171 Izy Grooms Osmosis: Marissa‚ Jeremy‚ and Eleanor Question on front of packet Calcium helps to keep bones strong but just drinking milk doesn’t mean that you won’t get osteoporosis. You may be genetically inclined to get it even though you drink milk every day. There are also many other things that contribute to getting osteoporosis‚ like not eating enough calcium‚ doing steroids causes bones to become weak and look like sponges when looking at it under a microscope. Scenarios A‚B‚ and C help to

Growth of Bones By: Asmaa Mohamed Bahaa ID: 2012189 Report on Bones’ Growth‚ Page 1 Assignment 1 BONE TISSUE ! 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. ! !

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

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

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)

Bone functions as support and protection for the body as most of us may know. However‚ bones also function as a storage place for many essential life sustaining minerals. Calcium is the main mineral that bone is primarily composed of‚ and is very essential for other important body systems. When calcium levels are not adequate in the body from diet alone the body taps into the bones to get the calcium that cells organs nerves and muscles need. When the amounts of calcium are enough for the body‚ then
