The appendicular skeleton is the part of the body that includes the upper and lower limbs along with the pectoral girdle and the pelvic girdle. The upper limb is attached to the trunk by the pectoral girdle; the pectoral girdle consists of the clavicle and the scapula. The clavicle is a boned strap which joins the scapula at the acromioclavicular joint and the axial skeleton at the sternum to form the sternoclavicular joint. This is the only bone attachment of the upper limb with the axial skeleton. The scapula is a large, flat triangular bone that is suspended on the posterior wall of the ribcage by its muscular attachments, it is characterised by several markings and processes; the spine of the scapula is a prominent ridge that arches forward to an anterially as the acromion. The acromion is a prominent process that articulates with the clavicle at the acromioclavicular joint. The coracoid process is located inferior to the dystole end of the clavicle and it is the sight of the muscular origin of the short process of the bicep, the position between the coracoid process and the acromion is the glenoid cavity; this is the depression where the head of the humerus articulates with the scapula and the joint is known as the glenohumeral joint. The humerus is the long bone of the arm; it has a rounded head and two dystole pretrubances, the medial and lateral epicondyles. At the elbow joint both the lateral bone of the forearm, the radius and the medial bone of the forearm, the ulner, articulate with the humerus and with each other. In the posterior side of the elbow joint, the proximal end of the ulner is larger than the radius, this process is known as the olecranon. At the wrist joint, the dystole ends of the radius and the ulner a... ... middle of paper ... ...neck region which joins the head to the shaft of the femur, the greater and lesser trochanters of the femur, the shaft of the femur expands distally to form the medial and lateral condyles of the femur; at the dystole end of the femur is found the knee joint. The knee joint is often referred to as a table joint, the medial and lateral condyles rest on top of the tibia. The small bone located anterior to the knee joint is referred to as the patella. In the leg is found two long bones, these are known as the tibia and fibula. The bones of the foot include the tarsal bones which form the ankle joint, the metatarsals and the phalanges. The most important of the tarsal bones are the talus bone which forms a joint with the tibia and fibula and the calcaneus which forms an attachment to the muscles of the calf via the calcaneus tendons also referred to as Achilles tendons
In both species, deltoid muscles allow for the abduction of the humerus. The next two muscles are the biceps brachii and its opposing muscle the triceps brachii. The biceps brachii consists of two heads, which arise from the scapula and join to form a single muscle that ends upon the upper forearm. The most important functions of the biceps brachii are the supination of the forearm and the flexing of the elbow. The triceps brachii on the other hand extends the forearm in both minks and humans and has three heads as opposed to two in its antagonist biceps brachii (Scott).
The book I read this month was Sammy Keyes and the Skeleton Man. This is the second book in the Sammy Keyes collections by Wendelin Van Draanen. This book is a mystery and has 171 pages.
Selection of Book: There were numerous purposes and objectives as to why I chose to read this particular anthropology manuscript of all the various other options available. For one, I selected this book initially due to the title of the book. “Dancing Skeleton” was the portion of the title that primarily stuck out to me, and made me imagine African children – who we see on commercials all the time in third world countries, which tend to look malnourished all throughout their adolescents – dancing around with skin-wrapped skeletal bones. Personally, for me, seeing children suffering from malnourishment and starvation must be one of the most unbearably agonizing pains a child can go through, not to mention the suffering of a mother having to watching her child gradually starve to death. I was additionally very much interested in understanding precisely what other individuals in different parts of the world and specifically Mali, are lacking that is affecting their health and well-being so noticeably. Furthermore, I was especially interested is reading informal stories and accounts through the eyes of the author about conducting specified field research on infant feeding and the importance of children
“This is my lab and what we do is study bones,” states Kari Bruwelheide in her video entitled “30,000 Skeletons”. Of the three resources that we were provided, “Puzzles of the Chesapeake” by Sally Walker, “Forensic Anthropology” by an unknown author, and “30,000 Skeletons” by Smithsonian Education presented by Kari Bruwelheide, the resource “30,000 Skeletons” is by far the best at explaining the role of an anthropologist. It is unbeatable because it is a video rather than just written words, and Kari Bruwelheide has personal experience in being a forensic anthropologist. A forensic anthropologist is a scientist that studies human remains, or in another word, skeletons, to try to find out information about the past.
The Farming of Bones by Edwidge Danticat Talking about the culture brought throughout this book, you’re looking at Latin American culture, specifically the Dominican/Haitian cultures. As I read this book, beyond the many numerous ways she worded her sentences and how the characters spoke, they often spoke with a definant difference than you would hear here in common U.S. language. They would constantly use inferences to what they were talking about, rather than being direct to what they were saying. Things like, “they say we are the burnt crud at the bottom of the pot.” –Amabelle, this is Amabelle talking to her lover, Sebastian, about how there’s talk about the field workers and the housemaids to the Dominicans, and them being “nothing”, inferring that they are poorer than the Dominicans.
