Describe the difference between the aqueous and vitreous humor
Aqueous Humor - water-like fluid housed in the anterior segment of the eye (supports the lens)
Vitreous Humor - gel-like substance housed in the posterior segment of the eye

Where is fat stored in the long bone?
Yellow marrow
200
Striated involuntary muscle tissue is classified as ________ muscle.
Cardiac muscle

What are the divisions and subdivisions of the nervous system?

Explain how the function of rods and cones differ.
Rods and cones are photoreceptor cells because they respond to light. Rods allow us to see gray tones in dim light, and they provide our peripheral vision. By contrast, cones allow us to see color under bright light conditions. Three varieties of cones are sensitive to particular wavelengths of visible light.
