Clustering of primary afferent fibers in peripheral nerve fascicles by sensory modality. 1986

W J Roberts, and S M Elardo

The spatial organization of cutaneous afferent fibers in the cat saphenous nerve was studied by recording from functionally identified units in split filaments. It was found that within each fascicle, fibers tend to be clustered together with others of like modality; they are not randomly distributed. These results suggest that the sensory modality of primary afferent neurons is determined prior to their innervation of the skin.

D008465 Mechanoreceptors Cells specialized to transduce mechanical stimuli and relay that information centrally in the nervous system. Mechanoreceptor cells include the INNER EAR hair cells, which mediate hearing and balance, and the various somatosensory receptors, often with non-neural accessory structures.

D009475 Neurons, Afferent Neurons which conduct NERVE IMPULSES to the CENTRAL NERVOUS SYSTEM. Afferent Neurons,Afferent Neuron,Neuron, Afferent
D010141 Pacinian Corpuscles Rapidly adapting mechanoreceptors found in subcutaneous tissue beneath both hairy and glabrous skin. Pacinian corpuscles contain an afferent nerve fiber surrounded by a capsule with multiple concentric layers. They have large receptive fields and are most sensitive to high-frequency stimuli, such as vibration. Pacinian Corpuscle,Corpuscle, Pacinian,Corpuscles, Pacinian
D010525 Peripheral Nerves The nerves outside of the brain and spinal cord, including the autonomic, cranial, and spinal nerves. Peripheral nerves contain non-neuronal cells and connective tissue as well as axons. The connective tissue layers include, from the outside to the inside, the epineurium, the perineurium, and the endoneurium.

D002415 Cats The domestic cat, Felis catus, of the carnivore family FELIDAE, comprising over 30 different breeds. The domestic cat is descended primarily from the wild cat of Africa and extreme southwestern Asia. Though probably present in towns in Palestine as long ago as 7000 years, actual domestication occurred in Egypt about 4000 years ago.

D005727 Ganglia, Spinal Sensory ganglia located on the dorsal spinal roots within the vertebral column. The spinal ganglion cells are pseudounipolar. The single primary branch bifurcates sending a peripheral process to carry sensory information from the periphery and a central branch which relays that information to the spinal cord or brain.

D006197 Hair A filament-like structure consisting of a shaft which projects to the surface of the SKIN from a root which is softer than the shaft and lodges in the cavity of a HAIR FOLLICLE. It is found on most surfaces of the body. Fetal Hair,Hair, Fetal,Lanugo,Fetal Hairs,Hairs,Hairs, Fetal
D000222 Adaptation, Physiological The non-genetic biological changes of an organism in response to challenges in its ENVIRONMENT.

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA. Animal,Metazoa,Animalia
D012867 Skin The outer covering of the body that protects it from the environment. It is composed of the DERMIS and the EPIDERMIS.
