Where is epiphysis of the bone?
The epiphysis lies between the growth plate (physis) and the joint at the end of the bone (Figure 8). In mice and humans, most tubular bones develop an epiphysis at both ends. Some bones, such as the phalanges and the metacarpal and metatarsal bones, ordinarily form this structure at one end only.

What is hyaline cartilage?
Hyaline cartilage, the most widely distributed form, has a pearl-gray semitranslucent matrix containing randomly oriented collagen fibrils but relatively little elastin. It is normally found on surfaces of joints and in the cartilage making up the fetal skeleton.
Is the epiphysis the growth plate?
The growth plate, also known as the epiphyseal plate is a thin layer of cartilage that lies between the epiphyses and metaphyses, and is where the growth of long bones takes place.
What is connective tissue?
Tissue that supports, protects, and gives structure to other tissues and organs in the body. Connective tissue is made up of cells, fibers, and a gel-like substance. Types of connective tissue include bone, cartilage, fat, blood, and lymphatic tissue.
