Your larynx is made of:
- The cartilage that gives it structure.
- Ligaments that connect the areas of cartilage and attach your larynx to nearby structures.
- Membranes, which also help hold cartilage together.
- Muscles, which move your larynx while swallowing, help with breathing and produce vocal sounds.
What does the larynx do to help the body function?
It acts as a switch between the larynx and the esophagus to permit air to enter the airway to the lungs and food to pass into the gastrointestinal tract. The epiglottis also protects the body from choking on food that would normally obstruct the airway.
What does the larynx do in the digestive system?
Your larynx is part of your respiratory system. It’s a hollow tube that lets air pass from your throat (pharynx) to your trachea on the way to your lungs. It also contains your vocal cords and is essential to human speech, so it’s often called the voice box.
What does larynx do in the respitory system?
The larynx helps us:
- Breathe: The vocal cords open to let air through.
- Speak: The vocal cords close. As air passes through the vocal cords, they vibrate, helping create speech sounds.
- Swallow: The epiglottis (part of the supraglottis) drops down over the larynx. The vocal cords close to keep food out of the lungs.
What is the larynx job in the body?
What is the function of the larynx?
Channeling food into the digestive system. The larynx helps prevent choking when eating and drinking. When food is swallowed, a small flap called the epiglottis covers the opening of the larynx to keep food and drink from entering the airways.
How does the larynx affect the respiratory system?
Air passage in the respiratory system. The larynx helps provide smooth passage of air from the nasal cavity to the lungs. Air enters through the nose and mouth when a person inhales, and travels through the pharynx, larynx, and bronchi.
What is the voice box?

What is the larynx made of?
The larynx is a complex band of cartilage, ligament , and muscle as well as a mucous membrane. A hollow structure, it’s formed of three large sections of cartilage that are unpaired—the thyroid, cricoid, and epiglottis—as well as six smaller cartilages. Here’s a quick breakdown of the large cartilages: 1
What is the voice box?
Commonly called the voice box, the larynx is located on top of the neck and is essential for breathing, vocalizing, as well as ensuring food doesn’t get stuck in the trachea and cause choking. Sitting just in front of the esophagus, the vocal folds are located here, making this organ absolutely vital for phonation (making speech sounds). 1 It visibly moves up and down when people swallow. This part of the body can be subject to a number of significant medical conditions, including bacterial infection (laryngitis), laryngeal cancer, and vocal fold paralysis (VFP), which can seriously compromise function.
How many branches does the larynx have?
The primary laryngeal nerve has been observed to split into two or three branches, which affects where it accesses different structures, such as the cricothyroid joint. 2 These differences can have serious implications in surgery.
Which membrane connects the arytenoid cartilage to the epiglottic cartilage?
Finally, there are a couple free-hanging cartilages, the cuneiform cartilages, located in a membrane called the aryepiglottic membrane, which represents the upper margin of the membrane that connects the arytenoid cartilages to the epiglottic cartilage. 1 This is covered in mucus and forms a structure called the aryepiglottic fold.
Which cartilage is the largest in the larynx?
Thyroid cartilage: This largest cartilage in the larynx composes the front and side portions of its structure. The right and left halves (laminae) fuse in the midline to create a projection forward—the laryngeal prominence, which is commonly known as the Adam’s apple.
How long does larynx inflammation last?
This inflammation of the larynx can be chronic—that is, lasting over three weeks —or acute, with the former being more common. Symptoms of this condition include hoarse voice, pain, couching, and, in some cases, fever. Acute laryngitis is often the result of either viral or bacterial upper respiratory tract infection, with a significant number of cases resulting from fungal growth. Chronic cases tend to be the result of smoking, allergies, or stomach acid reflux. Those who use their voices often, such as singers, teachers, and those in other professions, may experience inflammation of the larynx due to overuse.
Where is the larynx located?
The larynx is a small structure of cartilage that connects the throat to the windpipe. It is found in the front of the neck and houses the vocal cords, producing speech sounds and contributing to respiration. . Many conditions can affect it, including laryngitis.
Which structure forms the inner surface of the larynx?
Intrinsic ligaments and membranes: These ligaments and membranes form internal connections between the various structures of cartilage that form the larynx. Mucous membrane: This membrane lines the inner surface of the larynx.
What is the tube shaped passageway that connects the throat (pharynx) to the windpipe (?
The larynx is a tube-shaped passageway that connects the throat (pharynx) to the windpipe (trachea).
Where is the epiglottis?
As a person matures, the larynx shifts backward and down the throat. In adulthood, it sits about halfway down the neck below the epiglottis and above the trachea, also known as the windpipe.
What are the soft tissue folds in the larynx?
Soft tissue folds. Finally, the hollow area inside the larynx contains two types of soft tissue folds: Vestibular folds: Also known as false vocal cords, these sit on top of the vocal folds and protect the larynx. As their name suggests, these folds do not produce sound.
What are the ligaments and membranes in the larynx?
Ligaments and membranes in the larynx include: Extrinsic ligaments and membranes: These ligaments and membranes attach the upper portion of the larynx to the hyoid bone and the lower part to the trachea. They sit on the outside of the larynx.
How big is the larynx?
The larynx is about 4–5 centimeters in length and width. Trusted Source. . Many conditions can affect it, including laryngitis. This article will explore the location, anatomy, and purpose of the larynx. It will then list and explain several conditions that can affect it.
Where is the larynx located?
Where is the Larynx (Voice Box) Located. The flexible structure is located at the anterior side of the neck, in front of the pharynx and above the windpipe [2]. Suspended from the hyoid bone, it extends from C3 to C6, opening into the laryngeal portion of the pharynx [3]. Larynx Diagram.
What is the larynx made of?
Anatomy of the Larynx. It is made up of multiple pieces of tough cartilage, surrounded and held together by fibrous tissues, membranes, and ligaments [3]. The largest cartilaginous segment is called the thyroid cartilage, with a prominent bulging known as Adam’s apple. The semicircular structure has a raised ridge on its anterior surface, ...
What is the voice box?
The larynx, commonly called the voice box, is a 2-inch long cartilaginous tube connecting the back of the nose ( pharynx) and the windpipe ( trachea) with each other. It is one of the most important structures of the respiratory system, also playing a crucial role in the production of speech in humans [1].
What is the function of the epiglottis?
