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

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

    Abstract : 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. READ MORE

  4. 2. Satellite cells in human skeletal muscle : molecular identification quantification and function

    Author : Mona Lindström; Lars-Eric Thornell; Hannu Kalimo; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; satellite cell markers; NCAM; Pax7; MyoD; myogenin; DLK1 FA1; c-Met; human skeletal muscle; immunohistochemistry; muscle growth; muscle hypertrophy; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi; anatomi; Human Anatomy;

    Abstract : Skeletal muscle satellite cells located between the plasma membrane and the basal lamina of muscle fibres, could for many years, only be studied in situ by electron microscopy. The introduction of immunohistochemistry and the discovery of molecular markers of satellite cells then made them accessible for light microscopic studies and a wealth of information is today available.

  5. 3. Influences of paratendinous innervation and non-neuronal substance P in tendinopathy : studies on human tendon tissue and an experimental model of Achilles tendinopathy

    Author : Gustav Andersson; Patrik Danielson; Sture Forsgren; Håkan Alfredson; David A. Hart; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Achilles tendon; tendinopathy; tendinosis; paratenon; innervation; substance P; neuropeptides; neurokinin-1 receptor; Anatomy; Anatomi; anatomi; Human Anatomy;

    Abstract : Pain of the musculoskeletal system is one of the most common reasons for people seeking medical attention, and is also one of the major factors that prevent patients from working. Chronic tendon pain, tendinopathy, affects millions of workers world-wide, and the Achilles tendon is an important structure often afflicted by this condition. READ MORE

  6. 4. 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

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

    Abstract : 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. READ MORE

  7. 5. The human Achilles tendon : innervation and intratendinous production of nerve signal substances - of importance in understanding the processes of Achilles tendinosis

    Author : Dennis Bjur; Sture Forsgren; Patrik Danielson; Håkan Alfredson; Tomas Movin; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Achilles tendon; tendinosis; tendinopathy; nerve signal substances; hälsena; Achillessena; tendinos; tendinopati; Orthopaedics; Ortopedi; anatomi; Human Anatomy;

    Abstract : Tendinopathies are painful tendon conditions of presumably multifactorial genesis. In tendinosis, as in Achilles tendinosis, there is apart from pain also morphological changes which are described as degenerative with no signs of inflammation. The exact mechanisms behind these conditions are still, to a large extent, unknown. READ MORE
