I. Cell Membrane Structure and Function:
Understanding the cell membrane requires us to look at the personality of fats.
Fats have a glycerol HEAD that is water loving(hydrophilic= hydro (water) and -philic (loving or likes)
Fats also have fatty acid TAILS that are water haters (hydrophobic= hydro (water) and -phobic (hater or fearful)
This molecule is known as a triglyceride because it has three tails.
To understand the personality of fats, let's look at a glass with water and oil. I mean let us REALLY LOOK at the relationship that is going on BETWEEN the oil and water.
Pretend to place some 'special' glasses over your eyes that would give you superior vision and allow you to see the molecules.
Do you see how the fats stand on their 'heads' so that the hydrophilic heads can be next to the water (which is also hydrophilic...think about it...water loves itself!)?
Do you see how the hydrophobic tails move away from the water?
Do you see how the hydrophobic tails line up together and the hydrophilic heads line up together? Likes attract Likes!

Medial vs. Lateral:
Medial refers to a location or movement towards the
midline of the body. Lateral refers to a location or
movement away from the midline. A lot of times, these
two are in relationship to one another. I.e. The
bellybutton is medial to the hip.
Activity to learn these terms:
1) Place your arms straight out in front of you and
place your palms together. If we were to fold
your body in half, you would end up with a right
and a left half mirror image of each side of the
body. The fold down the middle is known as the
Mid-Sagittal plane or the midline.
2) Holding you palms together out in front, slowly
move your hands away from the midline.
Moving away from the midline is known as
3) Now, move your hands towards each other.
Moving your hands towards the midline is
known as Medial.
4) Repeat this process of lateral and medial
movement with your hands (let your palms hit).
As you move think away is Lateral and towards
5) Continue this movement and get faster and
faster! Yea! You got it! Way to give your self
a hand! (Yes…clapping is a lateral and medial
movement). Just having fun with you!
