The medial margins of the frontalis muscles are joined together for some distance above the root of the nose; but between the occipitales there is a considerable, though variable, interval, occupied by the galea aponeurotica. Function. In humans, the frontalis muscle only serves for facial expressions.
Olfactory receptors ( ORs ), also known as odorant receptors, are chemoreceptors expressed in the cell membranes of olfactory receptor neurons and are responsible for the detection of odorants (for example, compounds that have an odor) which give rise to the sense of smell. Activated olfactory receptors trigger nerve impulses which transmit ...
The skull is a bone protective cavity for the brain. [1] The skull is composed of four types of bone i.e., cranial bones, facial bones, ear ossicles and hyoid bone, however two parts are more prominent: the cranium ( pl.: craniums or crania) and the mandible. [2] In humans, these two parts are the neurocranium (braincase) and the viscerocranium ...

Like in humans, it functions to prevent entry of food into the trachea during swallowing. The position of the larynx is flat in mice and other rodents, as well as rabbits. [4] For this reason, because the epiglottis is located behind the soft palate in rabbits, they are obligate nose breathers, [18] [19] as are mice and other rodents. [4]
Danger triangle of the face. The danger triangle of the face consists of the area from the corners of the mouth to the bridge of the nose, including the nose and maxilla. [1] [2] : 345–346 Due to the special nature of the blood supply to the human nose and surrounding area, it is possible for retrograde infection from the nasal area to spread ...
