Where are the CNS motor control of the larynx?
Motor cortex, primary motor strip, midbrain, brainstem
Preplanning
Brocas (vocal response)
Motor planning for voice
insula
voice production
precentral gyrus
sensory info for vocalizing (motor)
Basal Ganglia/thalamus
Basal Ganglia/thalamus

What are the centers in the CNS?
BBB PP MMIT
Basal ganglia/thalamus, Broca’s area, brainstem, Precentral gyrus, Primary motor strip,Motor cortex midbrain, Insula, Temporal Lobes,
CNs of phonation and voice
Glossopharyngeal, Vagus, Spinal Accessory, Hypoglossal
Glossopharyngeal (IX)
motor to stylopharyngeus m.
Stylopharyngeus
elevates the larynx (IX)
Vagus
(X) SLN, RLN: sensory and motor to larynx, motor to the thorax
Spinal Accessory
(XI) neck accessory m.’s (SCM & trao) levator veli palatine and uvula
Hypoglossal
(XII) depression/elevation of larynx (via toungue m.’s) neck strap m’s
Vagus branches”
2 SLN & RLN
SLN: sensory (internal branch) & motor to cricoid thyroid M (external branch)
RLN:
Right: loops behind R carotid & R subclavian
Motor: TA, PCA, LCA, transverse and obliques Left: loops around aortic arch
List some Neurogenic eitiology categories
Congenital, Lesion/tumor/dz, trauma
Lower motor neuron disorders
VF paralysis, MG, Guillaine-Barre, Flacccid Dysarthria
Upper motor neuron
Spastic dysarthria, Hypokinetic Dysarthria (PD), Hyperkinetic dysarthria, ataxic
Hyperkinetic dysarthria
SD & essential tremor
what is the #1 type of hyperkinetic
spasmodic dysphonia
