MAX Returns MANDy's OVum... what is this Mnemonic used to help remember? | MAXillary nerve - foramen Rotundum, MANDibulur Nerve - foramen OVale. /// the Trigeminal N CN V has 3 branches and this helps you remember where 2 of them exit the skull. |
What are the embryonic development of the divisions of the brain. Hint there are 5 of them? | Toddler's MESsy DIapers Turn Yellow.// Telencephalon, MESencephalon, DIencephalon, meTencephalon, mYencephalon |
What Dura mater is made up of what two layer? | Periosteal and Meningeal Layer |
What the layers that cover the brain (start superficial and work deep) also in what layer do the blood vessel sit? | Dura Mater, Arachnoid mater, Pia mater. /// Blood vessel sit b/t Arachnoid and Pia mater in the Subarachnoid space. |
What are the 4 ventricles of the brain and where are they located? | 1. Two Lateral Ventricles - each hemisphere of cerebrum. // 2. Third Ventricle - Diencephalon // 3. Fourth Ventricle - b/t Pons and Cerebellum |
Name 3 functions of the CSF. | 1. Buoyancy - brain floats in CSF // 2. Protection - Liquid cushion from sudden movements // 3. Environmental Stability - Transport nutrients and removes waste. |
Why are the Ependymal cells of the Choroid Plexus important? | Formation of Cerebral Spinal Fluid |
The venous fluid of the Superior sagittal sinus (dural venous sinus)and arachnoid villus are located b/t what two layers? | The Periosteal and Meningeal layer of the Dura Mater. |
Tell me where the CSF is produced and how it travels around the CNS until it is dumped back into the venous system. | Ependymal cells of the Choroid Plexus mostly in the Lateral ventricles >from third Ventricle> cerebral aqueduct> into fourth Ventricle> subarachnoid space> central canal spinal cord> Arachnoid villus> Sup Sagittal sinus/dural venous sinus |
In the brain where is the Blood Brain Barrier (Astrocyte Perivascular Feet contribute) missing or reduced? | Choroid Plexus /// Hypothalamus /// Pineal Gland |
Wernicke's Area is located in what lobe of your cerebral cortex? | Parietal and Temporal - your Parents (parietal) taught you to listen (temporal). |
What are deeper in the brain fissures or sulci? | Fissures are deeper than Shallow Sulci - Remember the Cerebral Hemispheres are divided by LONG Deep fissure (Longitudinal Fissure) |
What are 3 classes of fiber tracts in the white matter of the Cerebrum? | 1. Association Tracts // 2. Commissural Tracts - Connects R and L cerebral Hemispheres // 3. Projection Tracts - Connects Cerebral cortex to diencephalon, brain stem, cerebellum, and spinal cord (Projector from cord onto big screen Cerebral cortex) |
Of the 3 classes of fiber tracts in the white matter of the cerebrum, the Association Tracts break down into what 2 tracts and what do they do? | 1. Arcuate Fibers - Connect Neighboring gyri w/in single cerebral lobe. /// 2. Longitudinal Fasciculi - Connect gyri b/t different cerebral lobes of same hemisphere. |
Cerebral Nuclei (basal nuclei) are paired gray matter inferior to the floor of the lateral ventricles, what are the names of these 5 areas? | Caudate Nucleus // Amygdaloid body // Lentiform Nucleus // Claustrum // Corpus Striatum |
What are the largest fiber tracts in the white matter of the cerebrum connecting two hemispheres? | Corpus Callosum / Commissural Tracts. |
What are the 3 divisions of the Diencephalon? | Epithalamus // Thalamus // Hypothalamus |
What projects into the longitudinal fissure and separates L and R cerebral Hemispheres? | Falx Cerebri//// Falx CerebELLI same thing for cerebellum |
What separates the lateral ventricles, its thin? | Septum Pellucidum |
The cerebrum is from by what embryological structure? | TELencephalon |
What is immediately anterior to teh central sulcus in the frontal lobe? | Pre-Central Gyrus |
Which cerebral lobe is involved with memory and interpretation of taste? | Insula |
Primary Olfactory Cortex provides conscious awareness of smell and is located in what cerebral lobe? | Temporal |
Gnostic Area integrates all sensory, visual, and auditory information and is composed of what three cerebral regions? | Parietal, Occipital, and Temporal Lobes |
What area of the brain is the master control of ANS, endocrine system, reg. of body temperature, emotional behavior, food intake, water intake, and Reg Sleep - wake rhythms? | Hypothalamus |
What 3 Regions form the brain stem? | Mesencephalon, Pons (meTencephalon), and Medulla Oblongata (mYELencephalon) |
the diencephalon includes what structures? | Everything with name "thalamus" and basal ganglia |

the diencephalon includes what structures? | Everything with name "thalamus" and basal ganglia |
With in the MB (mesencephalon) which structure can degenerate causing Parkinsons Disease? | Substantia Nigra |
The cerebellum develops from what structure? | METencephalon - The Pitcher (Pons) on the METs (METencephalon) make smooth coordinated movements (CEREBELLUM) when he pitches. |
