A 62-year-old man has a red, warm, painful lesion on his skin that

extends across his calf from the popliteal fossa to the ankle. This condition

is diagnosed as cellulitis, a bacterial infection of the deeper layers of the

skin. The red colour, increased temperature, and pain of the affected area are

due to an inflammatory response to the infection. In the patient, this

inflammatory reaction is largely caused by the release of pro-inflammatory

substances from the cells of the immune system, which are abundant in the

connective tissue. Which of the following cell types are involved?

A 32-year-old man comes to the physician for

a follow-up examination 1 month after sustaining a chemical

burn over the dorsum of his right hand and forearm. Physical examination shows

hyperextension of the hand at the wrist. The skin over the dorsum of the wrist

is tense and there is a thick, epithelialized scar. The range of motion of

the right wrist is restricted. Which of the following cell types, with their

increased extracellular matrix production, was most likely responsible for this

contracture?

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?

An 18-year-old female patient

is coming to the emergency office of the Department of Ophthalmology. She is

suffering from significant swelling of the upper eyelid. The eyelid is markedly

swollen, stiff and reddened in one spot. The eyelid is painful and causes

significant tearing of the entire eye. After examination of the eyelid, the

doctor concludes that it is a chalazion (eyelid cyst or Meibomian cyst). It is

an inflammation of the Meibomian gland of the eyelid, which can be seen in the

picture. What type of gland is it with regard to the mechanism of secretion?

A 54-year-old man underwent gastroscopy

(endoscopy of the upper digestive tract) for non-specific digestive disorders.

The oesophagus and stomach appear macroscopically fine, but changes are only

visible in the duodenum, where several samples are therefore taken for

histological examination. The final diagnosis is peptic duodenitis,

inflammation of the duodenum, which is a precursor to the development of the

ulcer. This inflammation is usually caused by the

The teacher wants to

demonstrate a typical serous gland to the students in practical exercises

focused on the glandular epithelium. However, he does not have much time to

think about it, because he has more tasks to complete. Which slide should he

choose to show the students typical serous acini?
