The spinal nerves further divide into anterior and posterior rami. Muscle and skin innervation to the extremities originates from the anterior rami and its nerve plexuses of interconnected sensory ...
An international team of scientists has uncovered a fascinating piece of the evolutionary puzzle: how the ventral nerve cord, a key component of the central nervous system, evolved in ecdysozoan ...
Summary: A study analyzing Cambrian fossils uncovered that the ancestral ecdysozoan likely had a single ventral nerve cord, challenging long-standing views about the evolution of these structures.
Magnetic resonance imaging (MRI) showed long segment hyperintensity in the thoracic spinal cord ... of cranial nerves and upper extremities were normal. Five minutes later, she complained of acute ...
Spinal stenosis is a narrowing of the spinal canal that causes compression of the spinal cord and/or nerve roots. Resulting pain and numbness (in the hands, arms, legs, and/or feet) can vary depending ...

New fossil discovery sheds light on the early evolution of animal nervous systems Groundbreaking research uncovers the origins of the ventral nerve cord in early moulting animals Date: January 10 ...
Cambrian fossils reveal ventral nerve cord structure in early ecdysozo Single ventral nerve cord identified as ancestral nervous system desig Paired nerve cords evolved later, aiding segmentation and ...
Here, we address the emerging role of medial OFC, amygdala, and ventral tegmental area projections to the ventral striatum (VS) in OCD pathophysiology. The VS receives strong innervation from these ...

If nerves are compressed by collapsing spinal bones, there can also be arm or leg weakness ... Surgical options for neck arthritis include: Anterior cervical discectomy and fusion (ACDF): A surgery ...
“We found that the motoneurons for the illicium are present in the dorsolateral zone of ventral horn at the medullo-spinal ... occipital nerve. The study found that the dorsal ramus of the ...
