How does a chicken wing compare to a human arm
A chicken wing relates to the human arm because they share bunch of similarities including structures, and systems. While conducting research, I found similarities in bone structure. I found that a chicken has an ulna, radius, and a humorous. There also connected in the same way and act kind of in the same way. The scientific principle that reinforces the claim is, bone cells make up bone tissue which make up bones. In relations to the dissection, the chicken has muscles and tendons also relating to humans. The chicken also uses the muscles to move relating to humans. Muscles and tendons are both made up of their own cells, making the tissue creating the tissues form. For instance, ligament and
Fluids drain from the carcass before moving on to the rubber fingers. The array of fingers makes quick work of removing the feathers, leaving the bird bare. Finally, the bird’s innards are removed in what is a mostly mechanical process. Machines then spray an antimicrobial rinse on the chickens before food safety inspectors check each bird for broken bones, abrasions and bacterial infections. To ensure food safety, every day, workers thoroughly sanitize the entire processing facility with hot water and food safe cleaning agents. The poultry leaves the first facility resembling the oven-ready bird that is familiar to most U.S.
With Particular Reference to the Relationships Between Men and Women, Compare and Contrast the Two Short Stories Turned and The Withered Arm. The two short stories by Thomas Hardy and Charlotte Perkins Gilman both share similarities in plot, characters and the relationships held by men and women. They both show, in a cyclical structure, the betrayal of men and the jealously held between people, although Gilman takes a more feminist view, largely due to the difference in era of the two short stories. They simultaneously show the strengths and weaknesses of women without men and the role which men have upon their lives. Hardy's era leads him to incorporate ideas of witchcraft and the paranormal and crime also proceeds the beginning of each story with two women becoming illegitimately pregnant.
Repair after a muscle is damaged happens through the division of certain cells who then fuse to existing, undamaged muscle fibers to correct the damage. Different muscle types take different amounts of time to heal and regenerate after it has been damaged. Smooth muscle cells can regenerate with the greatest capacity due to their ability to divide and create many more cells to help out. While cardiac muscle cells hardly regenerate at all due to the lack of specialized cells that aid in repair and regeneration. In skeletal muscle, satellite cells aid in helping restoration after injury. Along with muscles, tendons are very important structures within the human body, and they to can be damaged. However, tendon repair involves fibroblast cells cross-linking collagen fibers that aid in not only reinforcing structural support, but also mechanical support as well (“Understanding Tendon Injury,” 2005). While quite different from muscle repair, tendon repair involves the similarity of reestablishing d...
According to National Geographic, scientists have sequenced the genome factor of the chimpanzee and found that humans are 98.5% similar to the ape species. The chimpanzee is our closest relative in the animal kingdom; however, some people are not aware of our resembling traits with chimpanzees. Jane Goodall’s, In the Shadow of Man, describes some similar traits humans and chimpanzees have such as their facial expressions and emotions, use of tools, and diet.
As you can see by the diagram, the muscles cover the entire body as does the integumentary system. They are responsible for movement. They are attached to the bones (skeletal system) and there are nearly 700 different ones. Each is made up of the muscle tissue, blood vessels, tendons and nerves. Each has a specific purpose. For example, the leg muscles assist in moving and bending the legs. The muscles make up nearly half of a person’s total body weight.
The human body is made up of 12 different systems. Each system has a separate function while some do work together. One system is called skeletal system which is to serve as a support the body, mineral storage, energy storage (fat), blood cell production, movement (leverage), and protect the internal organs. (Martini, 112). With the help of the muscular system, it keeps us moving and makes us to do tasks that we don’t think about like swinging the arms while running. The average adult skeleton has 206 bones that are joined together by ligaments (bone to bone) and tendons (muscles to bone) to make a protective framework for the tissues and muscles. The vital organs are also protected by the skeleton, brain is covered with skull just like heart
A chicken wing does in fact, compare to a human arm in a variety of ways. To begin, a major similarity between the human arm and the chicken wing, is the bone structure. From the research we did in our dissection, and the image on google classroom, the humerus, the radius, and the ulna are the three bones that form the major bone structure of the chicken wing, and the human arm. Furthermore, two specific muscles in the human arm and the chicken wing are shared. The research from our dissection notes helped us notice that these two muscles are the flexor, and the extensor, the flexor is the muscle that makes your arm flex, by pulling in, and the extensor is the muscle that makes your arm stretch out to the full length. Finally, the nerves are
Skeletal and smooth muscle cells show a number of similarities however they also display many differences. These similarities and differences can be seen through observing the structure and appearance of these cells, their control mechanisms and the ways in which they contract.
