Explanation The four muscles of the eye, which are named according to their placement and function, are the superior rectus, lateral rectus, medial rectus, and inferior rectus muscles. All of these muscles insert into the corresponding surfaces of the eyeball as they are named. The names of these muscles not only indicate the location but also some of the main functions...

Chapter 9.2, Problem 3QC

Summary Introduction

To review:

The four muscles of the eye, whose names themselves describe their actions and locations.

Introduction:

The extrinsic muscles of the eye are six in number. All these six muscles are skeletal muscles, moving each eye. Four of them are named the rectus muscles. They are named so because of their straight-lined placement around the eyeball. The word rectus means straight.

What are biofertilizers and mention the significance

PCBs and River Otters: Otters in Washington State’s Green-Duwamish River have high levels of polychlorinated biphenyls (PCBs) in their livers. PCBs can bind to the estrogen receptors in animals and disrupt the endocrine system of these otters. The PCBs seem to increase the estrogen to androgen ratio, skewing the ratio toward too much estrogen. How would increased estrogen affect the river otter population? Based on your reading of the materials in this unit, what factors can affect fertility in humans? Explain how each of the factors affecting human fertility that you described can disrupt the human endocrine system to affect reproduction.

Other than oil and alcohol, are there other liquids you could compare to water (that are liquid at room temperature)? How is water unique compared to these other liquids? What follow-up experiment would you like to do, and how would you relate it to your life?
