Human Embryo Carnegie stage 11
This scanning EM of the stage 11 human embryo is the same image as Stage11 sem5 with the addition of direction of view including (common) terms.
- ventral and anterior both mean toward the front of the body.
- dorsal and posterior mean the back of the body.
- rostral, cranial, and cephalic and superior all mean toward the head or the upper part of a structure
- proximal means closer to the body
- distal is away from the body
- medial describes a structure toward the midline of the body
- lateral describes a structure away from the midline of the body
- coronal or frontal plane - divides the body into ventral and dorsal
- sagittal - divides the body into left and right
- midsagittal or median sagittal - is the plane exactly in the midline
- transverse or horizontal plane - divides the body into rostral and caudal
