	Muscle Associations : Ipsilateral association
		The descending reticular formation is mostly an ipsilateral system of double innervating to the organs and muscles: the lateral reticulo spinal tract reaches the preganglionic autonomic fibers and the medial reticulo spinal tract reaches the lower motor neurons (see Figure 1-7).
		The tensor of the fascia lata arises from the outer lip of the crest of the ilium and the anterior superior iliac spine, and it follows the outer side of the thigh to become the ilio-tibial band that inserts on the external tuberosity of the tibia.
		The main activity of these three muscles is to stabilize the hip joint in the standing position and to support the body when standing on one limb.

		The "extensor hallucis longus" are muscles used in extending the toe; the "flexor hallucis longus" are used in flexing it and moving it to the side.

		Purpose: Extensor hallucis longus-muscle paresis or paralysis as an isolated injury has been one of the complications in patients who have undergone different procedures in the proximal part of the leg, such as proximal tibial and fibular osteotomy and placement of external fixators, tibial traction pins, and proximal locking screws in tibial nailing.
		The branches innervating the extensor hallucis longus muscle from the fibular side were noted to have a closer relation with the fibular periosteum than those entering the muscle from the tibial side or the anterior edge.
		The high-risk zone for iatrogenic injury to the muscular branch of the extensor hallucis longus was located between 5.9 ± 1.7 and 10.9 ± 1.7 cm inferior to the most distal palpable point of the fibular head.

	Discharge behaviour of single motor units during maximal voluntary contractions of a human toe extensor -- Macefield et ...
		We conclude that single motoneurones supplying the extensor hallucis longus, a muscle comprised primarily of slow twitch muscle units, show little adaptation in firing with fatigue, suggesting that a progressive reduction in firing rate is not an invariable consequence of the fatigue associated with sustained maximal voluntary contractions.
		The present data indicate that the maximal volitional firing rates of extensor hallucis longus are closer to those of a slow postural muscle, although perhaps not as slow as soleus.
		We conclude that single motoneurones supplying the extensor hallucis longus muscle show no significant adaptation in firing rate or variability during the fatigue associated with a maximal voluntary contraction, suggesting that progressive adaptation in firing behaviour is not an invariable consequence of sustained maximal voluntary contractions.

	Variations in the insertion of the extensor hallucis longus muscle.
		Reports that describe abnormalities of the muscles and tendons of the leg and foot are important with regard to understanding the function of the lower limb and correlating these abnormalities with the clinical aspects.
		Pattern I (65%): the extensor hallucis longus muscle had a single tendinous insertion on the dorsal aspect of the base of the distal phalanx of the big toe.
		It is suggested that the presence of these variations in the insertion of the extensor hallucis longus muscle may have a role in explaining its association with hallux valgus.

	Palsy of the deep peroneal nerve after proximal tibial osteotomy - Wheeless' Textbook of Orthopaedics
		Iatrogenic, isolated weakness or paralysis of the extensor hallucis longus muscle is a common complication in patients who have had a proximal tibial and fibular osteotomy.
		Of forty-six motor nerves that were identified, eight entered the muscle from the lateral side in an area seventy to 150 millimeters distal to the fibular head; all of them ran close to the fibular periosteum.
		We suggest that, in some patients, the nerve supply to the extensor hallucis longus is at high risk for injury during a tibial osteotomy because of the proximity of the bone to the motor branches.

		We conclude that force exerted at the tendon at the lengthened end of a muscle is higher because of the extra load imposed by myofascial force transmission on parts of the muscle belly.
		This is mediated by changes of the relative position of most parts of the lengthened muscle with respect to neighboring muscles and to compartment connective tissues.
		As a consequence, muscle relative position is a major codeterminant of muscle force for muscle with connectivity of its belly close to in vivo conditions.
