Anatomy of the Forearm Musculoskeletal Block - Lecture 9
Anatomy of the forearm Musculoskeletal Block - Lecture 9 Objective: ✓ List the names of the Flexors and Extensor Group of Forearm (superficial & deep muscles). ✓ Identify the common flexor origin of flexor muscles and their innervation & movements. ✓ Identify supination & pronation and list the muscles produced these 2 movements. ✓ Describe the effect of injury of the muscle or its origin ✓ Identify the common extensor origin of extensor muscles and their innervation & movements. Color index: Important In male’s slides only In female’s slides only Extra information, explanation Editing file Contact us: [email protected] Forearm 1- The forearm extends from the elbow to wrist. 2- It posses two bones radius laterally and ulna medially. 3- The two bones are connected to each other by interosseous membrane. 4- This membrane allows movement of pronation and supination while the two bones are connected together. 5- also it gives origin to the deep muscles. Fascial compartment of the forearm 1- The forearm is enclosed in a sheath of deep fascia, which is attached to the posterior border of ulna (it encircle the forearm completely (Without touching the radius) and return again to the posterior border of the ulna) 2- This fascial sheath together with the interosseous membrane and fibrous intermuscular septa divides the forearm into (anterior and posterior) compartments each having its own muscles, nerves and blood supply. (The radius and ulna are connected by 3 structures: the interosseous membrane, superior radioulnar joint and inferior radioulnar joint). Anterior compartment - FLEXOR GROUP 1- 8 muscles.. 2- They act on the elbow and wrist joints and the fingers. -

As is commonly known, infection of the submas- seteric space originates from mandibular third molars; hence, maxillary molars seem to be an unlikely source of infection. -

SPLIT-ERGATIVITY in HITTITE Petra Goedegebuure (University of Chicago)
Published in: Zeitschrift für Assyriologie und vorderasiatische Archäologie. Volume 102, Issue 2, Pages 270–303, ISSN (Online) 1613-1150, ISSN (Print) 0084-5299, DOI: 10.1515/za- 2012-0015, January 2013 1 SPLIT-ERGATIVITY IN HITTITE Petra Goedegebuure (University of Chicago) “it is possible that all languages show ergativity on some level” (McGregor 2009, 482) 1. Introduction2 As a highly heterogeneous phenomenon ergativity remains a conundrum for linguistic theory. The ergative case has been treated as a structural case, an inherent/lexical case, or rather as a mix (Butt 2006). Split-ergativity is thought to arise as an epiphenomenon, as ‘collateral damage’ of diachronic change after reinterpretation of passive constructions with instrumentals (Dixon 1994) or through reanalysis of transitive null-subject clauses with inanimate instrumentals (Garrett 1990b). Alternatively, case assignment and therefore also split-ergativity ultimately depends on synchronic structural properties of the clause (Merchant 2006). It has been claimed that only 25% of the world’s languages shows ergativity (Van de Visser 2006), or that “all languages show ergativity on some level” (McGregor 2009, 482). Irrespective of the correct ratio, split-ergativity seems to be the norm among languages that show ergativity. When the ergative split is based on semantic features of noun phrases, it is generally assumed that animacy plays a major role. Silverstein (1976) has shown that pronouns and nouns can be hierarchically arranged based on semantic features such as person, number, or grammatical gender. The strength of this hierarchy is that if agent marking is attested for the first time at a certain point in the hierarchy, all nominals lower in the hierarchy will carry agent marking as well. -

Compartment Syndrome and Fasciotomy
Compartment syndrome and fasciotomy The aim of this information sheet is to help answer some of the questions you may have about having a fasciotomy for compartment syndrome. If you have any questions or concerns, please do not hesitate to speak to a doctor or nurse caring for you. What is compartment syndrome? Compartment syndrome occurs due to increased pressure within a confined space or compartment in the calf or thigh. This could be in just one leg or in both legs. If untreated, it can restrict the blood supply to muscles in the affected compartment and can result in necrosis (death) of the muscles. Nerves are also damaged from this pressure. This can result in loss of sensation in the skin and paralysis of the muscles they supply. Rapid diagnosis and treatment to relieve the pressure can lead to complete recovery of the affected muscle. What causes compartment syndrome? If the blood supply to your leg or legs has been interrupted, when blood flow is restored the muscles in the leg/legs swell causing compartment syndrome. If you have been admitted to hospital as an emergency with poor blood supply to the leg, this can happen when the blood flow is restored. The initial injury usually causes swelling of the muscle and tissues within the fascial compartment of the limb. This causes the pressure within the compartment to rise. As time progresses, and as the degree of pressure increases, blood flow to the muscles reduces. This lack of blood flow means that oxygen is not delivered effectively to the muscles and nerve damage begins to occur. -

2 Aetio-Pathogenesis and Clinical Pattern of Orofacial Infections Babatunde O. Akinbami Department of Oral and Maxillofacial Surgery, University of Port Harcourt Teaching Hospital, Rivers State, Nigeria 1. Introduction Microbial induced inflammatory disease in the orofacial/head and neck region which commonly arise from odontogenic tissues, should be handled with every sense of urgency, otherwise within a short period of time, they will result in acute emergency situations.1,2 The outcome of the management of the conditions are greatly affected by the duration of the disease and extent of spread before presentation in the hospital, severity(virulence of causative organisms) of these infections as well as the presence and control of local and systemic diseases. Odontogenic tissues include 1. Hard tooth tissue 2. Periodontium 2. Predisposing factors of orofacial infections Local factors and systemic conditions that are associated with orofacial infections are listed below. Local factors Systemic factors 1. Caries, impaction, pericoronitis Human immunodeficiency virus 2. Poor oral hygiene, periodontitis Alcoholism 3. Trauma Measles, chronic malaria, tuberculosis Diabetis mellitus, hypo- and 4.

Through this study, attempt to answer--or at least bring attention to--such questions as, Why do some nouns have consimi Jar adjec tives, others collateral adjectives, and still others both consimilar and collateral adjectives? What etymological, morphological, and phonologi cal similarities and differences do common nouns, consimilar adjectives, and collateral adjectives manifest? How knowledgeable are native speak ers of English about consimilar and collateral adjectives? And, given a choice, which types of adjectives would such speakers prefer to use? While my answers to these questions are not always complete or satis factory, by recording my methods, speculations, expectations, and mis takes, I hope that future researchers can succeed where I have failed. This project grows out of my lifelong interest in words and etymol
