1. Histology of juvenile skin of Lepidosiren paradoxa Fitzinger, 1837 (Sarcopterygii, Dipnoi)
Abstract: The skin of three juvenile Lepidosiren paradoxa specimens was examined. The epidermis was composed of a polystratified epithelium resting on a basement membrane, including mucus-secreting cells, and a cuticle of mucopolysaccharides on the surface. Two types of skin receptors, electroreceptors and mechanoreceptors, were found; the first type was loc

2. Histomorfometria dos mecanorreceptores e terminaÃÃes nervosas livres no quadril artrÃsico: estudo comparativo com quadril normal de cadÃver / Histomorphometry of mechanoreceptors and free nerve endings in hip joint: a comparative study in patients with secondary hip arthrosis and normal.
O interesse de pesquisadores pelo estudo do sistema proprioceptivo vem crescendo nas Ãltimas dÃcadas. Isto à decorrente da importÃncia da integridade deste sistema no tratamento das enfermidades ortopÃdicas. Os mecanorreceptores e as terminaÃÃes nervosas livres sÃo as unidades microscÃpicas fundamentais da propriocepÃÃo e do sistema nervoso aferen

3. FUNCTIONAL ANKLE INSTABILITY AND A REACTIVE STRATEGY TO AVOID AN ANKLE SPRAIN
(...)Functional ankle instability (FAI) is commonly defined as a condition in which individuals have recurrent sprain and/or a feeling of their ankle \"giving way (Freeman, 1965).\" The causes of this pathology are generally attributed to ankle muscular weakness, impaired proprioception, balance control, and neuromuscular reaction time or joint laxity, or a

4. Histomorfometric evaluation of mechanoreceptors and free nerves ending in the ankle lateral ligaments submitted physiologic stress / Avaliação histomorfométrica dos mecanorreceptores e terminações nervosas livres nos ligamentos laterais do tornozelo aplicada no estresse fisiológico
Microscopic examination of different tissues is widely used to evaluate the morphology of biological structures. When joint components such as capsules, ligaments and muscles are submitted to mechanic stress and pain, free nerves endings and mechanoreceptors located within these anatomical structures detect and relay this physiological information to the cen

5. Analysis of antenal sensilla patterns of Rhodnius prolixus from Colombia and Venezuela
Antennal sensilla patterns were used to analyze population variation of domestic Rhodnius prolixus from six departments and states representing three biogeographical regions of Colombia and Venezuela. Discriminant analysis of the patterns of mechanoreceptors and of three types of chemoreceptors on the pedicel and flagellar segments showed clear differentiati

6. Changes associated with laboratory rearing in antennal sensilla patterns of Triatoma infestans, Rhodnius prolixus, and Rhodnius pallescens (Hemiptera, Reduviidae, Triatominae)
We examined changes in the array of antennal sensilla of three species of Triatominae (Triatoma infestans, Rhodnius prolixus, and R. pallescens) following their establishment for different periods in laboratory culture. In each case, the laboratory colonies were compared with conspecific samples taken directly from the field, by quantitative analysis of the

7. Ultrastructure and chaetotaxy of sensory eeceptors in the cercaria of a species of Allopodocotyle Pritchard, 1966 (Digenea: Opecoelidae)
Previous investigations of sensory systems in opecoelid cercariae have focused on chaetotaxy and ultrastructure of sensory receptors. They revealed chaetotaxic patterns within family, genus, and species as well as different receptors. Chaetotaxic and ultrastructural observations have rarely been combined. We investigated the ultrastructure of cercarial senso

9. Distribution of mesencephalic nucleus and trigeminal ganglion mechanoreceptors in the periodontal ligament of the cat.
1. In anaesthetized cats recordings have been made in the mesencephalic nucleus of the fifth cranial nerve and the trigeminal ganglion from neurones that respond when forces are applied to the mandibular canine tooth. The site of the mechanoreceptors in the periodontal ligament and their distribution around the tooth root have been determined. 2. Receptors w

10. Abnormalities of oesophageal mechanoreceptors in canine acrylamide neuropathy.
Dogs exposed to acrylamide develop peripheral neuropathy and megaoesophagus. The properties of slowly adapting oesophageal mechanoreceptors were studied in six control and five acrylamide affected greyhounds in which the oesophagus had been surgically isolated under anaesthesia and oesophageal pressure was controlled while monitoring impulses in oesophageal

11. The distribution of mechanoreceptors in the periodontal ligament of the mandibular canine tooth of the cat.
1. Periodontal mechanoreceptor activity has been recorded from fibres in the inferior alveolar nerve. 2. A method has been developed for punctate and electrical stimulation of the periodontal ligament mechanoreceptors through a thin layer of bone overlying the labial aspect of the left mandibular canine tooth root. 3. The distribution of periodontal mechanor

12. Velocity sensitivity of human muscle spindle afferents and slowly adapting type II cutaneous mechanoreceptors.
1. Velocity information is used in the performance of movement. This study evaluated the ability of peripheral receptors to signal velocity in human subjects. 2. The velocity sensitivity of human muscle spindle afferents from the extensor digitorum muscles and slowly adapting type II cutaneous mechanoreceptors on the dorsum of the hand was evaluated with rec
