Key concepts: Mesoderm Flashcards
when is the mesoderm made
in gastrulation
where the bilaminar disc turns into the trilaminar disc
function of the notochord
stimulates neuralation pathway in the ectoderm
specialisation of the mesoderm
differentiation of the mesoderm from medial to lateral l
paraxial
intermediate
lateral plate
subdivisions of the lateral plate mesoderm m
somatic
splanchnic
paraxial mesoderm
develops somites with cavities in the centre which are somatocoeles
these extend
and separate into 2 chunks
separations of the somatocoeles
dermatomyotome
sclerotome
subdivisions of the dermatomyotome
dermatome
myotome
sclerotome
dorsal to ventral
dermatome
spinal meninges
dermis
subcutaneous tissue
myotome
skeletal muscles:
epitaxial and hypoxia
sclerotome
vertebrae
intervertebral discs
ribs
intermediate mesoderm
renal system- kidneys and ureters
gonads- testes, ovaries (includes the epididymis, vas deferent, fallopian tubes and uterus)
lateral plate mesoderm
lateral folding in the longitudinal axis
1 layer moves with the ectoderm and one with the endoderm
somatic with ecto
splanchnic with endo
somatic basic
parietal layer of cavities
splanchnic basic
visceral layer of cavities
splanchnic layer
adrenal cortex
lymph nodes
spleen
GIT smooth muscle
cardiovascular system
myeloid stem cells
lymphoid cells
erythroid cells
