Chapter 6 bones and skeletal tissues

Pearson chapter 6 bones and skeletal tissues

Skeletal tissue and fibrocartilage Found in vertebral pads and pubic symphasis; compressible due to high tensile strength; a good example is the meniscus (knee pad), which sits on top of the tibia and resists femur compression.
Bone-related landmarks (bulges, depressions, and holes) Attach muscles, ligaments, and tendons; shape joint surfaces (ball and socket); and serve as blood vessel and nerve conduits (holes)
Functions and physiology of a spongy bone Struts are not soft; they disperse (or spread out) stress over a compact bone surface, which helps to keep the stress off a single small region. The spongy bone contains bone marrow.
Periosteum is a type of periosteum. Around the bone; contains perforating (Sharpey’s) fibers that bind the tissue to the bone; double-layered protective membrane (outer and inner layer); contains abundant nerves and blood vessels.
Infants’ red marrow (hematopoietic tissue) Most of the red blood cells that will remain throughout your life are produced throughout the red marrow when you’re a child; contained throughout the medullary cavity of diaphysis and all regions of spongy bone; most turns yellow at puberty; most of the red blood cells that will remain throughout your life are made in the red marrow when you’re an infant; most of the red blood cells that will remain throughout your life are made in the red marrow when you’re an infant.

Chapter 6 bones and skeletal tissues review questions

Broad bones with expanded ends. Bone is lightweight on the outside and spongy on the inside. Articular cartilage covers the joint surface (hyaline cartilage). The diaphysis and epiphyses are separated by the epiphyseal line (metaphysis). Hyaline cartilage from the epiphyseal plate that lengthens the bones during childhood.
Bone’s double-layered defensive membrane. Tendons and ligaments use this as a point of attachment. Dense normal connective tissue makes up the outer fibrous layer. Osteoblasts and osteoclasts make up the inner osteogenic layer. Nerve fibers, blood vessels, and lymphatic vessels all penetrate the bone by nutrient foramina. Sharpey’s fibers anchor the underlying bone.
Bone and periosteum are woven together. Between embryonic blood vessels, which shape a random network, accumulating osteoid is laid down. Instead of lamella, a network of trabeculae forms. The periosteum is formed when vascularized mesenchyme condenses on the external face of the woven bone.
A lightweight bone collar forms, and red marrow emerges. Just below the periosteum, trabeculae thicken and form a woven bone collar, which is later replaced with matrue lamellar bone. Internally, a spongy bone (diploe) with distinct trabeculae persists, and the vascular tissue becomes red marrow.

Chapter 6 bones and skeletal tissues 2020

• Talk about the chemical makeup of bone.
Hyaline cartilage• Most plentiful skeletal cartilage• Provides protection and flexibility• Chondrocytes look spherical under the microscope• Fiber in matrix is collagen• Found at ends of long bones at movable joints, costal cartilage linking ribs to sternum, found in larynx, nasal cartilage
Bone that is compact
• The Haversian system is made up of structural units called osteons.
• Lamella– a matrix tube• Osteon– a group of hollow bone matrix tubes
• Central canal—located at the center of the osteon and containing blood vessels and nerve fibers• Volkmann’s canal—located at right angles to the central canal and containing blood vessels and nerve fibers
• Organic components—bone tissue cells; osteoid (organic portion of matrix—collagen)• Inorganic (hydroxyapatites) or mineral salts account for 65 percent of bone mass—mainly calcium phosphates packed around collagen—make bone strong

Child (Figure 6.1) Observing Bones Bone is made up of living cells. Unlike the bones of a fossil that have become inert due to mineralization, the bones of a child will continue to grow and develop whilst supporting and functioning other body systems. (Photo courtesy of James Emery)
Bones make excellent fossils. While the soft tissue of a once-living organism will degrade and fall away over time, bone tissue will undergo a process of mineralization, eventually converting the bone to stone, if the right conditions are met. Much as your skeleton helps determine your size and shape, a well-preserved fossil skeleton will give us a clear idea of the size and shape of an organism. Your skeleton, unlike a fossil skeleton, is a living tissue structure that develops, fixes, and renews itself. The bones that make up the structure are dynamic and complex organs that perform a variety of important functions, including those that are needed for maintaining homeostasis.
