Sharks have no gag reflex.
It's because of a gag reflex--a reflex contraction of the back of the throat, which is caused by touching the soft palate (the soft tissue that makes up the back of the roof of the mouth.) It's what keeps things from coming down our throat except for normal swallowing--it helps prevent choking. Everyone's gag reflex is different.
When you yawn, your body is taking in a big breath of air, which can stimulate the vagus nerve that runs through your throat. This nerve is connected to your gag reflex, so the stimulation can sometimes trigger a gagging sensation.
A reflex is a response to a stimulus that the animal was born with, but a learned behavior is a response to a stimulus that the animal learns or is taught.
differentiate between a dynamic stretch reflex and a static stretch reflex
reflex action is that immediate response to the external stimuli which is provided for the spinal cord itself and not the brain and further the complex action is taken by brain by further thinking upon the matter
No, a somatic reflex are the reflexes of the skeletal muscle movements. The gag reflex is considered to be an autonomic reflex.
Yes, it's quite common to lose your gag reflex. [experience]

Oh, dude, you really wanna know about that? Well, technically speaking, around 10-20% of women are said to lack a gag reflex. But hey, who's counting, right? Just remember, everyone's different, so don't go around testing people's gag reflexes, that's just not cool.
The gag reflex is the body's natural defense mechanism to prevent choking by triggering a contraction in the back of the throat. It can be triggered by various factors such as foreign objects touching the back of the mouth, strong flavors or smells, or even emotional responses like anxiety or stress. Some people may also have a sensitive gag reflex, making them more prone to triggering it.
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.

Yes, the gag reflex is considered an autonomic reflex. It is a protective mechanism that helps prevent choking by triggering the muscles in the throat to contract involuntarily in response to stimuli at the back of the throat.
The gag reflex is often more neurological than physical. Healing can maybe help, but it really has to do with smells and tastes.
