The advanced periodontal stage is a severe form of periodontitis
with extensive bone loss, gum recession, and tooth mobility,
often leading to tooth loss and requiring advanced treatment.
The advanced serous otitis media has an altered function in
hearing. Moreover, under normal conditions, the middle ear is
air-filled. Additionally, the Eustachian tube regulates pressure.
Furthermore, it impairs sound transmission.
Affected mammary lobe. It represents glandular tissue with
carcinoma, showing abnormal cell proliferation, alteration
structural and compromise of mammary function, with possible
tumor progression.
Airborne transmission occurs when infectious particles are
transmitted through the air. Preventive measures are essential.
to reduce its spread. The use of masks protects and reduces
the spread of respiratory infections.
The allergic fungal sinusitis has an altered function in sinus
ventilation. Moreover, under normal conditions, these cavities
are air-filled. Additionally, mucus flows properly into the
nasal cavity.
Alteration of aqueous humor drainage in an eye with glaucoma. It
shows how a blockage in the trabecular meshwork or in Schlemm’s
canal prevents proper fluid flow, causing an increase in intraocular
pressure.
Altered bronchial mucosa. It represents the increase in secretion
of mucus by goblet cells and bronchial inflammation, causing
airflow obstruction, persistent cough, and respiratory difficulty,
typical in bronchitis.
Altered mucous cells. They represent the hyperactivity of the
goblet cells with excessive production of thick mucus, which
which causes obstruction of the airways, persistent cough
and respiratory difficulty in bronchitis.
Alveolar mucus. It represents the excessive and thick accumulation
of mucus in the respiratory epithelium, caused by inflammation, which
hinders airflow and causes persistent cough and respiratory problems.
Infectious alveolar pneumonia is an inflammation of the alveoli.
caused by microorganisms. It causes fluid accumulation, hindering
gas exchange and generating respiratory symptoms.
The neuronal degeneration in Alzheimer’s disease has an altered
function in the nervous system. Moreover, under normal conditions,
neurons communicate efficiently. Additionally, they support memory
consolidation.
Amyotrophiclateralsclerosisisa progressivedegenerationof motorneurons. These neuronsare locatedinthe motor cortex andthe spinalcord. In addition, its deteriorationinterruptsthe signal transmission.
