(tib-ē-ā'lis an-tēr'ē-ŏr mŭs'ĕl)
Medial muscle of anterior (dorsiflexor) compartment of leg; origin, upper two thirds of lateral surface of tibia, interosseous membrane, and overlying crural fascia; insertion, medial cuneiform and base of first metatarsal; action, dorsiflexion and inversion of foot; provides dynamic support of longitudinal and transverse arches of foot; nerve supply, deep peroneal.

tibialis anterior muscle

Leg muscle. Origin: lateral side of proximal tibia. Insertion: medial side of cuneiform bone, base of metatarsal 1. Nerve: deep peroneal (L4-L5). Action: inverts and dorsiflexes foot.

In our study, tibialis anterior muscles of malnourished post-weaning rats were analyzed after two months of nutritional recovery, but a reduction in muscle mass was still demonstrated.
Another view of the tibial bone exposure covered with the 1) the medial gastrocnemius flap, 2) the tibialis anteriorflap (2 a: split part of the tibialis anterior muscle, and 2 b: the basic part of the tibialis anterior muscle) and 3) the distally based hemisoleus flap
Caption: Figure 1: (a) Longitudinal section on the anterolateral aspect of left upper leg superior to the site of muscle hernia showing intact echogenic fascia with underlying tibialis anterior muscle.

Foot drop or tibialis anterior muscle weakness is caused by multiple neurological conditions such as brain lesion (3,4), spinal cord disease (5), multiple sclerosis (6), common fibular nerve mononeuropathy (2) and degenerative lumbar vertebral diseases (7,8,9,10,11).
When non-progressive isolated fasciculations of the tibialis anterior muscle, it has to been examined the 5th lumbar root and the deep peroneal nerve, as localizer sensory symptoms may be absent (4), and to rule out any more diffuse neurogenic processes.
A standardized surgical lesion was performed using a 5 mm diameter biopsy punch blade, creating an approximately 60 [micro]L volume full thickness defect in the midbelly region of the tibialis anterior muscle (Figures 2(a)-2(c)).
Parthenolide treatment could effectively preserve the body weight, improve the mass of gastrocnemius and tibialis anterior muscles, and alleviate tumor burden.

For example, within the highest CK-2017357 plasma concentration range evaluated in the study (i.e., from > 12 mcg/mL up to 25.6 mcg/mL), the mean placebo-corrected percent increase in the peak force developed by the tibialis anterior muscle during stimulation at a frequency of 12.5 Hz was 13.7% (p < 0.001).
