Exam 39: Structure and Function of the Musculoskeletal System

MATCHING Match the stages of wound healing of a bone with the description of each.Stages may be used more than once. -Periosteal and endosteal surfaces of the bone are formed to the size and shape of the bone before the injury.

An osteocyte is a transformed osteoblast that obtains nutrients from capillaries in the canaliculi and helps maintain mineral homeostasis.

Which ion directly controls the contraction of muscles?

Which bone cells are large,multinucleated cells of the bone that develop from mononuclear phagocytic cells and contain lysosomes filled with hydrolytic enzymes?

What happens when bone is "resorbed" during the process of growth and repair?

Synovial fluid consists of chondrocytes (cartilage cells),intercellular matrix,protein polysaccharides,and water.

What acts as a pump to control the movement of synovial fluid through the cartilage?

Articular cartilage is anchored to the underlying bone via:

Muscle fibers are termed type I (red)or type II (white).Which is a characteristic of type II fibers?

How is -glycoprotein different from albumin?

Remodeling is a three-phase process in which existing bone is resorbed and new bone is laid down to replace it.

MATCHING Match the stages of wound healing of a bone with the description of each.Stages may be used more than once. -Osteoblasts form membranous or woven bone.Enzymes increase the phosphate content and permit the phosphate to join with calcium to be deposited.
