extinct. The pre-sapiens hypothesis theory is mainly derived from European fossil record. The pre-sapiens hypothesis was believed to prove that the Piltdown (i.e., Eoanthropus dawsoni, a species that was made from a human cranium that was attached to a mandible of an ape) was between Homo erectus and Homo sapiens and that Neanderthals…

When lined up in a row, the skulls of a chimpanzee, neanderthal, and homo sapien contain the same basic structure with variations in the cranium, maxilla, and mandible. John Scopes, a Tennessee substitute teacher, was placed on trial in 1925 for violating the Butler Act. He taught that theory of evolution, that man is descended from the primate family. This was illegal in Tennessee because the Butler Act state anything that denied the story of Creationism forbidden to be taught in public…

Bone Types Long Bones: Long bones are dense, hard bones that provide strength stability and mobility. For example the femur is a long bone. A long bone has two ends and a shaft. In the finger some bones are long bones, due to the shape of the bones despite them being short. http://umm.edu/health/medical/ency/articles/long-bones Short Bones: Short bones are as long as they are wide. They’re function of them is to provide stability and little movement. http://www.teachpe.com/anatomy/types_of_bones…

Muscles and skin cover these bones, and this cover is called the scalp. Fourteen bones in the anterior region of the skull form the face. These bones provide structure for the face and cavities for nose, eyes and mouth. Also, these bones allow the mandible to move. The poromandibular joint allows the person to open and close the mouth and provides movement to the chin and jaw, these are actions used for speaking and chewing. Also, the muscles of the scalp, face and neck allow…

al 1977). Opdebeeck et al 1978 analysed and compared linear and angular measurements for short face and long face syndrome and concluded that the characteristics of the long face and short face syndrome group can be explained by rotation of the mandible in concert with the movement of hyoid, tongue, pharynx and cervical spine. (Bibby et al, 1981) proposed new technique in which they introduced the ‘hyoid triangle’ taking Retrognathion (RGn), hyoidale (H) and third cervical vertebra (C3). This…

Got milk? Hopefully so because osteoporosis is the most common type of bone disease, affecting over 200 million people worldwide. It involves the loss of bone mass and mineral content which causes the bones to become fragile and brittle. This leads to a higher risk of fractures, or breaks and cracks, than in normal bone. Literally, the word “osteoporosis” translates to “porous bones,” and occurs when excessive bone is lost, inadequate bone is produced, or a combination of both. Living with…

oddly-shaped beaks are specially adapted to separate mud and silt from the food they consume, and are uniquely used upside-down. The filtering of food items is assisted by hairy structures called lamellae (a thin layer of plate like tissue) which line the mandibles, and the large rough-surfaced tongue. It is the shellfish and shrimps which flamingos eat which give them their distinctive pink color, otherwise they would be white. Which is the color they are born with, a whitish grayish color. It…

Introduction Sufficient analgesia is essential for canine patients undergoing oral surgery, such as dental extractions and orthopaedic procedures involving the maxilla and/or mandible. These procedures produce strong sensory stimulation that impact on general anaesthetic requirements and produce post-operative pain (Woodward 2008). Providing multimodal analgesia for our patients is beneficial for several reasons. From a clinical standpoint, pre-operative local nerve blocks decrease the level of…

3. A. Cranial nerve involvement can be broken down into two portions. The anterior 2/3 of the tongue are innervated by the Chorda Tympani branch of the Facial nerve which is carried by the lingual nerve which branches off the mandibular branch of the Trigeminal nerve. Sensory component of the anterior 2/3 is maintained by the lingual nerve. The posterior 1/3 of the tongue is innervated by the glossopharyngeal nerve which supplies both sensory and taste. B. The human tongue contains multiple…
