The pharyngeal raphe is a raphe that serves as the origin and insertion for several of the pharyngeal constrictors (thyropharyngeal part of the inferior pharyngeal constrictor muscle, middle pharyngeal constrictor muscle, superior pharyngeal constrictor muscle).

Consequently, what are the pharyngeal constrictors?

The middle pharyngeal constrictor is a fan-shaped muscle located in the neck. It is one of three pharyngeal constrictors. Similarly to the superior and inferior pharyngeal constrictor muscles, the middle pharyngeal constrictor is innervated by a branch of the vagus nerve through the pharyngeal plexus.

One may also ask, what attaches Pterygomandibular raphe? Its medial surface is covered by the mucous membrane of the mouth. Its lateral surface is separated from the ramus of the mandible by a quantity of adipose tissue. Its posterior border gives attachment to the superior pharyngeal constrictor muscle. Its anterior border attaches to the posterior edge of the buccinator.

Simply so, what makes up the pharyngeal plexus?

The pharyngeal plexus, which mainly overlies the middle pharyngeal constrictor, is formed by: Pharyngeal branches from the glossopharyngeal nerve (CN IX). Pharyngeal branch of the vagus nerve (CN X). Branches from the external laryngeal nerve.

What does the superior pharyngeal constrictor do?

The superior pharyngeal constrictor muscle is one of the pharyngeal constrictor muscles. Its primary action is constriction of the pharynx (in coordination with the middle pharyngeal constrictor and the inferior pharyngeal constrictor muscles) to deliver a bolus of food into the esophagus.

Is the pharynx an organ?

Organs of the Respiratory System These organs are shown in Figure below. In addition to the lungs, these organs include the pharynx, larynx, trachea and bronchi. The nasal cavity is also part of the respiratory system. The pharynx is a long tube that is shared with the digestive system.

What is the pharyngeal?

The pharynx (plural: pharynges) is the part of the throat behind the mouth and nasal cavity, and above the esophagus and larynx – the tubes going down to the stomach and the lungs. It is found in vertebrates and invertebrates, though its structure varies across species.

What is the function of the epiglottis?

The epiglottis is a leaf-shaped flap of cartilage located behind the tongue, at the top of the larynx, or voice box. The main function of the epiglottis is to seal off the windpipe during eating, so that food is not accidentally inhaled.

Where is the nasopharynx located?

The nasopharynx is 2 to 3 cm wide and 3 to 4 cm long and situated behind the nasal fossa inside the occipital bone. The nasopharynx is the space above the soft palate at the back of the nose and connects the nose to the mouth, which allows a person to breathe through the nose.

Is the esophagus on the right or left?

Esophagus is located at left of midline at level of 1st dorsal vertebra, right of midline at level of 6th dorsal vertebra, and left of midline again at level of 10th dorsal vertebra.

Where is the Laryngopharynx located?

Laryngopharynx. The laryngopharynx is where both food and air pass. It can be found between the hyoid bone and the larynx and esophagus, which helps guide food and air where to go. It is a part of the pharynx.

What are the 3 parts of pharynx?

The pharynx is the part of the digestive system situated posterior to the nasal and oral cavities and posterior to the larynx. It is therefore divisible into nasal, oral, and laryngeal parts: the (1) nasopharynx, (2) oropharynx, and (3) laryngopharynx.

Where is the larynx located?

Larynx: A tube-shaped organ in the neck that contains the vocal cords. The larynx is about 5 cm (2 in.) long. It is part of the respiratory system and is located between the pharynx and the trachea.

Is the pharynx the throat?

The throat (pharynx) is a muscular tube that runs from the back of your nose down into your neck. It contains three sections: the nasopharynx, oropharynx and laryngopharynx, which is also called the hypopharynx.

What is the structure of the larynx?

Larynx. 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 are the larynx?

The larynx, which includes your vocal cords, is another name for the voice box. It's a tube about 2 inches (5cm) long in adults. It sits above the windpipe (trachea) in the neck and in front of the food pipe. The food pipe in the upper part of the neck is called the pharynx. protects your windpipe during swallowing.

How long is the pharynx?

Pharynx is 12–14 cm in its vertical length and extends from the base of skull to the upper border of upper esophageal sphincter (UES) [14].

Where does the nasopharynx begin and end?

However, in general, in both rodents and humans the nasopharynx is located beneath the base of the skull and dorsal to the soft palate, the oropharynx lies between the end of the soft palate and tip of the epiglottis, and the laryngopharynx extends from the tip of the epiglottis posterior to the beginning of the

What is the pharynx made of?

The pharynx comprises the caudal aspects of the oral and nasal cavities at the confluence of the digestive and respiratory tracts. The pharynx is a short fibromuscular tube divided into three compartments: the oropharynx, the nasopharynx and the laryngopharynx (Fig. 51-1).

What does the pharyngeal nerve innervate?

Pharynx

Where is the Pterygomandibular raphe located?

Anatomical terminology The pterygomandibular space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space in the head and is paired on each side. It is located between the medial pterygoid muscle and the medial surface of the ramus of the mandible.

Where is the Mylohyoid line?

The mylohyoid line is a line on the inside of the mandible. It extends superior and posterior (upward and backward) on either side from the lower part of the symphysis of the mandible. The mylohyoid line is at the body while the mylohyoid groove is at the ramus.
