Centrioles are found in animal cells, but not plant cells. They help to organize the assembly of microtubules during cell division. Centrioles are found within cell structures known as centrosomes. During cell division, the centrosome and centrioles replicate and migrate to opposite ends of the cell.
The peroneus brevis tendon and peroneus longus tendon merge in a sheath behind the ankle. When the corresponding muscles are flexed, the tendons slide inside the sheath. Symptoms of injury to the peroneus brevis tendon include swelling as well as pain at the base of the little toe or in the outer ankle area.
Tendon Rupture. When a tendon ruptures it can be extremely painful and cause a disability of the foot that then subsequently causes damage to the ankle joints. The tendons in the ankle include: The peroneals (peroneus brevis, peroneus longus,) anterior tibialis, posterior tibialis, and Achilles tendon.
