Connective Tissue Flashcards
What has Lots of matrix and highly vascular
Composed of cells
Connective tissue
What is extra cellular made of and explain what is collagen, reticular, and elastic
Ground substance- very small and gelatinous
Fiber-
Collagen- strength
Reticular- support
Elastic- allows strength and recoil
What are the two types of connective tissues and what are in the two
Dense- lots of fiber
- dense regular
- dense irregular
loose-lots of ground substance
- areolar
-adipose
-reticular
What CT has
Location- hypodermic (fat) around heart and kidney
Function- energy storage and cushion organ
Adipose CT
What CT
Function- passage way connects and protects tissue and organs
Location- subcutaneous layer deep to skin, around heart and kidneys, yellow bone marrow, padding around joints and behind eyeball in eye socket.
Areolar CT
What CT
Location- lymph nodes, spleen
Functions- frame work and made of reticular fibers
Reticular CT
What CT
Location-ligaments and tendon
Function- collagen fiber all in one direction
Dense regular
What CT
Location-skin lowest layer and eyeball
Function-random arregned collagen fiber and different directions
dense irregular
What junction Cell membrane adhered
Tight junction
What junction Cell cytoplasm to communicate
Gap junction
What anchored cells together
Adhesion
What the difference between adipose and dense regular CT
Adipose:
- less organized
- insulation energy and cushion
- loc: hypodermis
- papillary layer
Dense irregular:
- more organized
- strong tensile str
- tendons, ligaments
- reticular layer
