Cerebrum
|
Hemispheres
|
Largest portion of brain with convolutions, fissures, sulci
|
See below
|
|
Cerebral Cortex
|
Outer 2-5mm; gray matter
|
See below
|
|
Primary Motor Cortex
|
Frontal Cortex/ PrecentralSulcus
|
Initiates all voluntary muscle movement
|
|
Broca’s Area
|
Left Frontal Cortex/ superior to temporal lobe
|
Initiates all voluntary muscle movement involved in speech
|
|
PrimarySomatosensoryCortex (PSC)
|
Parietal Cortex/
Postcentral sulcus
|
Interprets general sensations
|
|
Visual Cortex
|
Occipital Cortex
|
Vision
|
|
Auditory Cortex
|
Temporal Cortex
|
Hearing
|
|
Gustatory Cortex
|
Inferior/Lateral PSC
|
Taste
|
|
Association Areas
|
All four lobes
|
Many that make us us.
|
|
Corpus Callosum
|
Connects cerebral hemispheres
|
Transmits impulses between hemispheres
|
Diencephalon
|
Thalamus
|
Gray Matter inferior to fornix
|
Central relay station for incoming sensory impulses, except smell
|
|
Hypothalamus
|
Gray matter extending inferiorly from thalamus
|
Regulates homeostasis
|
Brain Stem
|
Midbrain
|
Superior Brain Stem/ Corpora Quadrigemina
|
Auditory/Visual Reflexes; Reticular Formation (RT)
|
|
Pons
|
Bulged region inferior to Midbrain
|
Pneumotaxic Center (rate of
|
|
Medulla (Oblongata)
|
Between pons and spinal cord
|
Autonomic Centers of
Cardiac, Vasomotor, and Respiratory (rhythm)
|
Cerebellum
|
______________
|
Below cerebrum and posterior to brainstem;
Arbor Vitae; White Matter within Gray Matter
|
Coordination of all muscle movements; balance and equilibrium
|
OTHERS
|
Basal Ganglia
|
Gray matter deep within cerebral hemispheres
|
Relay stations for outgoing motor impulses
|
|
Choroid Plexus
|
Superior to Fornix
|
Secretion of CSF
|
|
Ventricles
|
2 Lateral, 3rd, and 4th; Cavities within cerebrum and brain stem, lined byependymal cells and filled with CSF.
|
Circulation of CSF
|
|
ArachnoidGranulations
|
Finger-like projections that from the subarachnoid space into the dural sinuses
|
Reabsorption of CSF
|
|
Limbic System
|
Several closely related areas deep within brain
|
Emotions and circadian rhythm.
|
|
Reticular Formation
|
Within brain stem
|
Brain alertness
|
|
Hippocampus
|
Small, seahorse-shaped structure deep within temporal lobe
|
Creates, stores, accesses new knowledge and information
|
|
Olfaction Center
