-----------------------

The outer layer of the skin is called the _(1)_ and it is composed of two layers. The top layer where mitosis no longer occurs is made up of _(2)_ cells. The second layer where mitosis occurs is called the _(3)_ layer. The basal layer has two important proteins _(4)_ & _(5)_ made by specialized cells. The second layer of skin is called the_(6)_. In this layer you can find _(7)_ that help maintain a constant body temperature. When they contract heat is _(8)_ and when they dilate heat is_(9)_. Also in this layer you can find _(10)_ that consists of dead cells filled with _(11)_ (a protein). These things go through _(12)_ in order to grow. _(13)_ also goes through mitosis to grow and helps _(14)_ fingertips and toetips. _(15)_ help detect pain and heat in the skin. The last layer is called the _(16)_ that stores _(17)_.

a. Collagen

b. Elastin

c. Keratin

d. Melanin

e. Oil gland

f. Sweat gland

g.

The outer layer of the bone is called the _(24)_ that has nerves and blood vessels that pass through it to the next layer called the _(25)_ bone. The next layer is called _(26)_ bone where red & yellow marrow is found. Red marrow makes _(27)_. Yellow marrow stores _(28)_. Embryos are made up entirely of _(29)_, replacing this with bone requires _(30)_.

a. Appendicular

b. Axial

c. Bone marrow

d. Compact bone

e. Osteocyte

f. Periosteum

g. Spongy bone

h. Synovial Fluid

a. Ball & socket

b. Hinge

c. Pivot

d.

60.______________

The contraction of muscles requires _(61)_ ; because of this muscles are constantly carrying out _(62)_. Muscle bulk is caused by _(63)_ , not an increase in muscle fibers. A person’s strength is determined by the _(64)_.

Connective tissue called _(65)_ attaches skeletal muscles to bone.

a. Actin & myosin

b. Extensor

c. Flexor

d. Insertion

e. Origin

f. Sacromeres

a. Antibody

b. Antigen

c. B cells

d. Disease

e. Infectious Disease

f. Pathogen

g. Phagocyte

h. Vaccine
