tel molt fi i transparent.

A continuació vàrem treure els
músculs que s’uneixen als ossos
mitjançant unes cordes blanques i
molt resistents anomenades
tendons.

Observàrem els ossos. Els extrems dels ossos
estan recoberts de cartílag, un material que no
es desgasta amb el fregament. Per últim vàrem
trencar l’os i vàrem veure el seu interior.
