Embryology 2023 Exam 2 Objectives: Lectures 9 (part)-16 | with complete solution Nodal is a signaling molecule produced by the primitive node. What is its role in the induction of the primitive streak and the establishment of left-right symmetry? It induces primitive streak and helps to establish left-right symmetry. It is a symmetry breaking molecule in the left side of the embryo. What is the first sign of asymmetry in early development? What roles are played by Nodal and Left-1? Involve...

Embryonic folding By the end of the fourth week of development, the embryo has already begun to take human form. It is nearly completely lined on the outside with ectoderm. Inside, the neural tube is continuing to develop within the dorsal mesenchyme. Adjacent to the neural tube, somites are forming in a segmental fashion. Lateral to this, intermediate mesoderm is beginning to form structures of the urogenital system and gonads. The lateral plate mesoderm had split into splanchnopleuric and s...

1. The part of the sperm containing proteolytic enzymes to digest the zona pellucida is the: A. capacitor B. head C. corona D. acrosome E. cumulus D. is correct. The acrosome is the part of the sperm containing proteolytic enzymes to digest the zona pellucida. It is exposed by the process of capacitation. Then, under the influence of substances released by corona radiata cells, it releases its proteolytic enzymes and penetrates the oocyte. 2. The ovulated mammalian oocyte is arre...
