Nerve-muscle connection. Light micrograph of neuromuscular synapses,the connection points between a motor neurone axon (nerve fibre,centre and upper centre) and the skeletal muscle fibres that it controls (pale tissue bands). The end of a motor neurone axon divides into branches,each one terminating on a different muscle fibre. A single axon thereby has the ability to activate several hundred muscle fibres. The end of each branch divides to form a cluster of small swellings (dark speckles) known as motor end plates on the muscle fibre surface. These activate and inhibit muscle activity.
