So I’ve been studying all day and my back hurts and my bum is pretty much numb. Earlier, I had a brief flare-up of medstudentitis, in which I decided the pain in the back of my calf was a deep-vein thrombus dislodging. Don’t worry, anyone, I’ve had a gin and tonic now so it should be neatly dissolved. [NB: I don’t think that’s actually how it works, so please don’t try that at home]
Most of the time I have trouble finishing things. l quite simply get bored and move to the next topic. This means that much of my non-lecture notes consist of various random facts and hemidiagrams. Today however I managed to actually start and finish summarising the process of healing of wounds in various tissues – skin, bone, muscle, nerves and cartilage.
Some concrete things I learned today: Cartilage heals like a bitch because it is poorly vascularised and therefore it takes ages for the right amount of nutrients and oxygen to get there and help it heal. Muscle heals through action of these little muscle-specific stem-type cells called satellite cells. Bone often heals in such a way as to render the fracture site stronger post-fracture than pre-injury.
All of this made me think about a recent discussion elsewhere in the blogosphere about the healing of wounds. I like the idea that in some things, the healing process makes us stronger than we started out.
