ANATOMY AND PHYSIOLOGY LAB 7 HISTOLOGY OF EPITHEALIAL TISSUE
Histology: the study of tissues and how they are arranged (microscopic anatomy)
- Important for understanding the physiology of the body
Tissue: made up of cells and matrixs
- Made up of similar cells that come together to form a tissue which performs a specific function
Cells are the smallest units of life that carry out a specific function
Muscle cell: muscle contraction
Tissues group together to form an organ
Cells tissue organ
Organ: structure that performs a job depending on the types of cells and arrangement of tissues
Tissue types:
1. Epithelial tissue: functions in secretion and absorption, roles of protection and secretion of
waste
2. Connective tissue: help to bind tissues together and anchors organs to body cavities) supportive
role)
3. Nervous tissue: specialized and serves the role of communication for the nervous system
4. Muscular tissue: specialized for muscle contraction and general movement
Tissue composition – Tissues contain matrix
Matrix: extracellular material
- Made up of a ground substance (extracellular fluid)
- Water nutrients, minerals, gases
- Contains protein fibers
Fertilization:
- Fertilized egg
- Small cells divide and group themselves into 3 primary germ layers
Germ layer
1. Ectoderm: arrangement of tissue that gives rise to the epidermis and the nervous tissue
