What are three main components of connective tissue?
Components of connective tissue All forms of connective tissue are composed of (1) extracellular fibres, (2) an amorphous matrix called ground substance, and (3) stationary and migrating cells. The proportions of these components vary from one part of the body to another depending on the local structural requirements.
Which cells secrete fibrous material that holds the other tissues in position?
1: Loose connective tissue: Loose connective tissue is composed of loosely-woven collagen and elastic fibers. The fibers and other components of the connective tissue matrix are secreted by fibroblasts.
How do elastic fibers differ from collagen fibers and reticular fibers?
Reticular fibers are continuous with collagen fibers through the exchange of these collagen fibrils. Elastic fibers and laminae are continuous with networks and/or bundles of microfibrils (or oxytalan fibers), and form an elastic network specific to individual tissues.
Which property is most consistent in all connective tissues?
Collagen: Collagen fibers are the strongest and most abundant of all the connective tissue fibers. Collagen fibers are fibrous proteins and are secreted into the extracellular space and they provide high tensile strength to the matrix.
What are fibers in connective tissue?
The organic portion or protein fibers found in connective tissues are either collagen, elastic, or reticular fibers. Collagen fibers provide strength to the tissue, preventing it from being torn or separated from the surrounding tissues. Reticular fibers are the third type of protein fiber found in connective tissues.
What types of fibers are found in connective tissue?
Loose and dense connective tissue are made up of the following three fibers: collagen fibers, reticular fibers, and elastin fibers.
What produces the collagen fibers in dense regular connective tissue?
The fibroblasts in the matrix generate these fibers. In dense regular connective tissue, the collagen fibers are arranged in parallel bundles. It makes it suitable for binding body parts together. It has great tensile strength resisting pulling forces particularly from a single direction.
What is the most typical type of connective tissue?
Fibroblasts
Fibroblasts are the most common cell type of connective tissue. They produce both fibers and amorphous ground substance. Typically only the oval nuclei are visible.
What is consistent in all connective tissues?
They all have collagen and elastic fibers in their extracellular matrix. Also common to all connective tissues is the presence of cells and an extracellular matrix that consists of fibers bathed in ground substance. Under a microscope you observe a tissue that appears to have long fibers that appear striated.
What are the three fiber types found in fibrous connective tissue?
The three types of connective tissue fibers are:
- Collagen fibers – most are type I collagen (most abundant protein in the body)
- Elastic fibers – contain elastin and fibrillin.
- Reticular fibers – contain type III collagen.
What kind of fibres are in the connective tissue?
Connective tissues contain three types of fibres: collagen, elastic and reticular Collagen fibres are the most widespread and made up of fibrous protein, collagen. Collagen fibres are flexible and have high tensile strength (comparable to steel).
Which is the hardest connective tissue in the body?
Cartilage possesses elasticity, but is firm too. They lack nerves, blood and lymph vessels. Bones: Bone is the hardest connective tissue and helps in maintaining the shape and posture of the body, it protects internal organs. They are rich in collagen fibres and calcium, which give strength.
What is the function of dense connective tissue?
Dense Connective Tissue. In the dense connective tissue, fibroblast cells and fibres are compactly packed. Their main function is to support and transmit mechanical forces. They are somewhat less flexible than loose connective tissue. On the basis of the arrangement of collagen fibres, they are divided into two types:
Which is an example of a specialised connective tissue?
Specialised Connective Tissue Other than these, there are supportive connective tissues, that help in maintaining correct posture and support internal organs, e.g. cartilage and bone. Blood and lymph are fluid connective tissues that circulate in the body and help in interaction and communication among all the organs.
