Is the tongue involved in the swallowing reflex?
The tongue is involved in the swallowing reflex insofar as it raises voluntarily to force food backward toward the pharnyx, where reflex action takes over in which the larynx is closed by the epiglottis and the nasal passages are closed by the soft palate so that food does not enter into the trachea. Food then moves down the esophagus by peristalsis and gravity.
Is swallowing a reflex or instinct?
Swallowing is a reflex.
Which bone supports the larynx superiorly?
The hyoid bone supports the larynx superiorly. It is a U-shaped bone located in the neck and serves as a point of attachment for muscles involved in swallowing and speech.
What is the effector in a gag reflex?
The effector in a gag reflex is the contraction of muscles involved in swallowing, including the pharyngeal muscles in the throat. These muscle contractions help to expel any foreign objects that stimulate the back of the throat, triggering the gag reflex.
Why it is difficult to swallow saliva in rapid succesion?
It may be difficult to swallow saliva rapidly because the body has a reflex called the swallowing reflex, which can't occur too frequently in quick succession. This reflex helps prevent choking by coordinating the muscles involved in swallowing. Trying to swallow rapidly may disrupt this coordination and make it more challenging to swallow.

How the larynx works in the throat while swallowing?
The larynx is located at the top of the trachea or windpipe. In the larynx, the vocal folds, commonly known as the vocal cords, close tightly when swallowing to prevent any food or drink from entering the trachea and lungs.
What does the central nervous system have to do with swallowing?

Food is forced into the digestive tract by the?
By the swallowing reflex.
What is the flap the closes off the larynx and prevents food and water from entering the larynx during swallowing?

This flap at the base of the tongue protects the larynx while swallowing?
glottis
