2. 1. A sensory role for the cruciate ligaments : regulation of joint stability via reflexes onto the γ-muscle-spindle system

   Author : Per Sjölander; Håkan Johansson; Uwe Windhorst; Umeå universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Joint afferent; Mechanoreceptor; Cruciate ligament; Fusimotor neuron; reflex; muscle spindle afferent; motor control; cat;

   Abstract : Reflex effects evoked by graded electrical stimulation of the posterior articular nerves (PAN) of the ipsi- and contralateral knee joints were investigated using both micro-electrode recordings from 7 - motoneurones and recordings from single muscle muscle spindle afferents. Spindle afferent responses were also recorded using natural stimulation of different types of receptors, to elucidate if the articular reflexes onto the y -motoneurones were potent enough to significantly alter the muscle spindle afferent activity.

4. 2. Observations on morphology and function of cutaneous and subcutaneous sensory mechanoreceptors : an experimental study in mammals

   Author : Birgit Stark; Karolinska Institutet; Karolinska Institutet; []
   Keywords : mechanoreceptors; somatosensory organisation; blood-nerve barrier; Glucose transporter-1; nerve regeneration; TGF-ß family; neurotrophin receptors;

   Abstract : Tactile sensory discrimination is dependent upon an intact system of peripheral mechanoreceptors, their nerve fibre afferents with cell bodies in the dorsal root ganglion and the dorsal column-medial lemniscal system which relays tactile information from the skin to the cortex. Injury to any part of the afferent pathways leads to compromised mechanoreceptive perception. READ MORE

5. 3. Changes in human uterine innervation in term pregnancy and labor occurence and roles of neurotrophins and TRPV1

   Author : Berith Karlsson Tingåker; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Uterus; corpus uteri; cervix uteri; pregnancy; labor pain; neurotrophins; NGF; TRPV1; sensory corpuscles; human.;

   Abstract : Objective: Cervical ripening, is a prerequisite for successful labor, which is often very painful and involves an inflammatory reaction. However, little is presently known con-cerning nerve-related changes in the human uterus during labor and the fundamental hy-pothesis tested here was that labor pain emanates primarily from the cervix uteri.

6. 4. Studies on nerve terminations in human mucosa and skin

   Author : Marita Hilliges; Karolinska Institutet; Karolinska Institutet; []
   Keywords : Epithelium; herpes simplex; immunohistochemisry; Merkel cell; mucosa; nerves; oral; PGP 9.5; skin; stereology; urinary incontinence; vagina.;

   Abstract : In spite of their accessibility and important sensory function, the nervous tissue components of human oral and vaginal mucosa and skin have been subject to very few, if any, systematic investigations. Studies on the innervation of oral tissues have mainly focused on the dental pulp, the periodontium and the gingiva, probably because of specific clinical interest, thus largely neglecting the mucosa.
