Block 1 Lectures Flashcards
hollow ball of cells with fluid in the middle
blastocyst
important part of development where it organizes into ectoderm, mesoderm, endoderm
gastrulation
things formed by mesoderm
muscle, heart, bv, bones, cartilage, ct, kidneys, spleen, gonads
mesoderm stays quite blank during development
posterior
things formed by ectoderm
skin, hair, nails, sweat glands, mammary glands, enamel, CNS, PNS, sensory epithelium
normal number of vertebrae
33
there is blank between anterior and posterior parts of the ecto, meso, and endoderm
asymmetry
blank curve of the spine develops first
cervical lordotic
blank primary curves and blank secondary curves
1, 2
most mobile part of spine
cervical
unique part of cervical vertebra
transverse foramen
artery going through transverse foramen
vertebral artery
unique part of the thoracic vertebrae
rib articulations
most rigid part of vertebral column
rigid because of ribcage
largest and mobile part of vertebral column
lumbar
numbers of vertebral column
7, 12, 5, 5, 4
two ligaments of vertebral bodies
ALL, PLL
superficial to deep ligaments of vertebral arch
nuchal ligament, supraspinous ligament, interspinous ligament, ligamenta flava
ligaments between transverse processes
intertransverse ligament
articulating part of the occiput with the atlas
condyles
unique part of axis
dens
ligament holding the dens in place
transverse ligament
atlas allows these movements of head
flexion/extension
axis allows this movement of head and atlas
rotation
dens is aka
odontoid process
two ligaments that come off the tip of the dens to the occiput
alar ligaments
transverse ligament is on the blank
atlas
portion of ALL at the level of occiput/C1/C2
tectorial membrane
anterior atlantoocipital and atlantoaxial membranes are continuations of blank
ALL
posterior atlantoocipital and atlantoaxial membranes are continuations of blank
ligamentum flavum
