The blockage of the eye’s drainage prevents the proper flow of
aqueous humor, which can increase intraocular pressure. In a
healthy eye, aqueous humor flows normally through the drainage
channels, such as the trabecular meshwork and Schlemm’s canal.
Olfactory bulb anatomy: a structure at the base of the brain
that receives signals from the olfactory mucosa via the olfactory
nerve and processes odor information.
Olfactory nerve diagram: the first cranial nerve that carries
signals from the olfactory mucosa to the olfactory bulb, enabling
odor perception and identification.
The cervical nerve branch is the network of nerves
that originates in the spinal cord in the cervical
region of the spine. These nerves are distributed to
the neck, shoulders, and other nearby structures.
The otitis externa of the ear has an altered function in sound
conduction. Moreover, under normal conditions, the ear canal
protects the inner ear. Additionally, it maintains a proper
environment through earwax.
The otitis media with effusion has an altered function in hearing.
Moreover, under normal conditions, the middle ear is air-filled.
Additionally, the Eustachian tube regulates pressure. Furthermore,
it allows proper sound transmission.
Otitismediawith effusion, in this condition, serous fluid accumulates inthe middleear. Thisfluidis notassociatedwith an acute infection. In addition, it usuallyappearsafterrespiratoryinfections. It alsoaffects the ventilationof the ear.
The otitis media with fluid has an altered function in hearing.
Moreover, under normal conditions, the middle ear contains air.
Additionally, the Eustachian tube regulates internal pressure.
Furthermore, it allows proper sound transmission.
Palatine tonsils: lymphoid organs in the oropharynx that
are part of the immune system, filtering bacteria and viruses
and helping protect the body from infections.
Paranasal sinuses in the coronal plane: shows the frontal sinus
in the forehead, its connection to the nasal cavity, and its roles
in voice resonance, skull protection, and air conditioning.

Periodontal disease is a progressive condition affecting the gums and
supporting tissues, starting as gingivitis and potentially leading to
bone loss and tooth mobility if untreated.
