The correct order of major developmental theorists from oldest to most recent is Sigmund Freud, Erik Erikson, Jean Piaget, Lev Vygotsky, and Urie Bronfenbrenner.
Inside bones. The bone marrow is the tissue in the centre of bones and makes most of the body´s white blood cells. The thigh and leg bones are the biggest so they ususally make the most white cells.
The placenta is the part of the amniotic egg that supplies food to the developing animal. The yolk provides it with food, and the albumin supplies water and nutrients.The Yolk. Yolk is a sac that is attached to the embryo that supplies food.
The fossils displayed in mueseums are usually plaster to prevent the originals from being damaged. The real ones are kept in a lab, most are at the American Mueseum of Natural History. There, they can be studied.
Hyaline cartilage is the forerunner of long bones in the embryo.
In the embryo, most of the developing bones are initially formed from a flexible tissue called cartilage, specifically hyaline cartilage. This cartilage serves as a template that gradually ossifies, or hardens, into bone through a process called endochondral ossification. Some bones, such as those in the skull and clavicles, develop directly from mesenchymal tissue through intramembranous ossification. Overall, the transition from cartilage to bone is crucial for the proper formation and growth of the skeletal system.
Most of ab baby's bones are made up of cartilage that eventually hardens into bone
Most sources claim that the African rhinoceros has 194 bones. The horn on the head is not made of bone. It is made of the same material as fingernails.
In the marrow of your bones.
The middle germ layer is called mesoderm. It gives rise to structures like muscles, bones, and the circulatory system in the developing embryo.
Are you talking about shark skeletons? Yes, they are bones. However, they are made of a different, softer material, than most bones from other animals - cartilage.
Most fish have bones. Sharks and rays do not have bones but they do have bone-like structures that are made from cartilage.
The adult human body has 206 bones. An infant may have from 300-350 bones at birth. Some of these fuse together as the infant grows. When some bones fuse and become one bone (most obvious examples are in the skull, sacrum and hip bones) the number of overall bones drops to the 206 bones that most adults have.

most of your bones are created in the.....
Most probably no. Embryo is the starting point of germination as all hormones concerned are placed there.
