Insects Project 1. Orders Lepidoptera- Examples of this order found in Australia would be Abantiades Barcas‚ Barbifrontia and Callionyma sarcodes. The members of this order have 4 wings‚ which are all completely covered in small scales. All the adults in the Lepidoptera family start off as a caterpillar‚ which resembles a worm‚and grow up to be either a moth or a butterfly. The butterflies have very thin antennas and tend to fly during the day‚ while the moths have feathery antennas and are

Bone‚ in the human body‚ performs a number of mechanical and physiological functions‚ including mechanical support‚ movement and protection of vital organs. It is a complex tissue that undergoes constant repair and remodelling to its micro-architecture caused as a result of biomechanical forces imparting trauma and homeostatic insults. [1] The basic unit of bone is an osteon‚ which is made up of concentric lamellae of compact bone surrounded by a Haversian canal. There are two components to bone

Introduction: Occlusal vertical dimension (VD) can be defined as the distance measured between two points when the occluding members are in contact or it can be defined as the distance between any two points measured in the maxilla and the mandible when the teeth are in maximum contact. A loss of OVD can significantly have in impact on the function‚ aesthetics and comfort of the patient. Comprehension of altering vertical dimensional effects on facial aesthetics‚ diagnose of the causative factors

Maceration Techniques and Methods The interest in maceration‚ in the anthropological perspective‚ began in the 19th century. Over the following century the largest ambitious endeavor was the maceration of thousands of individuals‚ this collection is known as the Hamann-Todd Collection (Dawnie 11). Maceration according to the Merriam-Webster Dictionary is‚ “to cause to become soft or separated into constituent elements by or as if by steeping in fluid”. Maceration is a form of controlled putrefaction

Project 1.2.3: Bone Detectives Introduction When we think of bones‚ we most often think of the way in which these hard structures support the body‚ how they work with muscles to produce movement and how they protect our internal organs. But the 206 bones of the human skeleton can also tell a story. The specific structure of your bones reveals information about your gender‚ your height‚ your age and even your ethnicity. These biological clues are often the first pieces of evidence scientists

Unit 3: Paleoanthropology and the Fossil Record Paleoanthropology * The study of human evolution‚ the hominid fossils‚ and their relations to each other and modern humans. The study of the fossil record‚ the study of the relationships among the fossils to themselves and to us. * There is nothing outside Africa that is even in the running to be a potential human ancestor * The most fossils are found in East Africa in the Rift valley‚ several in South Africa‚ and a few in Central Africa
