The outer covering of bone, the periosteum, is composed of which type of connective tissue?
Dense irregular connective tissue
The elongated cylindrical shaft of a long bone is called its
Diaphysis
Growth hormone exerts its primary effect on which of the following?
Growth of cartilage
Which statements describe the matrix of bone?
It is composed of organic and inorganic substances. It is harder than the matrix of cartilage.
It covers the outer surface of the diaphysis of a long bone. It is composed of dense irregular connective tissue. It functions to anchor blood vessels to the surface of bones.
Periosteum
One effect of growth hormone (GH) is the stimulation of cartilage growth. How might a decrease in GH production during development impact a person?
Result in a decrease in height
Why might astronauts, who spend only a few days in outer space under microgravity (reduced gravity), experience a significant loss in bone density?
The decrease in gravity causes a decrease in osteoblast activity and thus a decrease in bone density.
Which statements characterize osteocytes?
They reside in lacunae. They maintain bone matrix.
