Cranial capacity

two feet. Variables: Dependent: Determine whether if the organism is bipedalism, prognathism and measure the cranial capacity. Independent: The skull we choose to test on Materials: A protractor A ruler A calculator Skulls of human’s ancestors Sliding calipers Procedures: Read the direction carefully. Prepare all the materials that you needed. Read carefully the number and match it with the name of each skull. Use to ruler to measure the opisthocranion - opisthion distance, be sure to use the centimeter side. Start off with a “0” at f the opisthion and read the measure at the opisthocranion then record it. Measure the distance between the opisthocranion to the orale by using the sliding calipers and record it. Measure the maxillary angle with a protractor and record it. Also use the sliding calipers to measure the height of the skull, from the top to the bottom of the skull then record the measures Use the same tool to measure the width, be sure to choose the biggest place of the skull’s width and record the measures Put the sliding calipers from the forehead to the very back of the skull to measure the length; carefully record the result. Calculate the opisthion index using the formula (A/B) x 100; “A” is the distance from the opisthocranion to the opisthion; “B” is the distance between the opisthocranion - orale. Use the formula (LxWxH)*.5236 to find the cranial capacity; “H” is the height; “W” is the width; and “L” is the length. Record the result. Data table and…

THE SEVENTH CRANIAL NERVE Testing the Function of the Facial Nerve VII Anatomy & Physiology 203 November 15, 2014 Introduction: The facial nerve is the seventh cranial nerve of the peripheral nervous system that is the chief motor nerve of the face. It exits the brainstem between the pons and the medulla. The primary motor function is the control of the muscles of facial expressions and conveys impulses of taste sensations from the anterior two-thirds of the tongue and…

Mathematically Modelling Clinical Resolutions of CSF pressure in Type-I Chiari Malformation and Syringomyelia Patients. Alexander S. Iacobucci, Andrew A. Hassall, Meagan E. Harrington, Korey V. Scanlin Introduction: Type-I Chiari Malformation is a neurological disorder describing the herniation of the cerebellum past the foramen magnum, occasionally resulting in a condition known as Syringomyelia. This disorder causes cysts, known as syrinxes, to form in the spinal cord and result in severe…

Introduction Trigeminal neuralgia (TN) is a debilitating condition characterized by unilateral stabbing facial pain along the divisions of cranial nerve V. The lifetime prevalence of TN is estimated to be 0.7 per 1,000 people and usually presents between the fourth and seventh decades(1, 2). First line management involves medical therapy, although 10-25% of patients fail to respond to standard medication regimens and some patients may become resistant to medical treatment over time(3, 4). For…

The immunological hypothesis was introduced by McGovern and coworkers.35-36 Friedreich hypothesized that the cause of facial paralysis was ~rheumatic" because of exposure to cold often followed by fever, chills and local pain and swelling in and around the neck.37 Brunninghausen speculated that the paralysis arose from the nerve sheath becoming thickened and compressed in stylomastoid foramen. The cold hypothesis, or paralysis e frigore, maintained that exposure to draughts produced the palsy.…

it would include the special images of the optic nerve, leading to possible lesions in that area. Treatment for Optic Neuritis includes a course of IV methylprednisolone with tapering courses of oral steroids afterwards. Visual deficits caused by optic neuritis may possibly worsen over time, so it's important to monitor the disease and see what the best course of treatment is. The optic nerve is located towards the back of the human eye, and it passes visual information from the retina to the…

Cranial Nerves [Your Name] [Mentor’s Name] [Course Code and Course Name] [The date] Cranial Nerves Introduction The cranial nerves are important nerves in our brain and they are located on the bottom surface of human brain. They are twelve pairs of nerves. Some of the cranial nerves are responsible to control body muscles, some of the cranial nerves are associated with the internal organs or glands such as human heart of lungs and some of the cranial nerves are responsible to take…

and environmental wisdom worldviews. Each one of these views addresses how we interact with nature and the effects our actions have on the resources it supply’s us. Sustainability is important in making sure we as a species do not go extinct as well as maintain the other species that inhabit the earth with us. Earth is the holds the only sustainable environment that we can live on as far as we know. Ove the years our population as a species has grown rapidly and faster than it ever has. One of…

Harvard professor Edward O. Wilson, in his nonfiction book, The Diversity Of Life, narrates Wilson’s life while elaborating on the topic of biodiversity. Scientists, Flockhart et al., in their scientific journal article, “Unravelling the annual cycle in a migratory animal: breeding-season habitat loss drives population declines of monarch butterflies,” hypothesize the causes of butterfly population loss. While Wilson’s purpose is to discuss science in a narrative manner to provide reading for…

Entire ecosystems have been deteriorating as a result of land disturbance, pollution, landfills deforestation, and overpopulation. As a result the ozone layer has suffered a major destitution of its entirety, there has been loss of biodiversity, impacts on human health, economic impacts, and the forced relocation and loss of species. Species need a habitat to live as does anything, but today most habitats have reached their ecological carrying capacity. Although efforts have been made in animal…
