Stretch Reflex
|
1. Homonymous activation: Monosynaptic activation of homonymous alpha motoneurons by Group Ia afferents.
2. Synergistic excitation: Monosynaptic activation of motoneurons innervating synergistic muscles 3. Antagonist inhibition: Disynaptic inhibition (synapse on inhibitory interneurons) of motoneurons that innervates antagonist muscles (reciprocal innervation) |

|
Muscle tone
|
Resistance of a muscle to active or passive stretch
|
|
|
Inverse myotatic reflex
|
Golgi tendon organ stimulation. Group Ib fibers disynaptically inhibit homonymous motoneuron pool, causing relaxation, and disynaptically exciting motoneurons of antagonists.

Clasp-Knife Reflex
|
Dramatic demonstration of Golgi tendon reflex in a hypertonic or spastic muscle. Initial resistance followed by rapid flexion.
