Understanding the Larynx and Phonation

The framework of the larynx includes all major structures and muscle attachments. Which of the following is NOT a part of the larynx framework?

• Thyroid cartilage

• Cricoid cartilage

• Hyoid bone

• Femur

The intrinsic and extrinsic membranes of the larynx are described as:

• Intrinsic membranes are located within the larynx, while extrinsic membranes connect the larynx to other structures.

• Intrinsic membranes connect the larynx to other structures, while extrinsic membranes are located within the larynx.

• Both intrinsic and extrinsic membranes are located within the larynx.

• Both intrinsic and extrinsic membranes connect the larynx to other structures.

The origins and insertions of the intrinsic and extrinsic muscles of the larynx are:

• a) Only intrinsic muscles originate and insert within the larynx.

• b) Extrinsic muscles originate outside the larynx and insert into it.

• c) Both intrinsic and extrinsic muscles originate and insert outside the larynx.

• d) Intrinsic muscles originate outside the larynx and insert into it.

The structure of the vocal folds is:

• Muscle and ligament

• Bone and cartilage

• Tendon and skin

• Nerve and blood vessel

The function of intrinsic and extrinsic muscles of the larynx is to:

• Control the pitch and volume of the voice

• Aid in digestion

• Regulate blood circulation

• Support the immune system

Phonation is initiated, sustained, and terminated by which of the following processes?

• Vocal fold vibration

• Respiratory control

• Neural feedback

• All of the above

Which of the following describes the physiology of phonation, including laryngeal adduction, abduction, and pitch control?

• The process involves the movement of the vocal cords to produce sound.

• Phonation is controlled by the diaphragm and abdominal muscles.

• It is the regulation of airflow through the nasal cavity.

• Phonation is unrelated to laryngeal movements.

The relationships between length, mass, and tension in the vocal folds impact pitch by:

• Increasing length and mass lowers pitch, while increasing tension raises pitch.

• Increasing length and tension lowers pitch, while increasing mass raises pitch.

• Increasing mass and tension raises pitch, while increasing length lowers pitch.

• Increasing length, mass, and tension all raise pitch.

The physiology of phonation in regards to speech production involves which of the following processes?

• Vibration of the vocal cords

• Movement of the tongue

• Breathing through the nose

• Chewing food

The source-filter theory explains how the human vocal tract shapes sound. Which of the following elements are related to this theory?

• Formants, spectra, and spectrograms

• Pitch, tone, and volume

• Rhythm, melody, and harmony

• Amplitude, frequency, and wavelength
