test 2 LAB Flashcards
auditory ganglion (CN 8)
cerebral hemisphere
telencephalon becomes constricted into two “future cerebral hemisphere
cornea
cranial nerve 12
diencephalon
diencephalon→ telencephalon → cerebral hemisphere
blue: dorsal root
green: dorsal root ganglion
endolymphatic duct
attached to otic vesicles
geniculate ganglion
CN 7
(ventral to auditory ganglion (CN8)
infundibulum
evagination of the prosencephalon → pituitary gland (ventral to Rathke’s pouch which becomes the pars distalis, pars intermedia, pars tuberalis of the pituitary gland)
jugular ganglion (CN 10)
dorsal to CN9 and ventral and lateral to CN 12
Lens
Mesencephalon
(ventral to metencephalon)
Metencephalon
Myelencephalon
olfactory pits
otic vesicle
pigmented layer (retina)
rathke’s pouch
dorsal to infundibulum which is an evagination of the prosencephalon → pituitary gland (ventral to Rathke’s pouch which becomes the pars distalis, pars intermedia, pars tuberalis of the pituitary gland)
semilunar ganglion (CN5)
sensory layer (retina)
green is pigmented layer
spinal cord
superior ganglion (CN9)
Telencephalon
diencephalon → telencephalon → cerebral hemisphere
ascending aorta
left atrium
right atrium
bulbar ridges
bulbar cordis/ conus truncus
green: descending aorta
right dorsal aorta
superior mesenteric artery
left dorsal aorta
ductus arteriosus
left subclavian
right dorsal aorta
ductus arteriosus
left dorsal aorta
ductus venosus
(vitelline and left umbilical vein to sinus venosus)
endocardial cushion
hepatic portal vein
inferior vena cava
interatrial septum
intersegmental artery
branched of dorsal aortae, contribute to vertebral, subclavian, intercostal and lumbar arteries
inter-ventricular foramen
interventricular septum
pulmonary trunk
in fetal all blood leaves from the RV in the bulbus cordis which turns into pulmonary trunk and ascending aorta)
right sinus venosus
initially most caudal chamber of heart, delivers venous return to atrium, originates heart beat will turn into SA node in adult
spiral septum
bulbus cordis leaves the RV and then is divided by the spiral septum to create Ascending aorta and pulmonary trunk
green: left dorsal aortae
blue: subclavian
blue: superior mesenteric artery
green: descending aorta
umbilical arteries
descending aorta branches into umbilical arteries (connection seen at rump of baby)
left umbilical vein
right umbilical vein
left ventricle
right ventricle
allantoic stalk
within the umbilicus, canal in the umbilical cord connecting the cloaca, then later the urogenital sinus with the allantois carries urine
cloaca
caudal chamber of the digestive tract
turns into urogenital sinus and rectum
cloacal membrane
turns into/opens up into cloaca which turns into urogenital sinus and rectum
genital ridge
glomerulus
mesonephros
mesonephric duct
mesonephric tubules
metenephric duct
rectum
renal pelvis
metenephric duct → future renal pelvis
future secretory tubules (metanephrogenic mesenchyme)
urinary capsule
(capsule around Bowman’s capsule)
urogenital sinus
common bile duct
drains into the duodenum
orange: cystic duct
red: gallbladder
duodenum
esophagus
orange: cystic duct
red: gallbladder
intestines
limb buds
liver
lung bud
dorsal pancreas
green: dorsal pancreas
orange: ventral pancreas

stomach
stomodeum (future mouth)
Thyroid gland
Trachea
Tuberculum Impar (future tongue)
umbilicus
