IMED1001: Lecture 6 Notes - Connective Tissue
Introduction:
-CT is found everywhere!
-Except CNS!
-CT main functions !
1. Connect and bind things together!
2. Strength and support (needed because cell soft)!
3. Transmit and resist forces!
4. Nutritional support!
Appearance:
-Cells scattered and far apart!
-Compared to epithelium (very compact)!
-What occupies the space among cells?!
-MATRIX!!
-Found where?!
-Intracellularly and extracellularly!
Matrix and Cells:
-Provides mechanical properties!
-Comprises of?!
1. Fibres !
-Formed elements!
-Has definite shape and form!
2. Ground substances!
-amorphous !
-No form (formless)!
-Jellylike!
-Fills all spaces!
Fibres:
1. Collagen!
-natural white colour!
-Bundles!
-Wavy!
-Resists stretching when straightened !
2. Elastic!
