The efferent limb of a myotatic reflex includes a(n):: (A) Anterior horn motor neuron, (B) Lateral horn visceromotor nucleus., (C) Muscle spindle., (D) Preganglionic sympathetic neuron
Answer is A. The myotatic reflex is a monosynaptic, sretch reflex. The efferent limb consists of the axon of an anterior horn alpha motor neuron that innervates striated muscle fibers (effector). The afferent limb consists of a muscle spindle (receptor) and an Ia fiber (axon) of a spinal ganglion neuron.
