Abstract
Nerve endings and deposits of cholinesterase were stained in frozen sections of five normal striated human eye muscles tvitli a stain that combines the nerve fiber technique of liortega and the method of Koelle and Friedenwald for the demonstration of cholinesterase. Cholinesterase deposits are found at the base of the motor end plates. Dense cholinesterase deposits can also be found around thin nerves which form simple ring- or buttonshaped endings on muscle fibers. No cholinesterase is seen at the endings of the other type of thin (sympathetic?) nerves which also supply the muscle fibers and have networklike end formations as well as at all types of sensory (afferent) nerve endings in human eye muscle.
