cervical enlargement
The cervical enlargement is a thickened area of the spinal cord in the neck region, specifically between the third cervical (C3) and first thoracic (T1) vertebrae. This area of the spinal cord is responsible for transmitting signals to and from the upper limbs.
The cervical enlargement is larger than other regions of the spinal cord due to the presence of a greater number of motor neurons that control the upper limbs, as well as sensory neurons that receive sensory information from the upper limbs. The cervical enlargement is also where the brachial plexus, a network of nerves that supply the upper limbs, originates from.
Damage to the cervical enlargement can result in neurological deficits affecting the upper limbs, such as weakness or paralysis, altered sensation or loss of sensation, and changes in reflexes. Common causes of cervical enlargement injury include spinal cord trauma, disc herniation, spinal stenosis, or tumors. Treatment for cervical enlargement injuries may include medication, surgery, physical therapy, or a combination of these approaches depending on the severity and underlying cause of the injury.
