R.O.S

Nowadays, going a bit crazy. Mental stress, physical stress. Suffering from ROS (Reactive Oxidative Stress)! All my red blood cells are bursting slowly I guess, cause I frequently get migraine nowadays. So many things that need to be completed. My goodness! No time for entertainment at all!! This morning, I was looking at the sky and pondering for quite a long time while having my breakfast. Why a student like me need to go through all these, while my friends from other universities are not suffering like what I suffered now? Ermm, I do not know why. All I can do is nag and nag and nag and continue nagging till I complete my degree.

I face a problem remembering all my facts for Anatomy and Physiology. So many scientific names! I've found a way to remember them, but I do not know whether it will works or not. I'll be posting some facts of this subject each time I blog. Hope it can help me remember them easily. Wish me luck!

First post:
muscles+bones+joints=musculoskeletal system
Skeletal system divided into two parts:
1. Axial Skeleton
2. Appendicular Skeleton
Axial Skeleton consist of 80 bones while Appendicular Skeleton consists of 126 bones.
A) Axial skeleton
-lie along longitudinal axis
-at skull, hyoid, vertebrae, ribs, sternum, ear ossicles
B) Appendicular Skeleton
-at upper & lower limbs and pelvic & pectoral girdles.
Hence, all together=206 bones!
There are 5 basic types of bones:
1. long bone (eg. Humerus)
2. short bone (eg. trapezoid, wrist bone)
3. flat bone (eg. Sternum)
4. irregular bone (eg. vertebra)
5. Sesamoid bone (eg. patella)
