Updated.
CNS - Answer Integrative Functions (interpretation of sensory info)
PNS - Answer sensory + motor functions
Telencephalon --> Cerebrum
Diencephalon --> Diencephalon - Answer What are the secondary brain vesicles and structures
of the mature brain for the Forebrain?
Mesencephalon --> Brainstem: Midbrain - Answer What are the secondary brain vesicles and
structures of the mature brain for the Midbrain?
Metencephalon --> Brainstem: Pons/Cerebellum
Myencephalon --> Brianstem: Medulla Oblongata - Answer What are the secondary brain
vesicles and structures of the mature brain for the Hindbrain?
Cerebrum/Cerebral Hemispheres - Answer interpretation of sensory stimuli and planning
movement
Diencephalon - Answer relays info; regulate biological rhythms; maintain homeostasis
Brainstem - Answer maintain homeostasis; controls some reflexes; monitors movement;
integrate info
Cerebellum - Answer monitor and coordinate ongoing movement (fine motor units)
White Matter - Answer myelinated; carries out signals; centralized in the brain
Gray Matter - Answer non-myelinated; processing; centralized in the spinal chord
Ventricles - Answer hollow chambers filled with CS fluid (important for support)
ependymal cells - Answer What are ventricles lined with?
,Lateral Ventricles (R/L) - Answer within the cerebral hemisphere; separated by the septum
pellucidum
Third Ventricle - Answer in the diencephalon; connected via the interventricular foramen
Fourth Ventricle - Answer in the hindbrain; connected via the cerebral aqueduct through the
midbrain
Gyri - Answer elevated ridges of tissue
Sulci - Answer shallow grooves
Central Sulcus - Answer frontal/parietal
Parieto-Occipital Sulcus - Answer occipital/parietal
Lateral Sulcus - Answer temporal/frontal/parietal
5 - Answer How many lobes does the brain have?
Frontal Lobe - Answer planning; personality
Parietal Lobe - Answer sensory integration; attention
Temporal Lobe - Answer hearing; language; memory; emotion
Occipital Lobe - Answer visual info processing
Insular Lobe - Answer forms part of floor (deep)
Fissure - Answer deeper groove
Longitudinal Fissure - Answer separates the cerebral hemispheres
, Transverse Cerebral Fissure - Answer separates the hemisphere from the cerebellum
Cerebral Cortex - Answer where consciousness resides (composed of gray matter)
Contralateral - Answer opposite sides of the body
Neocortex - Answer newest layer; only in mammals
Primary Motor Cortex - Answer controls voluntary movement
Primary Sensory Cortices - Answer conscious awareness of sensation
Broca's Area - Answer speech production
Wernicke's Area - Answer language comprehension
Primary (Somatic) Motor Cortex - Answer located in the precentral gyrus of the frontal lobe
Premotor Cortex - Answer anterior to the precentral gyrus; sequences basic motor
movements into complex tasks
Frontal Eye Field - Answer anterior to promotor cortex; voluntary movement of the eyes
Primary Somatosensory Cortex - Answer postcentral gyrus; receive info, spatial discrimination,
somatosensory homunculus
skin - Answer Somatic sensory receptors in the ___
muscles/joints/tendons - Answer Proprioceptors in the ___
Somatosensory Association Cortex - Answer integrates sensory input from primary
somatosensory cortex
Primary Visual Cortex - Answer occipital lobe; receives info from the retina and leads to the
visual association area
