Final answer:
The term that represents the transfer of energy across joints to support voluntary movement is the neuromuscular junction.
Step-by-step explanation:
The term that represents the transfer of energy across joints to support voluntary movement is neuromuscular junction. The neuromuscular junction is the area where a nerve ending and a muscle fiber come into close contact. When a nerve impulse reaches the neuromuscular junction, it triggers the release of neurotransmitters that cause the muscle to contract, resulting in movement.
