1. 1. Human extraocular muscles : molecular diversity of a unique muscle allotype

   Författare :Daniel Kjellgren; Fatima Pedrosa-Domellöf; Lars-Erik Thornell; Lillemor Wachtmeister; John Porter; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Ophtalmology; extraocular; muscle; myosin; protein c; laminin; serca; immunocytochemistry; human; Oftalmiatrik; Ophtalmology; Oftalmologi; oftalmiatrik; Ophtalmology;

   Sammanfattning : Introduction: The extraocular muscles (EOMs) are considered a separate class of skeletal muscle, allotype. Myosin is the major contractile protein in muscle. The myosin heavy chain (MyHC) isoforms are the best molecular markers of functional heterogeneity of muscle fibers. LÄS MER

3. 2. Human muscle spindles : complex morphology and structural organisation

   Författare :Jing-Xia Liu; William K. Ovalle; Umeå universitet; []
   Nyckelord :human; muscle spindle; intrafusal fiber; aging; biceps brachii; deep muscles of the neck; MyHC; mATPase; SERCA; anatomi; Human Anatomy;

   Sammanfattning : Muscle spindles are skeletal muscle mechanoreceptors that mediate the stretch reflex and provide axial and limb position information to the central nervous system. They have been proposed to play a major role in the pathophysiology of muscle pain. LÄS MER

4. 3. Context dependent adaptation of biting behavior in human

   Författare :Anders Johansson; Benoni Edin; Karl-Gunnar Westberg; Peter Svensson; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; EMG; bite force; human; mastication; muscles; jaw opening reflex; motor control; reflex modulation; periodontal attachment loss; periodontitis; fysiologi; Physiology;

   Sammanfattning : The focus of this thesis was to study an action that humans perform regularly, namely, to hold a morsel between the teeth and split it into smaller pieces. Three different issues related to this biting behavior were addressed:  (1) the effect of redu­c­ed perio­dontal tissues on food holding and splitting behavior; (2) the behavioral conse­quences of performing different bite tasks with different functional requirements, i.

5. 4. Exercise-induced muscle soreness : a qualitative and quantitative study of human muscle morphology and function

   Författare :Jan Fridén; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human; exercise; exertion; eccentric contractions; muscles; muscle strength; muscle soreness; fibre types; myofibrils; muscle proteins; histocy to chemistry; ultrastructure; stereology;

   Sammanfattning : Exercise-induced muscle soreness is characterized by stiffness, tenderness and pain during active movements and weakness of the affected musculature the days after unusually or particularly heavy work. The most pronounced subjective symptoms do not arise immediately but rather between a couple of hours to some days after the exercise (a delayed-onset of muscle soreness), the intensity of pain is greatest about 48 hours after the work.

7. 5. Extra- and intrafusal muscle fibre type compositions of the human masseter at young age. : In perspective of growth and functional maturation of the jaw-face motor system

   Författare :Catharina Österlund; Per-Olof Eriksson; Lars-Eric Thornell; Per Stål; Malin Ernberg; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; jaw; limb; human; muscle; morphology; fibre type; myosin heavy chain; muscle spindle; Morphology; Morfologi; anatomi; Human Anatomy;

   Sammanfattning : Muscles control body posture and movement by extrafusal and intrafusal (muscle spindle) fibres. The purpose of this thesis was to provide insight into the muscular basis for human jaw function at young age. LÄS MER
