• Histology - the study of tissues
There are four general classifications of human
tissues, based on structure and function.
Epithelial tissues cover the body and organ surfaces; line the body and cavities and form
glands.
Connective tissues bind, support and protect body parts.
Muscle tissues contract to produce movement.
Neural tissues initiate and transmit nerve impulses from one body
part to another.

• Current Research Questions
• How do cells know into what tissue they are to mature?
• How do tissues maintain their structural and functional identity?
• How do tissues coordinate their activities within the body?
• Why can some tissues regenerate and not others?
• Why can human fetuses regenerate limbs? • Why do newborn babies rarely scar?
