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

Introduction Mandible is the largest and strongest of the facial bones. Mandibular bone fracture is the tenth most common fracture in the human body and second most of the facial bones next only to nasal bones. Among the mandibular bone fractures‚ condylar region is the most frequent site accounting for about 25-35 %.1 Condylar fractures are usually the result of a direct blow to the chin or to the lateral side of the jaw caused by Road traffic accidents‚ violence‚ accidental falls and sporting injuries

THE FACIAL PART OF THE HEAD OPERATIONS ON THE HEAD The border between the head and neck is the line which is drawn along the inferior margin of the mandible‚ apex of the mastoid process‚ superior nuchal line to the external occipital protuberance and passes on to another side. The facial part is composed of the following regions: the orbital region‚ the oral cavity region (the region of the mouth)‚ nose region (region of the nose)‚ the lateral region and deep region of the face.

after the skin and muscle decomposed. He stated that the tape was placed there to hold the decomposing mandible in place (“Caylee Anthony’s Autopsy Was ‘Shoddy’”). Another theory is the mandible remained affixed to the body long enough for the mat to form because the skull was held in place by the swamp muck in which Caylee was buried. But‚ if the muck was indeed responsible for the mandible still being attached than it would have also held the duct tape in place unless the skull was moved significantly

A group of scientists lead by Biren Patel have recently found a partial mandible of an ancient primate related to lemurs. Scientists have named the new species Ramadapis sahnii and claim that it existed 11 to 14 million years ago‚ and is a member of the early primate family Sivaladapidae. Analysis of the jawbone shows that the species consumed leaves and was approximately the same size as a house cat‚ or to a modern day lemur. This discovery is important to the scientific community as with this discovery

Chimpanzees and bonobos are our closest living relative‚ sharing 98.8% DNA as well as anatomical and behavioural similarities‚ however we did not evolve from them or any other living primate‚ rather‚ we share a common ancestor from approximately 8 – 6 million years ago. (Smithsonian National Museum of Natural History‚ ND) Differences anatomically between chimpanzees and hominins can be identified through comparing their skulls. A broad overview of the differences in skulls between hominids and

unilaterally or bilaterally and most often on the premolar region. Mandibular tori are sharply demarcated anteriorly on periapical images and less dense as they extend posteriorly. There is no margin between the periphery of the torus and the surface of the mandible because the torus is continuous with the mandibular cortex. Torus mandibularis have been associated with age‚ gender and dental status; although both genetic and environmental factors may also play a role in the formation of torus‚ the masticatory
