1.

a)The outer portion of the skin, formed by epithelial tissue which rests on the dermis

b)Dense irregular connective tissue that forms the deep layer of the skin

c)Loose connective tissue underneath the dermis which connects the dermis to muscle or bone.

d)The process of manufacturing blood cells

e)Dense bone matrix enclosing only a few spaces

f)Bone with many small spaces or cavities surrounding the bone matrix

g)Bone formation

h)Hyaline casrtilage that covers the ends of a bone joint

i)The portion of the skeleton that supports and protects the head, neck and trunk. (trunk? lol)

j)The portion of the skeleton that attaches to the axial skeleton and has the limbs attached to it.

k)A junction between flat bones of the skull

l)A projection on a bone

m)A passageway

n)A hole

o)A hollowed out space in a bone

2.
a) The two layers of cells are the epidermis and the dermis.
b) The epidermis contains keratinized cells
c) The dermis contains papillaries.

3.
The dermal papillae help the epidermis because the draw blood vessels up closer to the epidermis that they would normally if there were no papillae there.

4.
Cuts heal differntly on different places of the body because they are on different cleavage lines. If a cut is parallel to a cleavage line then it will probably heal quicker and have less scarring than a cut perpendicular to the cleavage line.

5.
The hair follicle helps heal burns because it completes mitosis rather quickly.

6.
I don't understand the questions.

7.
Sebaceous glands are the glands that produce the hair follicle.

8.
The purpose of sweat glands are to release sweat, therefore cooling the body.

e)Stratumcorneum

10.
Stratum basale and startum spinosum are the layers in which cells are still alive.

12.
a)nerves
b)hairs
c)sweat pore
d)blood vessels
e)sweat duct
f)sweat gland

o)Epidermis

13.
a)Medulla,Cortex,cuticle
b)cortex
c)medulla;cuticle

14.
The hair matrix is composed of undifferentiated cells.

15.
