A
48-year-old woman presents with blisters on her trunk that have been there for 3 days. The blisters are large, turbid, and flaccid, and are located within the superficial epidermis. She

A 4-year-old boy has recently returned from a holiday abroad and has now arrived now at the Clinic of Infectious Diseases with his parents due to severe dehydration caused by diarrhoea. The causative bacterium is , which disrupts the structure of one type of intercellular junctions – tight junction = zonula occludens. This physiologically prevents the passage of fluid between cells – the so-called paracellular route. Disruption of these tight junctions results in fluid loss into the lumen of the gastrointestinal tract. Where can we find these tight junctions on cells?
Arrhythmia, i. e. irregularity of the heart rhythm, can be caused, for example, by a high or low level of certain ions. Heart muscle cells (cardiomyocytes) can exchange these ions with each other to maintain homeostasis. Cardiomyocytes are connected by intercalated discs. What type of intercellular junction is part of the intercalated discs and used for ion exchange?
A 19-year-old student comes to the eye clinic with a very common problem today. He suffers from cutting and burning eyes, the feeling of a foreign body in the eye, pressure, and the feeling of tired eyes. The eyes are red. He is diagnosed with dry eye syndrome. This can have many causes, and one of them is low tear production, for example, as a result of taking certain medications. Tears are produced by the lacrimal gland. The lacrimal gland is an exocrine gland. Its cells have a basophilic cytoplasm and a round nucleus located in the basal third of the cell. The basal part of the cells shows significant basophilia due to the accumulation of polyribosomes and granular endoplasmic reticulum for the production of proteins that are part of the produced secretion. The cells contain zymogen granules, which are mostly released in a merocrine manner. What type of gland is a lacrimal gland?
