Outline 12 - Pharynx Flashcards
Anatomy and Physiology of speech and language is divided into 4 systems 1. 2. 3. 4.
- neurology
- motor for voice
- vibratory source (larynx)
- resonator source (pharynx)
Nervous system functions as 1. - registers sensory data 2. - effector, to create behavior 3. - processing 4.
- sensor
- motor
- integrator
- regulator
Skeletal framework for respiration
Vertebral column, Rib Cage, Shoulder girdle, Pelvic girdle
Organs of respiration 1. 2. 3. 4. 5. 6.
- Nose
- Pharynx
- Larynx
- Trachea
- Bronchi
- Lungs
muscles of respiration
1.
2.
3.
- diaphragm
- External Intercostal Muscle
- Intercostal muscles
what are the muscles that shape glottis and affect vibratory behavior of vocal fold (hint: intrinsic muscles)
i. Thyroarytenoid – 2 parts
1. thyromuscularis
2. thyrovocalis
ii. Posterior cricoarytenoid – 2 layers
iii. Lateral cricoarytenoid
iv. Interarytenoid – 2 parts
1. oblique part
2. transverse part
v. Cricothyroid muscle – 2 parts
1. pars oblique
2. pars recta
resonance helps with
shaping of vibratory sound that comes from true vocal fold
3 parts of Pharynx
1.
2.
3.
- Laryngopharynx
- Oropharynx
- Nasopharynx
Functions of Pharynx
- Air passage from mouth and nose to lungs via pharynx, larynx, trachea
- Food passage from mouth to stomach via pharynx, esophagus. Changes in size and shape for swallowing
- Changes in size and shape of pharynx for speech
constrictors move in a ______ manner
peristaltic
list the 3 pharyngeal constrictors
1.
2.
3.
- inferior
- middle
- superior
Inferior pharyngeal constrictor:
a. origin:
b. insertion:
c. overlap:
a. thyroid and cricoid cartilage
b. midline ralph
c. all constrictor overlap each other
Middle pharyngeal constrictor:
a. Origin
b. Insertion
c. . Overlap
a. hyoid bone
b. midline raphe
c. superior pharyngeal constrictors
Middle pharyngeal constrictor is ____ shaped
fan
true or false.
“superior pharyngeal constrictor helps squeeze the velum to close off the nasal cavity to create negative pressure and get food in the esophagus”
true
