A functional assessment of the neuromuscular junction (NMJ) can provide essential information on the communication between muscle and nerve. Here we describe a protocol to comprehensively evaluate both the NMJ and muscle functionality using two different muscle-nerve preparations, i.e. soleus-sciatic and diaphragm-phrenic.

Source: Charalambos, C. C., et al. Bilateral Assessment of the Corticospinal Pathways of the Ankle Muscles Using Navigated Transcranial Magnetic Stimulation. J. Vis. Exp. (2019)This video demonstrates the method to assess corticospinal pathways of the leg muscles using transcranial magnetic stimulation (TMS). Rest and active muscle responses are recorded from one brain hemisphere to evaluate the contralateral corticomotor function of leg muscles.

We present a protocol to assess changes in neuromuscular function. Percutaneous electrical nerve stimulation is a non-invasive method that evokes muscular responses. Electrophysiological and mechanical properties of these responses permit the evaluation of neuromuscular function from brain to muscle (supra-spinal, spinal and peripheral levels).

Here, we present a modification of a previously reported method that allows for the isolation of high quality and purified mitochondria from smaller quantities of mouse skeletal muscle. This procedure results in highly coupled mitochondria that respire with high function during microplate based respirometirc assays.
FAQs
Its high proportion of slow-twitch muscle fibers supports sustained, fatigue-resistant contraction. This characteristic allows the soleus to contribute for extended periods while the body maintains an upright position or performs low-intensity movements. In biology and exercise science, this fiber composition helps explain why the muscle is important for postural control as well as repeated, low-demand activity.
When the soleus contracts, its connection to the heel through the Achilles tendon transfers the muscle’s force to the ankle. This arrangement supports plantarflexion, which raises the heel and points the foot downward. Studying this muscle-tendon connection helps relate muscle contraction to larger movements involved in standing and walking.
The soleus contributes to balance by helping stabilize the body at the ankle while a person stands or moves. Its sustained activity supports control of the lower limb during posture and locomotion, rather than serving only brief, forceful actions. This makes the muscle relevant to biological studies of body stability and impaired mobility.
Because the soleus participates in prolonged posture and low-intensity movement, it provides a useful context for examining how muscle function relates to repeated or sustained activity. Research can connect its fatigue-resistant behavior with changes in locomotion, balance, or mobility. These relationships help place muscle adaptation within broader biological studies of movement and physical function.
Researchers may focus on the soleus when investigating calf strain, tendon disorders, or impaired mobility. Its contribution to ankle movement, heel raising, posture, and walking makes it relevant to understanding how these conditions affect function. Studying the muscle can therefore help connect a local calf or tendon problem with broader changes in movement and stability.
Soleus research can show how a fatigue-resistant calf muscle supports standing, walking, ankle movement, and balance over time. Its position beneath the gastrocnemius and connection to the heel also provide anatomical context for interpreting lower-leg function. In exercise science and biology, these features support investigations of movement, muscle adaptation, and reduced mobility.
