She tells the nurse that she thinks her membranes have ruptured . Nurse Marina performs a the membranes have ruptured with the color blue . The physician orders Internal electronic fetal monitoring Vanessa asks Nurse Marina about any dangers the procedure causing harm to her babyNurse Marina's best response would be The procedure requires a application of a suction cup to the fetal scalp and poses a slight risk for the development of hematoma The procedure requires placement of an ultrasound transducer over your abdomen and poses no risk to you or your baby The procedure requires attachment of a small spiral electrode to the fetal scalp and poses a slight risk of soft tissue injury and infection The procedure requires insertion of soft, water-filled catheter into the uterus and poses no risk to you or your baby+Describe the process of implantation of the embryo, what cells are involved and their roles. +Describe placentation
- What are the significance of ORGATOGENESIS. State whether it is a normal developmental phenomena or not, support your answer.Q.No.2. Write 5 important points of development & axis formation in chick embryo in your own words.The 48-hr Chick Embryo Whole Mount (SEE IMAGE) Before you mount your slide on your microscope stage, take a good look at the morphology of the 48-hour embryo. Note the striking changes in morphology as compare, to the 33-hour embryo. There is a cephalic flexure or bending at the level of the midbrain. The head now lies on its left side. On the other hand dorsal side of the trunk is still turned up so the twisting of the embryo is noticeable. Verify these changes under the low power objective. Note the flexion and the torsion. In addition to the cranial/cephalic flexure there is also a cervical flexure at the level of the neck region. Very briefly go through the structures previously seen in the 33-hour chick. Observe the new structures appearing for the first time (Please visit the main website for viewing the whole mount of 33-hour and 48-hour chick embryo). Ectodermal Derivatives The prosencephalon is now divided into two regions: Telencephalon: This brain region is the anterior…
