Release date- 16082019 - Researchers at Karolinska Institutet have discovered a new sensory receptor organ that is able to detect painful mechanical damage, such as pricks and impacts.
It also describes the general organization of the brain; how brain cells receive, process, and transmit information; how brain cells communicate with each other and the changes that occur; the various sensory receptor systems that enable humans to experience the world; how invertebrates illustrate neural and behavioral mechanisms; the architecture of the human brain; and development and brain plasticity.
The use of the sensory receptor system is also important in taking advantage of reflexes resulting from prolongation, and the occurrence of reflex actions performed by both muscle spindles that respond to the change in muscle length and rate of change.
But what if we can add another sensory receptor to our body?
Whole body vibration (WBV) is a current neuromuscular training method, which even at a low intensity provokes muscle length changes that stimulate the sensory receptor of the muscle spindle.
(11-13) The H-reflex is considered the electrical analog to the spinal stretch reflex, but has an important difference in that it bypasses the muscle spindle and thus facilitates study of the central mechanisms involved in motoneuron excitability, without the influence of the muscle spindle sensory receptor. The muscle spindle is bypassed because artificial electrical stimulation is applied at the sensory Ia afferent axons, rather than stretching the muscle to activate the muscle spindle.
The patterns of positive selection across mammalian, avian and aquatic vertebrate genomes show that sensory receptor genes are highly conserved.
This volume contains 12 chapters and a short communication on developmental gene expression regulation, with specific topics encompassing early developmental gene expression in vertebrates, regulating genes to modulate aging, sensory receptor gene regulation, inner ear cells, growth factors, estrogen function, neurosecretory cells, temporal patterns of gene expression in embryos, and brain-sex differentiation.
However, in the presence of pro-oxidant chemical agents, we demonstrated that even mild noise can yield oxidative stress leading to the death of sensory receptor cells for sound, the outer hair cells, and subsequent permanent impairment of auditory function (Fechter et al.
The problem lies in the sensory receptor mechanism in the muscles of the ankle, which adjusts the position of the foot on the ground to maintain balance.
The sensory receptor cells in the inner ear are nourished by the mineral zinc, beta-carotene, and vitamin A.
