Human Female Fetus - Sacrum (10 week)
Large image version of plane D, close to midline (Stain - Haematoxylin Eosin). 0.3 mm scale bar
Sacral vertebra (S1–S5) and coccyx (last 3 vertebra) both shown unfused and as cartilage, formed from sclerotome of somites 31 to 44. The cartilage will later ossify in the fetal period. The vertebra will later fuse postnatally from adolescence to the adult (18 - 30 years).
Note the remnant of the notochord present in the vertebral body.
Spinal cord (medulla spinalis), conus medullaris, dura mater, film terminale. Spinal cord has developed from the neural tube.
- conus medullaris - (Latin, "medullary cone") is the tapered lower end of the spinal cord.
Rectum lies anterior to the vertebra and has developed from the hindgut. Note the differentiated epithelial wall of the rectum.
