Which part of the respiratory system is responsible for producing the voice?
Which part of the respiratory system is responsible for producing the voice?
The larynx (plural: larynges), commonly called the voice box, is an organ in the neck of humans and most animals that is involved in breathing, sound production, coughing, and protecting the trachea against food aspiration during eating.
Which structures is responsible for the voice?
Larynx, also called voice box, a hollow, tubular structure connected to the top of the windpipe (trachea); air passes through the larynx on its way to the lungs. The larynx also produces vocal sounds and prevents the passage of food and other foreign particles into the lower respiratory tracts.
What airway structure has plates of cartilage?
trachea
The trachea is continuous with the larynx above and the two primary bronchi below. It is the supporting framework for 16-20 C-shaped hyaline cartilages. These cartilage “bracelets” are open on the posterior wall of the trachea adjacent to the esophagus.
What cartilages of the larynx play the most important in sound production?
The arytenoid cartilages are roughly pyramidal masses of cartilage that sit on top of the posterior side of the cricoid cartilage. These tiny cartilages play a vital role in the production of sound and act as the pivot points for the vocal folds and the muscles that move the vocal folds.

How are the cartilages of the larynx used in speech?
The arytenoid and corniculate cartilages function in speech, as explained shortly. A pair of cuneiform cartilages supports the soft tissues between the arytenoids and the epiglottis. A group of fibrous ligaments binds the cartilages of the larynx together and forms a suspension system for the upper airway.
Which is the largest supportive plate in the larynx?
The first three are solitary and relatively large. The most superior one, the epiglottic cartilage, is a spoon-shaped supportive plate in the epiglottis. The largest, the thyroid cartilage, is named for its shieldlike shape. It broadly covers the anterior and lateral aspects of the larynx.
What is the function of articular cartilage in joints?
The articular cartilage (AC), composed of hyaline cartilage tissue, plays an important role for joint functions; AC acts as a shock absorber, alleviates the friction between bones within joints, and maintains a biochemical homeostasis with the subchondral bone ( Sophia Fox et al., 2009).
How are bones connected by cartilage and fibrous tissue?
Fibrous – bones connected by fibrous tissue. Cartilaginous – bones connected by cartilage. Synovial – articulating surfaces enclosed within fluid-filled joint capsule. Synarthrosis – immovable. Amphiarthrosis – slightly moveable. Diarthrosis – freely moveable. A fibrous joint is where the bones are bound by a tough, fibrous tissue.
What is the function of cartilage in the body?
A Cartilage is a type of connective tissue that helps in providing support and maintaining structure or morphology of the body.
What is the name of the fibrous sheath of cartilage?
The cartilage fibrous sheath is called the perichondrium. The division of cells within cartilage occurs very slowly, and thus growth in cartilage is usually not based on an increase in size or mass of the cartilage itself.
Where are collagen fibers found in elastic cartilage?
Collagen fibers of the type found in hyaline cartilage are also present in elastic cartilage but are masked. Deep in the cartilage, elastic fibers form a dense, closely packed mesh that blinds the ground substance, forming a loose network beneath the perichondrium and continuous with it.
What makes up the outer layer of hyaline cartilage?
Except for the free surfaces of articular cartilages, hyaline cartilage is enclosed by a specialized sheath of connective tissue called the perichondrium. The outer layers of the perichondrium consist of a well vascularized, irregular and dense connective tissue that contains elastic and collagen fibers and fibroblasts.
