Motor nerve Myelinated GS<unk>  fiber leaving cell body of motor neuron to form a neuromuscular junction The<unk> s of motor neurons are involved in muscle control, both skeletal and smooth muscle. The cell body of the motor neuron is connected to a single, long axon and several shorter dendrites projecting out of the cell body itself. This axon then forms a neuromuscular junction with the effectors. The cell body of the motor neuron is satellite-shaped. The motor neuron is present in the grey matter of the spinal cord and medulla oblongata, and forms an electrochemical pathway to the effector organ or muscle. Besides motor nerves, there are<unk>  sensory nerves that often serve to adjust the sensitivity of the signal relayed by the<unk>  sensory nerve. Types There are three types of<unk>  fibers: general somatic<unk>  fibers (GSE), general visceral<unk>  fibers (GVE) and special visceral<unk>  fibers (SVE). Subtypes of general somatic<unk>  fibers include: alpha motor neurons (α) – these target extrafusal muscle fibers, and gamma motor neurons (γ) that target intrafusal muscle fibers. Beta motor neurons target both types of muscle fiber and there are two types known as static and dynamic.
