The bulboid corpuscles (end-bulbs of Krause, Krause corpuscles) are cutaneous receptors in humans and other animals. The end-bulbs of Krause were named after the German anatomist Wilhelm Krause (1833–1910). [1] [2]
Krause discovered and described mechanoreceptors that were to become known as "Krause's corpuscles", sometimes referred to as "Krause's end-bulbs". [citation needed] His name is also associated with: "Krause's membranes": defined as isotropic bands in striated muscle fiber that consist of disks of sarcoplasm and connect the individual fibrils ...
Merkel nerve endings have a widely distributed in glabrous and hairy skin, in hair follicles, and in oral and anal mucosa. [citation needed]Meckel nerve endings are most numerous beneath the ridges of the fingertips which make up fingerprints, and less so in the palms and forearm.
The end-bulb of Krause or bulboid corpuscle detects temperatures above body temperature. Ruffini's end organ detects temperatures below body temperature. TRPV1 is a heat-activated channel that acts as a small heat detecting thermometer in the membrane which begins the polarization of the neural fiber when exposed to changes in temperature.
Axon terminals (also called terminal boutons, synaptic boutons, end-feet, or presynaptic terminals) are distal terminations of the branches of an axon. An axon, also called a nerve fiber, is a long, slender projection of a nerve cell that conducts electrical impulses called action potentials away from the neuron's cell body to transmit those ...
The middle fibers are supposed by Krause to assist in the erection of the corpus spongiosum, by compressing the erectile tissue of the bulb. The anterior fibers also contribute to the erection of the penis by compressing the deep dorsal vein of the penis as they are inserted into, and continuous with, the fascia of the penis.
Tactile corpuscles or Meissner's corpuscles are a type of mechanoreceptor discovered by anatomist Georg Meissner (1829–1905) and Rudolf Wagner. [1] [2] This corpuscle is a type of nerve ending in the skin that is responsible for sensitivity to pressure.
Artistic interpretation of the major elements in chemical synaptic transmission. An electrochemical wave called an action potential travels along the axon of a neuron.When the action potential reaches the presynaptic terminal, it provokes the release of a synaptic vesicle, secreting its quanta of neurotransmitter molecules.
