ooplasm

Changes in the nucleus, ooplasm, and the surrounding layers characterize the oocyte maturation process.

Where the spermatozoon is about to pierce, the yolk (ooplasm) is drawn out into a conical elevation, termed the cone of attraction or reception cone.

Through circulation it is transported to the follicle cells that surrounds the maturing ovum,and is deposited in the form of yolk platelets and granules in the ooplasm.

Looking more closely as he deftly handled a micro pipette Dr. Wingate experienced the thrill of creation as he observed two pro nuclei within the ooplasm of the egg.

The ooplasm consists of the cytoplasm of the ordinary animal cell with its spongioplasm and hyaloplasm, often called the formative yolk; and the nutritive yolk or deutoplasm, made of rounded granules of fatty and albuminoid substances imbedded in the cytoplasm.
