myelin sheath Sentence Examples
- The myelin sheath, composed of specialized Schwann cells, insulates the axons of neurons, facilitating faster electrical impulses.
- Myelinated axons transmit signals far more rapidly than unmyelinated ones due to the insulating properties of the myelin sheath.
- Multiple sclerosis, an autoimmune disorder, targets the myelin sheath, disrupting nerve communication.
- Charcot-Marie-Tooth disease, a genetic disorder, affects the production of myelin sheath, leading to muscle weakness and sensory impairments.
- The myelin sheath is crucial for efficient neural transmission, enabling coordination and rapid responses to stimuli.
- Schwann cells in the peripheral nervous system wrap around axons to form the myelin sheath, while oligodendrocytes serve this role in the central nervous system.
- Damaged or demyelinated axons can lead to neurological impairments, including decreased nerve conduction and muscle weakness.
- Myelin sheath formation begins during fetal development and continues through early childhood, influencing the speed of neural development.
- Research on myelin sheath regeneration holds promise for potential therapies to treat conditions like multiple sclerosis and spinal cord injuries.
- The formation of the myelin sheath requires the precise coordination of multiple cellular processes, including the synthesis and deposition of myelin proteins.
