What is the buccopharyngeal fascia?
The buccopharyngeal fascia forms a distinct layer just up to the posterior part of the buccinator muscle and envelops the superior pharyngeal constrictor muscle. Its position permits it to connect and modulate the action of the mouth with that of the pharynx.
Where is the buccopharyngeal fascia?
The posterior segment of this fascia, spanning between each carotid sheath, running behind the esophagus and the posterior portion of the lateral lobes of the thyroid gland, is referred to as the buccopharyngeal fascia.
Is buccopharyngeal fascia pierced by parotid duct?
Gross anatomy The parotid duct passes anteriorly through the buccal fat superficial to the masseter muscle and over its anterior border, then through the buccopharyngeal fascia and the buccinator muscle.
What is buccopharyngeal?
Relating to the cheek or mouth and the pharynx.
What is buccopharyngeal respiration?
Buccopharyngeal respiration is the mode of respiration via the buccopharyngeal cavity or the mouth. In this mode, the oxygen is taken up simply by diffusion or by the contraction and relaxation of the muscles of the buccopharyngeal cavity.
What does buccopharyngeal mean?
adj. Relating to the cheek or mouth and the pharynx.
What is buccopharyngeal cavity?
In anatomy, buccopharyngeal structures are those pertaining to the cheek and the pharynx or to the mouth and the pharynx.
What is Buccopharyngeal?
What is fascia made of?
Fasciae are similar to ligaments and tendons as they are all made of collagen except that ligaments join one bone to another bone, tendons join muscle to bone and fasciae surround muscles or other structures. The video below gives a fascinating introduction to fascia.
What is the only space the retropharyngeal space communicates with?
The retropharyngeal space is posterior to the pharynx and esophagus, and extends from the base of the skull to the thoracocervical junction as the alar fascia attaches to the buccopharyngeal fascia (at a variable level between the C6 and T6 vertebral bodies) 2.
Why is it called danger space?
The danger space or alar space, is a region of the neck. The common name originates from the risk that an infection in this space can spread directly to the thorax, and, due to being a space continuous on the left and right, can furthermore allow infection to spread easily to either side.
What is the buccopharyngeal membrane?
The buccopharyngeal membrane (Latin, bucca = cheek) or oral membrane, forms the external upper membrane limit (cranial end) of the early gastrointestinal tract (GIT). This membrane region first develops in the trilaminar embryo (week 3) during gastrulation and lies above the cranial end of the notochord.
What is Stage 11 buccopharyngeal membrane?
Human Embryo Stage 11 buccopharyngeal membrane. Buccopharyngeal membrane – degenerating. Buccopharyngeal membrane position relative to adult anatomy. The buccopharyngeal membrane (Latin, bucca = cheek) or oral membrane, forms the external upper membrane limit (cranial end) of the early gastrointestinal tract (GIT).
What happens when the buccopharyngeal membrane ruptures?
In humans, persistence of the buccopharyngeal membrane can lead to orofacial defects such as choanal atresia, oral synechiaes, and cleft palate. Little is known about the causes of a persistent buccopharyngeal membrane and, importantly, how this structure ruptures.
What does the buccopharyngeal fascia connect to?
Parallel to the carotid sheath and along its medial aspect the pretracheal fascia gives off a thin lamina, the buccopharyngeal fascia, which closely invests the constrictor muscles of the pharynx and is continued forward from the constrictor pharyngis superior onto the buccinator.
