There is no junction. Motor neurons are riddled throughout the muscle spindles. Every muscle spindle has a nerve supply or it would not function. think about the way capilaries infiltrate mucles, it's pretty finite. when you are talking about the neurons you are talking about a finite thing, there are billions of them in your body.
The neuromuscular junction is the point where the motor neuron terminates on the skeletal muscle. It is a synapse, or gap.
it is the motor unit

neuromuscular junction
Includes the axon terminal of a motor neuron plus the motor end plate of a muscle fiber. Is where the axons of motor nerves meet the muscle & transmit messages from the brain which cause the muscle to contract & relax.
neuromuscular junction
Sensory Neuron sends info to the brain while the motor sends the info to the muscle fiber.The motor neurone sends a signal from the CNS or PNS to the effector muscle or gland. Therefore the motor neurone sends a signal TO the muscle fibre.
Neuromuscular Junction
Each muscle cell is only innervated by a single motor neuron, but each motor neuron innervates any number of muscle cells. When an action potential travels down the axon of an alpha motor neuron, it will depolarize several muscle cells at the same time, a phenomenon known as summation.
Neuromuscular junction (NMJ)
A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.A Motor neuron is a neuron that carries impulses from the spinal cord to muscle cells.
The motor neuron and the muscle fiber approach each other.
