneumotaxic and Apneustic in the Pons are responsible for what actions Generating and maintaining breathing rhythm
Cardiovascular and blood pressure are regulated from where The Medulla
Decussation of the pyramids is what The crossing of the corticospinal tract of the upper motor neurons
Longitudinal Fissure does what Divides the left and right hemispheres and is made up of Dura Mater called the Falx Cerebri
The Subdural space is where Between the Dura mater and Arachnoid mater
The sensory cortex receives information from where Thalamus
Tentorium Cerebelli is what and where Dura Mater that separates the cerebellum from the Occipital lobe
Falx Cerebri is Dura Mater that separates the left and right cerebrum
Falx Cerebelli is Dura Mater that separates the left and right cerebellum
Tentorium Cerebelli is Dura Mater that separates the occipital and temporal from the cerebellum
Function of the Thalamus Sending sensory and motor signals to the cerebral cortex, regulating sleep, consciousness and alertness
Function of Hypothalamus Eating and drinking ,bodies temperature and energy process, circadian rhythm also works with the Pituitary gland within the endocrine sys.
Basal Nuclei function is for Movement
Amygdaloid body function Fight or Flight and Emotional Memory
Putamen, Globus Pallidus and Caudate function Movement
Function of the Reticular Formation Sleep and Consciousness
Function of the Superior Olivary Complex Hearing
Pontine Respiratory center, Superior Olivary Complex and CN 5,6,7 are located where on the brainstem Pons
Association tracts are located where connect regions of the cerebral cortex within the same hemisphere
Commissural tracts are located where connect the two cerebral hemispheres; Corpus Callosum and the smaller anterior and posterior commissure
Projection tracts are where Link the cerebral cortex to inferior brain regions and the spinal cord; Corticospinal tract
Define Arcuate fibers Short Association tracts connecting neighboring gyri in the same lobe
Define Longitudinal Fasciculi Long Association tracts that connect gyri in different lobes of same hemisphere
Location and function of the Substantia Nigra Located in the Midbrain, Produces Dopamine, Black appearance due to melanin pigmentation
Location and function of the Tectum Located in the Midbrain and is responsible for auditory and visual reflexes; Contains the Superior and Inferior Colliculi
Location and function of the Tegmentum Located in the Midbrain, Contains Red Nuclei, takes information from the cerebrum and cerebellum and sends involuntary motor commands to the Erector Spinae muscle for posture while standing bending and waalking
Function of Cerebral Peduncle Connect the Brainstem to the Cerebrum at the Pons
Components of Limbic System Cingulate, Parahippocampal Gyrus, Hippocampus, Amygdaloid body, Olfactory bulbs, Fonix and other Nuclei of the Diencephalon
Function of the Limbic System are Limbic = Border ; controls emotions and memory
3 cranial Meninges Pia mater, Arachnoid mater, and Dura mater ; Pia mater in contact with brain surface
Cerebral Aqueduct connects 3rd and 4th Ventricle
CSF enters the Subarachnoid space from where Lateral and Medial Apertures
CSF recycles through what Circulates out through the Arachnoid Villi or Granulations into the dura sinuses and back into the blood system
Location of the Primary Motor Cortex Frontal Lobe on the Precentral Gyrus just anterior to the Central Sulcus
Location of the Primary Somatosensory Cortex Parietal Lobe , on the Postcentral Gyrus just posterior to the Central Sulcus
Categorical Hemisphere is the what Left Hemisphere; Language and Analytical ability
Representational Hemisphere is the what Right Hemisphere; Art and Creativity ; visual spatial
Functions of the Hypothalamus Endocrine and Autonomic nervous system
Function of the Thalamus command center for sensory signals going the the cerebrum
Function of the Epithalamus Contains the Pineal Grand ; works in the Limbic system
Wernicke area is responsible for what Recognition of the spoken and written language
Regulating Respiration is controlled from which brainstem area Pons ; the Apneustic and Pneumotaxic ceters

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

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

If you've accidentally put the card in the wrong box, just tap 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.
