x exam 2 body cavity formation Flashcards
what starts process of body cavity formation after gastrulation
subdivision of mesoderm
paraxial mesoderm
adjacent to notochord
intemrediate mesoderm
lateral to paraxial mesoderm
lateral plate mesodemr
lateral to intermediate
paraxial mesoderm forms
axial parts of musculoskeletal sstem; muscles of appendicular musculoskeletal system (axial skeleton, voluntary trunk muscles and extermities and some dermis)
paraxial mesoderm subdivided into
somites
cranial most 7 pairs
incomplete division, head structures
remainder somites
divide completely, body structures
intermeidate mesoderm forms
urogenital systems (majority)
lateral plate mesoderm extends
extraembryonic as part of fetal membanes
lateral plate mesoderm subdivides into
somatic mesoderm and splanchnic mesoderm
somatic mesoderm associated with
ectoderm
somatic mesoderm gives rise to
dermis of integumentary system; connective tissus of limbs
splanchnic mesoderm associated with
endoderm
splanchnic mesoderm gives rise to
respiratory system
GI system
caudal most parts of urogenital system (exits)
