mechanoreceptors

specialized sensory nerve endings at termini of A-beta nerve fibres; preferentially subserve mechanosensation, e.g. touch, vibration (see Table 1)

The morphometric changes in the ZP could be explained by the activation of the mechanoreceptor Integrina / Pax-Fax, located in the chondrocytes, which through mechanical stimulation generates activation of the pathway PI3k / Akt, inhibiting the phosphorylation of B-Catenin, which on accumulation migrate to the nucleus promoting cell proliferation and MEC secretion genes (Takeuchi et al.
Recently, however, it has been reported that the number of mechanoreceptors of ACL recovers 12 months after the rupture (Relph and Herrington, 2016).
Accuracy of JPS was selected as a fatigue indicator since fatigue results in decreased proprioceptive feedback regarding joint movement and position due to decreased sensitization of the mechanoreceptors within the muscles and connective tissues surrounding the joint (Tripp et al.
LTR causes alterations in the length and tension of the muscle fibres and stimulates mechanoreceptors like the A[beta]-fibres.
14) In addition to the nociceptors, cervical spine facet joints contain type I, type II and type III mechanoreceptors.
Meniscus includes mechanoreceptors and nociceptors, which are located in the outer zone, and thus perform an important function in the proprioception [17].
1997, 1998, 1999), it means possible that Sg are candidate mechanoreceptors.
I am interested in exploring more fully embodied approaches to reading and intuiting data, making use of mechanoreceptors, thermoreceptors and chemoreceptors.
may be mechanoreceptors involved in the orientation of the parasite in relation to the flow of the ventilation water currents for feeding [39-42].
2) Vibrissal mechanoreceptors in the rat have been classified by their morphological features into: Merkel, lanceolate, club-like and Ruffini-like endings.
Human skin contains thousands of tactile sensory units only in the fingertip and a spider has hundreds of mechanoreceptors on each leg, but even a state-of-the-art humanoid such as NASA's Robonaut has only 42 sensors in its hand and wrist.
1993; Gronenberg 1996) work, in particular, makes a strong case based on histology and morphology of the hairs that they are mechanoreceptors attached to large neurons capable of rapid transmission of signals to the muscles controlling jaw-closure.
