ANATOMY

Detailed explanation-1: -epiphysis, expanded end of the long bones in animals, which ossifies separately from the bone shaft but becomes fixed to the shaft when full growth is attained. The epiphysis is made of spongy cancellous bone covered by a thin layer of compact bone .

Detailed explanation-2: -A long bone has a shaft, or the central part of the bone, known as diaphysis and two ends, known as epiphysis.

Detailed explanation-3: -the end of a long bone, initially separated from the shaft (diaphysis) by a section of cartilage that eventually ossifies so that the two portions fuse together. Also called: epiphysis cerebri (ˈsɛrɪˌbraɪ) the technical name for pineal gland.

Detailed explanation-4: -A hollow medullary cavity filled with yellow marrow runs the length of the diaphysis of a long bone. The walls of the diaphysis are compact bone. The epiphyses, which are wider sections at each end of a long bone, are filled with spongy bone and red marrow.
