Study Notes
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
