Lesser amount of Fiber component
Predominance of Ground Substance and Cells
Has two types

RETICULAR
Loose Connective Tissue
Contains fibers, ground substances and cells in roughly equal parts
Areolar Connective Tissue

Reticular Connective Tissue
Cells in these organs are supported by reticular fibers
Reticular Connective Tissue
Reticular Connective Tissue
Forms the_____ of the bone marrow, and soft organs such as endocrine glands, liver, lymph nodes, pancreas and thymus
Cells in these organs are supported by _________
stroma
reticular fibers
Very abundant fibrous components and relatively few cells and ground substance
Dense CT
Collagen fibers are oriented parallel to one another or in ordered arrangement
DENSE REGULAR CONNECTIVE TISSUE
DENSE REGULAR CONNECTIVE TISSUE
Collagen fibers are oriented_____ to one another or in ordered arrangement
parallel
Connective tissue connecting muscles to bone
Tendons
Connective tissue connecting muscle to muscle
Aponeurosis
Connective tissue connecting bone to bone
Ligaments
Collagen bundle fibers are randomly oriented
DENSE IRREGULAR CONNECTIVE TISSUE
DENSE IRREGULAR CONNECTIVE TISSUE
Collagen bundle fibers are________ oriented
randomly
is characterized morphologically by a prominent ground substance matrix containing a loose aggregate of reticular fibers and unspecialized mesenchymal stem cells
Mesenchyme
Mesenchymal cells are usually_____ in shape.
irregular
Mesenchymal cells: COMA
Chondrocytes
Osteoblasts
Myocytes
Adipocytes
The loose fluid nature of______ allows its cells to migrate easily and play a crucial role in the origin and development of morphological structures during the embryonic and fetal stages
mesenchyme
directly gives rise to most of the body’s connective tissues, from bones and cartilage and muscles
Mesenchyme
Contains large amount of ground substances with sparse amount of collagen fibers and fibroblasts
Mucous CT
Functions to provide support
Mucous CT
