Connective Tissue Flashcards
What is the most abundant type of tissue?
Connective tissue
What is the most abundant component of connective tissue?
Extracellular matrix
What:
Produce intracellular substance
Join tissue elements and fill in gaps
Provide support
Defend organism by giving rise to blood and immune cells
Healing- very regenerative when needed
Connective tissue
What type of cells are surrounded by amorphous ground substance and are STEM cells for other connective tissue types?
Mesenchymal cells
What cells are spindle to stellate cells
- open face nucleus with nucleoli
- little cytoplasm
?
Mesenchymal
What type of cells are surrounded and supported by reticular collagen and fibroblasts
Originate from a mesenchymal cells
Adipocytes
What cells are specialized in storing fat as:
Multiple small droplets (brown)
Single large droplets (white fat)
Adipocytes
Which are the most common connective tissues?
Fibroblasts
What is a component of fibroblasts?
Fusiform- spindle shaped
What do fibroblasts produce?
Extracellular matrix- ECM
What part of the ECM has the functions:
Lubrication, diffusion, blockage, adhesion
Amorphous
What is a type of ECM: Amorphous
GAGs example?
Hyaluronic acid
What is a type of ECM: Amorphous
Glycoproteins example?
Laminin
What are adhesion of epithelial cells?
Laminin- glycoproteins
What part of the ECM is produced by fibroblasts?
Fibrous
ECM: Fibrous, is composed of what 2 things?
Collagen and Elastin
What is the most abundant protein?
Collagen
How many types of collagen are there?
28
What type of collagen is the most abundant?
Collagen 1
What is a very delicate type of collagen that forms a network or ‘reticulum’ for many organs?
Collagen 3
What is fibrillin + elastin =
Elastic fiber
What are produced by fibroblasts and smooth muscle cells
Interspersed with collagen bundles and provide stretching?
Elastic fibers
Connective tissue type that:
Various cell types
Thin fibers
Soft, spacious
Loose
Connective tissue type that:
Thick collagen
Few cells
Regular or irregular
Dense aka ‘fibrous tissue’
Connective tissue type that:
Reticulum fibers
Few cells
Visceral storms
Reticular
Connective tissue type that:
Elastin fibers
Moderate number of cells
Sometimes combined with smooth muscle
Elastic
Connective tissue type that:
Adipocytes
Supported by fine collagenous tissue
‘Empty’ cells- fat is lost in processing
Adipose
