What is a carbohydrates? What does it mean? How would you know if you are dealing with carbohydrates? What are the things that compose carbohydrates?
Carbohydrates serve as an immediate source of energy. It is composed of carbon, hydrogen, and Carbohydrates means "sweet carbon". The ending -ose indicates that you are dealing with carbohydrates. The empirical formula of it is: (CH2O)n. There are three groups of carbohydrates: monosaccharides, disaccharides and polysaccharides. Monosaccharide is the major source of fuel for metabolism. It is classified based on the placement of carbonyl group, number of atoms and chiral handedness. Aldose if the carbonyl group is an aldehyde and ketose if the carbonyl group is a ketose. Disaccharide is a two joined monosaccharides. While polysaccharides is equal to ten monosaccharides unit.
This topic was the toughest for me. Whew! I really did not get it all because it was discussed too fast. So maybe I could suggest that it will be better if it will be discussed to us slowly and more examples for us to understand further.

Basic Anatomical Terms (Body Region)
Body region is consists of many terms. Let me share to you some of the things that I know when we have this topic in our class. This was the most interesting so far.
When we say cephalic, it is our head. Orbital is located in the eye area, oral is our mouth, otic is the ear, nasal is our nose and buccal is our cheek. When we go lower from our head, we'll found our neck which is what we call the cervical. Our shoulder is the achromial, axillary for our armpit and in the breastbone area we can found the sternal. the upper arm is called the and brachial and antebrachial for the forearmwhile the depressed area in front of our elbow is what we call the antecubital. For our hand we also have terms for it. For our wrist, it is called carpal, our palm is called palmar and our fingers are called digital. Our knee is what we call the patellar and femoral for our upper thigh. Hmm well there are so many terms in this body region. It really includes many terms. Those are just some of them.
Well I really understand this topic so no need for me to suggest something because it was explained well by Sir Greg.

The Cell Division
Whew! I have to deal with so many terms in this particular topic! Well its kinda enjoying! Here, listen to this.
How does cell divides? How does it reproduce? Here is what I've learned about it.
Cell division includes two (2) process. One is the mitosis and the other is the meiosis. There are different stages in the mitosis. First is the late prophase, here the centrioles of the cell move and its nuclear membrane starts to breakdown. Second is the transition to metaphase where in this stage the nuclear membrane of the cell has totally breakdown and is not visible anymore. The third is the metaphase which means "middle", in this stage the mitotic spindle apparatus has already formed and lies on the poles of the nucleus. The chromosomes are lined up along the cell's equator and are attached to the mitotic spindle via microtubules. Next is the anaphase which means "away". The newly formed chromosomes are pulled along the microtubules toward opposite poles of the cell. After that is the telophase, the chromosome have finished their migration and mitotic structures breakdown, the nuclear membrane forms again and the nucleolus reappears again. Lastly is the interphase or what we call the cytokinesis, the division of cell. Meiosis is also a part of the cell divisions but this one is different from mitosis. Meiosis is a one-way process only and is not engaged in a cycle.
When Sir Greg discussed this one to us, first it was really hard to understand but as we go deeper I fully understand how does this thing divides. Well the way that he taught us about this topic was really great because he had his visual aids which helped more for us to be able to understand the topic, but I think the only problem is that it was discussed to us rappidly so maybe it could have been better if we will take it slow. "Slowly but surely"

Vital Sings and Symptoms
Most of us misunderstood what are vital signs and symptoms. Most of the times we were confused.
What are the differences between vital signs and symptoms? Here is what I have learned.
When we say vital signs, it is common and measurable. It helps us to asses the health of our patients. While when we say symptoms, it is more difficult to measure. It needs further examinations. Here are the examples of vital signs:

We have the heart rate, the blood pressure, the body temperature and the respiratory rate. Those are some of the examples of vital signs. While pain is the example for the symptoms.
I have also learned that syndrome is a specific grouping of signs and symptoms. Also, diagnosis is the identification of a disease determined by studying the patient's signs and symptoms. There is also etiology which is the cause of the disease and prognosis as the prediction of the outcome of a disease.

Anatomy and Physiology
Whew! This was our main topic this last three months. This was really a mind breaking topic! It really consists a lot of things. Well how could it not happen? Anatomy is the study of the structures of the plants, animals or the human body both internal and external. While physiology is the study of the functions of the various structures making up the human body. So tell me, how could it not involved many things if it includes the human body structures and functions? Whew! I really have to do this!!..I am about to do this only day!.because tomorrow is the submission!.I wish everybody could appreciate this blog of mine!!!.here it is!!!learn to love it if you want to survive on this subject!!!!
