Cartilage 
Cells are located in lacunae (holes) in a matrix.
Read the descriptions of the different types of cartilage below
and select the best choice using all the clues you can find.

Hyaline Cartilage

Lacunae are located in a background matrix
that looks fairly consistent throughout.

There are NO VISIBLE FIBERS.

The matrix looks like GROUND GLASS.

(Occasionally "chatter marks"
made by the knife that cut the tissue
may vaguely resemble fibers)

Fibrocartilage

Lacuna are located in a matrix
that has VISIBLE FIBERS.

The fibers tend to be arranged as
parallel bundles.
The fibers MAY look kind of wispy.
or MAY be bold and very wavy.
NOTE: Elastic connective tissue also has wavy fibers
but elastic CT does not have lacunae!!
Elastic CT has very flattened fibroblasts between fibers.

Elastic Cartilage

Lacunae are located in a matrix
that has VISIBLE FIBERS.

The fibers tend to be arranged as
individual strands that criss-cross each other.
The fibers stand out boldly.
The fibers tend to stain much darker
than the rest of the matrix.
