CBNS 121 Exam Questions AND Correct Answers
"Cells that fire together, wire together" - ✔✔For a given
postsynaptic cell, inputs that are coactive tend to be
strengthened
"Out of sync, lose your link" - ✔✔Non co-active inputs are
weakened or eliminated
Achaetescute (Asc) homologs - ✔✔- Mash1
- Cash1
- Xash1
Activators - ✔✔- BMP inhibitors
- FGF signaling
induce neural tissue with anterior characteristics
Agrin - ✔✔- growth factor that promotes the development of
a motor end plate in skeletal muscle
- made by motoneurons and by muscle
,- clusters together & maintains ACh receptors in muscle
development
- creates an elaborate neuromuscular junction
Apoptosis - ✔✔programmed cell death (PCD)
Attractive cue molecules - ✔✔Sdf-1
Attractive cues - ✔✔guide a cell by "luring" it towards a
particular region
Axo-axonic Synapse - ✔✔presynaptic synapse where an axon
stimulates the presynaptic terminal of another axon;
Inhibitory - other neurons can dampen the effect of an action
potential
Axondendritic synapse - ✔✔An inhibitory synapse between
axon of one neuron and dendrite of another neuron
Axosomatic synapse - ✔✔An inhibitory synapse; axon to
soma; GABA is a common NTs
, BMP - ✔✔Bone Morphogenetic Protein
Chemoaffinity hypothesis - ✔✔The hypothesis that growing
axons are attracted to the correct targets by different
chemicals released by the target sites
Chemoattraction ligands - ✔✔Netrins
Chemorepulsion ligands - ✔✔Semaphorins
Chordin - ✔✔- expressed in the organizer
- has neural inducing activity
Coincidence Detection - ✔✔A process by which a neuron or a
neural circuit can encode information by detecting the
occurrence of temporally close but spatially distributed input
signals
Combinatorial coding - ✔✔Patterns of activity can modulate
responses to these molecules
