Nilkan peroneus longus?
Vastaus:
The peroneus longus, also known as the fibularis longus, is a muscle located in the lateral compartment of the leg. Here’s an overview of its anatomy, function, and relevance:
### Anatomy
- Origin: It originates from the upper two-thirds of the fibula and the intermuscular septa.
- Insertion: It inserts into the base of the first metatarsal bone and the medial cuneiform bone of the foot.
- Nerve Supply: It is innervated by the superficial fibular nerve (also known as the superficial peroneal nerve).
### Function
- The primary actions of the peroneus longus include:
- Eversion of the foot (turning the sole outward).
- Plantarflexion of the ankle (pointing the toes).
- Supporting the arches of the foot, particularly the lateral arch.
### Clinical Significance
- Injuries to the peroneus longus can lead to instability in the ankle and foot, as well as conditions like ankle sprains or tendonitis.
- Given its role in ankle stability, alterations in the function of this muscle can contribute to various foot and ankle pathologies.
