motor root

Immediately adjacent to the sensory root, a smaller motor root emerges from the pons at the same level.

Upon reaching the facial canal, it joins with the motor root of the facial nerve at the geniculate ganglion.

The ophthalmic and maxillary consist exclusively of sensory fibers; the mandibular is joined outside the cranium by the motor root.

In each vertebrate segment the 'reflex arc' is based upon two neurons: the afferent sensory root and the efferent motor root.

In anatomy and neurology, the ventral root (or anterior root) is the efferent motor root of a spinal nerve.

The motor root carries presynaptic parasympathetic nerve fibers (GVE) that terminate in the ganglion by synapsing the postsynaptic fibers traveling to target organs.

They receive an excitatory collateral from the alpha neuron's axon as they emerge from the motor root, and are thus "kept informed" of how vigorously that neuron is firing.

Like the lateral pterygoid, and all other muscles of mastication the medial pterygoid is innervated by the anterior root (motor root) of the mandibular branch of the trigeminal nerve (V).

From the geniculate ganglion the taste fibers continue as the intermediate nerve which goes to the upper anterior quadrant of the fundus of the internal acoustic meatus along with the motor root of the facial nerve.

The motor root runs in front of and medial to the sensory root, and passes beneath the ganglion; it leaves the skull through the foramen ovale, and, immediately below this foramen, joins the mandibular nerve.

Direct infiltration of the nerve roots is also observed, mostly from the dorsal roots (the afferent sensory root of the spinal nerve) than the ventral roots (the efferent motor root of a spinal nerve).
