PLACENTA, FETAL MEMBRANES AND MULTIPLE GESTATION
DEVELOPMENT OF THE CHORIONIC SAC
• Trophoblast layer of the blastocyst
• Differentiation into: – Cytotrophoblast – inner layer – Syncytiotrophoblast – outer layer
• Development of extraembryonic mesoderm
• Formation of isolated lacunae spaces which later coalesce to form one big extraembryonic cavity – renamed chorionic sac
• Chorionic sac surrounds the amniotic cavity and primary umbilical vesicle
• Expansion of chorionic sac reduces the size of umbilical vesicle

Head and Neck development I: Pharyngeal apparatus and their derivatives
Pharyngeal Apparatus 1
•Pharyngeal arches are rod-like thickenings of
mesoderm present in the wall of the foregut.
•The ventral ends of the arches of the right and left sides meet in the middle line in the floor of the pharynx.
•In the interval between any two arches, the endoderm (lining the pharynx) is pushed outwards to form a series of pouches - endodermal, or pharyngeal, pouches.
•They are evident in the head and neck region by 4th week
•Resemble fish gills (branchia) thus their earlier name .Branchial apparatus - derived from the Greek word
branchia or gill
•They are derived from neural crest cells

DEVELOPMENT OF THE DIGESTIVE SYSTEM
The digestive system consists of the hollow GIT and the extrinsic glands
•Name the components of the hollow GIT in order
•Name the extrinsic glands of the digestive system
•The hollow GIT develops from the primordial gut, that forms during embryonic folding
•Extrinsic glands of the digestive system develop as diverticula from the developing
gut, hence retain their connections with the GIT via their ducts
