===Myotatic reflexes===

The myotatic or muscle [[stretch reflex]]es (sometimes known as ''deep tendon reflexes'') provide information on the integrity of the [[central nervous system]] and [[peripheral nervous system]]. This information can be detected using [[Electromyography|electromyography (EMG)]].<ref name=":1">{{Cite journal |last1=Tsuji |first1=Hironori |last2=Misawa |first2=Haruo |last3=Takigawa |first3=Tomoyuki |last4=Tetsunaga |first4=Tomoko |last5=Yamane |first5=Kentaro |last6=Oda |first6=Yoshiaki |last7=Ozaki |first7=Toshifumi |date=2021-01-27 |title=Quantification of patellar tendon reflex using portable mechanomyography and electromyography devices |journal=Scientific Reports |language=en |volume=11 |issue=1 |pages=2284 |doi=10.1038/s41598-021-81874-5 |issn=2045-2322 |pmc=7840930 |pmid=33504836 |doi-access=free|bibcode=2021NatSR..11.2284T }}</ref> Generally, decreased reflexes indicate a peripheral problem, and lively or exaggerated reflexes a central one.<ref name=":1" /> A stretch reflex is the contraction of a muscle in response to its lengthwise stretch.
* [[Biceps reflex]] ([[cervical spinal nerve 5|C5]], [[cervical spinal nerve 6|C6]])
* [[Brachioradialis reflex]] (C5, C6, [[cervical spinal nerve 7|C7]])
* [[Extensor digitorum reflex]] (C6, C7)
* [[Triceps reflex]] (C6, C7, [[cervical spinal nerve 8|C8]])
* [[Patellar reflex]] or knee-jerk reflex ([[lumbar spinal nerve 2|L2]], [[lumbar spinal nerve 3|L3]], [[lumbar spinal nerve 4|L4]])
* [[Ankle jerk reflex]] (Achilles reflex) ([[sacral spinal nerve 1|S1]], [[sacral spinal nerve 2|S2]])

While the reflexes above are stimulated mechanically, the term [[H-reflex]] refers to the analogous reflex stimulated electrically, and [[tonic vibration reflex]] for those stimulated to vibration.
