Chapter 15: Problem 8

Complete the following sentences. Shaft of a long bone is the ______ .

Short Answer

Expert verified
The shaft of a long bone is the diaphysis.

Step by step solution

01

Understand the Question

The exercise asks to identify the part of a long bone referred to as the shaft.
02

Recall Anatomy of a Long Bone

Long bones, such as the femur or humerus, have distinct parts including epiphysis (ends), metaphysis (neck region), and diaphysis (shaft).
03

Define the Shaft

In anatomical terms, the shaft of a long bone is defined as the diaphysis, which is the central tubular part.
04

Complete the Sentence

Using the knowledge from the previous step, complete the sentence: Shaft of a long bone is the diaphysis.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Understanding the Diaphysis
The diaphysis is the main or midsection of a long bone. It is often referred to as the bone shaft. This long, cylindrical structure is crucial in providing support and strength to the bone. The diaphysis is made up primarily of compact bone, ensuring its durability and ability to withstand various physical stresses.

In the diaphysis, you will also find the medullary cavity, which is a central hollow area. This cavity is vital as it contains yellow bone marrow, important for fat storage. The surface of the diaphysis is covered by a thin layer known as the periosteum, which plays a role in bone nourishment and repair.
  • Structure: Solid outer layer of compact bone surrounding the medullary cavity.
  • Function: Provides structural support and is a site for marrow storage.
  • Components: Composed of compact bone and houses yellow marrow.
Exploring the Epiphysis
The epiphysis refers to the rounded ends or terminal sections of a long bone. Each long bone has at least two epiphyses, one at each end. Composed primarily of spongy bone, these areas are abundant in red bone marrow, essential for the production of blood cells.

The epiphysis plays a vital role in joint movement and stability, as they articulate with neighboring bones. The surface of the epiphysis is lined with articular cartilage, a smooth tissue that allows for easy, frictionless movement.
  • Structure: Contains spongy bone and is covered by articular cartilage.
  • Function: Facilitates movement and supports joint function.
  • Components: Houses red marrow, important for hematopoiesis.
All About the Metaphysis
The metaphysis is the narrow portion of a long bone located between the diaphysis and epiphysis. During childhood and adolescence, the metaphysis contains the epiphyseal plate (or growth plate), which is responsible for the lengthwise growth of bones.

As a child grows, the cartilaginous tissue in the epiphyseal plate gradually ossifies and turns into bone, indicating the completion of bone growth. In adults, this area becomes the epiphyseal line, marking the location of previous growth.
  • Structure: Transition area between the diaphysis and epiphysis.
  • Function: Site of bone growth during development.
  • Components: Contains growth plate during development and ossification elements.
