Study Notes
Learning Objectives for Pathology of the Peripheral Nervous System
- Identify the learning objectives for the series on pathology of the peripheral nervous system
Processes in the PNS
- The process of retrograde transport occurs in the PNS, where materials are transported from the axon terminal back to the cell body
Injuries Affecting the PNS
- One type of injury affecting the PNS mentioned in the learning objectives is a peripheral nerve injury
Limitations of Peripheral Nerve Biopsy
- A limitation mentioned in the learning objectives is that peripheral nerve biopsy is not feasible in a live veterinary patient due to the potential for causing further nerve damage
Neuromuscular Junction
- Acetylcholine esterase plays a key role in the neuromuscular junction by breaking down acetylcholine, a neurotransmitter, after it has transmitted a signal
Myelination in the PNS
- The main function of the myelin sheath in the peripheral nervous system is to insulate and facilitate the transmission of nerve impulses
- Axons outside of the central nervous system are myelinated by Schwann cells
- The nodes of Ranvier in myelinated axons are the gaps in the myelin sheath where saltatory conduction occurs, allowing for rapid transmission of nerve impulses
