9. Bone
One of the structures composing the
skeleton of a vertebrate. The hard
connective tissue forming the
substance of the skeleton of most
vertebrates, composed of a collagen-
rich organic matrix impregnated with
calcium, phosphate, and other
minerals
10. Hyaline Cartilage
Hyaline cartilage is a type of body tissue,
also called gristle. It is shiny, slippery, firm,
translucent, and bluish-gray in color. Hyaline
cartilage is simple in structure, with no nerves or
blood vessels. It has high elasticity and helps
cushion and protect bones. The word hyaline
comes from the Greek for glassy, and refers to the
translucence of the tissue.
11. Fibrocartilage
Fibrocartilage is a type of cartilage which is very
rich in type I collagen, and found in areas such as
the meniscus of the knee, the pubic symphysis,
and the vertebral discs. This type of cartilage is
especially strong and durable, so it appears in
areas where these traits are needed.
12. Elastic Cartilage
Elastic cartilage is histologically similar to hyaline
cartilage but contains many yellow elastic fibers
lying in a solid matrix. These fibers form bundles
that appear dark under a microscope. These fibers
give elastic cartilage great flexibility so that it is
able to withstand repeated bending
13. Blood
Blood is a specialized bodily fluid in animals that
delivers necessary substances such as nutrients
and oxygen to the cells and transports metabolic
waste products away from those same cells.
