Basal Ganglia
Give this one a try later!
-structures deep within the brain composed primarily of gray matter
-relay center
-consists of: globus pallidus, putamen, and caudate nuclei
-part of extrapyramidal system
Myoelastic-Aerodynamic Theory

1) Air flowing out of the lungs is stopped at closed VFs. Once subglottal
pressure is sufficient, VFs are blown apart.
2) Air rushes more quickly through open folds (smaller area) and causes
negative pressure that sucks folds back together.
, 3) this process is repeated extremely causing a vibratory pattern and
phonation

muscle at floor of chest cavity that separates abdomen and thorax. Plays
major role in breathing and is almost the only muscle used in passive
breathing.
Basal Ganglia Damage
Give this one a try later!
-unusual body postures
-dysarthria
, -changes in body tone
-involuntary and uncontrolled movements
Intercostals
Give this one a try later!
11 pairs of internal intercostals pull thorax down and in for exhalation, 11
pairs of external intercostals pull thorax up and out for inhalation
Central Nervous System (CNS)
Give this one a try later!
-composed of spinal cord and brain
-acts as a central center and command station
Frontal Lobe
Give this one a try later!
-makes up 1/3 of the brain
-involved in: formation of plans and intentions
-contains: primary motor cortex, supplementary motor cortex, and Broca's
area (for speech and language)
