  1. Anatomy and Physiology of the Speech Mechanism Lisa Kopf Fall 2012

  2. The Speech Mechanism Zemlin, W.R. (1998). Pg. 32.

  3. Four Speech Systems • Respiratory • Phonatory • Resonance • Articulatory

  4. Respiratory System • Respiration (breathing) • Phonation (voicing) • Resonance (influencing voice) • Articulation (speech sounds)

  5. Phonatory System • Respiration (breathing) • Phonation (voicing) • Resonance (influencing voice) • Articulation (speech sounds)

  6. Resonance System • Respiration (breathing) • Phonation (voicing) • Resonance (influencing voice) • Articulation (speech sounds)

  7. Articulatory System • Respiration (breathing) • Phonation (voicing) • Resonance (influencing voice) • Articulation (speech sounds)

  8. Respiratory SystemLecture 1 Lisa Kopf Fall 2012

  9. The Respiratory System http://www.easyrent.tj/001_lib/002_anatomy_3d/3d_models/human_anatomy/male_systems/Male_Respiratory_3.php

  10. Upper Airway http://www.easyrent.tj/001_lib/002_anatomy_3d/3d_models/human_anatomy/male_systems/Male_Respiratory_3.php

  11. Upper Airway • Nasal cavity • Oral cavity • Pharyngeal cavity • Filter, moisten, warm air http://web.carteret.edu/keoughp/LFreshwater/NEO/blackboard/Pediatric%20Diseases/

  12. Respiratory Passage http://academic.kellogg.edu/herbrandsonc/bio201_mckinley/Respiratory%20System.htm

  13. Larynx/Vocal Folds • Larynx • Houses the vocal folds • Vocal folds • Valve air • Protective mechanism • Paradoxical Vocal Fold Movement (PVFM) or Vocal Cord Dysfunction (VCD) http://www.homebusinessandfamilylife.com/larynx.html http://www.webmd.com/a-to-z-guides/normal-vocal-cords

  14. Trachea • Cricotracheal ligaments • 11-12 cm long • 2-2.5 cm diameter • 16-20 rings http://www.naturalhealthschool.com/bronchi_trachea.html

  15. Trachea • Intratracheal membrane: • Connects tracheal rings • Allows for movement • Trachealis muscle • Mucous membrane: • Goblet cells • Cilia in trachea • Carina http://www.getbodysmart.com/ap/respiratorysystem/tracheabronchi/trachea/tracheawall/tutorial.html http://www.naturalhealthschool.com/bronchi_trachea.html

  16. Bronchi • Primary/main stem bronchi • Secondary/lobar bronchi • Tertiary/segmental bronchi Zemlin, W.R. (1998). Pg. 36.

  17. Branches of the Bronchi • Right Primary Bronchus • 3 secondary bronchi • 10 tertiary bronchi • Left Primary Bronchus • 2 secondary bronchi • 8 tertiary bronchi Zemlin, W.R. (1998). Pg. 38.

  18. Bronchioles • 1 mm or less diameter • Terminal bronchioles: communicate directly with the alveoli http://www.easyrent.tj/001_lib/002_anatomy_3d/3d_models/human_anatomy/male_systems/Male_Respiratory_3.php

  19. Alveoli • Tiny air-filled sacs • 300-600 million in one person’s lungs • Clustered together at terminal bronchioles Hixon, T.J., et al. (2008). Preclinical Speech Science: Anatomy, Physiology, Acoustics, and Perception. Pg. 12.

  20. Movie- Respiratory Anatomy http://www.youtube.com/watch?v=HiT621PrrO0 http://people.eku.edu/ritchisong/301notes6.htm http://www.youtube.com/watch?v=3nZaSrV6v6k&feature=related

  21. Mediastinum • Separates the lungs • Mediastinum contains: • Heart • Part of esophagus • Part of trachea • Nerve tracts • Blood vessels

  22. Lungs http://www.anatomy-resources.com/human-anatomy/sh331.htm

  23. Pleurae • Consists of 2 membraneous layers • Visceral pleura • Parietal pleura • Layers are held together by intrapleural fluid pressure

  24. Lung Volumes and Capacities • Total Lung Capacity (TLC) • Women: 5 liters • Men: 6 liters

  25. Lung Volumes and Capacities • TV = Tidal Volume • VC = Vital Capacity • IRV = Inspiratory Reserve Volume • ERV = Expiratory Reserve Volume • IC = Inspiratory Capacity • RV = Reserve Volume • FRC = Functional Residual Capacity • TLC = Total Lung Capacity http://www.youtube.com/watch?v=y9eiVqddVVo&feature=related
