PSYB64H3 Lecture Notes - Lecture 5: Sonic Hedgehog, X-Inactivation, Radial Glial Cell
Document Summary
Snp or single nucleotide polymorphism alleles whose genetic code differs in only one location. Bmps and allow for the growth of neural tissue. Filopodia and lemellipodia are both capable of movement and pull the growing branches behind them microtubules from the main body of the cone move forward as the cone extends, forming a new segment of axon or dendrite. Filopodia can signal the growth cone to move in any direction. respond to the attracting and inhibiting chemicals released by the guidepost cells along the way. Axons that are growing in the same direction stick together in a process of fasiculation. this sticking together is caused by cell adhesion molecules or cams. which are molecules on the surface of growing axon. Formation of new synapses cell. interaction with the target cell influences the type of nt released by the presynaptic. Steps in the formation of synapse at the neuromuscular junction: growth cone approaches muscle fiber.
