Biology Basics: Important Components of Eukaryotic Cells, Common Latin and Greek Roots in Biology Vocabulary. The functions of the bone matrix proteins are potentially multifaceted ranging from Ca 2+ and hydroxyapatite binding, mineralization, bone cell attachment to tissue growth and differentiation. The major functions of bones are to provide structural support (act as the body’s framework) and to protect internal organs. Synonym (s): os [TA]. All Rights Reserved. The os temporale also provides attachment points for numerous muscles. More specifically, both bones form part of the calvaria (skull cap) and skull base (basicranium).
