LØØSË ÇØÑÑËÇTÏVË TÏSSÜË
In this, cells (fibroblasts, macrophages, mast cells, etc.) and fibres are
loosely arranged in a semi-fluid matrix.
It is of 2 types: Areolar & Adipose.
Areolar tissue:
Most widely distributed
connective
tissue
in
animal body.
Present
beneath
the
skin.
It serves as a support
framework for epithelium. It contains fibroblasts, macrophages and
mast cells.
Adipose tissue:
Seen mainly under skin. Its cells (adipocytes)
store fats. Excess nutrients which are not used
immediately converted into fats are stored in
this tissue.
DËÑSË ÇØÑÑËÇTÏVË TÏSSÜËS
In this, fibres and fibroblasts are compactly packed. Orentation of fibres
show a regular or irregular pattern and are called dense regular and
dense irregular tissues. It is of 2 types:
Dense regular
connective tissues:
Show regular pattern of
fibres.
Collagen fibres are present
in
rows
between
many
parallel bundles of fibres. E.g.
Tendons & ligaments.
Tendons: Attach skeletal
muscles to bones.
Ligaments: Attach one
bone to another.
Dense irregular
connective tissues:
Irregular pattern of fibres.
Fibroblasts & fibres (mostly
collagen) are oriented
differently. This tissue is
present in skin.
