Epithelial Tissue
Objective:
• Classify epithelial tissues based on the number of cell
layers and the shape of the cells.
• Name and describe the various types of epithelial
tissue, including their chief functions and locations.
• Name the different structures of Epithelium in the
picture.
To do:
• Pre- lab lecture/ discussion about the Epithelial tissue.
• Picture naming of Epithelial tissue parts.
• Answer the laboratory exercise.
• Submit the laboratory report.
What is a tissue?
Tissue
• A tissue is a group of cells with similar structure and
function, plus the extracellular substance surrounding
them.
• Histology is the study of tissues.
What are the four basic types of tissue?
Types of Tissues
1. Epithelial
2. Connective
3. Muscle
4. Nervous
How does tissue structure related to its
function?
• The structure of each tissue of the body is organized
to carry out its own specific functions, and this is
reflected in the arrangement of the cells
and its histological appearance
Types and Function
1. Epithelial – a covering or lining tissue
2. Connective – a diverse primary tissue type that
makes up part of every organ in the body
3. Muscle – a tissue that contracts or shortens, making
movement possible
4. Nervous – responsible for coordinating and
controlling many body activities
How epithelial tissue is classified according to the
number of cell layers and the shape of the cells?
