These are derived from what: →muscles →tendons →ligaments - MESODERM Paraxial Somatic These are derived from what: splanchnic - smooth muscle of organs - MESODERM Paraxial Splanchnic These are derived from what: urogenital system and kidneys - MESODERM Intermediate These are derived from what: →skull muscles, →dentine of teeth - MESODERM Head

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...

When does it emerge during embryo development?Centre that induces the formation of the organizer and later the dorsal mesoderm; emerges during the late blastula stage How does the fish organizer and Niewukoop Centre (NC) compare to their amphibian counterparts?They have si...

Hoorcollege 1 tot en met 10 van het vak Humane ontwikkeling. Bevat ook bespreking en toelichting van de relevante wetenschapsartikelen en casussen.

Dit document bevat alle tekeningen van het vak Diversiteit van de gewervelde dieren. Dit vak bestaat uit de tekeningen van de eerste 4 lessen, en dus niet de zelfstudie opdrachten van de rest van de lessen. In de les wordt er een kleurcode aangehouden van rood, groen en blauw. De rode kleur geeft het mesoderm weer, de groene kleur het endodermis en de blauwe kleur is het ectodermis. De zwarte kleur dit later wordt gebruikt is een algemene structuur waar niet direct een kleur aan gebonden is. ...
