Relationship between the intervertebral foramina and the spinal nerves at the level of C4-T2 of the human fetal vertebral column.
In 80 human fetuses of both sexes, aged 4 to 7 months the spatiality of the intervertebral foramina and the area of the cross-section of the spinal nerves at the level of C4-T2 of the vertebral column were investigated. It was found that the narrowness of the intervertebral foramen is not related to the sex of fetus. The most probable places for such narrowness are intervertebral foramina C4-C5 and T1-T2 on the right side and C7-T1 on the left side.
