Spatial orientation of horizontal cell axon terminals in the carp retina. 1985

K Negishi, and T Teranishi, and S Kato

In flatmounts of the carp (Cyprinus carpio) retina, 646 horizontal cells were singly marked by intracellular Lucifer yellow CH (LY) in the presence of dopamine or amphetamine, agents which were useful for restricting LY to single injected cells. Most axon terminals of cone-connected horizontal cells have a tendency to orient either radially or tangentially in the retinal field with respect to the optic disc as a center. Although the fluorescent cellular (dendritic field) area greatly varied depending upon the cell type (L-, RG- and YRB-type), the lengths of the axonal processes (axon plus terminal) were all comparable (400-600 microns). A few cells (4.1% of cells with visible axons) possessed a bifurcate axon with two axon terminals. Axons were not observed on rod-connected horizontal cells. The cellular area and the axonal length of L- and RG-type cells appeared to be smaller in the central than in the intermediate region of the retinal field.

UI	MeSH Term	Description	Entries
D009474	Neurons	The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM.	Nerve Cells,Cell, Nerve,Cells, Nerve,Nerve Cell,Neuron
D012160	Retina	The ten-layered nervous tissue membrane of the eye. It is continuous with the OPTIC NERVE and receives images of external objects and transmits visual impulses to the brain. Its outer surface is in contact with the CHOROID and the inner surface with the VITREOUS BODY. The outer-most layer is pigmented, whereas the inner nine layers are transparent.	Ora Serrata
D002347	Carps	Common name for a number of different species of fish in the family Cyprinidae. This includes, among others, the common carp, crucian carp, grass carp, and silver carp.

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.
