We describe procedures for repeated administration of inhibitors of muscarinic signaling to the levator auris longus (LAL) muscle of young adult mice and for subsequent immunostaining of its neuromuscular junctions (NMJs) in wholemounts. The LAL muscle has unique advantages for revealing in vivo pharmacological effects on NMJs.

The protocol described in this paper uses the mouse levator auris longus (LAL) muscle to record spontaneous and nerve-evoked postsynaptic potentials (current-clamp) and currents (voltage-clamp) at the neuromuscular junction. Use of this technique can provide key insights into mechanisms of synaptic transmission under normal and disease conditions.
FAQs
Its tendon travels behind the lateral malleolus and then beneath the foot before reaching the medial cuneiform and base of the first metatarsal. This course allows contraction to influence structures on the underside and medial side of the foot, helping produce eversion and plantarflexion while also contributing to transverse arch support during movement.
Contraction helps support the transverse arch by applying muscular tension through the tendon beneath the foot toward its attachment near the medial cuneiform and first metatarsal. This support complements its movement-producing actions and helps the foot remain positioned for balance and efficient gait rather than functioning only as a joint mover.
Eversion turns the sole outward, while plantarflexion points the foot downward. Together, these actions help position the foot during movement. Because the muscle also supports the transverse arch, its activity contributes to maintaining foot stability as the body balances and progresses through gait.
Functional analysis should connect three features: the muscle fibers arise mainly from the upper lateral fibula, the tendon passes behind the lateral malleolus and beneath the foot, and the tendon attaches near the first metatarsal and medial cuneiform. Relating origin, route, and attachment explains how contraction produces the described foot actions and arch support.
A clinical assessment can focus on the muscle’s expected contributions to foot eversion, plantarflexion, transverse arch support, balance, and gait. Comparing these functions with observed movement may help organize the examination of ankle injuries or tendon disorders. The anatomical tendon route is especially relevant when interpreting problems involving the lateral ankle or underside of the foot.
The muscle is relevant because its actions combine movement and stabilization. Sports science can consider how eversion, plantarflexion, arch support, balance, and gait interact during physical activity. In clinical and research contexts, its anatomy provides a framework for studying ankle injuries and tendon disorders that may affect foot positioning or movement efficiency.
