Bone is a mineralized connective tissue that exhibits four types of cells: osteoblasts, bone lining cells, osteocytes, and osteoclasts [1 1. It plays important roles in mastication (chewing), tongue movement, phonation, and swallowing. 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). Any information here should not be considered absolutely correct, complete, and up-to-date. The temporal bone or os temporale is a paired, irregular bone and the thickest in the human body, located at the sides and base of the skull. The core of a long bone is filled with marrow. PLAY. V CONCLUSION. Bone tissue is a type of dense connective tissue. As part of the neurocranium, the parietal bone helps to form the shape of the head and protect the brain. It is a process involving the breakdown of bone by specialized cells known as osteoclasts. This term may also refer to abnormal processes that result in kidney and gall stones. Both bones cover the left and right parietal lobes of the brain respectively. Definition.
