[Linear measurements of the rhomboid fossa (the fourth ventricle in man]

The linear sizes of the rhombiod fossa of the human brain were studied with the help of the M. M. Sauliak-Savitskaja's device. Under study were 72 objects of the brain of humans from 20 to 78 years of age. The obtained data were statistically treated. No relationship between the sizes of the rhombiod fossa, sex and age was revealed, no statistically significant distinctions between the sizes of the right and left parts of the rhombiod fossa were revealed either. Between the length and width of the rhomboid fossa there exits a direct correlative relationship, the width of the rhomboid fossa having more close correlative relationships with the length of the superior part of the fossa rombiodea that the length of its inferior part.