In the muscular system the main differences between minks and humans are mostly the size and shape of each muscle. However, for example the temporalis differs in that it has different locations within the mink and human. In minks the temporalis is located on the dorsal side of the skull while, in humans it is located on the later side. Also the romboideus complex muscles differ in location as well. In humans these muscles are located in the upper section of the dorsal side while, in minks they are found closer to the neck. Another example of differing locations if that of the levator scapulae. Though the functions are the same which is to elevate the scapulae and shoulders, in humans it is located in the upper section of the dorsal side of the body behind the neck. In minks the levator scapulae is located lower down the back. The main similarities of the muscular system between minks and humans are both the name and functions of the muscles. For instance, the masseter elevates the mandible which helps in raising the lower jaw to close. Also there are the obliques and transversus abdominis that encloses the abdomen while the diaphragm separates the thoracic and pelvic cavities. The gastrocnemius muscles also have similar functions between the mink and humans which are the plantar flexion of the foot at the ankle and the flexion of the leg at the knee joint.
Through time, there has been a significant decrease in the number of bones through fusion, or loss of individual bones (“Evolution of Birds”). The loss in these bones result in a “hollow construction of the skeleton,” as well as a reduction in the availability movable joints. Though this seems like it should not benefit the bird, it is actually better adapted as a framework of a “flying machine.” The clavicle of birds is used and near it is a keeled sternum that the flight muscles attach to. The skull of a bird is lightweight and mostly composed of the protein keratin. Without teeth present, the jaw has also become light weight, all aiding in its ability to achieve the best possible flight. The changing in structure of the physical bird and functions of each their bones have aided in their diversification and ability to thrive as the modern bird that we know
The skeletal system is an anatomical body system which consists of all the bones and joints in our bodies. In total, an adult body entails 206 distinct bones, arranged in the axial skeleton (80) and the appendicular skeleton (126). The latter division has bones in the limbs, pelvic girdle and the shoulder girdle, whilst the rest of the bones belong to the axial division. It’s a very important system therefore it has a few main functions. The most obvious is that it gives the body its rigid shape, which makes it relevant to other body functions like breathing, which is helped by the rib cage expanding to accommodate the movement of the lungs. Other functions include support to ensure that organs
The skeletal system is composed of two hundred and six bones in the human body. Functions such as the tendons, cartilage, and ligaments connect the bones and tissues together. Bone tissues make up about 18% of the weight of the human body. There are two types of tissue inside the bones. They consist of; compact bone and spongy bone. First, compact bone depicts the main shaft of long bones in the human body such as the arms and legs. Its tissue is dense and hard and it also makes up the outer layer of most bones in our body. Meanwhile, spongy bone tissue is made up of smaller plates occupied with red bone marrow. Mostly, it is found at the ends of long bones such as the head of the femur.
The origin of birds is one of the great mysteries in biology. Birds are dramatically different from all other living creatures. Feathers, toothless beaks, hollow bones, perching feet, wishbones, deep breastbones, and stump-like tailbones are only part of the combination of features that no other living animal has in common with them (Padian and Chiappe 1998).
The first step was to obtain the White Rat and to tie it in the supine position, anterior surface facing up in side the dissection pan. To tie the animal, we used butcher’s twine and secured the front and hinds legs using a “lasso” technique, careful not touch the sharp claws. To make the first insicion I had to locate the Xifoid Process of the rat (distal aspect of the sternum). Once I had located the Xifoid Process, I had to use forceps to pull the skin of the animal’s abdomen up and use the scissors to cut. The first incision is made from stem to sternum, cutting through the errectos abdomen muscle down to the groin. The second incision ion is perpendicular to the first below the diaphragm. Because of this technique we were able to open the abdominal cavity first. The third and forth incisions were made bilaterally above the legs. The last two incisions were made in upside down “V” shape on the collarbone, to expose the thoracic cavity. This dissection was both sharp, because of the use of the scissors and scapel and blunt because of the use of the probe and forceps to move organs and skin to expose other organs not yet identified.
It is like a bone however, the bone is more rigid. It allows some movement as well as providing stability which is better than the actual muscle. The material with a specialised structure is created by cells, which are called Chondroplasty. This is also important as it helps movement and reduce friction. There’s a large about of flexibility in the tissue as they are elastic fibre which, give a large amount of strength.
