The main difference between both innervated and denervated muscles depends on the supply of nerves that is perceived by the muscles. The denervated muscles lack a nerve supply, hence their muscular functionality is lost. On the other hand, the innervated muscles possess a good supply of nerves, brought about by mediation via the coordination of nerves.
Innervated Muscles
- When nerves enter the muscle fibres, it innervates the fibres. To innervate is to supply nerves with something in addition to also energizing it
- All nerve fibres that supply the muscles are intact
- Innervation of muscles through a single motor axon, in a few events, more than one muscle can get innervated
- The process is mediated by the neurotransmitters carrying neurogenic signals towards the muscles
Denervated Muscles
- Denervation refers to the loss of nerve supply, irrespective of the cause
- It could be as a result of a symptom of a disorder or could be caused by injury
- It can be used as a surgical method to reduce main negative symptoms as that of renal denervation
- It can have adverse harmful side effects, such as increased risk of infection and even tissue dysfunction
