Summary Introduction
Introduction:
Vitamins are the substances, which the body requires to develop and grow naturally. Vitamin D helps the body absorb calcium. Calcium is one of the prime building elements of the bone. A lack of vitamin D can result in bone disorders, like rickets or osteoporosis. Vitamin D also exhibits a function in the muscle, nerve, and immune systems.

Indicate of the statements are TRUE or FALSE.
Statements
TRUE
FALSE
Production of blood cells is NOT a function of skeletal system.
Thyroid hormone may produce either osteogenesis or osteolysis.
Bone matrix is composed primarily of Calcium and Magnesium which maybe withdrawn in small amounts as needed elsewhere in the body.
Remodelling of bone is a function of osteoclasts and osteoblasts.
A combination of the hormone, adrenal cortisol, and the bone cell, osteoclast, may result in osteoporosis.
The addition of bone to its outer surface resulting in growth in diameter is called apposional growth.
Once an individual reaches skeletal maturity, the bones undergo years of metabolic rest.
Mitosis resulting in elongation of bone occurs at the articular cartilage.
Most bones of the body are formed by intramembranous ossification.
Why is a client with osteoporosis prone to fractures?
The client has porous bones
The client has increased bone density
The client has bone spurs that lead to fracture
The client is not prone to fracture
