  Peroneus longus muscle - Wikipedia, the free encyclopedia
The muscle peroneus longus (also known as fibularis longus) is a superficial muscle in the human leg, and acts to evert and plantar flex the ankle.
Peroneus longus becomes a tendon that goes posterially around the lateral malleolus of the ankle, then continues under the foot to attach to the 1st metatarsal.
It is a muscle of the lateral compartment of the leg and is innervated by the superficial peroneal nerve.

 Journal of Bone and Joint Surgery: peroneus quartus muscle, The
The peroneus quartus muscle is one of a group of accessory peroneal muscles present in man. It is said to have been first described by Otto in 1816 and was studied in depth in 1923 by Hecker,1 who estimated its incidence to be 13% in the general population.
Sobel, Levy and Bohne2 described the anatomical variations of the muscle in a cadaver study on 124 legs with particular reference to the origins and insertions of the different anomalous muscles in the lateral compartment and suggested that these should all be referred to as variants of the same muscle, the peroneus quartus.
When peroneus quartus arose from peroneus longus, its tendon passed separately in the retromalleolar groove and inserted into the retrotrochlear eminence of the calcaneum which was raised to 4 mm.

We were concerned that the peroneus longus muscle, a plantar flexor not innervated by the tibial nerve, might contribute to the force output during voluntary contractions but not electrically evoked contractions, thereby creating a disparity in the size of the active muscle mass in the 2 protocols.
The EMG activity recorded from the peroneus longus and tibialis anterior muscles during the voluntary exercise protocol was expressed as a percentage of the activity recorded previously during a maximal voluntary contraction.
It is possible that the peroneus longus and soleus muscles were activated along with the gastrocnemius muscle during the voluntary exercise protocol, whereas only the gastrocnemius muscle was active during the TENS protocol.

The peroneus tertius arises from the lower third of the fibula (lower leg bone) and the adjacent interosseous membrane and continues downward and slightly forward, across the ankle, where it tapers into a narrow, flat tendon that passes over the extensor digitorum brevis and inserts into the fifth metatarsal bone (little toe).

M) decreased the peak force of sub-tetani in the slow-contracting soleus muscle and increased the peak force of sub-tetani in the fast-contracting peroneus longus muscle.
The decrease in the peak force of sub-tetani in the soleus muscle was due to defusion of the individual twitches caused by a shortening of their time course.
We concluded that all the effects of R,S-salbutamol on guinea-pig skeletal muscles are due to the activity of the R-enantiomer.

Clonus occurs because the chronictonic shortening of the muscle spindle predisposes hyperreflexive stretch reflexes.
In spastic muscles, the hyperexcitability of the alpha or gamma motor neurons are such that the stretch reflex and subsequent synchro-nous muscle spindle firing begin to cycle discharges of the alpha motor neurons and stretch reflex contractions.
Conventional rehabilitation methods were used to suppress the undesirable hyperactivity of the peroneus longus muscle along with the feedback.
