The three types of cartilages are hyaline cartilage, fibro cartilage, and elastic cartilage. Bone Markings. This makes up critically important tendons (connects muscle to bone) and ligaments (connects bones to bones). It is what gives the bone strength, as well as its smooth, white, solid appearance. Viele übersetzte Beispielsätze mit "spongy bone" – Deutsch-Englisch Wörterbuch und Suchmaschine für Millionen von Deutsch-Übersetzungen. Each stride and jump sends tiny shock waves through the skeletal system, and spongy bones help to … The greater surface area also makes it suitable for metabolic activities such as the exchange of calcium ions. Spongy bone is softer and weaker than compact bone, but is also more flexible. Spongy bone is found in the heads. Bone is hard and many of its functions depend on that characteristic hardness. Compact (cortical) bone: A hard outer layer that is dense, strong, and durable. The difference between spongy and compact bones is given below in a tabular column. Primary location is also a consideration. Structure. The outer surfaces of most bones are generally made up of compact bone, and shafts of long bones, such as femurs, are, too. As its name suggests, spongy bone is porous like a sponge, containing an irregular network of spaces. Location. Their surfaces intended for joining with adjacent bones are covered with articular cartilage. Spongy Bone: Spongy bones are softer and more porous. Histology and Cell Biology: An Introduction to Pathology, A.L. Perfekte Spongy Bone Stock-Fotos und -Bilder sowie aktuelle Editorial-Aufnahmen von Getty Images. Spongy bones essentially act as shock absorbers; the human body endures high volumes of impacts each day through movements such as walking, skiing, running and jumping. The advantage of the epiphysis being formed of spongy bone is that the bone would still be strong but lightweight. With lightweight bones it would be an advantage for a runner, boater or gymnast, etc. Compact and Spongy Bone. describes the bone markings, which are illustrated in ().There are three general classes of bone markings: (1) articulations, (2) projections, and (3) holes. Compact Bone: Compact bones occur in the inner surface of a bone. Describe spongy (cancellous) bone tissue location and function. The bone ends – epiphyses, epiphyses, – are somewhat thickened. It makes up about 20 percent of the adult skeleton and is found at the ends of long bones, in the cores of vertebrae, and in the pelvis, as it supports shifts in weight distribution. Hyoid bone fractures occur more frequently in young individuals, and in men more than in women 6). describes the bone markings, which are illustrated in ().There are three general classes of bone markings: (1) articulations, (2) projections, and (3) holes. Compact bone is the outside of bones. Long bones are dense hard bones that provide strength, structure and mobility. Spongy bone. Types Of Bones In The Human Body - Long Bones - Short Bones - Flat Bones - Irregular Bones - Duration: 1:40. Trabeculae Function.

FIGURE 5.1 The structure of bone GOODMC05_9996_82-96 10/10/06 12:18 PM Page 83 . They make up the long bones in the body. Spongy bone (also known as trabecular bone) is 50 to 90 percent porous and appears as a lattice-like structure under a microscope. And as we can remember back to our basic functions of the skeletal system. This makes spongy bone much less dense than compact bone. It is made of tightly packed cells so it is very, very dense. Spongy bone isn’t as dense as compact bone and looks very much like a honeycomb. Spongy bone located between two layers of compact bone. Collectively allow weight transfer, source of quick bone absoprtion and formation. In adults, bony matrix is lamellar (layered). Hyoid bone fracture accounts for 0.002 % of all fractures 4), but a higher incidence of 1.15 % was found by Stiebler and Maxeine 5). Bone in human and other mammal bodies is generally classified into two types 1: Cortical bone, also known as compact bone and 2) Trabecular bone, also known as cancellous or spongy bone. Spongy Bone: Spongy bones form major parts of the short bones such as wrists and ankles. Spongy bone is typically found at the epiphysis (the ends) of a long bone. Compact bone (which is also referred to as "cortical bone") makes up the outer layer of most bones. What is Bone – Definition, Characteristics, Function 2. Cortical bone is much denser with a porosity ranging between 5% and 10%. This makes up critically important tendons (connects muscle to bone) in one direction. Compare and contrast compact bone and spongy bone regarding their location, bone cells, function and structure. Spongy and compact bones are two basic structural bone types. Compact (dense) bone Shaft of long bone 2. These trabeculae are located in between red bone marrow. Instead, the lacunae and osteocytes are found in a lattice-like network of matrix spikes called trabeculae (singular = trabecula) (Figure 6.11). Small, thin, short bony tissues. These two types are classified as on the basis of porosity and the unit microstructure. and find homework help for other Science questions at eNotes Bone Markings. Compact Bone: Compact bones are hard. Describe the location and function of the osteon systems. The surface features of bones vary considerably, depending on the function and location in the body. Spongy (trabecular, cancellous) bone External layer of all bones Select ALL choices that apply. 1. Trabeculae Structure. Spongy bone has a greater surface area than cortical bone but makes up only 20 percent of bone mass. Dense regular CT referred to as white fibrous tissue provides resistance against forces in one direction. The surface features of bones vary considerably, depending on the function and location in the body. Contents. Spongy bone is found throughout the body and in virtually every long bone, short bone and sesamoid or circular bone. by Microb Life. The formation of osseous tissue in areas outside of bone is called _____ ossification. Spongy bone is prominent in areas of bones that are not heavily stressed or where stresses arrive from many directions. 3. Compact bones are also called cortical bones, which contain osteons or Haversian systems. It makes up around 80 percent of adult bone mass. Table 6.3. Spongy. The epiphyses of bones, such as the neck of the femur, are subject to stress from many directions. Most bones contain compact and spongy osseous tissue, but their distribution and concentration vary based on the bone’s overall function. On the inside, the epiphysises consist of spongy bone – substantia spongiosa, and on the outside there is a thin layer of compact bone – substantia compacta. Compact Bone: Compact bones … No osteons. Table 6.3 reviews the bone cells, their functions, and locations. Spongy Bone Location. Spongy and compact bone have the same extracellular matrix and the same cells, (osteoclasts, osteocytes, and osteoblasts) they are just organized differently. Cartilages act as shock absorbers. Center of diaphysis and epiphysis of long bones and center of most bones. 4.

Spongy vs Compact Bones Compare and contrast compact and spongy bone; Identify the structures that compose compact and spongy bone; Describe how bones are nourished and innervated ; Bone tissue (osseous tissue) differs greatly from other tissues in the body. There are two types of bones known as compact bone and spongy bone. 2. Ectopic. They can be found in the ear, nose, larynx, trachea, ribs, and joints. Enlarged chondrocytes die and the cartilage matrix is calcified. Within the diaphysis, the medullary cavity is located. Cancellous bone, also called trabecular or spongy bone, is the internal tissue of the skeletal bone and is an open cell porous network. As discussed above, compact bone indicates the outer layer or shaft of bones. Spongy bone is usually located at the ends of the long bones (the epiphysis), with the harder compact bone surrounding it. Compact bone is located on the outer surface of the bone. Spongy Bone: Spongy bones occur in the outer layers of a bone.
