How Do You Spell MUSCULUS PERONEUS TERTIUS?

1. The term "musculus peroneus tertius" refers to a specific muscle found in the lower leg. It is also known by its alternative name, the "fibularis tertius muscle." This muscle is situated on the anterior (front) side of the leg and is one of the four muscles within the peroneal group.

   The musculus peroneus tertius originates from the lower two-thirds of the fibula, which is one of the two bones in the lower leg. It then inserts onto a tendon on the base of the fifth metatarsal bone in the foot. This muscle is predominantly involved in the dorsiflexion and eversion of the foot. Dorsiflexion refers to the movement of lifting the toes and foot upwards, while eversion refers to the movement of tilting the sole of the foot outward.

   The musculus peroneus tertius is innervated by the deep peroneal nerve, which arises from the common peroneal nerve. This innervation is responsible for providing the necessary signals for the muscle to contract and perform its respective movements.

   Overall, the musculus peroneus tertius plays a significant role in ankle and foot movement, particularly in activities that involve raising the foot and turning it outward.

2. Origin, in common with extensor digitorum longus; insertion, dorsum of base of 5th metatarsal bone; nerve supply, deep branch of peroneal; action, assists in dorsal flexion of foot.
