'''هډوانه''' (''په انګرېزي: Skeletn'') يا '''هډوانيز غونډال''' (''په انګرېزي: Skeletal System'') په ژونپوهنه کې يو بيالوژيکي غونډال دی چې يو اورګانيزم ته فيزيکي ملاتړ وربښي. (By extension, non-biological outline structures such as [[Gantry (rocketry)|gantries]] or [[building]]s may also acquire skeletons

''' [[Exoskeleton]]s are external, as is typical of many [[invertebrate]]s; they enclose the soft tissues and organs of the body. Exoskeletons may undergo periodic [[moult]]ing as the animal grows. [[Endoskeleton]]s are internal, as is typical of many [[vertebrate]]s; they are usually surrounded by skin and musculature, though they often enclose vital organs. Endoskeletons are attachment points for musculature and act as leverage for movement, and in many animals contain [[marrow]], which produces blood cells. Skeletons may or may not be [[biomineralization|mineralized]] - human skeletons are calcified, while shark skeletons are cartilaginous - and may be jointed for flexibility and motility or rigid for structural strength.
 
The average adult [[human skeleton]] has around 206 [[bone]]s. <ref> [http://www.enchantedlearning.com/subjects/anatomy/skeleton/Skelprintout.shtml Human Skeleton], ''EnchantedLearning.com'', [[2008-05-07]]. </ref> These bones meet at [[joints]], the majority of which are freely movable. The skeleton also contains [[cartilage]] for elasticity. [[Ligaments]] are strong strips of fibrous connective tissue that hold bones together at joints, thereby stabilizing the skeleton during movement.
