| Term | Definition |
|---|---|
| trachea | tube formed by cartilaginous rings |
| diaphragm | primary muscle of respiration |
| larynx | houses the vocal fold |
| phonate | to produce voice |
| what does the larynx sit on top of? | the trachea |
| laryngeal functions | breathing, airway protection, source of sound for voicing |
| thyroid cartilage | forms the anterior and lateral walls of the larynx |
| arytenoid cartilage | two small, pyramid shaped cartilages that sit on top of the cricoid and attach to the vocal folds |
| cricoid cartilage | top ring of the trachea, linked to thyroid and arytenoid cartilages |
| extrinsic muscles | attach to a site within the larynx and to a site outside the larynx |
| intrinsic muscles | both attachments are within the larynx |
| suprahyoid | above the hyoid cartilage, raise the larynx |
| infrahyoid | below the hyoid cartilage, lower the larynx |
| interarytenoid | adduct the vocal folds |
| lateral cricoarytenoid | rotates arytenoid cartilages to adduct vocal folds |
| posterior cricoarytenoid | only abductor of the vocal folds |
| cricothyroid | stretches vocal folds, helps adduct vocal folds |
| thyroarytenoid | adducts and tenses vocal folds |
| Bernoulli effect | when gasses or liquids move through a point of constriction, velocity airflow increases and air pressure decreases |
| pitch | determined by frequency at which vocal folds vibrate, your perception of F0 |
| outer ear | pinna funnels sounds into external auditory canal |
| soft palate (velum) | muscle on the roof of the mouth that opens and closes the nasal cavity |
| function of occipital lobe | visual processing |
| myelin | covers axons, sends out impulses generated within the neuron |
| function of frontal lobe | reasoning, planning, motor planning for speech, movement, emotions, and problem solving |
| cell body | contains the nucleus |
| function of parietal lobe | movement, orientation, recognition, and perception of stimuli |
| hard palate | roof of the mouth/the floor of the nose |
| Broca's area | located in the frontal lobe, word finding and speech production |
| axons | send out impulses generated within the neuron |
| central nervous system | all incoming stimuli and outgoing signals processed through it (brain and spinal cord) |
| Eustachian tube | runs from the middle ear to the pharynx |
