BCS 110 Exam 3 | UPDATED Questions with 100% Verified Answers
Question:
stem cells
Answer:
cells that can give rise to any type of cell in the body
Question:
germ layers
Answer:
Tissue layers in the embryos of all animals except sponges
Question:
endoderm
Answer:
the innermost germ layer. it eventually gives rise to the body's organs
Question:
mesoderm
Answer:
the middle germ layer that develops into muscle and bone and cartilage and blood and
connective tissue
Question:
ectoderm
Answer:
the outermost germ layer that gives rise to the central nervous system and the outer
covering of the body (skin, hair, nails)
Question:
neural plate
Answer:
,Thickened region of ectoderm formed by the third to fourth week of embryonic
development, which develops into the neural tube.
Question:
neural groove
Answer:
Groove resulting from further growth and thickening of the neural plate.
Question:
neural tube
Answer:
the precursor to the spinal cord and brain. the inside of this structure becomes the
ventricles.
Question:
precursors of the brain
Answer:
swellings at the end of the neural tube
Question:
glial cells
Answer:
assist in the migration of neural cells to their proper places in the body during neural
development. can use chemical signals to lure the neurons into their proper place.
Question:
synaptogenesis
Answer:
the formation of entirely new synapses or connections with other neurons
Question:
growth cones
Answer:
, precursor to axons
Question:
topographic mapping
Answer:
there is a similar arrangement of the CNS in the cortex and brainstem
Question:
apoptosis
Answer:
controlled cell suicide
Question:
neurotrophins
Answer:
chemicals that are responsible for the survival of neurons, axon guidance, and
synaptogenesis. they signal from the postsynaptic cell to signal the connection and
cancel apoptotic programs
Question:
pruning
Answer:
the process by which the brain destroys useless neural connections and strengthens
legitimate connections
Question:
neurodevelopmental disorder
Answer:
an impairment of growth and development of the CNS (generally the brain)
Question:
ancephaly
