To identify: The anatomical regions and structures in the given image of a long bone.
Introduction: The long bones are long, high-density bones that provide the skeleton strength. They are long in the sense that their length is greater than their width. This occurs due to elongation of the diaphysis, which is the main shaft. The radius of the arm is an example of a long bone.
Answer to Problem 1CRQ
Pictorial representation: Fig.1 represents the anatomical regions and structures of the long bone representing the epiphysis.
Fig.1: Anatomical regions and structures of the long bone representing the epiphysis
Explanation of Solution
The long bones are covered by a membranous layer called the periosteum. The length of the bone forms the main shaft and is called the diaphysis. The diaphysis extends into a rounded end, which is called the epiphysis. The epiphysis refers to each rounded end part of the bones. It is very important in the growth of the bones. It is composed of an outer layer of the compact bone and the inner layer of the spongy bone.
