### What cranial nerve allows you to smile?

Smiling is an action produce by more than one muscle but the
nerve that allows you to do that is the facial nerve (7th cranial
nerve). Facial nerve has 5 branches and the action of all 5 allows
you to smile nicely. The temporal branch allow you to wrinkle your
forehead, the zygomatic branch allows you to partially close your
eyes, the buccal branch allow you to elevate your chin, and the
marginal mandibular allow you to widen your mouth laterally.

There are more than 3 nerves in the cervical plexus. The most
important nerve here is the phrenic nerve, which supplies the
diaphragm, from roots C3-5. Other deep branches include the ansa
cervicalis and segmental branches; the superficial branches are the
lesser occipital, great auricular, transverse cervical and
supraclavicular.

### What is the Factor tree for 90?

a factor is actually like a tree with branches.
just divide 90 by prime whole numbers until you get all prime
numbers.
first divide 90 by 2
90/2 = 45 [2 is a prime whole number]
45/5 = 9 [5 is a prime whole number]
9/3 = 3 [3 is a prime whole number]
since your last number is 3 you cant divide anymore to get a
smaller prime whole number.
so now use the numbers you have... 90,45,9,2,3,3, and 5 to make
your factor tree.
start with 90 at top. make two branches with 45 and 2 on the
ends. make two more branches from 45 with 9 and 2 on the ends. make
two more branches from the 9 with a 3 and 3 on the ends. all of the
ends of your branches now have prime whole numbers and you are
finish!
90
45,2
15,3,2
5,3,3,2

###### Asked in Factoring and Multiples

### What are the factors for 75?

to find the answer, you should make a factor "tree". Draw it as
I explain it. 75 "branches" down to 5 & 15 (because 5 x 15=75)
5 will not "branch" any lower (because the only # you can divide it
by is 1 or 5) 15 branches down to 5 & 3 at the bottom of your
"branches" you will have two 5's and one 3. The factors for 75 are
1, 3, 5 & 75. (#1 and the number in question will always be
factors, in addition to the numbers at the bottom of your factor
tree) Prime factorization can be written as 3x5x5 or 3x5 squared.
Hope that helps.
