Afireman 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 the left section of his lower body sensation in the left section of his upper body

In this case, the fireman has a damage in the left ventral root of the firsts thoracic vertebrae.

The ventral root is the efferent neuron, which carry signals away from the central nervous system. Ventral root neuron present in the T1 (thoracic 1) vertebrae carry signals to the upper extremities. So, the damage to the left ventral root of his first thoracic vertebrae would result in loss of motor function of upper extremities.

Hence, the correct answer is Movement in his upper extremities.
