  1. 1. Neck function in rhythmic jaw activities

    Författare :Birgitta Häggman-Henrikson; Antoon DeLaat; Umeå universitet; []
    Nyckelord :chewing; head; human; jaw; mandible; motor control; movement; neck; temporomandibular disorders; whiplash injury; odontologi; Odontology;

    Sammanfattning : Previous studies in animals and humans show anatomic and physiological connections between the trigeminal and cervical regions. This investigation tested the hypothesis of a functional integration between the human jaw and neck motor systems in rhythmic jaw activities. LÄS MER

  3. 2. 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

  4. 3. Hypothalamic and cortical control of jaw reflexes

    Författare :Kurt Å. Olsson; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cat; Oral projections; Cerebral cortex; Cytoarchitecture; Hypothalamus; Defence-Attack area; Jaw reflexes; Bruxism; Myofascial pain dysfunction;

    Sammanfattning : The subject of the thesis is a study of the projections from low threshold oral and face afferents to the cerebral cortex and of descending motor control mechanisms originating in the cerebral cortex or the hypothalamus and influencing the jaw reflexes.Cats anaesthetized with chi oral ose were used for the experiments.

  5. 4. Mastication in jaw muscle pain

    Författare :Samaa Al Sayegh; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Background: Integrated Pain Adaptation Models suggest a possible pain-motor interaction. Mechanisms affecting the jaw muscle spindles seem to affect the ability to bite and chew, suggesting that jaw muscle pain may be a potential modifier of mastication in humans. LÄS MER

  7. 5. Conventional spiral and low-dose computed mandibular tomography for dental implant planning

    Författare :Annika Ekestubbe; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Artifacts; Dental Implantation; Endosseous; methods; Dental Implants; Humans; Jaw; Edentulous; radiography; Mandible; radiography; Patient Care Planning; Phantoms; Imaging; Radiation Dosage; Radiography; Dental; methods; Reproducibility of Results; Tomography; X-Ray; instrumentation; methods; Tomography; X-Ray Computed; methods;

    Sammanfattning : Absorbed doses to radiosensitive organs in the head and neck from pre-implant conventional hypocycloidal, conventional spiral and computed tomography (CT) were measured with thermoluminescent dosimeters in an anthropomorphic phantom head. From conventional tomography organ doses, except to the major salivary glands, were below 0.2 mGy. LÄS MER
