Anatomy, Neuroanatomy, & Physiology Flashcards
diaphragm
thick, dome-shaped muscle,
separates the abdomen from the thorax
efferent neurons
transmit info AWAY from the brain
hypothalamus
controls emotions
thalamus
relays sensory impulses to various portions of the cerebral cortex
diencephalon
important structure adjacent to the brainstem,
contains hypothalamus & thalamus
corpus striatum
composed of 3 nuclear masses:
globus pallidus,
caudate nucleus,
putamen
cerebellum
critical to speech production,
helps coordinate & regulate neural impulses to & from brain,
regulates: body posture, equilibrium, & coordinated fine-motor movements
anterior cerebral artery
anterior cerebral artery supplies blood to the
corpus callosum
& basal ganglia
aryepiglottic folds
aryepiglottic folds composed of a ring of connective tissue & muscle extending from the tips of the arytenoid cartilages to the larynx,
separate the laryngeal vestibule from the pharynx,
help preserve the airway
CN X
the vagus innervates the: larynx, levator veli palatini, palatoglossus, palatopharyngeus
palatoglossus
contributes to velopharyngeal closure
through elevating & depressing the velum
tensor veli palatini
contributes to velopharyngeal closure through tensing the velum
levator veli palatini
contributes to velopharyngeal closure through elevating the velum
lingual frenum
structure at the inferior portion of the tongue,
connects the tongue with the mandible
genioglossus
muscle that is most involved when producing voiced & voiceless /th/
cerebellar damage
ataxia
dysarthria
brainstem
midbrain, pons, medulla,
connects spinal cord with the brain
via diencephalon
brain structures
brainstem, reticular activating system, diencephalon, basal ganglia, cerebellum, cerebrum (cerebral cortex)
meninges
consist of the:
dura mater,
pia mater,
& arachnoid
corpus callosum
commissural fiber
connects the 2 cerebral hemispheres
