Chemical Composition of Bone Bone is a very hard material which is capable of bearing a large amount of weight and resisting tension and twisting forces. Therefore‚ this material is both flexible and hard. The hardness of bone is due to calcium deposits in the matrix while the flexibility comes from the organic material of the matrix. We can illustrate these facts by treating two bone samples by two different methods: 1. Soaking a bone in vinegar (dilute acetic acid) removes calcium

up of cartilage and bone. Both bone and cartilage are connective tissues‚ that is‚ they are composed of cells in a matrix with intracellular fibers. Just imagine connective tissue as a gelatin salad with grapes and coconut. The grapes would represent cells‚ the gelatin the support material for matrix‚ and the pieces of coconut the intracellular fibers. By changing the amounts of each ingredient and adding extra substances‚ we can produce a material that is very hard like bone and can withstand weight

Bones in our body are living tissue. They have their own blood vessels and are made of living cells‚ which help them to grow and to repair themselves. Every single person has a skeleton made up of many bones. These bones give your body structure‚ let you move in many ways‚ protect your internal organs‚ and more. As well‚ proteins‚ minerals and vitamins make up the bone. Bones have several parts‚ but are manily made out of calcium deposits. It takes around 20 years for our bones to completely

Salient Points Bone Formation * Bone formation termed ossification of calcification * Endochondral ossification – Forms all bones below skull (except clavicle) New bone forms from a hyaline cartilage model Bone tissue replaces the cartilage model Begins in the interior of each bone from an ossification center Ossification center – group of stem cells that transform into osteoblasts Long bones – ossification centers in the diaphysis and each epiphysis Short bones – one ossification

06/20/2013 “Body and Bones” The question for this assignment is what are the steps that the system goes through from childhood to adulthood to reach 206 bones? I don’t think there is an exact science on these steps really. When we are born we have about 270 bones in our body. These bones are soft and called cartilage. As we get older it gets hard and turns into bone. The bone in a baby’s body needs calcium which they get from their milk mainly for

Unit 5 Reading Guide Questions Which minerals are stored in bones? Triglycerides‚ calcium phosphate‚ and calcium hydroxide are all stored in the bones as mineral salts Which types of bones provides a large‚ flat surface area for muscle attachment? Flat bones such as the scapulae have large‚ flat surface area for muscle attachment. Describe the location‚ composition‚ and function of the epiphyseal plate. The epiphyseal plate is located in the metaphysis‚ and is composed of hyaline cartilage

~Cross-section of a bone~ Articular cartilage - is a white‚ smooth tissue which covers the ends of bones in joints. Periosteum - is a fibrous sheath that covers bones. It contains the blood vessels and nerves that provide nourishment and sensation to the bone. Cortical bone - forms the outer shell of all bone and also the shafts in long bones. Trabecular bone - is the tissue that makes up the interior of bones. Epiphyseal

is involved. 2. Bone tissue is the primary type involved 3. Connective tissue is the specific type of tissue involved 4. Osteoblasts are the specific types of cells that produce the normal microanatomy of the tissue. 5a. With ageing‚ bone mass decreases. This is espeically true of women following menopuase. Estrogen acts as a protector of bone by inhibiting the activity of osteoclasts. Once estrogen levels drop‚ after menopause‚ osteoclast activity increases. 5b. Bone mineral density (BMD)

Tissue Components Bone tissue is a type of connective tissue that contains lots of calcium and phosphorous salts. About 25% of bone tissue is water‚ another 25% is made up of protein fibers like collagen. The other 50% of bone tissue is a mixture of mineral salts‚ primarily calcium and phosphorous. ! !
