Neural Development Quiz

Neural Tube Development

• The neural tube is a crucial structure in the developing embryo
• It forms the central nervous system (CNS)
• Neurulation is the process of forming the neural tube
• The ventricular zone contains neural progenitor cells, responsible for generating neurons and glial cells.

Neuronal Migration

• Neuronal migration is essential for the development of the nervous system
• Neurons move from their origin to their final positions in the brain and spinal cord
• This process occurs after the neural tube forms

Radial Glia

• Radial glia are glial cells that act as scaffolding during neuronal migration
• These cells provide a framework for migrating neurons to follow
• Radial glia also act as progenitor cells, producing various cell types in the brain

Growth Cones

• Growth cones are located at the tip of axons
• As the axon grows, the growth cone navigates through the extracellular environment
• Molecular cues guide the growth cone to its target

Apoptosis

• Apoptosis is a process of controlled cell death
• It plays a critical role in development, tissue homeostasis, and elimination of damaged cells

Neurotrophins

• Neurotrophins are proteins involved in the development, survival, and function of neurons
• They are essential for neuronal growth, differentiation, and maintenance
• Neurotrophins influence neural plasticity and repair

Nerve Growth Factor (NGF)

• NGF is a neurotrophic factor critical for the survival, development, and function of neurons
• It was the first neurotrophin discovered
• NGF research focuses on its role in neuronal health and diseases

Myelination

• Myelination is the process of forming a myelin sheath around axons
• This sheath is essential for efficient transmission of electrical impulses
