Brain Anatomy Flashcards
Corpus callosum
connects right and left hemispheres and allows communication between them
Diencephalon (nickname and what its comprised of)
The thalamus family. Made of the thalamus, hypothalamus, epithalamus (choroid plexus and pineal gland)
Brain stem (what its comprised of)
Pons, midbrain, medulla oblongata
Thalamus
Transfers impulses to correct cortex for interpretation
Hypothalamus
-Important autonomic and limbic/emotional system
-controls water balance
regulates metabolism
Epithalamus (composed of what 2 structures)
Choroid plexus and pineal gland
Choroid plexus
Produces cerebrospinal fluid (CSF)
Pineal gland
Circadian rhythm (sleep/wake cycle)
Midbrain
Important role in motor movement, auditory and visual processing
Pons
“first hill”. Regulates breathing
Medulla oblongata
“second hill”. regulate HR, BP, swallowing and vomiting
Spinal cord
Sends and receives neural impulses
Cerebral hemisphere/cerebrum (what its comprised of)
Frontal lobe, temporal lobe, occipital lobe, and parietal lobe
Frontal lobe
Cognitive skills (problem solving), language speech, and emotion expression
Temporal lobe
Language comprehension, hearing, and memories
Parietal lobe
Processing of sensory info (smell, touch, taste)
Occipital lobe
Processing of vision
Cerebellum (seperate from cerebrum)
“little brain”. coordination of involuntary and involuntary movements such as balance, timing, and posture
Gyrus
Hills/ridges
Fissure
Deep sulcus. separates lobes of brain
Sulcus
Indentation
Gray matter
Unmyelinated neurons. Storage of memory
White matter
Myelinated neurons.
