Case Study 2 Bone Tissue Questions and Answers

Task2: The main tissue types of the body and the role these play in two named organs of the body.

3. The radiologist reported signs of osteoporosis. Describe the characteristics of an osteoporotic femur as seen on an X-ray. (How does it differ in appearance from a normal femur?)

1. Describe bone physiology and the bone remodeling cycle. Be sure to emphasize the two types of bone tissue and the roles of osteoblasts and osteoclasts.

In this exercise, we will examine a fresh raw chicken bone to study bone structure.

How does spongy bone differ from compact bone? What differences did you see in the appearance of the spongy bone and compact bone? What color was the spongy bone?

It also protect soft internal organs for an example brain and heart from injury. Skeleton with muscle is strong bones that can enable the body to move freely. Individuals who is at increase risk for fractures may be difficult to heal because of the weakened bones. This can lead to loss of mobility, the inability to retain independent living and even death. Osteoporosis can gives a huge effect to human skeletal due to decreased mineralization of the bone. Human skeletal consist of two types of bones which is compact bones and spongy bones. Compact bones is a bone that has a solid outer surface while spongy bone is inner bone that less dense than compact bone which has many holes like sponge. A spongy bone does not have osteon.The matrix forms an open network of trabeculae. Healthy bone is dense enough to support and protect body and to handle stresses of movement and minor injuries while osteoporosis has abnormally thin bones with larger holes on spongy

j. Oral Calcium Supplements are used to prevent and treat low blood calcium levels for people that do not get enough

A long bone is composed of 6 main parts. The diaphysis, epiphyses, metaphyses, articular cartliage, the periosteum and medullary cavity. (Tortora and Derrickson, 2011).

For prevention, whether primary or tertiary, patients should be instructed to take 1000 mg (men) or 1200 mg (women) of calcium daily along with 800-1000 IU of vitamin D daily and participate in regular weight-bearing and muscle strengthening exercises. They should also be counseled to quit smoking and avoid excessive alcohol intake. M.L. is following all of these recommendations with the exception of inconsistent use of calcium supplements.

In conclusion, having an adequate intake of calcium in important for many functions of the body. Keeping a journal of daily food intake can help a person to be aware of missing nutrients that are important for proper functioning of the body. If a person is low on their calcium intake then eating or drinking foods with dairy will allow a person to increase their calcium, because dairy has the best bioavailability. However, lactose intolerant people may need to take a calcium supplement in order to get adequate amounts of calcium.

The FDA states women under 50 require about 1,000 mg of calcium per day. Women over 50 require about 1,200 per day. At one time, health experts believed that the best way to receive an adequate amount of calcium daily was through drinking several glasses of whole milk. Certainly, this is difficult for women that are lactose

One of the functions of calcium is bone and tooth formation. My low intake of calcium will affect my bone and toot formation.

Bones is a living tissue that contain a blood vessel and nerves. It capable of moulding itself when it damaged.

The skeletal system is made up of bones and joints. Bones are a dry dense tissue that is composed of calcium phosphorous and organic matter. The bones are protected and covered by a layer of fibrous connective tissue membrane called the periosteum (Brown, et al., 2015, p. 1547). There are two basic types of bone tissue: Compact Bone and Spongy Bone. Compact bones are dense smooth bones, while Spongy bones are composed of small needle-like pieces of bones and open space. Bones are then categorised according to the shape of the bone into four groups: long, short, flat and irregular. Long bones characteristically are typically longer then they are wide and generally have a shaft with heads at either ends e.g. the humerus. They are mainly compact bones. Short bones

Osseous tissue contains specialized cells, cell products, and a fluid matrix. The distinctive solid, stony nature of bone results from the deposition of calcium salts within the matrix. Crystals of calcium phosphate account for almost two-thirds of the weight of the bone. The majority of
