Animal Structure (Struktur Hewan)
One of the horor lesson
of this semester. In this lesson can study about animal, like all the
system of animal (skeleton, digestive, respiratory, genetalia etc). But
this time I've want to show you about the the skeleton system (sistem
rangka) and little thing about muscle of frog. Enjoy !

Ex. Frog
3. Reptile

Also i will explain about scutes of turtle and the muscle of frog.


Scutes: The
shells are covered with a layer of keratin (the same type of material
that makes up our fingernails or horses' hooves). The keratin is
arranged in patches called scutes, or shields. The carapace usually has 38 scutes, and the plastron, twelve to fourteen.
The names and numbers of the scutes roughly correspond to the adjacent
bones and body portions. The scutes, however, do not precisely overlap
the bones. Instead, they are staggered, which helps give the shell more
rigidity.


Carapace:



Plastron
It;s the muscle of the frog , ventral and dorsal :



So,
can you imagine of this lesson ?It's need very-extremly-hard-work. I
wish I can do the best, not only best score but also best memory of this
lesson in the end of this semester.