C. As the body of calcaneum progresses proximally and lateral, it causes the superolateral fragment to rotate medially and to impact into spongy calcaneous bone which sweeps out the sheared off lateral wall fragment and results in commounited fragments impinging into the peronal tendon space against fibula.
The skull is what holds the mind; it is the cavity that holds our perception of the world, society, and our beliefs. By the power that we have to produce creative thought through our mind and thus our skulls, we are able to think, connive, and eventually die. In “Upon A Deadman’s Head,” John Skelton shows a man’s progression of thought when he faces his mortality by seeing a skull. The character’s thought process is indicated by Skelton’s use of imagery, rhythm, word choice and address, motifs, and the presence of the skull to the character and Skelton’s reader. As the poem progresses, the man tries to find ways to escape the literal death he sees in the skull through spiritual salvation. Skelton uses the character’s denial of his literal death to provide a lesson for the reader: be accountable for their earthly actions and accept their inevitable death.
The surfaces of the joint are organised to allow only back and forth motion such as bending and straightening. This type of joint can be found between your upper arm and your lower arm, in the elbow. This type of joint is incredibly important as it allows an up and down movement, without this type of joint, we wouldn’t be able to move our arm up and down. Muscles are attached to this type of joint by tendons to allow it to contract and relax and be able to move the bone within this joint. Ligaments attach the bones in a hinge joint together, for example, the humerus and the tibia are joined by ligaments but they also have antagonist muscle pairs attached to them by tendons which allow the bone to move by contraction and relaxation of the muscles.
They also differ in the types of bones that make up their individual skeletons. Axial skeleton consists of bones from the skull, vertebral column, ribs and sternum and the appendicular skeleton consists of bones from the limbs, pelvis girdle, and pectoral girdle. The skeletal system is crucial for the human body to continue functioning and maintaining homeostasis.
The skeletal system is composed of many bones, joints, cartilage, ligaments, and tendons. The key functions of the skeletal system are to supply a supportive frame for the body, to shield the internal organs such as the heart and lungs. Providing attachment points for muscles is also another function as this enables the parts of the animal to have good locomotion, the long bones produce bone marrow. However, for this report, I will be concentrating more on the joints of the canine skeletal system. The joints are the articular exteriors at the end of the bones, they are shielded by a coating of cartilage. There are three main types of joints within the canine skeletal system they consist of the fibrous joints, these do not allow any movement
The skeleton is divided into two major parts: the axial skeleton and the appendicular skeleton. The axial skeleton forms the central axis of the body and includes skull, spine, ribs, and sternum. The appendicular skeleton includes the appendages, which are the shoulders, arms, hips, and legs.
The skeletal system is made of all the bones, connective tissues and joints in the body. Bones, cartilage are some of the bones that make up the Skeletal system. The Skeletal system helps perform important everyday functions, for example; support, movement and protection, etc. The skeletal system helps form blood cells. The skeletal system helps store calcium and phosphorus, which is important and beneficial to the other functions in the body.
The fibula is a leg bone located on the lateral side of the tibia, with which it is connected above and below. It is the smaller of the two bones, and the slenderest of all the long bones, and plays a significant role in stabilizing the ankle and supporting the muscles of the lower leg. The fibula is the smaller, non-weight bearing, of the two bones in the lower leg, while the tibia is the larger, weight bearing bone. The fibula and tibia moves very little relative to each other and the joints that it forms contribute significantly to the function of the lower leg. The joint it forms permit the fibula to adjust its position relative to the tibia, increasing the range of motion of the ankle. Fibular fractures are not often a severe injury, because the bone is supports only about 17% of the body weight.
The human foot is an incredibly complex part of the body, it is made up of twenty-six bones which is fully twenty-five percent of the bones in the entire body. The structure of the forefoot includes the five metatarsal bones and the phalanges. The metatarsal bones are for forward movement and provides attachment for several tendons. The phalanges, also known as the toes, movement take place in the joints. The foot movement only has two movements; inversion and eversion. All the joints in the hindfoot and midfoot contributes to these complex movements. The foot has two significant functions: weight bearing and impulsion, which both requires a high degree of stability. The foot must also be flexible so it is able to adapt to uneven surfaces. The various bones and joints of the foot are what allows the foot to be flexible. In order for the foot to be able to support any weight the various of bones must form an arch. The foot has three arches that are maintain by the shape of the bones and by the ligaments. The arches are supported by the muscles and tendons. A foot is a strong, flexible, and durable it allows us to daily activities as we please while carrying all the
There is two divisions of the bones, the axial skeleton and the appendicular skeleton. The axial skeleton consists of 80 bones which include the skull, vertebral column, ribs and sternum. The skull considts of 22 bones. The cranium which cover the brain are made up of 8 bones and the facial is made up of 14 bones.
