Railroad track configuration of the ear. With some researchers suggesting that attached would be better described as lobeless.

Normal Ear Shape

Innovative ears for years freight railroads have used ultrasound technology to look inside a track and determine its health the same way that a doctor determines the health of a human body.

Railroad track ears. Note that the prominent horizontal crus of the helix in combination with a prominent and parallel inferior crus of the antihelix. Railroad track ears represent a subjective and subtle anomaly of the ears that is associated with the phenotype of fas. Curved fifth finger clinodactyly and the upper palmar crease that widens and ends between the second and third fingers.

Ear parallel to the ear crease below railroad track appearance. In the normal population free earlobes have been described as dominant. Hockey stick crease hand appearance.

A prominent horizontal crus of the helix that reaches the edge of the antihelix in combination with a prominent and parallel inferior crus of the antihelix results in two parallel rails. Railroad track ear appearan. Characteristic features of a hand of a child with fetal alcohol spectrum disorders.

Railroad track associated with fatal alcohol syndrome the curve at top part of outer ear is underdeveloped and folded over parallel to curve beneath. Erdeveloped upper part of the ear parallel to the ear crease below. It was not necessary to put your ear actually on the track if you had a solid piece of wood or metal such as a pick axe handle you could place one end firmly onto the track and your ear to the other end.

These track check ups have helped railroads identify invisible imperfections before they pose a danger to trains.
