Document Summary
Label major anatomical structures and systems for speech, language and hearing. State physiological functions of these structures and systems. Describe essential physiological processes involved in speech production/hearing. Understand how impairments in 1+ systems cause communicative disabilities. Relate anatomy and physiology of these structures to professional responsibilities of slps and audiologists. Human anatomy involved in speech production is grounded in areas responsible for swallowing, breathing & coughing. (1) respiratory (2) laryngeal (3) articulatory. The respiratory system consists of the lungs, trachea, pharynx, oral and nasal passages, diaphragm and rib cage. The respiratory system is divided into upper and lower respiratory tract: upper respiratory >> oral and nasal cavities, pharynx, lower respiratory >> trachea, bronchi, lungs. Air is inhaled via the nasal cavity covered by a mucosal membrane with tiny ciliated hairs. Pharynx - hollow tube starting behind the nose and ending at the top of the trachea: serves a two-fold purpose:
