Connective Tissue Flashcards
CONSTITUENCIES OF CONNECTIVE TISSUE
● Fibers
● Cell
● Ground Substance
TYPES OF FIBERS
● Elastic fibers
● Collagen fibers
● Reticular fibers
found in organs that are subjected to bending and stretching
Elastic fibers
Function: to provide rigidity and strength
Collagen fibers
Collagen fibers Synthesized by:
Fibroblast of the connective tissue
also referred to as COLLAGEN TYPE 3
Reticular fibers
NOT stained with H and E
Reticular fibers
stained with pink color by H and E
Collagen fibers
Reticular fibers Requires special stain
SILVER
→ SILVER - imparts _______ COLOR to the fibers
black
Silver stains what fibers? (BELLPaTS)
B = Bone Marrow
E = Endocrine Glands
L = Lymph Nodes/
L = Liver
Pa = Pancreas
T = Thymus
S = Spleen
TYPES OF CONNECTIVE TISSUES
Embryonic Connective Tissue
Mature connective tissue
→ Mesenchyme
→ Mucous connective tissue
Embryonic Connective Tissue
→ Loose connective tissue
→ Dense connective tissue
Mature connective tissue
→ Skin
Elastic fibers
→ Lungs
Elastic fibers
→ Aorta and its branches
Elastic fibers
→ Pulmonary artery

EMBRYONIC CONNECTIVE TISSUE
(Fibroblast) Cells «< Ground substance»_space;> (Collagen) Fibers
Mucous Connective Tissue
Very abundant fibrous components and
→ Relatively few cells and ground substance
Dense Connective Tissue
Dense Connective Tissue 2 TYPES
DENSE IRREGULAR CT; DENSE REGULAR CT
Collagen bundle fibers are randomly oriented
→ DENSE IRREGULAR CT
▪ Collagen fibers are oriented parallel to one another or in ordered
arrangement
DENSE REGULAR CT
Reticular dermis of the skin
DENSE IRREGULAR CT
Capsules of organs
→ DENSE IRREGULAR CT
Tunica albuginea of testes
→ DENSE IRREGULAR CT
Tendons
DENSE REGULAR CT
− Dura mater of the brain submucosa of the digestive tract
DENSE IRREGULAR CT
Aponeurosis
DENSE REGULAR CT
Ligaments
DENSE REGULAR CT
Corneal Stroma
DENSE REGULAR CT
=> CT connecting muscles to bone
Tendons
CT connecting muscles to muscle
Aponeurosis
CT connecting bone to bone
Ligaments
Lesser amount of Fiber component
Loose Connective Tissue
Predominance of Ground Substance and Cells
Loose Connective Tissue
Loose Connective Tissue TWO TYPES
AREOLAR; RETICULAR
Cells = Ground Substance = Fibers
→ AREOLAR
Cells»_space;> Ground substance = Fibers
RETICULAR
contains fibers, ground substances, and cells in roughly equal
parts
AREOLAR
forms the stroma of the bone marrow, and soft organs
RETICULAR
found underneath the epithelium
AREOLAR
Lamina propria of the digestive tract
AREOLAR
Surrounds blood vessels and nerves
