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)

A&P I: Bone Tissue Study Packet This activity is optional and is meant to help you study. The purpose of this activity is to get you looking through your notes and thinking about the testable material. An answer key is not available‚ so please contact Dr. Greco if you have any issues. Feel free to send this packet to Dr. Greco for feedback. For question 1 & 2‚ what bone region is being identified?: 1.__Epipysis_______________________________ 2.__Diaphysis(shaft)_____________________________

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

Bone is a unique combination of organic and inorganic components. * Two levels of study * Macroscopic: gross morphological features * Microscopic: aka histology‚ study of tissues * Two levels of histology * Cellular * Molecular Bone Biology – Macroscopic * All bone in adult skeleton is

Cartilage and bone are both stiff connective tissues which form an essential structural component of the body of animal organisms‚ including human beings. However‚ they are also quite different in both composition and function. Bones are extremely hard‚ dense tissue which provide a supportive frame for the body ‚ as well as serving as production and storage centers for cells and minerals‚ whereas cartilage is a more flexible tissue found in more specific locations of the body‚ essentially midway

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

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
