Overview of skeletal
system
, Skeletal system
• The framework of the body, consisting of bones
and other connective tissues, which protects and
supports the body tissues and internal organs.
• The skeleton gives the vertebrate body shape,
supports its weight, offers a system of levers that
together with muscles produces movement, and
protects soft parts such as nerves, blood vessels,
and other viscera.
, Skeleton
The skeleton is the supportive framework
that provides structure to the body and
facilitates movement in animals.
Exoskeleton: A rigid or articulated envelope that supports and protects
the soft tissues of certain animals.
Endoskeleton: The endoskeleton is the internal support structure of an
animal, composed of mineralized tissue and is typical of vertebrates. A
true endoskeleton is derived from mesodermal tissue. Such a skeleton is
present in echinoderms and chordates.
Hydrostatic skeleton: A hydrostatic skeleton is a semi-rigid, soft tissue
structure filled with liquid and surrounded by muscles.
