♥This week in our biology class, we didn't have any new lesson. We just have quizzes for the topic that we have discussed a week ago, like the Nervous system. We used the responder for the quiz. We enjoyed every quizzes because of the responder, we didn't feel any nervous, only excitement! All of us passed and got high score in the quiz except for Conrad :). This week also, there's a lot of shorten period that's why we haven't use our time wisely in our class. its only limited for 40 minutes. The reason why we have that limited time is because everybody needs to prepare for the upcoming event, the United Nations' Bazaar. ♥
♥That's all I can share for this week, :) ♥

♥October 12 - October 16♥
♥This week, I have learned about the "Nervous System."♥
♥Nervous system is divided into two , Central Nervous System(CNS) and the Peripheral Nervous System(PNS). The CNS refers to the brain and the spinal cord while the PNS refers everything outside the brain and spinal cord. PNS is also divided into two, the Somatic or voluntary and the Autonomic. Autonomic is also divided into two, parasympathetic and sympathetic branch. Neuroglia and Neurons are in the part of Nervous tissue, neuroglia are specialized cells that allows nervous system to perform an action while the neurons is the group of cells which carries the control function of the nervous system. I also knew that the spinal cord as 31 segments, each with a pair of spinal nerves, The spinal nerves are parts of the peripheral nervous system.♥
♥My suggestion for this lesson is don't take this lesson very fast, I mean we need to focus on this section, its not just easy to understand. Please explain very well especially the reporter didn't explain well the whole topic. I hardly understand.♥

♥This week, we have discussed about the integumentary system (reported by me :D) ♥
As part of my report, i gave them the functions of the integumentary system...well, integumentary system protects our body from invasion of disease caused by pathogens,helps the body from drying out,acts as a storage for fats, also skin provides vit. D and helps to regulate body temperature.
♥skin has its three layers : Epidermis is the first layer of the skin it has no blood vessels and is made up of smaller stratified squamous epithelium, Dermis is the second, which is more thick and denser, and Subcutaneous fascia the last layer of the skin... composed of fatty tissues and of course fats. ♥
♥Hair and nails are also part of my report in integumentary system. Nails are specialized epithelial cells originating from the nail root. Cuticle, nail body, lunula are some of its parts while the hair, it helps to regulate body temperature it also protects our sensory organs...♥
♥Burns (ouch) burns has four distinct degrees...1st degree burn damages only the epidermis, 2nd degree burn affects the whole epidermis and a portion of dermis, while 3rd degree burn damages the three layers of skin completely...4th degree burn is a kind of burn that penetrates to the bone!!!♥
♥ I also discussed the diseases with my power point presentation...the next day, they had a quiz (I'm the reporter so i don't have to take the quiz) ...this week also, we had a check up quiz for integumentary (different from the first quiz)♥
