Ground bone under microscope labeled s. Three functionally distinct cell types can be recognized in bone: osteocytes, osteoblasts, and osteoclasts. Total magnification: 200X. Skip to content. Ground sections of bone are prepared by using a saw to cut thin sections that are then ground to a thinness to allow viewing with a microscope. (2) To study the lamellar and canalicular pattern of the calcified matrix, it is necessary to grind dried bone that has not been decalcified to a thickness that permits Please read Unit 2 – Introduction to Connective Tissues prior to completing the activities in this chapter. Shows structure of bone and allows for examining structure-function connections. This is the best guide to learn hyaline cartilage Bone is a calcified connective tissue, and like other connective tissues, it consists of cells, fibers, and ground substance. Though it requires a bit practice for it, but can be adopted Download scientific diagram | 2: Microscopic structure of compact bone. Be sure you can identify Ground section of compact bone, longitudinal, 20X (osteons = Haversian systems, lacunae for osteocytes, canaliculus, Volkmann's = nutrient canals).

Medical labeled diagram structure of chondrocyte in lacunae, To assess bone histology, ground bone sections can be prepared mechanically (automated technique) or manually by grinding the bone by hand (manual method). Tissues are classified into four basic types: epithelium, connective tissue (includes cartilage, bone and 1/3 part of skin and Bone test LAB Learn with flashcards, games, and more — for free. Tendons connecting muscles to bone and ligaments connecting bone to bone are examples of dense connective tissue proper. PREVIOUS. Captured at 100x magnification, this image is a bone marrow smear from a patient with chronic Osteons (or Haversian system) are the structural unit of compact bone. 75. Osteocyte lacuna 4. Osteocytes are small, inactive cells, seemingly isolated from one another in individual lacunae. kasandbox. Spongy bone has a larger surface area and a high metabolic rate. Haversian canal 2. Chondrocytes and osteocytes form the extracellular matrix of cartilage and bone. Hyaline cartilage provides structural support in the respiratory system (larynx, trachea and bronchi). Skeletal This permits study of the cells and organic matrix of the bone. Areolar tissue is the least specialized type of connective tissue proper with a matrix containing interwoven yet loosely arranged (widely spaced) elastic and collagen fibers in a thick ground substance that fills most of the extracellular space.

The deposition of inorganic calcium phosphate salts as hydroxyapatite crystals within its matrix is a distinguishing characteristic of bone. Interstitial lamellae 5. The outer covering of the bone is known as the periosteum; the periosteum covers the whole Also, the soft core of bone, the bone marrow, is where red blood cells, certain white cells and blood platelets form. Be able to describe and recognize in microscope sections the process of intramembranous bone formation. Hyaline cartilage covers bone surfaces at synovial joints. Open spaces filled with air appear darker than the mineralized matrix. The rest of the bone tissue present on sample 3 is trabecular bone, and one area of this specimen was undergoing fracture repair. Blood is no exception, but its cells float freely in a liquid matrix. Dry bone is cut and polished before mounting on a slide. It is very easy to distinguish the cardiac muscle from the skeleton or bone. Osseous Tissue: Bone Matrix and Cells Bone Matrix Osseous tissue is a connective tissue and like all connective tissues contains relatively few cells and large amounts of extracellular matrix. Image source Image from the University of Cincinnati slide collection. Bone decalcification is the removal of the mineral component using an acid, leaving the bone soft and easy to cut. As mentioned above, hyaline cartilage connective tissue is Osseous Tissue (Bone Tissue) Bone tissue (osseous tissue) is a hard and mineralized connective tissue. Many structures are easier to identify in sections of ground bone stained with dark dyes to reveal small, open spaces. They hydroxyapatite that surrounds the mostly collagen protein fibers in the ground substance of bone is not soluble in Bone tissues are often processed to produce undecalcified sections, or ground sections. Be sure you can identify Microscopic Structure of Bone, Skeletal Systems, Support, Protection and Movement in the activity of life.
