Tissues Flashcards
The branch of life sciences that focuses on the tissue level of organization.
HISTOLOGY
It is composed of clusters of functionally similar (if not the same) cells which forms a functionally distinct role in the human body.
HISTOLOGY
FOUR MAJOR CLASSIFICATIONS OF TISSUES IN HUMAN BODY
EPITHELIAL TISSUES
CONNECTIVE TISSUES
MUSCULAR TISSUES
NERVOUS TISSUES
FOUR MAJOR CLASSIFICATIONS OF TISSUES IN HUMAN BODY
- Surfaces of internal anatomy and select external anatomy.
EPITHELIAL TISSUES
FOUR MAJOR CLASSIFICATIONS OF TISSUES IN HUMAN BODY
- ATTACHMENT BETWEEN DIFFERENT ORGANS AND LAYERS.
CONNECTIVE TISSUES
FOUR MAJOR CLASSIFICATIONS OF TISSUES IN HUMAN BODY
- Specialized tissue for movement or locomotion.
MUSCULAR TISSUES
FOUR MAJOR CLASSIFICATIONS OF TISSUES IN HUMAN BODY
- Specialized tissue for rapid transmission or information.
NERVOUS TISSUES
FUNCTIONS OF EPITHELIAL TISSUES
- BARRIER FOR EXTERNAL SURFACES (free surface) AND INTERNAL SURFACES (basement membrane) IN THE BODY.
- SEMI-PERMEABLE MEMBRANE FOR ABSORPTION AND RELEASE OF WASTE (vasodilation and vasoconstriction).
TYPES OF EPITHELIAL TISSUES
SIMPLE SQUAMOUS EPITHELIUM
SIMPLE CUBOIDAL EPITHELIUM
SIMPLE COLUMNAR EPITHELIUM
PSEUDO- STRATIFIED COLUMNAR EPITHELIUM
STRATIFIED SQUAMOUS EPITHELIUM
TRANSITIONAL EPITHELIUM
GLANDULAR EPITHELIUM
TYPES OF EPITHELIAL TISSUES
- Lining of oral and anal cavity; High width, Low height.
Ex. Cheek & Anus
SIMPLE SQUAMOUS EPITHELIUM
TYPES OF EPITHELIAL TISSUES
- Lining of ducts that can perform secretions as well; Equal Width and height; shape remains the same; thickened layer.
Ex. urinary bladder
SIMPLE CUBOIDAL EPITHELIUM
TYPES OF EPITHELIAL TISSUES
- Lining of gastrointestinal tract for absorption of nutrients; High height, Low width.
Ex. glands, intestine, stomach
SIMPLE COLUMNAR EPITHELIUM
TYPES OF EPITHELIAL TISSUES
- Undifferentiated columns of tall epithelium.
PSEUDO-STRATIFIED COLUMNAR EPITHELIUM
TYPES OF EPITHELIAL TISSUES
- Multiple layers that serve multiple functions in the skin; Change shape.
Ex. urinary bladder
STRATIFIED SQUAMOUS EPITHELIUM
TYPES OF EPITHELIAL TISSUES
- Can stretch depending on the shape of the organ.
TRANSITIONAL EPITHELIUM
