A fireman injures the left ventral root of his first thoracic vertebrate when he falls off a fire engine ladder. What major functions could be lost due to his injury? movement in his upper extremities sensation in his lower extremities control of his trunk stability sensation in the left section of his upper body.

Answer :

The firefighter in this case had a fracture in the left ventral root of the first thoracic vertebrae.

Efferent neurons, which convey impulses away from the central nervous system, are found in the ventral root. T1 (thoracic 1) vertebral ventral root neurons provide impulses to the upper extremities.

As a result of the injury to the left ventral root of his first thoracic vertebrae, he would lose upper extremity motor function. As a result, the right response is Movement in his upper extremities.

Thoracic or rib cage nerves (T1 through T12) send impulses to the torso and some regions of the arms.

Individuals with T1-T8 injuries typically lose control of their upper torso, restricting trunk movement and feeling due to a loss of abdominal muscle function.

This can have an impact on both balance and proprioception (where your body is in space)
