Thekey differencebetween innervated and denervated muscles is based on the nervous supply received by the muscles.虽然神经支配的肌肉通过神经协调介导了良好的神经供应,但肌肉不受神经供应,因此失去了肌肉功能。
Muscular movements have a neurogenic property. Therefore, muscular movements are mediated by the nerve signals that pass through them in order to ensure their appropriate functionality. In any failure where the nervous supply is blocked or inhibited,muscle dystrophy发生肌肉的变性。

什么是神经支配的肌肉?
肌肉的支配muscles that have a good supply of nerves. Therefore, their nervous coordination is well manipulated. A muscle is innervated through the use of a single motor axon. In some cases, more than one muscle can be innervated by a single axon. However, when this phenomenon takes place, all the fibres innervated through one axon is termed as a motor unit. Eventually, these motor units form thick fibres that can perform muscular movements. Muscle innervation is mediated by the presence ofneurotransmitters将这些神经源信号带到肌肉。他们在神经肌肉连接处分泌,以使信号通过产生的动作电位.
The process of muscle innervation is essential to maintain the integrity of the muscles and for the accurate functioning of muscles. Failure of this process results in muscle denervation, leading to muscular dystrophy and muscle degeneration.
什么是被剥夺的肌肉?
Denervated muscles are muscles that have lost the nervous supply through a process called denervation. Denervation may take place through injury, inborn disorders, or due to post-surgery complications. Following denervation, muscles lose the nervous communication that provides the signals for coordination of movements. Therefore, this process leads to muscle dystrophy, causing physiological disorders.
In some cases, denervated muscles can be present due to inborn genetic errors such as Amyotrophic lateral sclerosis (ALS) or following certain disorders such as Post-polio syndrome. The severity of denervated muscles depends on the location of denervation. In certain cases, denervated muscles can lead to the complete dysfunction of a particular organ or tissue.
Denervated muscles usually undergo muscular atrophy and muscle degeneration. This, in turn, leads to the reduction of muscle mass, muscle size and muscle quantity. It also affects muscular movements of contraction and relaxation. Denervated muscles can be detected through Magnetic resonance imaging scans or through ultrasonography.
神经支配和永无止境的肌肉之间有什么相似之处?
- Innervated and denervated muscles are two types of muscles.
- Both are based on the nervous supply to muscles.
- They focus on aspects of muscle coordination.
What is the Difference Between Innervated and Denervated Muscles?
肌肉在调节高层生物的运动和结构中起着重要作用。神经支配和剥夺的肌肉都涉及对肌肉的神经供应的概念。然而,虽然神经支配的肌肉是指获得良好神经供应的肌肉,但被剥离的肌肉是指失去神经供应的肌肉。因此,这是神经和永无止境的肌肉之间的关键区别。由于这种差异,每种肌肉类型的质量各不相同。
The below infographic lists the differences between innervated and denervated muscles in tabular form.
概括– Innervated vs Denervated Muscles
Innervated muscles refer to the muscles that have a good supply of nerves, while denervated muscles refer to muscles that do not have a good supply of nerves. Innervation takes place under physiological conditions, while denervation takes place following an injury, a post-surgery complication or due to an inborn metabolic or genetic error. However, following denervation, there is a possibility of reinnervation depending on the severity level. Thus, this is the summary of the difference between innervated and denervated muscles.
