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.

Which is a characteristic of type II (white) muscle fibers?

Which bone cells are responsive to parathyroid hormone, produce osteocalcin when stimulated by 1,25-dihydroxyvitamin D, and synthesize osteoid?

The outer layer of the periosteum contains blood vessels and nerves that penetrate to the inner structures of the bone by way of:

The bone cells that are large and multinucleated and contain lysosomes filled with hydrolytic enzymes are the:

Which hormone influences the rate of protein synthesis of skeletal muscles?

The elbow joint is an example of a(n):

A function of Sharpey fibers is to:

Match the stages of wound healing of a bone with the description of each. Stages may be used more than once. -Fibrin and platelets form a meshwork within the initial framework for healing.

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.

Which of the following cells function to maintain bone matrix?

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

During isotonic contraction the muscle maintains a constant length as the tension is increased, but as the muscle contracts the limb does not move.

Diarthroses are the most movable and the most complex joints.

The part of an injured joint that becomes insensitive to pain and regenerates slowly and minimally is the:

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

A functional muscle contraction in which the muscle contracts but the limb does not move is referred to as being:

The fibrocartilaginous joints between the ribs and sternum are an example of which type of joint?

Match the stages of wound healing of a bone with the description of each. Stages may be used more than once. -Osteoblasts continue to restore callus with lamellar bone or trabecular bone.

Which ion directly controls the contraction of muscles?
