The pharynx chamber serves both respiratory and digestive functions. Thick fibres of muscle and connective tissue attach the pharynx to the base of the skull and surrounding structures.
Why is the larynx called the voice box?
Larynx is known as voice box as it is responsible for the production for voice. The two vocal cords are streched across the larynx in such a way that its leaves narraw slit between them for passage of air and when lungs force air through this, the vocal cords vibrate and produce sound.
Is larynx and laryngopharynx the same?
The laryngopharynx, also referred to as the hypopharynx, is the most caudal portion of the pharynx and is a crucial connection point through which food, water, and air pass. Specifically, it refers to the point at which the pharynx divides anteriorly into the larynx and posteriorly into the esophagus.
What is the pharynx also known as?
The pharynx is most commonly referred to as the throat. It's a muscular tube that starts at the base of the skull behind the nasal cavity, and extends down to the larynx (voice box) and esophagus, the tube that leads to the stomach. Its primary functions play a role in both the digestive and respiratory systems.
Is trachea and larynx same?
Your trachea (TRAY-kee-uh) is a long, U-shaped tube that connects your larynx (voice box) to your lungs. The trachea is often called the windpipe. It's a key part of your respiratory system. When you breathe in, air travels from your nose or mouth through your larynx.
What is the larynx?
The larynx is also called the voicebox. It is in the neck, above the windpipe (trachea) and in front of the gullet (oesophagus). The windpipe is the tube that carries air to and from the lungs.

What is the voice box?
Larynx is commonly known as the voice box, as it is the particular organ that makes the sound out of exhaling air from the lungs. The larynx is located at the junction of the trachea and oesophagus, and it opens into the laryngopharynx. Apart from the main function of producing sound, larynx passively prevents food particles from entering into the respiratory system or the trachea by acting as a barrier. There are vocal cords in the larynx organised in such a way that a good audible sound is produced. These cords are held together by a set of nine cartilages inside the larynx. When the exhaling air being sent out of the lung, the vocal cords are vibrated and the sound is produced, and finally the tongue manipulates those into words. The speed of airflow inside the larynx controls the frequency, known as the pitch. According to the endocrinal and nervous changes, the pitch and the weight (loudness) of the voice or sound differ. The amphibians were the first known animals to have a larynx for sound production in terms of communication, but recent research studies have revealed that most of the fish species have their own means of sound production through larynx-like organs. However, in humans, the particular quality of the sound or voice is unique for each individual. In other words, no matter how a person tries to change his or her voice through many of the ways, the particular wave has a special quality that is unique to him or her. That means, the vocal cord vibrations and other structures related to larynx are unique for each individual.

What is Larynx?
The larynx is almost like an apparatus that is made up of the materials like that of cartilages, muscles, mucous membrane and ligaments. These elements have the capacity of guarding and securing the entrance to the lower respiratory passages such as bronchi, trachea, and lungs. The larynx is also known for one of its most significant features consisting of the vocal cords. In terms of its location, the larynx is almost located just below the pharynx because it functions while connecting the pharynx with that of the trachea. It helps in the functioning of both the vocal system and the digestive system. Therefore, it is considered a common passage or channel for swallowing and vocalization.

What is the purpose of the epiglottis?
Epiglottis cartilage: The main purpose of the epiglottis cartilage is to close off the larynx to food, drink and foreign substances. It ensures that only air enters the larynx. The epiglottis is located at the entry way to the larynx from the pharynx. When a person swallows, the larynx goes up and this closes the epiglottis cartilage. It allows food and drink to pass from the pharynx to the esophagus.
What is the main passageway for food, drink, and air into and out of the body?
The trachea, or windpipe, is the main passageway for food, drink and air into and out of the body. The trachea is about one inch in width and is held open by the 20 cartilagenous rings that hold it open. It is approximately four inches in length. The lower section of the trachea branches into two separate passageways for air known as the bronchi, which are the passageways that lead to the lungs. The upper portion of the trachea is divided into two passageways. Now the pharynx vs larynx will be discussed.

How many cartilages are in the larynx?
The larynx is held open by nine different cartilages. The cartilages are important because they hold the larynx open which allows air to pass through it. The cartilages are divided into two categories. There are the paired cartilages and the unpaired cartilages.
What is the function of the glottis?
The glottis is the middle section of the larynx. One of its main functions is housing the vocal cords. As such, it is primarily responsible for producing the sounds of the voice. The other main function of the glottis is to help prevent substances from reaching the lungs. It accomplishes this by causing coughing to occur. Anytime food, drink or a foreign substance moves past the epiglottis, the glottis causes coughing to help bring the substance back up and away from the lungs. The glottis is a very important structure of both the digestive and respiratory systems. It aids the epiglottis in making sure that everything goes in the correct direction when it comes to the larynx.
What is the ring of the larynx?
Cricoid cartilage: This is a ring that is composed of hyaline cartilage. It forms the lower wall of the larynx and helps to connect the larynx to the trachea. It is attached to the thyroid cartilage by a ligament.
