The epiphyseal plate is an area at the long end of the bone that contains growing bone. As people develop, the bone grows longer as a result of activity inside this area. These plates permit growth after birth, allowing the long bones of the body to extend and a person to grow as he or she reaches maturity. Once growth is completed and the person reaches full maturity and stature, the new bone slowly hardens and the plate turns into the epiphyseal line.
The plates fuse over at a stable and predictable rate, so someone with experience can examine a bone and make an estimate of its age. After about age 25, when the epiphyseal lines are fully formed, it is much harder to figure the age.
What else can I help you with?
What fossils are useful in determining the relative age of rocks?
Index fossils
Why would uranium-238 not be useful in determining the age of a spear that is thought to be 5000 years old?
Uranium dating is useful for long periods of time - e.g. 109 years. For fossils is recommended the method with 12C.
What is bone remodeling and how can it be used to determine age?
Bone remodeling is a lifelong process where old bone is removed and new bone is formed. By studying the pattern of bone remodeling in skeletal remains, such as the amount of mineralization and presence of growth plates, forensic anthropologists can estimate the age of an individual at the time of death. Changes in bone density and structure can provide valuable clues for determining age.
What are the differences between oceanic crust and continental crust in age terms?
Overall their materials are of the same age, but the continental plates simply break or collide whereas the ocean-floor plates are in constant cycles of construction and destruction.
Why are index useful to geologists?
they tell the absoute age of rcoks which they occur
What are epiphyseal fusions and what can they tell a forensic anthropologist?
Epiphyseal fusions are the process where the growth plates in bones close as a person reaches skeletal maturity. Forensic anthropologists can use the degree of epiphyseal fusion to estimate the age of individuals at the time of death, which helps in identifying the individual.
How rocks layer useful in determining the age of the earth?
they are useful by showing where the fossil is buried then on that certain layer, it will be studied to know the age.
What fossils are useful in determining the relative age of rocks?
Index fossils
What property of radioactive elements make useful for determining absolute age?
Igneous rock. If you are in FIS you know me. O.K.
When does Epiphyseal Plate close?
Epiphyseal plates close after puberty. This because your body begins to produce testosterone, which is in turn converted into estrogen, which is responsible for the closing of the growth plate or Epiphyseal Plate. So it differs from person to person, if you have gone through puberty then your growth plates are developed.
Can you see an epiphyseal plate on a open dried femur bone?
Not if it is a femur from a skeletally mature individual. The epiphyseal plate of the femur closes at around age 17 or 18. After this age, you would not see the epiphyseal plate, but you should be able to see the physis (or physeal) scar. This is the point at which the epiphysis and metaphysis have fused.
How long does longitudinal bone growth occur?
Longitudinal bone growth occurs until the growth plates, also known as epiphyseal plates, close. This typically happens around the age of 18 in girls and 20 in boys. After the growth plates close, bones stop growing in length.
What property of radioactive elements make them useful for determining absolute age?
The property of radioactive decay is what makes radioactive elements useful for determining absolute age. By measuring the amount of parent and daughter isotopes in a sample, scientists can calculate the age of the material based on the known half-life of the radioactive element.
How do you tell how old a box turttle is?
The only way to really be sure of a box turtle's age is to be present at the hatching. Determining age by the hexagonal lines on the plates of the shell (scutes) is not reliable.
Are foot bones the slowest growing bones in the body?
Yes, foot bones are among the slowest growing bones in the body. The growth plates in the feet, known as epiphyseal plates, close around the late teens to early twenties, which is one reason why foot size tends to stop increasing significantly after that age.
A fault can be useful in determining which group of rocks?
A fault can be useful in determining the relative ages of different rock layers by showing which layers have been displaced or shifted due to tectonic forces. This can help geologists establish the sequence of events in an area's geological history.
Measurements of half-life make radioactive isotopes useful for?
They're useful for x-rays or looking at metals,or determining the age of rocks/fossils. (Hope it helped!😁)
