Pronunciation: [ɛpˈɪfəsˌɪs] (IPA) 
The word "epiphysis" (/ɪˈpɪfɪsɪs/) is spelled as it sounds - each letter corresponds to a specific sound in the International Phonetic Alphabet (IPA). The 'e' represents the short 'i' sound, the 'y' sounds like 'i', the 'ph' represents the 'f' sound, and the 's' is pronounced as 's'. The final 'is' is pronounced as 'iss'. Epiphysis refers to the rounded end of a long bone, which forms a joint with another bone.
Epiphysis is a term used in anatomy to refer to the rounded end of a long bone. In skeletal development, the epiphysis represents the part of the bone that develops from a separate center of ossification than the shaft of the bone, known as the diaphysis.
Epiphyses are mostly present in the joints of the body, where they serve several important functions. One major role of the epiphysis is to facilitate the attachment of tendons and ligaments to the bone, allowing for movement and stability. Additionally, the epiphyses contribute to the growth and development of bones, particularly during childhood and adolescence, as they contain a growth plate called the epiphyseal plate. The epiphyseal plate is responsible for longitudinal bone growth by producing new bone tissue.
Epiphyses are composed of cancellous or spongy bone, which is porous and contains bone marrow. This composition gives the epiphysis its characteristic round shape and makes it resilient but also susceptible to conditions such as fractures or diseases affecting bone health, such as osteoporosis.
Understanding the structure and role of epiphyses is essential for the study of bone development, injuries, and diseases. The presence, growth, and fusion of epiphyses play a vital part in skeletal maturation, allowing for the bone to reach its final form and function.
1. A part of a long bone developed from a center of ossification distinct from that of the shaft and separated at first from the latter by a layer of cartilage. 2. The pineal body or conarium, corpus pineale.

The word "epiphysis" is derived from the Late Latin term "epiphysis" which means "growth upon" or "something that grows upon". It comes from the Greek word "epiphysis" (επίφυσις) which has a similar meaning, referring to a growth or process of natural development. The Greek word is composed of two elements: "epi" (επί) meaning "upon" and "physis" (φύσις) meaning "growth" or "nature". Ultimately, the etymology of "epiphysis" can be traced back to the Proto-Indo-European root "*bheu" meaning "to grow" or "to be".
