1. 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

2. Ultrastructure of free-ending nerve fibres in oesophageal epithelium.
For the first time, at the ultrastructural level, the existence of free-ending, intraepithelial nerve fibres has been demonstrated in the oesophagus wall of adult cats and monkeys. Their form, the way they penetrate the epithelium, their location within the epithelium and their relationships with neighbouring cells have been established. A sensory function i

3. Calcium currents at motor nerve endings: absence of effects of adenosine receptor agonists in the frog.
1. The effects of adenosine (50 microM) and 2-chloroadenosine (1-25 microM) were studied on Ca2+ currents in frog motor nerve endings. 2. Ca2+ currents associated with the synchronous, neurally evoked release of acetylcholine (ACh) were measured using either perineural or patch recording methods. Tetraethylammonium and/or 3,4-diaminopyridine were employed to

4. Observations on the structural and innervation of the rat snout.
Light and electron miscroscopy were employed to study the structure and innervation of the rat snout. The hairless skin at the tip of the snout was covered in epidermal ridges similar to the ridges seen on primate finger skin. Three types of nerve ending were observed in relation to the surface of snout: corpuscular, found in dermal papillae between epiderma

5. Specificities of afferents reinnervating cat muscle spindles after nerve section.
1. We have made quantitative assessments of the sensory reinnervation and recovery of peroneus brevis muscle spindles following section and epineurial repair of the common peroneal nerve. After 6-50 weeks recovery, single-unit, dorsal-root recordings were made of the responses to ramp-and-hold or sinusoidal stretch of the reinnervated spindles, which were su

6. The sensory innervation of the nasal glabrous skin in the short-nosed bandicoot (Isoodon macrourus) and the opossum (Didelphis virginiana).
The glabrous skin at the anterior end of the snout of the short-nosed bandicoot and the American opossum was investigated by electron microscopy. In both species of animals, this region was lined by skin with broad epidermal pegs, innervated by three types of intraepidermal nerves. These were intraepidermal nerves which penetrated the epidermis up to the lev
