Blog update lecture 10

This is the final update to the blog, as this is concerns the final lecture. It was quite an interesting lecture, although it was also sad to realise that this was the last one.

This week was about the control of movement and muscle within the body by the brain. we had learned about how muscles actions work at individual joints. since the muscle contraction mechanism is supported by thick filament gliding theory where muscles get the stimuli at neuromuscular junction. Then we learned about the how spinal control is involved I’m muscular movement. At last we’d deep dived into the brain controlling mechanism of movement. The thing that we find most interesting about this week lecture was  cerebellar loop and basal ganglia loop.

Something I was wondering concerns the spinal cord. In the brain the cell bodies (white matter) is in the centre of the brain, while the extentions (grey matter) is on the outside. This case is reversed in the spinal cord, where the white matter is on the outside and the cell bodies are on the inside. What is the reason for this? Wouldn’t it make more sense that the grey matter is on the outside, since that is the part that branches off into the axons that fire up the muscles? At what point do the grey matter and white matter swap places?
