What does a motor unit consist of?

A motor neuron and all the muscle cells it stimulates
Multiple motor neurons connected to a single muscle cell
A single muscle cell and its corresponding blood supply
A group of muscle cells that function independently

The correct answer is: A motor neuron and all the muscle cells it stimulates

A motor unit consists of a motor neuron and all the muscle cells it stimulates. This is because the motor neuron is responsible for sending nerve impulses to the muscle cells, causing them to contract. Option B is incorrect because it describes a neuromuscular junction, where multiple motor neurons can connect with a single muscle cell. Option C is incorrect because it does not include the motor neuron, which is a crucial component of a motor unit. Option D is incorrect because motor units are made up of closely connected muscle cells that work together to produce coordinated movements, rather than functioning independently.
