Anatomical features Essay Example | Topics and Well Written Essays - 500 words

Anatomical features - Essay Example Radiometric analysis gives ‘Ardi’’s age as 4.4 million years, making her the oldest known hominid species to date. Ardi’s skeleton suggests a unique versatility and provides evidence of both biped and quadruped locomotion. The study of Ardi’s feet shows the markedly splayed big toe which facilitates the grasping of tree limbs, marking her as a quadruped in the trees. However, the presence of a small bone inside a foot tendon, which is absent in both chimps and gorillas, increases the rigidity of the big toe. This feature, in combination with other toe modification, promotes biped locomotion on the ground. Similarly, the pelvis shows both the large flaring upper bones which facilitate steady bipedality, and the lower pelvis which accommodates the huge hind limb muscles used in climbing like an ape. Again, unlike the strictly rigid wrist bones of chimps and gorillas, which are geared towards hanging from trees and knuckle-walking on the ground, Ardiâ⠂¬â„¢s highly flexible wrists and finger joints indicate that Ardi walked on her palms on tree limbs – like primitive apes. (Shreeve. October 1, 2009. National Geographic News). The most famous fossil remains of Australopithecus afarensis are the skeleton, "Lucy" found at Hadar, Ethopia, in 1974, the infant found at Dikika, Ethiopia, in 2006, and the 3.7 million years old footprints found in volcanic ash plus fossil bones found at Laetoli, Tanzania in 1978. The anatomical features in all these cases suggest that Australopithecus afarensis was capable of both bipedal and quadruped locomotion. Lucy’s long arm bones, and the ridge formed by the tendons attached to the humerus, indicate the strong chest and upper arm muscles required for tree climbing. However, her short, broad pelvis supported her upright body and her angled-in thigh bones maintained her weight directly above her knees – both optimum features for walking. Likewise, while Lucy’s compact,

Curriculum design and development Essay Example | Topics and Well Written Essays - 2500 words

Curriculum design and development - Essay Example It must be designed to meet specific goals that are evaluated towards setting a concrete foundation in knowledge, skills, understanding and values in all fields of work2. This document provides a proposal of changes and addition of some new information to the MAF of Orthodontic Therapy training. The new changes are meant to cater for new developments in technology and incorporate research based proven techniques that work to develop learners with capability of meeting the diversity seen in the current job market. As seen from the module descriptor, the MAF does not incorporate a relationship with any other module in the field of education. This means the entire course is just taught based on knowledge applied in the field without the consideration of other important courses that can add value to the professionalism of a student. The course descriptor lacks the element of diversity that is highly required in the current society that demands more than skills from individuals3. As seen from among the aims of the paper, the training offered aims to train individuals ready to accept professionalism through appreciating responsibility for contribution to high quality and effective care. However, the descriptor does not provide any measures to ensure that this aim is met. Relationship with other Modules In the proposed new model, there is proposal to create a relationship between this course and the study of professionalism and ethics. The expectations of the society are constantly changing and this necessitates that learners are subjected to a wide set of adaptive skills and values that will guide them to meeting these changing expectations. The integration of teaching ethics and codes of conduct will help students develop professional responsibility in all that they do4. By knowing the expectations of the people they will be serving, they will be able handle the needs of the people dependent on them such as pain management. Basically, a good curriculum should includ e the development of ethical behaviors among the trainees. This involves the willingness, capacity and determination to think and make judgments that will work for the good of the people they serve5. This will not be instilled through experience but needs to be incorporated in the curriculum design of the module of the institution for students to understand and act in accordance to ethical and moral principles6. This is the reason for proposing the inclusion of a relationship between Orthodontic training and Professional Ethics as relates to the field. A link must be created between this two learning areas to ensure students develop competency as they learn technical skills. Aims The aims of the course have been modified to incorporate the strategy of group work. This should be incorporated into the MAF to drive teaching and learning towards a cooperative learning system. This system of teaching will encourage small groups of students to work together in order to achieve a common go al. The curriculum must ensure to incorporate both the student and the faculty in the process of learning and sharing knowledge as this will prepare the students to doing the same in the future7. Knowledge sharing is an important aspect in the job field as it ensures the creation and distribution of new knowledge and this eventually helps ensure higher performance8. The instructors must understand how
