10 Questions
Name the structure that extends from the hyoid bone to the cricoid cartilage.
laryngopharynx
What is the location of sinuses?
Larynx
Which cartilage in the larynx is the only complete cartilaginous ring?
Cricoid cartilage
What is the function of the surfactant in the lungs?
It secretes surfactant which helps to reduce surface tension and prevent the alveoli from collapsing
What is the term for the maximum volume of air that can be exhaled forcibly after a normal exhalation?
Forced expiratory volume (FEV1)
What is the function of the hyoid bone?
The hyoid bone is a bone in the neck that supports the tongue and provides attachment for various muscles involved in swallowing and speech.
What is the purpose of the sinuses?
The sinuses are air-filled spaces in the skull that help to lighten the weight of the skull and produce mucus to moisturize and filter the air we breathe.
What is the role of the cricoid cartilage in vocal cord movement?
The cricoid cartilage is a ring-shaped cartilage in the larynx that helps to control the tension and position of the vocal cords, allowing for vocalization and speech.
What are the functions of the lungs?
The lungs are responsible for the exchange of oxygen and carbon dioxide in the body, as well as the production of surfactant, a substance that helps to reduce surface tension and prevent the collapse of the alveoli.
What is dead space in the respiratory system?
Dead space refers to the parts of the respiratory system, such as the trachea and bronchi, where air does not participate in gas exchange with the blood.
Study Notes
Respiratory System
- The structure that extends from the hyoid bone to the cricoid cartilage is the thyroid cartilage.
Anatomy of the Larynx
- The only complete cartilaginous ring in the larynx is the cricoid cartilage.
Sinuses
- Sinuses are located in the skull, specifically in the facial bones.
- The purpose of the sinuses is to warm, humidify, and filter the air we breathe.
Hyoid Bone
- The function of the hyoid bone is to serve as an attachment point for muscles of the tongue, larynx, and pharynx.
Lungs
- The functions of the lungs include exchanging oxygen and carbon dioxide through the process of respiration.
- Surfactant in the lungs reduces the surface tension of water, allowing the lungs to expand more efficiently.
- Dead space in the respiratory system refers to the volume of air that is not involved in gas exchange.
Respiratory Volumes
- The term for the maximum volume of air that can be exhaled forcibly after a normal exhalation is forced expiratory reserve (FER).
Cricoid Cartilage
- The cricoid cartilage plays a role in vocal cord movement, as it forms the base of the larynx and provides an attachment point for the vocal folds.
