Spinal 1 Flashcards
Embryologic development of vertebral column
sclerotome
forms neural plate
ectoderm
forms neural groove which houses the spinal cord and brain vesicles
neural plate
induces ectoderm to form neuroectoderm
notochord (remnant IVD as nucleus pulposus)
neural plate develop into?
"DON'T BE A MOANER, KNOW YOUR NEURAL PLATE" Macroglia cells (oligodendrocytes and astrocytes), Neurons in CNS, Ependymal cells, Retinal cells
forms the lining of the digestive tube and its associated structures, division foregut/midgut: liver and pancreatic buds
endoderm epithelium
primitive foregut includes?
mouth to stomach (glands of buccal cavity, esophagus, stomach, pharyngeal pouches and pharynx)
primitive midgut includes?
duodenum, jejunum, appendix and first part of transverse colon (duodenum to first part of transverse colon)
primitive hindgut includes?
second part of transverse colon, sigmoid and descending colon, rectum and upper anal canal (second part of transverse colon to the ass)
what does the allantois include?
PEE PEE-urinary bladder, vagina, urethra, prostate, and urethral glands
Somite cells form?
sclerotome (vertebral column, myotome, and dermatome)
simple squamous (filtration and diffusion)
capillaries, alveoli, and glomeruli
ciliated epithelium (circulate, move, sweep/clean)
brain vesicles, oviduct, lungs
ciliated pseudo stratified columnar (lining)
trachea, upper respiratory tract
non-ciliated pseudo stratified columnar (membrane)
vas deferens
foramen ovale becomes?
fossa ovalis (“thumb print” in the right atrium)
ductus arteriosus becomes?
ligamentum arteriosum (bypasses lung pulmonary trunk to arch of aorta)
umbilical vein becomes?
ligamentum teres (round ligament)
umbilical arteries become? **
MEDIAL umbilical ligaments
urachus becomes?
allantois
mandibular branch of trigeminal (V3) is what branchial arch?
1
facial nerve (VII) is what branchial arch?
2
glossopharyngeal nerve (IX) is what brachial arch?
3
superior laryngeal of vagus (X) is what pharyngeal arch?
4
INFERIOR laryngeal of Vagus (X) (recurrent branch) is what pharyngeal (branchial) arch?
6
Crude sensation and integrations “relay center”
thalamus
conscious interpretation of movement
cortex
main pathway between thalamus and cortex
through internal capsule and corona radiata
primary sensory gyrus
postecenteral gyrus
primary motor gyrus
precentral gyrus (motor in the front)
Where do sympathetics originate?
lateral horn, only in THORACICS
