Brain Parts Flashcards
Cerebral cortex
Outer shell of gray matter
Deeper region of myelinated tracts that connect brain areas together
Also connect spinal cord
White matter tracts
White matter tracts made of:
Myelinated axons that connect parts together
White matter tracts send info to:
Frontal lobe
Corpus callosum
Group of white tracts
Connect left and right cerebral hemispheres
C-shaped
Cingulate gurus
Immediate ridge, superior to corpus callosum
House part of emotional centers
Cingulate gyrus
Diencephalon
Region of brain that looks like duck
Structures lateral of third ventricle
Thalamus function
Routes all sensations other than smell to proper area of brain
Routes all motor stimulus to proper spinal region
Thalamus position
Oval mass of gray matter superior to brain stem
Diencephalon
Intermediate mass function
Stabilizing rod that connects left and right thalamus
Intermediate mass location
Small dot in center of thalamus
Diencephalon
Pineal gland function
Neuroendocrine that controls cyclical (sleep) behaviors
Stimulated by light and releases melatonin
Pineal gland location
Very top of thalamus
Diencephalon
Hypothalamus function
Regulates hunger, thirst, and body temperature
Hypothalamus location
Inferior to thalamus
Diencephalon
With thalamus, helps make area called midbrain
Pituitary gland function
Endocrine gland that releases hormone
Pituitary gland location
Inferior to hypothalamus
Small wire that suspends pituitary gland
Hypophyseal stalk
Pons
Controls consciousness
Swelling anterior to cerebellum on brain stem
Medulla oblongata
Inferior most part of brain stem
Cerebellum
Controls motor skills and predicts body position/strength
Cerebellum position
Posterior, inferior most part of brain.
Left and right sides of cerebellum
Cerebellum hemisphere
Narrow strip that connects cerebellum
Vermis
Arrangement of white matter inside cerebellum. Looks like tree of life.
Arbor vitae
Choroid plexus
Network flow of cerebrospinal fluid
Two c-shaped/ largest cavity for CSF
Lateral ventricles
Tiny hole, connecting lateral ventricle to third ventricle
Interventricular foremen
Small space formed between the thalamus that holds CSF
Third ventricle
Narrow passageway through which CSF flows through the brain stem
What is it’s positioning?
Cerebral aqueduct of Sylvius
Inferior to third cavity
Triangular cavity anterior to cerebellum. CSF flows through
Fourth ventricle
