bescribe the production of sound in humans give the role of tounge in the production of sound
Answers
Answer:
Velar sounds (also known as velum) involve the back of the tongue moving towards the soft palate that lies behind the palate itself (ref4). ... Glottal sounds are produced by putting pressure on the airflow in the glottis by closing and pivoting vocal cords.
Answer:
of swallowing. The quick movements of the tongue, necessary for rapid delivery of tongue twisters for example, require very delicate control of the action of the tongue. This control is often best regulated in concert with the ear, listening to the sounds created by the voice when the tongue is in one position over another. Sensitivity is the key to learning to appreciate the range of capabilities the tongue possesses.
Landmarks:
Tip, front edge, blade, middle, back of tongue
Median fibrous septum
Eight muscles of the tongue, divided into intrinsic & extrinsic muscles
Tip:
the very point of tongue
Front edge:
awareness is essential for delicate control of alveolar plosives, such as /t, d/
Blade:
that part that is free to flap up and down, the front third
Middle:
just behind the blade
Back:
the surface of the tongue begins to change here; awareness is important for certain back vowels
Median Fibrous Septum: Medianibrous Septum:
a divider that runs down the centre of the tongue serves as an attachment for the transverse muscles.
Intrinsic Muscles of the Tongue:
The image at left features the important muscles of the body of the tongue. The transverse muscle fibers are hard to see because they can only be seen in cross-section as little dots running under the longitudinal muscles. Also visible in this image is the genioglossus, which joins the tongue to the chin and the geniohyoid, which joins the chin and hyoid bone.
Inferior and Superior Longitudinal Muscle:
go the length of the tongue
moves tip up and down
Transverse Muscle:
go across the tongue
narrows and lengthens the tongue
Vertical Muscle:
go up and down in the tongue
flattens and depresses the tongue
Extrinsic Muscles:
Extrinsic muscles of the tongueThis side view of the extrinsic muscles gives and excellent idea of how big the "roots" of our tongues are. You can feel these muscles by pressing a fingertip under your chin, up towards the tongue. Those muscles should be soft and gooey, especially during phonation.
Genioglossus: chin to tongue
sticks out the tongue
presses against the teeth or alveolar ridge
pulls the tongue tip back
troughs the tongue
Styloglossus: styloid process behind ear to tongue
pulls the tongue upward and back
Palatoglossus: palate to tongue
pulls the tongue back to grove the tongue
Hyoglossus:hyoid bone to tongue
retracts or depresses the tongue
elevates the hyoid bone
