Nerve anatomy is a crucial aspect of the musculoskeletal system, playing a vital role in transmitting signals between the brain, spinal cord, and muscles, enabling movement, sensation, and reflexes. In the limbs, major nerves originate from nerve plexuses such as the brachial plexus in the upper limb and the lumbosacral plexus in the lower limb. Key nerves in the upper limb include the median, ulnar, and radial nerves, while the lower limb consists of the femoral, sciatic, tibial, and common peroneal nerves. These nerves travel through muscles, joints, and other soft tissues, branching off to provide motor control and sensory feedback to specific regions. Injury or entrapment of these nerves can lead to weakness, numbness, or pain, making an understanding of nerve anatomy critical for diagnosis and treatment in clinical practice.
The sonoanatomy of nerves is distinct and highly valuable for assessing nerve health and identifying potential pathologies. On ultrasound, nerves typically appear as hypoechoic structures with a characteristic “honeycomb” pattern in the transverse view, due to the presence of nerve fascicles surrounded by echogenic connective tissue. This honeycomb structure makes nerves easy to differentiate from nearby muscles, tendons, and blood vessels. Longitudinally, nerves show up as hypoechoic, linear bands, often traveling alongside major arteries and veins. Ultrasound is highly effective in visualizing peripheral nerves like the median, ulnar, and radial nerves in the upper limb, or the sciatic, femoral, and tibial nerves in the lower limb. This real-time imaging technique is essential for identifying nerve entrapments, compressions, or injuries, as well as guiding interventions such as nerve blocks or injections. Mastering nerve sonoanatomy helps clinicians assess and manage conditions like carpal tunnel syndrome, cubital tunnel syndrome, or sciatica with precision.
