Epiphyses
Epiphyses
Epiphyses (pronunciation: /ɪˈpɪfɪsiːz/) are the rounded ends of long bones in the human body. They are located at the site where the bone articulates with other bones, forming a joint.
Etymology
The term "epiphysis" is derived from the Greek word "epiphysis" which means "to grow upon". This is in reference to the way the epiphyses grow on the ends of long bones during development.
Function
The primary function of the epiphyses is to aid in the articulation of joints. They are covered with a layer of articular cartilage which helps to reduce friction and absorb shock during movement. The epiphyses also play a crucial role in bone growth during childhood and adolescence. They contain the epiphyseal plate, also known as the growth plate, which is responsible for longitudinal growth of the bone.
