This above is my pencil drawing of a human spermatozoon and I was drawing this from a medical photo.. This is number 1 sketch in a series of how humans develop in the womb. This show the parts of the spermatozoon.The word spermatozoa is plural and there are millions of sperm that swim up the uterus to try to fertilize the human egg.

This is second sketch in a series of how humans develop in the womb. This is the zygote preparing to begin division into many cells and this occurs about 12 hours after the spermatozoon enters the human egg.

This is my third sketch in this series of how humans develop in the womb. This shows the cell dividing into two cells and of course that process repeats continuously.

This is pencil drawing number four of this effort to show how the human develops in the womb. I think you should be able to read my notes that are intended to provide more info about each stage of development.

This is pencil drawing number five of this series and shows the human embryo at 12 days after fertilization attaching the self to the wall of the uterus.
This drawing shows how the egg gets from the ovary to the uterus. The fallopian tubes are tiny but obviously i enlarged
all drawings so you could see them. The eggs and sperm are only visible by microscope until a few days.

This is a watercolor sketch of a human embryo, dorsal view, at the age of 21 days since fertilization It shows that the backbone is developing and the vertabra forming.

This watercolor drawing shows the human embryo in the yolk sac and the yolk that nurtures the new tiny human that would be about
3/16 of an inch at this stage of development. By 28 days, the new tiny human has a beating heart, a brain spinal cord, nervous system,eyes, the beginning of 40 pairs of muscles, and 33 vertabrae, and the kidney pronephros .
This sketch shows the human embryo at 7 weeks after fertilization. This is watercolor sketch.
These are my original sketches in pencils or watercolors, and uploaded to this site for the purpose of teaching the public on the topic of human life, and of course to discourage people from aborting tiny humans!
