Monty Python and the Holy Grail

Claim: The woman is a witch

Data: She looks like one, and weighs the same as the duck

Warrant: If she looks like one and weighs the same as a duck, then she is a witch

Backing: witches are made of wood and float, so if she weighs the same on the scale as a duck than she will be determined a witch

Reservation: They faked her looking like a witch

Qualifier: If a woman is a witch than she should be burned to death because witches are bad

[The three-dimensional ultrastructure of the collagen fibers, reticular fibers and elastic fibers: a review].

Claim:Fibrous components of the connective tissue are light-microscopically classified into three types: collagen fibers, reticular fibers and elastic fibers.

Data:The collagen fibers are shaped like tapes or cords about 1 to 20 microns in diameter. Each fiber is a bundle of fibrils running roughly parallel to each other.

Warrant:These fibers are considered to play an important role not only in adhering the cells to the collagen fibers, but also in constituting the skeletal framework suitable for individual cells and tissues.

Backing:The elastic fibers consist of two different components: elastin and fibrillin.

Resevation: Elastin forms unit fibrils of 0.1-0.2 micron thickness which are arranged in bundles or laminae specific to individual organs and tissues.

Qualifier:For a comprehensive understanding of the fibrous components in the connective tissue, the author proposed categorizing them into two systems: the collagen fibrillar system as a supporting framework of tissues and cells, and the fibrillin-elastin fibrillar system for distributing stressing forces uniformly in tissues.

Collagen structure of tendon relates to function.

CLAIM: a tendon is a tough band of fibrous connective tissue that binds muscle to bone, and have crimps in the cells that allow extra stretching

DATA: under a microscope a tendon shows crimped cells that flatten in the first stage of stretching

WARRANT: A tendon can stretch more easily becuse its tissue cells are crimpted to allow extra stretching

BACKING: This theory has been tested to prove furthur stretching in the tendons of the body.

RESERVATION: Stretching varies in collagen tissues among individuals

QUALIFIERS: tendons differ in collagen compisition to create easier movement and stretching
