What term describes the loss of sensation and voluntary muscle movements due to nerve injury?

The term that describes the loss of sensation and voluntary muscle movements due to nerve injury is paralysis. This condition occurs when there is damage to the nerves that transmit signals from the brain to the muscles, which can result from various factors, such as injury, disease, or conditions affecting the central nervous system. When paralysis occurs, it can affect a muscle group partially or completely, leading to the inability to move that part of the body, as well as loss of sensation in the affected areas.

Other terms listed refer to different medical concepts. A lesion refers to any abnormal tissue change, which could occur in various conditions but does not specifically refer to loss of movement or sensation. Pyoderma denotes a bacterial skin infection, which is unrelated to nerve function. Myalgia indicates muscle pain, which may be associated with various conditions, but does not capture the complete loss of sensation and movement that characterizes paralysis. Thus, paralysis is the precise term for the described condition.
