vocal cords

(noun)

Two folds of tissue located in the larynx that vibrate when air passes over them, producing the sound waves associated with talking and singing.

Examples of vocal cords in the following topics:

  • CLASSIFICATION OF SOUNDS

    • a) p, t, c, k, q are voiceless,[4] i.e. sounded without voice or vibration of the vocal cords.
    • b) b, d, g are voiced,[5] i.e. sounded with vibration of the vocal cords.

  • Laryngitis and Cancer of the Larynx

    • It causes hoarse voice or the complete loss of the voice because of irritation to the vocal folds (vocal cords).
    • It is caused by acid reflux disease, allergies, bacterial or fungal infection, excessive coughing, smoking, or alcohol consumption, inflammation due to overuse of the vocal cords, use of inhaled corticosteroids for asthma treatment, or viral infection.
    • At times, persistent hoarseness or loss of voice (dysphonia) is a result of vocal cord nodules in which case physicians may recommend a course of treatment that may include a surgical procedure and/or speech therapy.
    • For the purposes of tumor staging, the larynx is divided into three anatomical regions: the glottis (true vocal cords, anterior and posterior commissures); the supraglottis (epiglottis, arytenoids and aryepiglottic folds, and false cords); and the subglottis.
    • The apparent extensive exophytic change involves the epiglottis and the vocal cords.

  • Larynx

    • These folds are false vocal folds (vestibular folds) and true vocal folds (folds).
    • The false vocal folds are covered by respiratory epithelium, while the true vocal folds are covered by stratified squamous epithelium.
    • These false vocal folds do not contain muscle, while the true vocal folds do have skeletal muscle.
    • The two sets of folds are separated by the vocal ligament, with the false vocal folds above, and the true vocal cords below the ligament.
    • The true vocal folds are often referred to as the vocal cords, however the folds technically aren't cords.

  • Anabolic Steroids and Muscles

    • Anabolic steroids also have androgenic and masculinity-enhancing properties, including the development and maintenance of masculine characteristics such as the growth of the vocal cords, testicles and body hair (secondary sexual characteristics).

  • Spinal Cord

    • A cross-section of the spinal cord looks like a white oval containing a gray butterfly-shape .
    • The spinal cord also controls motor reflexes.
    • In the United States, there around 10,000 spinal cord injuries each year.
    • Because the spinal cord is the information superhighway connecting the brain with the body, damage to the spinal cord can lead to paralysis.
    • The extent of the paralysis depends on the location of the injury along the spinal cord and whether the spinal cord was completely severed.

  • Overview of the Spinal Cord

    • The brain and spinal cord together make up the central nervous system (CNS).
    • The dura mater is the outermost layer of spinal cord tissue, forming a tough protective coating.
    • The spinal cord is divided into cervical, thoracic, and lumbar regions.
    • The nerves of the lumbosacral spinal cord supply the pelvic region, legs, and feet.
    • Thirty-one pairs of spinal nerves (sensory and motor) branch from the human spinal cord.

  • Spinal Cord Trauma

    • A spinal cord injury (SCI) refers to any injury to the spinal cord that is caused by trauma and not disease.
    • A spinal cord injury (SCI) refers to any injury to the spinal cord that is caused by trauma instead of disease.
    • An incomplete spinal cord injury involves preservation of motor or sensory function below the level of injury in the spinal cord.
    • Because the spinal cord is so dependent on the structural integrity of the spine, if anything happens to the spine, the cord can be crushed or severed.
    • Autonomic dysreflexia (AD) occurs most often in spinal cord-injured individuals with spinal lesions above the T6 spinal cord level, although, it has been known to occur in patients with a lesion as low as T10.

  • Spinal Cord Compression

    • Spinal cord compression occurs when the spinal cord is compressed by bone fragments.
    • Spinal cord compression develops when the spinal cord is compressed by bone fragments from a vertebral fracture, a tumor, abscess, ruptured intervertebral disc, or other lesion .
    • The most common causes of cord compression are tumors, but abscesses and granulomas (e.g. in tuberculosis) are equally capable of producing the syndrome.
    • Dexamethasone (a potent glucocorticoid) in doses of 16 mg/day may reduce edema around the lesion and protect the cord from injury.
    • In spinal cord compression, the spinal cord (shown here) may be compressed by bone fragments from a vertebral fracture, a tumor, abscess, ruptured intervertebral disc, or other lesion.

  • Dialect and Vocal Variety

    • Speakers may use many different English dialects to change the pitch, rate, volume, and use of pauses to achieve vocal variety.
    • Vocalics, or paralanguage, is one way we communicate orally, but vocalics is nonverbal.
    • You achieve vocal variety by using any or all of the features of vocalics: the rate, pitch, volume and pauses you use to change the way you deliver your message.
    • All of these vocal changes in paralanguage help you emphasize what is more important compared to another part that is less important.
    • Employ vocal variety to emphasize key points in your speech and use dialect to relate to your audience
