The wider section at each end of the bone is called the epiphysis (plural = … Like compact bone, spongy bone, also known as cancellous bone, contains osteocytes housed in lacunae, but they are not arranged in concentric circles. 0%. Label a long bone Remaining 0. Figure 6. Diagram of Compact Bone. About this Quiz. A 'crest' on a bone is : 6. The periosteum covers the entire outer surface except where the epiphyses meet other bones to form joints (Figure 2). Osteocytes maintain the mineral concentration of the matrix via the secretion of enzymes. When occurring in the skull, Paget’s disease can cause headaches and hearing loss. Shaylin Stranges BIO 115 Exam 3 A. Skeletal System 1. And the overall effect of this spongy network in the center of the bone is that of making the bone lighter. Every long bone is capped with wide areas on each end which are called epiphyses. This is an online quiz called Long Bone Anatomy. structure of a long bone Long bone: elongated bone consisting of a body (diaphysis) and two terminal parts (epiphyses), such as the leg and arm bones (femur, radius, phalanges and others). It is important for bones to be strong to support our body weight. These salt crystals form when calcium phosphate and calcium carbonate combine to create hydroxyapatite, which incorporates other inorganic salts like magnesium hydroxide, fluoride, and sulfate as it crystallizes, or calcifies, on the collagen fibers. Here we explain the anatomy of bone and the function of each part. 2 APR ASSESS CRITICAL THINKING Explain How Bone Cells Embedded In A Solid Ground Substance Obtain Nutrients And Eliminate Wastes.. 4.

Examples of long bones are the femur, tibia, and fibula of the leg, the humerus, radius, and ulna of the arm, and the phalanges of the fingers and toes. Osteoclasts are continually breaking down old bone while osteoblasts are continually forming new bone. Label the Parts of a Long Bone. Each osteocyte is located in a space called a lacuna and is surrounded by bone tissue. Each osteon is composed of concentric rings of calcified matrix called lamellae (singular = lamella). They make up part of the growth plate, and during childhood, cells in the metaphysis divide for longitudinal bone growth. Each epiphysis meets the diaphysis at the metaphysis, the narrow area that contains the epiphyseal plate (growth plate), a layer of hyaline (transparent) cartilage in a growing bone.

The outer surface of the bone is covered with a fibrous membrane called the periosteum (peri– = “around” or “surrounding”). The metaphyses are also important for bone growth during childhood and adolescence. Pelvis Bone Structure Picture. Parts of the Skeletal System (Source: Britannica) The skeletal system is made up of bones and cartilage. Some, like the rib cage, provide protection for softer body parts, while other bones enable mobility by supporting the muscles. Purpose of the Exercise To review the way bones are classified and to examine the structure of a long bone. These include the periosteum, compact bone, spongy bone and an inner core of bone marrow. When osteoblasts get trapped within the calcified matrix, their structure and function changes, and they become osteocytes. What is the classification of this bone according to its shape? What is label number 4 pointing to … Paget’s disease usually occurs in adults over age 40.

Learning Outcomes After completing this exercise, you should be able to 1 Locate the major structures of a long bone. They can communicate with each other and receive nutrients via long cytoplasmic processes that extend through canaliculi (singular = canaliculus), channels within the bone matrix. For this reason the medullary cavity is also called the marrow cavity. Figure 2. Periosteum and Endosteum. a = epiphysis b = diaphysis c = articular cartilage d = periosteum f = compact bone g = medullary cavity (yellow marrow) h = endosteum ... Label the Structures of the Pelvis. Drag the labels to identify the structures of a long bone. See long bone anatomy stock video clips.
