What is the difference between Anatomy and Physiology?
Anatomy= structure Physiology= function
The relatively immobile point of a muscle
origin
The relatively mobile point of a muscle
insertion
Type of tissue that forms a protective surface; makes up skin and mucus membranes
epithelial
Type of connective tissue known for its strength and elasticity
cartilage
Type of tissue that transmits information from the brain to the periphery and back
neural/nervous
Movement toward the midline; coming together
adduction
Movement away from the midline; moving apart
abduction
This muscle originates at the sternum and clavicle, courses superiorly, and inserts in the hyoid bone
sternohyoid
This muscle originates at the hyoid bone and courses upward to insert in the tongue (glossus)
hyoglossus
The hyoglossus contracts in the direction of the site of origin. What is its most likely function?
to pull the sides of the tongue down
A muscle contracts in the direction of the site of origin. What is the most likely function of the Sternohyoid?
to pull the hyoid bone down
The most important features of cartilage
strength and elasticity
System responsible for production of voiced sound
phonatory
System that amplifies sound produced by vocal folds
resonance
System that powers voiced sound production
respiratory
System that shapes sound into speech
articulatory
