A 54-year-old woman presents with numbness and

weakness in her lower extremity as well as pain that radiates from her lower

back down the back of the thigh. Imaging reveals that the patient has a

herniated intervertebral disk. This occurs when the softer center of the disk,

the nucleus pulposus, herniates out of the stronger outer portion, the annulus

fibrosus. What is typical for the tissue forming the annulus fibrosus?

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 46-year-old woman fell on ice in winter and

broke her tibia. After an X-ray examination, it was decided to cast the limb.

After 2 weeks she presented for a check-up and tightening of the cast; after 8

weeks the cast was removed. During the healing process of the bone fracture, a

blood clot first appears filling the fracture. The clot is remodelled into a

non-specific granulation tissue. This tissue then forms a connective callus. In

the temporary connective tissue, both the fibrocartilage and hyaline cartilage

differentiate. The connective tissue and cartilage are subsequently replaced by

bone. Which type of bone tissue appears first during the healing process?
