which is not correct about spongy bone?

(C) elbow O a. Biologydictionary.net, May 07, 2017. https://biologydictionary.net/spongy-bone/. In addition, bones contain bone marrow and periosteum. Get instant access to this gallery, plus: Introduction to the musculoskeletal system, Nerves, vessels and lymphatics of the abdomen, Nerves, vessels and lymphatics of the pelvis, Infratemporal region and pterygopalatine fossa, Meninges, ventricular system and subarachnoid space, Bone substance composed of thin intersecting laminae, found internal to compact bone, Reduces density and weight of bone, forms the site of hematopoiesis due to the presence of red bone marrow. no osteons, lamellae, superficial, and glossy A b. red bone marrow, canaliculi, no osteons 4 Q They differentiate and develop into osteoblasts. very outer most superficial layer of bone is called the periosteum. Perichondrium cells differentiate into osteogenic cells then into osteoblasts 3. The osteoblasts try to compensate but the new bone they lay down is weak and brittle and therefore prone to fracture. The Cardiovascular System: The Heart, Chapter 20. compact bone ? Which of the following is not associated with spongy bone ? (B) thumb tissue (b) mesenchymal cells convert to osteoblasts (c) going to be talking about what is called the haversian system. A long bone has two main regions: the diaphysis and the epiphysis (Figure 6.3.1). the bone (c) is anchored to the bone matrix by Sharpey's A. Normal leg bones are relatively straight, but those affected by Pagets disease are porous and curved. Bone Classification and Structure | Anatomy and Physiology | | Course Hero It is found in most areas of bone that are not subject to great mechanical stress. Watch this video to see the microscopic features of a bone. Figure5. see, carry their own set of small blood vessels. D) Blood-forming tissue is found in the skull and pelvic bones only. Figure9. Take a closer look at different types of bone tissue found in the human body with the study unit below: Ott S, M: Cortical or Trabecular Bone: Whats the Difference? (B) knee The answer is still unknown, but hereditary factors seem to play a role. Long bones are characterized by a shaft that is much longer than it is wide and by a rounded head at each end of the shaft. Instead, the lacunae and osteocytes are found in a lattice-like network of matrix spikes called trabeculae (singular = trabecula) ( [link] ). LM 40. Osteocytes maintain the mineral concentration of the matrix via the secretion of enzymes. Spongy bone is usually located at the ends of the long bones (the epiphyses), with the harder compact bone surrounding it. The trabeculae may appear to be a random network, but each trabecula forms along lines of stress to provide strength to the bone. It is highly vascularized and contains red bone marrow. (D) wrists, What type of freely movable joint is an example of ones that permit back and forth? If the outer layer of a cranial bone fractures, the brain is still protected by the intact inner layer. (C) Support the skin This rapid production is made possible by the highly vascularized nature of the spongy bone, which can deliver adequate amounts of the glucose, lipids, amino acids and trace elements required to make red blood cells. Osteogenic cells develop into osteoblasts. Bone tissue is a type of connective tissue consisting mainly of a collagen matrix that is mineralized with calcium and phosphorus crystals. Kozielski M, Buchwald T, Szybowicz M, Baszczak Z, Piotrowski A, Ciesielczyk B. Compact bone is dense so that it can withstand compressive forces, while spongy (cancellous) bone has open spaces and supports shifts in weight distribution. The trabeculae may appear to be a random network, but each trabecula forms along lines of stress to direct forces out to the more solid compact bone providingstrength to the bone. this arrow pointing to the trabecula of spongy bone. Identify six types of bones, and give an example of each type. 2. What is the skeleton of a newborn baby mainly composed of? It is highly vascularized and contains red bone marrow. Spongy bone is the inner framework of the bone in which the bone marrow resides. It accounts for about 80 percent of the total bone mass of the adult skeleton. (A) wrist The spongy bone and medullary cavity receive nourishment from arteries that pass through the compact bone. c. Blood vessels, dragging osteoblasts and marrow In the center of these layers is a canal called the haversian In general, their size and shape is an indication of the forces exerted through the attachment to the bone. In these studies, a dye containing a radioactive ion is injected into the body. The microscopic structural unit of compact bone is called anosteon, or Haversian system. Spongy bone is also called cancellous or trabecular bone. It presents (possesses) osteons b. Anatomy chapter 6 Flashcards | Chegg.com Spongy bone is composed of trabeculae that contain the osteocytes. Its roasted bone marrow, still inside the bones. Bone growth continues throughout childhood. This process also occurs in the liver and spleen. (D) embryos, newborn children, and teenagers, The shoulder joint is an example of Direct link to Johannes Hartig's post Spongy bone is the inner , Posted 7 years ago. They can communicate with each other and receive nutrients via long cytoplasmic processes that extend throughcanaliculi(singular = canaliculus), channels within the bone matrix.

The wider section at each end of the bone is called the epiphysis (plural = epiphyses), which is filled internally with spongy bone, another type of osseous tissue. of bone fractures (c) is involved in bone growth (d) all of (a) work with osteoblasts to remodel and Direct link to SofiyaMarkova's post No, gap junctions are in , Posted 8 years ago. Cancellous bone makes up about 20 percent of the human skeleton, providing structural support and flexibility without the weight of compact bone. Spongy (Cancellous) Bone Like compact bone, spongy bone, also known as cancellous bone, contains osteocytes housed in lacunae, but they are not arranged in concentric circles. Bones are organs that consist primarily of bone tissue, also called osseous tissue.
