Observation on nerve endings in human intrinsic laryngeal muscles by using silver impregnation method.

A silver impregnation method for motor and sensory nerves and their endings in formalin-fixed mammalian muscles.

A silver impregnation method is described which shows motor and sensory nerves and their endings in formalin-fixed mammalian muscles. The method works with the same reliability on flattened muscle pieces as well as on frozen sections. Large nerve bundles, myelinated and non-myelinated single axons, and terminals impregnated by this method stand out black against a light brown background.

Myotendinous nerve endings in human infant and adult extraocular muscles.

Myotendinous nerve endings in extraocular muscles of some mammals consist exclusively of palisade nerve endings incorporated in myotendinous cylinders. There is evidence for a similar form in man, some doubt remains. The objectives of the present study were to examine the structure and distribution of nerve endings in extraocular muscles of infant and adult human material. Muscles from five inf...

Palisade endings in human extraocular muscles.

The presence of nerve terminals in the tendinous insertions of human eye muscles was investigated histologically in adult human eye muscles obtained from donor eyes and in muscle pieces resected from juvenile patients undergoing surgical correction for strabismus. Lateral and medial recti, superior and inferior oblique muscles from adults, were stained "en bloc" using a silver impregnation meth...

Localization of Nerve Endings in Relation to Cholinesterase Deposits in Normal Human Eye Muscles.

Neroe endings and deposits of cholinesterase were stained in frozen sections of five normal striated human eye muscles with a stain that combines the neroe fiber techniijue of Hortega 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 he found around thin ...
