Histo credit test


I made it! I got my very first credit in histology. The question was thymus in involution, not the easiest slide. I got the mark "2-very good". Happy!!
The test is like this: we are all gathered in the histolab. We have all our books, notes and microscopes and slideboxes aviable. Then one by one get up to the front, where the teacher give you a single slide, a paper for notes and a microscope. You are not allowed to bring anyting but a pencil. Then you look at the slide macroscopically, and in the microscope.
The task is to identify this nice, pinkstained piece of tissue, and tell as much as possible about it. Then the professor ask a lot of questions. Then you answer, hopefully a bit more than what he/she asked for. And then you get your mark.


Just for your information. Thymus is sitting in your anterior/superior mediastinum. It's a place where t-lymphocytes matures (or get killed by apoptosis after negative and positive selection). There is a lot of adipose tissue in the thymus in involution. And there is someting called Hassal's corpuscles in the cortex.
And if you don't understand it at all, it's ok. I hardly understand it myself.. It's just this way it is!
