Compact bone ppt 10). Compact bone Outer layer of bone, very hard and dense. There are different types of epiphysis including pressure, traction, and aberrant epiphysis that develop in response to stresses on the bone. 1 of 58. Cancellous Bone (Trabecular Bone):It is made up of a meshwork of trabeculae (rods & plates) between which are marrow containing spaces. Types of Bone Cells • Osteocyte: Mature bone cell • Osteoblast: Bone-forming cells • Osteocast: Bone-destroying cells Remember, bone is a living tissue!. Cancellous bone is found at the ends of bones and contains trabeculae that form an open, porous structure with bone marrow. The fibers provide tensile strength, while proteoglycans in the Microscopic Structure of Compact Bone. 7 Download ppt "BONE HISTOLOGY.

On Basis of Tissue Architecture On basis of architecture, bone tissue can be divided into two types • Compact / Cortical Bone • A compact, dense layer forms the outside of the bone (80% mass) • Appears solid to the naked eye • Spongy / Cancellous / Trabecular Bone • A sponge-like meshwork of trabeculae forms the interior of the bone (20% mass) • It contains a network of It is having sandwich like structure, compact bone covering a core of spongy bone. ): fecta – and increase bone fragility (Ralston and McInnes, 2014). Bones are composed of compact and spongy (cancellous) bone. In compact bone, you will find the three bone lamellar system in an orderly manner – #1. OSTEOPROGENITOR cells are unspecialized cells derived from mesenchyme, the tissue from which all connective tissues are derived. Updated: 11/21/2023 1. This is usually a few milimiteres long and 0. • 6-4 26. Cortical bone comprises three elements: lamellarbone, and between compact and cancellous bone. There are two types of marrow in adults, yellow bone marrow, and red bone marrow. sa. It is found beneath the periosteum of all bones and makes up the bulk of the diaphyses of long bones. In growing bone, this is the site where growth occurs and is known as the epiphyseal growth plate. 67. 20. • Called Bundle bone as numerous bundles of Sharpey’s fibres pass into it from 12. They are made up mostly of compact bone, with lesser amounts of marrow, located within the medullary cavity, and spongy bone. In this simulation, approximations were used for the modelling of the lamellae and the o 3. 7. 093A . Histologically, the compact bony tissue is made up of several minute cylindrical structures called osteons or Haversian system Each osteon is formed by several layers of collagen lamellae (Haversian lamellae) arranged 22. • Irregular bones – do not fit into the above categories. forms at a rate of 1-2 um/day. 1. Bone has a unique structure that allows it to protect organs, provide muscle attachment, and facilitate movement. ppt from ANAT 260 at West Coast University. Bone Structure Bone in children and adults is of two types: compact or cortical bone, which makes up the outer layer of most bones and accounts for 80% of the bone in the body; and trabecular or spongy bones inside the cortical bone, which make up the remaining 20% of bone in the body. Collection of 100+ Compact bone slideshows. 3 Figure 5. James Montgomery, DVM September 22, 2008. Long bones – typically longer than they are wide (such as humerus, radius, tibia, femur), they comprise a diaphysis (shaft) and epiphyses at the distal and proximal ends, joining at the metaphysis. Lacunae Cavities containing bone cells (osteocytes) Arranged in concentric rings Lamellae. ): -Cancellous bone in the center; -Compact bone recoating all its peripheral surface. Bones have compact bone, spongy bone, and are remodeled through the actions of osteoblasts and osteoclasts. Developing tooth buds are enclosed in these grooves. Bone composition The endosteum refers to a layer of connective tissue that line the inner surfaces of bones including both the medullary (marrow) cavity of compact bone and the thin spicules or trabeculae of cancellous (spongy) bone. Physical Structure: Composed of cells and predominantly collagenous extracellular matrix (type I collagen) called osteoid which become mineralized giving bone rigidity and strength • Compact (cortical) bone • Dense rigid outer shell • Minimal gaps and spaces • Accounts for 80% of the total bone mass of an adult skeleton • INTERTADICULAR SEPTA: These are the thin plates of bone that separate the roots of multi-rooted teeth. Elastic B. Five types of bones in the human body • Flat bones – thin and generally curved, with two parallel layers of compact bones sandwiching a layer of spongy bone. Also called compact bone ; Forms a protective outer shell of bone . This tissue gives bones their smooth, white, and solid appearance, and accounts for 80% of the total bone mass of an adult skeleton. DEVELOPMENTAL ABNORMALITIES • Developmental abnormalities may affect isolated or multiple regions of the skeleton, or they may involve a specific tissue system; the latter are often hereditary. 19k views • 32 slides.

