skeLetaL systeM ^_^

After all the examinations for the first quarter, here we go again! Back to normal! Lessons..lessons and lessons.

The first lesson for this quarter is about the framework of our body. it is none other than.... the skeletal system.!

Framework and support, these are the well known functions of this system but i learned that it also produces blood cells, provides protection, helps us to breathe, stores minerals and allows movement. well, it's really that important to us.

The primary components of the skeleton are the bones. bones can be classified as long, short, flat and irregular (do i need to say more? i think its self-explanatory). the basic parts of the bone are the epiphysis (bone end), diaphysis (region between the ends), periosteum (connective tissue covering the bone) , medullar cavity (storage for bone marrow) and uhmmm.. are there more? (of course!) well, i cant remember anymore.

There also two types of bone tissues. The compact and spongy. Compact tissues are dense and hard while spongy ones are.. well... like a sponge.. have lots of holes.

We also discussed about bone growth and repair but unfortunately, i already forgot terms about it. c:

While the reporter was discussing, i can't help but feel very very very sleepy! the report should have been better if the reporter made her presentation less wordy and with organizational charts and graphs. c:

we also had an activity! the class was divided into 3 groups to perform a 'skeleton dance' (is that what you call that?). i think we looked as silly as the picture above! hahaha cc: ^^^^
