Connective Tissue Flashcards
(24 cards)
What are the 3 things that all connective tissue has?
- Specialized cells
- Fibers
- Fluid known as Ground Substance
What is ground substance?
Its similar to the plasma of the blood. Viscus stuff that the fibers and cells float in.
What makes up the Matrix?
Fibers and ground substance
What is the main volume of connective tissue?
Extracellular matrix
Is connective tissue vascular or Avascular?
Vascular
What are the functions of connective tissue?
- Establishing a structural framework for the body.
- Transporting fluids and dissolved materials.
- Protecting delicate organs.
- Supporting, surrounding, and interconnecting other types of tissue.
- Storing energy, especially in the form of triglycerides.
- Defending the body from invading microorganisms.
What are the 3 categories of CT used for classification?
Ordinary CT Fluid CT Supporting CT
What are the 2 types of Ordinary CT?
Loose and Dense CT
What are the 2 types (examples) of Fluid Connective tissue
Blood and Lymph
What are the 2 types (examples) of Supportive Connective Tissue?
Bone and Cartiladge
Name 4 cells that you would find in the connective tissue that deal with repair and maintenance?
Fibroblasts, fibrocytes, adipocytes, and mesenchymal cells
Name 4 additional cells that you could find in Ordinary connective tissue regards to pathogens?
Macrophages, mast cells, lymphocytes, plasma cells, and microphages
Name 3 loose Connective Tissues and location examples?
Adipose - Hypo dermis Areolar - Deep dermis Reticular - Liver, kidney, spleen
Name 3 Dense Connective Tissues?
- Dense Regular
- Dense Irregular
- Elastic Tissue
Give an example of Dense Regular tissue?
Tendons, Ligaments
Give and example of Dense Irregular tissue?
Skin - deep dermis
Whats the name of a nucleus that’s off center?
Eccentric Nucleus
Name the 3 types of fibers found in connective tissue?
Collagen Fibers Elastic Fibers Reticular Fibers
What are the features of Collagen fibers and where are they found?
They are tough, yet flexible, rope like fibers. They DO NOT stretch. Tendons, Ligaments
What are the features of Elastic Fibers?
They aren’t as thick as Collagen fibers but form a net/mesh of fibers. Found in skin to help it bounce back into shape. Is stretchy.
What is the name of a large molecule found in the ground substance?
Glycosaminoglycans (GAG’s)
From the embryo, where does connective tissue originate and what embryo cell?
Mesoderm layer but more specifically the mesenchymal cell
What is the main cell in connective tissue?
Fibroblasts
What are fibroblast responsible for making?
Collagen, Elastin, GAG’s and Proteoglycans