ALVEOLAR BONE (PROCESS) Definition: alveolar process is that part of maxilla and mandible that forms and supports the sockets of teeth. It identifies key features such as It describes the microscopic structure of compact and spongy bone, including osteons, central canals, lamellae, and trabeculae. HIGHER LEVEL Understand osteoblast role in bone growth. Types of bone tissue There are two types of bone tissue: a) compact bony tissue b) spongy bony tissue The names imply that the two types differ in density, or how tightly the tissue is packed together.

Bones form through two processes - intramembranous ossification where connective tissue is replaced with bone, and endochondral ossification where cartilage is replaced with bone. This lag between resorption and osteon ingrowth produce transient porosity in the compact bone visible radiographically for 3 months after fracture in humans. Michael Wrock Follow. Bone marrow is present in spongy bone but there is no medullary cavity like diaphysis of long bones Fig: 6. Porous (Spongy) bone Located in the ends of long bones.

The primary anatomical and functional unit of cancellous bone is It discusses the objectives, introduction, functions, embryology, gross anatomy including long bone structures, bone markings, microscopic anatomy, composition, classification, and formation, growth, and remodeling of bone. There are two main types of bone tissue: compact bone and spongy bone. Chapter 5 - Cartilage and Bone. Skull bones Ribs Sternum scapula. Gerlach’s 7th Grade Health Education. The cells (osteocytes) are embedded in the bone (lacunae) but they receive nourishment and they have connections with each other through the canaliculi.

Submit Search. 2010). Canaliculi, passageways in the matrix for cytoplasmic extensions between osteocytes Interstitial Lamellae, remnants of 7 Bone Structure Typical Four Layers Periosteum-covers bones Compact bone-lies beneath the periosteum Spongy bone (Cancellous)-lies beneath the compact bone Bone marrow-fills the gaps between the spongy bone Bone ppt - Download as a PDF or view online for free. has 2 layers of bone 2. Compact bone, microscopically, is made of numerous osteons, whereas spongy bone is Bone develops from cartilage through endochondral ossification and forms directly from mesenchymal tissue through intramembranous ossification. If the homogenized approximation is precise enough (and this is true for the mathematical theory of homogenization), it is then possible to simulate the macroscopic behavior from the microscopic mechanical Cells of Bone Osteoprogenitor cells ---- undifferentiated cells can divide to replace themselves & can become osteoblasts found in inner layer of periosteum and endosteum Osteoblasts--form matrix & collagen fibers but can’t divide Osteocytes ---mature cells that no longer secrete matrix Osteoclasts---- huge cells from fused monocytes (WBC There are two types of bone tissue: compact bone forming the outer walls and spongy bone in the interior. 8. Compact bone - circumferential lamellae outer (periosteal) Inner (endosteal) - interstitial lamellae - haversion system (osteon) 2. Cartilage is composed of cells, fibers, and a highly-hydrated ground substance. Flat bones consist of a layer of compact bone, interspersed with bone marrow (BM). Sesamoid bones develop within a tendon. Compact Bone 2. 731 views • 40 slides. Bone is derived from three embryonic sources. d. Mesenchymal progenitors aggregate into dense clusters and differentiate into chondrocytes to form cartilage by around E13.
