Re: Anatomy B/C Question Marathon
Yay!
Ur right about the psoriasis. Thanks for giving it to me
This question comes in two parts and requires three answers.
Which two layers of the epidermis are used in the synthesis of vitamin D3, and where does the energy required come from?

Looking forward to anatomy, protein, fossils, and optics (NYS trial) this year!

stratum basale and stratum spinosum; ultraviolet rays found in sunlight?

I was trying to let someone else go, but it's been long enough so I will.
Evolutionarily, they have different functions. Your head hair protects you from sunburn while eyebrows just protect your eyes from dust.
Anatomically, eyebrow hairs have a shorter growing phase than head hair

The hair on our scalp has an anagen stage of 2-7 years depending on the individual's diet, age, and health in general. Other parts of our bodies (eyebrows, lashes, underarms etc) have a shorter anagen stage. For example, eyebrows are around 4 months.

Re: Anatomy B/C Question Marathon
Sorry, my textbook doesn't go very into depth about hair, I actually think the writer had something against the integumentary system in general.
Which structures form the elaborate patterns in thick skin, and what is the purpose of those structures?

Also, Whoppers, can you tell us what your source was for that?
Epidermal ridges, which are formed when the epidermis projects down into the spaces between the dermal papillae during fetal development. The ridges increase the surface area of the epidermis and allow a firmer grip in the thick skin areas, i.e. the fingertips, palms, & soles

Re: Anatomy B/C Question Marathon
The book is Essentials of Anatomy & Physiology. I don't have it with me at the moment and don't know the author offhand.
You are correct. For the second part, you are also correct, but the answer I was looking for was that the epidermal ridges help get nutrients into the epidermis because the epidermis doesn't have it's own blood vessels.
Your turn

There are tons of authors who have written a book with that title...>_>fantasyfan wrote:The book is Essentials of Anatomy & Physiology. I don't have it with me at the moment and don't know the author offhand.

Um...I think that's kinda debatable...I suppose that works, but even then, dermal papillae exist throughout your skin, right? Epidermal ridges don't, they exist in certain parts of the skin. I imagine the density of the blood vessels in the papillary region is the primary source of its nutrients...but then again, I suppose thick skin could use the extra help in getting the nutrients that way, since it's thicker than thin skin.
Whatever, that was the most obvious answer to me
Anyway, next question (I'm bringing this back to the nervous system ): describe the anatomical differences between the sympathetic and parasympathetic divisions of the autonomic nervous system in terms of motor output, the location of ganglia, and differences in the preganglionic & postganglionic fibers of both divisions
