This write-up covers the anatomical significance, motor and sensory functions, clinical presentation of injuries (such as Klumpke’s Palsy), and the mechanism of Thoracic Outlet Syndrome.
Together, these two roots contribute fibers to the , specifically forming the Inferior Trunk . Because of their low position in the neck and their path over the first rib, they are mechanically vulnerable to compression and traction injuries. This write-up covers the anatomical significance, motor and
Issues at these levels, such as (pinched nerves), often mimic ulnar neuropathy (cubital tunnel syndrome) because both affect the inner hand. Differentiating C8–T1 Radiculopathy from Ulnar Neuropathy Issues at these levels, such as (pinched nerves),
These nerves are vital for motor control of the long finger flexors and, critically, the intrinsic muscles of the hand . As they emerge, the anterior primary rami of
The sensory distribution of C8 and T1 covers the medial aspect of the upper limb.
As they emerge, the anterior primary rami of C8 and T1 join to form the inferior (lower) trunk of the brachial plexus.
