What is the Supratonsillar fossa?
What is the Supratonsillar fossa?
A slit-like recess extending into the upper part of the palatine tonsil. This fossa is a remnant of the embryological second pharyngeal pouch. Synonym: intratonsillar cleft.
What folds border the tonsillar fossa?
The palatoglossal (anterior pillar) and palatopharyngeal (posterior pillar) mucosal folds diverge from the soft palate to form the boundaries of the tonsillar fossa, which lodges the palatine tonsils.
What are the three types of tonsils?
Size and location. Technically, there are three sets of tonsils in the body: the pharyngeal tonsils, commonly known as adenoids, the palatine tonsils and the lingual tonsils, which are lymphatic tissue on the surface tissue of the base of the tongue, according to Encyclopedia Britannica.
How is Waldeyers ring formed?
Waldeyer’s ring is a collection of lymphoid tissue or follicles in the upper part of digestive system. This ring is formed by: Superiorly- Pharyngeal tonsils or Adenoids.
Is it good to remove tonsils?
For some, the tonsils harbor bacteria that foster chronic infection. “The good news is, having your tonsils removed has proven to significantly reduce the rate of infection for chronic sufferers. And you don’t need your tonsils, so there are no long-term consequences for having them removed,” Dr. Ingley says.
Where are the 5 tonsils located?
The tonsils (palatine tonsils) are a pair of soft tissue masses located at the rear of the throat (pharynx). Each tonsil is composed of tissue similar to lymph nodes, covered by pink mucosa (like on the adjacent mouth lining).
What is Waldeyers ring?
A ring of lymphoid tissue found in the throat. The Waldeyer’s ring is made up of the tonsils, adenoids, and other lymphoid tissue. It contains lymphocytes (a type of immune cell) that help the body fight infection and disease.
What is the supratonsillar fossa of the tonsils?
The lymphoid mass of palatine tonsils does not completely fill the interval between the two arches, so that a small depression, the supratonsillar fossa, exists at the upper part of the interval.
Where is the supraspinous fossa located?
The supraspinous fossa is bounded by the spine of scapula on the inferior side, acromion process on the lateral side and the superior angle of scapula on the superior side. Supraspinatus muscle originates from the supraspinous fossa.
What is the origin of supraspinatus?
Supraspinatus muscle originates from the supraspinous fossa. Distal attachment of the levator scapulae muscle is also on the medial aspect of the fossa. The suprascapular artery and nerve are found within the fossa. The posterior branch of the suprascapular artery supplies the supraspinatous muscle.
How do you expose the supraspinatous fossa?
The fossa can be exposed by the removal of skin and the superficial fascia of the back and the trapezius muscle. The supraspinatous fossa is bounded by the spine of scapula on the inferior side, acromion process on the lateral side and the superior angle of scapula on the superior side.
