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.
