Chapter 4 - Tissue Flashcards
What are the four types of tissue
Epithelial, connective, muscle, and neural
Tissue that covers exposed surfaces
Epithelial
Tissues that provides structural support
Connective tissue
Tissue that contracts to produce movement
Muscle tissue
Tissue that conducts electrical impulses
Neural tissue
Define histology
The study of tissues
Tissue found in the lining of hallow organs
Epithelial
Side of the epithelial cels that come in contact with the outside environment
Apical surface
Term for how two cells connect
Intercellular connections
Interlocking proteins that approximate one side of a cell with one side of another cell
Tight junction
Tunnel that communicates cell 1 with cell 2 in intercellular connection
Gap junction
Intercellular connection that is formed by intermediate filaments coming together
Desmosome
Three types of epithelial tissue
Squamous, cuboidal, and columnar
List three important characteristics/functions of epithelial tissue
Provides protection, allows selection permeability, and allows for sensation
Identify three main types of epithelial cell junctions
Tight, gap, and hemi-desmosome
