BIOL&212 - Chapter 47 Review

Front

What is the role of the notochord in vertebrate development?

Back

The notochord induces the formation of the neural tube.

Front

What is the function of the fibroblast growth factor (FGF) family in limb development?

Back

The FGF family promotes limb-bud outgrowth.

Front

What is a classic model system for studying pattern formation in vertebrates?

Back

Limb development in the chick is a classic model system.

Front

What do neural crest cells form in the embryo?

Back

Neural crest cells form peripheral nerves and parts of the teeth and skull bones.

Front

What is the significance of cloning experiments in relation to cell potential?

Back

Cloning experiments show that cells can remain totipotent.

Front

Define 'totipotent' in the context of cell biology.

Back

Totipotent cells have the potential to develop into any cell type, including the entire organism.

Front

What is the difference between pluripotent and multipotent stem cells?

Back

Pluripotent stem cells can differentiate into almost any cell type, while multipotent stem cells can only differentiate into a limited range of cell types.

Front

Explain the concept of 'induction' in embryonic development.

Back

Induction is the process by which one group of cells influences the development of another group of cells.

Front

What is the significance of the neural tube in vertebrate development?

Back

The neural tube develops into the central nervous system, including the brain and spinal cord.

Front

Describe the role of fibroblasts in tissue development.

Back

Fibroblasts are responsible for producing extracellular matrix and collagen, which provide structural support to tissues.
