IMED1001 Study Guide - Final Guide: Deep Fascia, Ground Substance, Fallopian Tube
IMED1001 Tutorial Week 5
Glands:
-Epithelial specialisation as secretory structure!
-Found in epithelium of hollow organs!
-How it is formed:!
1. Epithelial cells grow !
2. Canalisation!
3. Forms hollow tube!
4. Part of tube specialises and becomes secretory!
5. Secretions carried to epithelial surfaces by duct!
6. Duct may branch and grow quite large!
Cilia (Columnar Cells):
-Hairlike!
-Anchored in cell!
-Moves small quantities of fluid on the cell surface!
-Beating movements!
-Downstroke: sharp, have fluid movement!
-Return stroke: gradual, no fluid movement!
-Ciliated cells eg. Trachea, uterine tube (fallopian)!
Goblet Cell (Columnar Cells):
-Produces mucus!
-Mucus = sticky semifluid!
-= Protein-polysaccharide complex !
-Mucus accumulate in apical portion of cytoplasm!
-Apical portion bulges like goblet!
Types of Fibres:
1. Collagen!
2. Elastic!
3. Reticular!
Loose Connective Tissue:
-Loose arrangement of fibres!
-Loose wavy collagen bundles!
-Allows stretch!
-BUT only until it is straightened !
-Then resists!
-Tissue can be stretched but has to be within limits!
-Elastic fibres = ensure restoration of tissue after stretch!
