  • Front
  • Back
Trachea
The windpipe; a tube that connects the pharynx or larynx to the lungs, allowing the passage of air.
Laryngopharynx
The posterior part of the pharynx; it that connects to the esophagus. inferior to the epiglottis and extends to the location where this common pathway diverges into larynx and oesophagus
Hard Palate
Thin horizontal bony plate of the skull, located in the roof of the mouth.
Ethmoid bone
Separates the nasal cavity from the brain
Cricoid Cartilage
Sits just inferior to the thyroid cartilage in the neck. Provide attachments for the various muscles, cartilages, and ligaments involved in opening and closing the airway and in speech production.
Uvula
The conic projection from the posterior edge of the middle of the soft palate
Oropharynx
Oral part of the pharynx, reaches from the Uvula to the level of the hyoid bone.
Vestibular fold
(Or false vocal cord) Lubricate the vocal folds with mucous and help prevent food from entering lower respiratory tract organs
Nasal vestibule
The most anterior part of the nasal cavity. Inside it are small hairs called vibrissae, which filter dust and other matter that you breathe in.
Lingual tonsils
Rounded masses of lymphatic tissue that cover the posterior region of the tongue. Fights infection and swells when infected
Nasal meatuses
Canals/openings in nose
Nasal Conchae
long, narrow and curled bone shelf (shaped like an elongated sea-shell) that protrudes into the breathing passage of the nose.
Soft Palate
Soft tissue constituting the back of the roof of the mouth. Responsible for closing off the nasal passages during swallowing, and closing off the airway.
Thyroid gland
Located inferior to cricoid cartilage. Controls how quickly the body uses energy, makes proteins, and controls how sensitive the body is to other hormones.
Posterior nasal apertures
It is the opening between the nasal cavity and the nasopharynx.
Palatine Tonsils
The tonsils that can be seen on the left and right sides at the back of the throat.
Thyroid cartilage
Forms the bulk of the anterior wall of the larynx, and serves to protect the vocal folds which are located directly behind it.
Epiglottis
Guards the entrance of the glottis, the opening between the vocal folds. It is normally pointed upward while breathing but when swallowing, elevation of the hyoid bone draws the larynx upward; as a result, this folds down. In this manner it prevents food from going into the trachea and instead directs it to the esophagus, which is posterior.
Frontal Sinus
Mucous-lined airspaces within the bones of the face and skull. Produces mucous.
Nasopharynx
the uppermost part of the pharynx. It extends from the base of the skull to the upper surface of the soft palate.
Pharyngeal Tonsil
(Or adenoids) are a mass of lymphoid tissue situated posterior to the nasal cavity, in the roof of the nasopharynx. Traps irritants from entering into your immune system
Eustachian tube
(also auditory tube or pharyngotympanic tube) is a tube that links the nasopharynx to the middle ear. It is a part of the middle ear.
Oesophagus
an organ in vertebrates which consists of a muscular tube through which food passes from the pharynx to the stomach. During swallowing, food passes from the mouth through the pharynx into the esophagus and travels via peristalsis to the stomach.
Hyoid
Bone situated in the anterior midline of the neck between the chin and the thyroid cartilage
Vocal folds
are composed of twin infoldings of mucous membrane stretched horizontally across the larynx. They vibrate, modulating the flow of air being expelled from the lungs during phonation.
hypoglossal nerve
It controls tongue movements of speech, food manipulation, and swallowing
Trigeminal
Activates the muscles of mastication, the tensor tympani, tensor veli palatini,
tensor veli palatini
muscle in the head that tenses the soft palate.
Levator veli palatini
the elevator muscle of the soft palate in the human body. During swallowing, it contracts, elevating the soft palate to help prevent food from entering the nasopharynx. It is innervated primarily by the pharyngeal branch of the vagus nerve (CN X).
Branches of Trigeminal nerve
Roof: Maxillary branch
Tongue and Floor: Mandibular
Tensor tympani
Its role is to dampen sounds, such as those produced from chewing.
