Histology |
Study of tissues. |
|
|
4 Types of Human Body Tissues |
1 - Epithelial 2 - Connective 3 - Muscular 4 - Nervous |
|
|
Epithelial |
- Provide Protection - Mechanical Barrier - Prevents Entry of Microbes **Microbes: Micro-organism like bacteria, fungi, pathogen (disease causing organism). ie: Lining of GI Tract, Skin Surface |
|
|
Connective |
- Provide Support ie: Skeleton, Tendons |
|
|
Muscular |
- Facilitates Movement - Blood movement via Cardiac Muscle - Movement of food via Gastrointestinal Tract ie: Cardiac Muscle, Smooth Muscle, Skeletal |
|
|
Nervous |
- Coordination of Biochemical Process ie: Brain, Spinal Cord, Nerves |
|
|
3 Categories of Epithelial Tissue (ET) PROTECTION |
1-Simple: One layer (skin) 2-Strattified: Several Layers (skin on palms/soles) 3-Pseudostrattified: False Layers (intestines) |
|
|
Classification of Epithelial Tissues -Based on shape of cell |
- Squamous - Cuboidal - Columnar - Ciliated Columnar - Transitional |
|
|
Squamous |
- Flat - Any shape - Irregular shape - Both simple & Strattified Found in: Epidermis & Lungs **Epidermis: Outermost layer of skin |
|
|
Squamous |
|
|
|
Cuboidal |
- Cube-like Found in: Kidney Tubules |
|
|
Cuboidal |
|
|
|
Columnar |
- Column-like -Tall Found in: Intestines |
|
|
Columnar |
|
|
|
Ciliated Columnar |
- Contains Cilia - Movement of dust particles in lungs, trachea, esophagus - Movement of egg in fallopian tubes (ectopic pregnancy = failure of cilia) Found in: lungs, trachea, esophagus, fallopian tubes |
|
|
Transitional |
- Elasticity (Expand & Contract) Found in: Uterus & Bladder |
