DENSE CONNECTIVE TISSUE
This contains more fibres and fewer cells than loose
connective tissue.
FIBROUS TISSUE:
This is a dense fibrous connective tissue made up mainly of
closely packed bundles of collagen fibres, with very little matrix,and very few
cells lying in rows between the bundles of fibres and developed from
fibroblasts.
1.
Forming ligaments, which bind bones together.
2.
As an outer protective covering for bone,called PERIOSTEUM
3.
As an outer protective covering of some organs,
eg,the kidneys,lymphnodes and the brain
4.
Forming muscle sheaths called MUSCLE FASCIA,which
extend beyond the muscle to become the tendon that attaches the muscle to bone.
ELASTIC TISSUES :
Elastic tissue is capable of
considerable extension and recoil.
There are few cells and the matrix
consists mainly of masses of elastic fibres secreted by fibroblasts.
It is found in organs where
stretching or alteration of shape is required ,e.g in large blood vessel
walls,the trachea and bronchi, and the lungs.
LYMPHOID TISSUE
This tissue ,also known as
reticular tissue,has a semisolid matrix with fine branching reticullin fibres.
It contains reticular cells and
white blood cells (monocytes and lymphocytes).
Lymphoid tissue is found in lymph
nodes and all organs of the lymphatic system.
