The larynx is situated between the buccal cavity and the windpipe (trachea). During swallowing, the larynx shifts upwards and is shut by a trapdoor, the epiglottis. The vocal cords are also shut to stop the food from entering the lungs.
The vocal cords are situated at the base of the larynx and are a pair of fibrous tissues. The vocal cords come together and tighten to facilitate the process of speaking. Words are produced by forcing air into the larynx and then modulating by the lips and the tongue. The pitch of the voice is controlled by changing the tension in the vocal cords. The cricopharyx is the narrowest part of the esophagus and is positioned behind the larynx. The cricopharyx is the part where foreign particles are most likely to get stuck.
The thyroid gland is positioned in front of the larynx and is responsible for producing hormones that regulate the metabolism of a body. Along with the thyroid, parathyroid glands also help in maintaining the well-being of the body. Below the jawbone (mandible) on each side lies the submandibular gland, and in front of the pinna lies on each side parotid glands. Many glands, along with the mentioned ones, maintain the moisture in our oral cavity. Lymph Nodes are the small nodular structures on either side of the neck. They form the lymphatic system along with lymphatic tubes. The Lymphatic system drains the debris from our body. Lymph Nodes are not noticeable until they get swollen up.
