The 69-year-old man's condition has deteriorated

greatly in the last few days. He feels very tired, faint, and weak. For the

third day, he still has a fever that is not responding to medication, but he

has no other symptoms of infection. He has developed small petechiae (spotty

bleeding) on his limbs and has had epistaxis (nosebleeds) several times. He is

now coming to the doctor because these symptoms are compounded by shortness of

breath and non-specific neurological symptoms. The GP immediately sends the

patient to the hospital, where the results of the blood count suggest a lot

about the patient's diagnosis. The patient has anaemia, thrombocytopenia and

leukopenia, but immature forms of white blood cells, called blasts, are present

in the blood. It is very likely that this patient has some form of acute

leukaemia. However, red bone marrow sampling is necessary to confirm and

establish a specific diagnosis. In which bones in adulthood does red bone marrow

remain and is it therefore possible to perform the necessary sampling from

them?

A 33-year-old man visits a general

practitioner's office complaining of loss of smell, frequent nosebleeds,

difficulty swallowing, and hoarseness. During the interview he admits to

cocaine use since his college days. Subsequent examination in the ENT clinic,

to which the patient is referred, reveals the presence of severe inflammation

of the nasal mucosa and a disrupted cartilage structure in the nasal septum.

What type of collagen predominates in this type of cartilage?

Rewrite the underlined part of the sentence so

Achondroplasia is an

autosomal dominant disease that leads to a disorder of endochondral

ossification. A typical picture is a disproportionate growth disorder. However,

the trunk is almost normal length, the limbs are very short. Another feature is

a brachycephalic skull (pear-shaped), a broad forehead, and supraorbital

arches. Which type of cartilage is the model for the newly formed bone?
