Trismus (TRIZ-mus) describes any restriction to the opening of the mouth caused by trauma, surgery, or radiation associated with the treatment of oral cancer. This condition causes difficulty in speaking and affects the patient's nutrition due to impaired ability to chew and swallow.

At the stage of development when the gut forms there is only a single opening into the digestive track, this opening may become either the mouth or anus. In the echinoderms, chordates, and hemichordates the blastopore becomes the anus and a new opening forms the mouth, these are called deuterostomes
No, the mouth is not classified as a sphincter. A sphincter is a circular muscle that constricts or closes an opening in the body, facilitating control over the passage of substances. While the mouth does have muscles that help control its opening and closing, it primarily functions as an entry point for food and air, rather than acting as a sphincter.
blastopore
A polyp, such as sea anemone, is shaped something like a vase, with the mouth opening at the top.
A hydra typically has only one opening, which is its mouth located at the center of its tentacles. This opening is used for both ingesting food and expelling waste.
Trismus is restruction of the opening of the mouth due to spasm.
The limitation of the gap of the mouth due to trauma, medical procedure, or radiation (oral cancel treatment) is called Trismus. This condition also affects the diet and speech of the patient.
In protostome ("first mouth") the blastopore, or the first opening formed becomes the mouth. In deuterostomes ("second mouth"), the blastopore forms the anus and the mouth develops from a second opening.
An opening through which air or water can flow is a mouth. This can refer to the mouth of a river or a person or animal's mouth.
