Mucormycosis, also known as black fungus, [3][4] is a severe fungal infection [11] that comes under fulminant fungal sinusitis, [12] usually in people who are immunocompromised. [9][13] It is curable only when diagnosed early. [12] Symptoms depend on where in the body the infection occurs. [14][15] It most commonly infects the nose, sinuses ...
Layers of the Alimentary Canal.The wall of the alimentary canal has four basic tissue layers: the mucosa, submucosa, muscularis, and serosa. The enteric nervous system in humans consists of some 500 million neurons [11] (including the various types of Dogiel cells), [1] [12] 0.5% of the number of neurons in the brain, five times as many as the one hundred million neurons in the human spinal ...
Mucus is made up of a fluid component of around 95% water, the mucin secretions from the goblet cells, and the submucosal glands (2–3% glycoproteins), proteoglycans (0.1–0.5%), lipids (0.3–0.5%), proteins, and DNA. [7] The major mucins secreted – MUC5AC and MUC5B - are large polymers that give the mucus its rheologic or viscoelastic ...
Catarrh. Catarrh (/ kəˈtɑːr / kə-TAR) is an inflammation of mucous membranes in one of the airways or cavities of the body, [1][2] usually with reference to the throat and paranasal sinuses. It can result in a thick exudate of mucus and white blood cells caused by the swelling of the mucous membranes in the head in response to an infection.
Ethmoid sinus. Coronal section of nasal cavities. The ethmoid sinuses or ethmoid air cells of the ethmoid bone are one of the four paired paranasal sinuses. [1] Unlike the other three pairs of paranasal sinuses which consist of one or two large cavities, the ethmoidal sinuses entail a number of small air-filled cavities ("air cells"). [2]
Abnormal concentrations of serotonin have been associated with IBS, predominantly increased concentrations intensifying gastrointestinal motility and mucosal secretions from the gut mucosa. Severe IBS often manifests as either chronic constipation or chronic diarrhoea, and abnormal EC cell populations have been correlated with both conditions.
7.7 million (2019) [9] Deaths. 236,000 (2019) [9] Meningitis is acute or chronic inflammation of the protective membranes covering the brain and spinal cord, collectively called the meninges. [10] The most common symptoms are fever, intense headache, vomiting and neck stiffness and occasionally photophobia. [1]
Sinusitis, also known as rhinosinusitis, is an inflammation of the mucous membranes that line the sinuses resulting in symptoms that may include production of thick nasal mucus, nasal congestion, facial congestion, facial pain, facial pressure, loss of smell, or fever. [6][7] Sinusitis a condition that affects both children and adults.
