The epiphyseal plate is a cartilaginous structure at the end of long bones that is involved in bone growth during childhood and adolescence. Once growth stops, this cartilage is replaced by bone, forming the epiphyseal line. The epiphyseal plate allows bone growth, while the epiphyseal line indicates that growth has ceased.

What is the region of longitudinal growth in a child?
The region of longitudinal growth in a child is the epiphyseal plate, commonly known as the growth plate. This area is located at the ends of long bones and is responsible for bone lengthening during childhood and adolescence by the process of endochondral ossification. Once growth is complete, the growth plate closes and becomes a bony structure known as the epiphyseal line.
What temperature difference should be expected between the indoor line and the permanent suction -line ports on the reversing valve during the cooling cycle?
During the cooling cycle, a temperature difference of around 18-20°F is expected between the indoor suction line and the permanent suction line ports on the reversing valve. This temperature difference indicates proper operation of the system.
What is the distance between two points on a line?
The distance between two points on a line is the absolute value of the difference between their coordinates. This can be calculated using the distance formula: |x2 - x1|, where x1 and x2 are the coordinates of the two points.
The difference between the final position and the initial position if motion is in a straight line?
The difference between the final position and the initial position in straight-line motion is the displacement. It is a vector quantity that represents the overall change in position, including direction. It is calculated by subtracting the initial position from the final position.
What is difference between a line and a ray?
A line extends infinitely in both directions, while a ray has a starting point and extends infinitely in one direction. A line has no endpoints, while a ray has one endpoint.
What structure would be present instead of a epiphyseal line?
epiphyseal plate
How is bone marrow articular cartilage the epiphyseal line and epiphyseal plate related?
Bone marrow, articular cartilage, epiphyseal line, and epiphyseal plate are all components of the skeletal system. Articular cartilage covers the ends of long bones that form joints. The epiphyseal line represents a remnant of the epiphyseal plate, which is a cartilaginous plate in long bones where growth occurs. Bone marrow is the soft tissue found inside bones that produces blood cells and stores fat.
This is a layer of hyaline cartilage that allows the diaphysis to grow in length?
The layer you are referring to is the epiphyseal plate, also known as the growth plate. It is found at the ends of long bones in children and adolescents, allowing the bone to lengthen as the cartilage cells multiply and are replaced by new bone tissue. Once growth is complete, the epiphyseal plate ossifies and becomes the epiphyseal line.
It is epiphysis line growth plate remnant?
The epiphyseal line is a remnant of the epiphyseal growth plate, which is a cartilaginous structure present in growing bones. Once bone growth is complete, the growth plate calcifies and transforms into the epiphyseal line, indicating the end of longitudinal bone growth.
Can the epiphyseal plate be seen in both the external and cutaway views of an adult long bone?
No, the epiphyseal plate is only visible in the cutaway view of a long bone in an adult. In the external view of an adult long bone, the epiphyseal plate has ossified and is no longer visible since it has become the epiphyseal line.
The longitudinal growth of long bones ceases when?
The epiphyseal plate ossifies and becomes the epiphyseal line in long bones. This begins at puberty.
What is the growth plate also known as?
The epiphyseal plate is an area at the long end of the bone which contains growing bone. It is located between the epiphysis at the end of the bone and the diaphysis of another bone. This is only found in children and adolescents as it turns into the epiphyseal line in adults.
Where do long bones lengthen?
Long bones such as the femur length along the epiphyseal plate that turns into the epiphyseal line in adults when their growth is complete.
Epiphyseal plate being replaced by epiphyseal line is an indication that bone growth?
The replacement of the epiphyseal plate by the epiphyseal line indicates that the individual has reached skeletal maturity, and bone growth has stopped in length. Further bone growth can still occur in width and density through a process known as appositional growth.
What is another name for the epiphyseal line on the humerus?
The epiphyseal line on the humerus is also known as the line of fusion or the metaphyseal scar. This line represents the site where the growth plate has fused and bone growth has ceased.
What is the structure of an epiphyseal plate?
The epiphyseal plate is a layer of hyaline cartilage found at the ends of long bones in children and adolescents. It consists of different zones: resting zone, proliferative zone, hypertrophic zone, and ossification zone. These zones allow for longitudinal bone growth by transforming cartilage into bone tissue.
In the epiphyseal plate cartilage grows?
the epiphyseal plate is also called the growth plate. it is the area of cartilage between the diaphysis (the long shaft of the bone) and the epiphysis (the end of a bone). the cartilage will expand and go through a process called ossification and turn into bone. when a person is done growing the epiphyseal plate will turn into an epiphyseal line.
