It is made up of mostly hyaline cartilage.
The skeleton of an embryo is originally made of cartilage, a flexible tissue that later undergoes ossification to become bone. During development, the cartilage is replaced by bone in a process known as endochondral ossification.
Cartilage
In an embryo, the skeleton is originally made of cartilage. This cartilage gradually mineralizes and ossifies into bone in a process called endochondral ossification.
Um, I think it is...Cartilage?
Placenta is the organ that is made from both tissue of the embryo and the mother. It forms during pregnancy for nutrient and waste exchange between the mother and fetus.
4th week
Cartilage
Well bones in an embryo aren't really there yet until the embryo becomes multi cellular and more of a child. Even when the embryo becomes more complex the bones are still just cartilage the same material that makes up your nose. Over time a bone cell called osteoblast applies both calcium and phosphate thus the bones become more dense hope i answered your question
Fetus
No, an embryo is not simply tissue. An embryo is a developing organism in the early stages of growth and differentiation. It has the potential to develop into a complex organism with individual characteristics.
Most of ab baby's bones are made up of cartilage that eventually hardens into bone
The appendicular skeleton is primarily made up of bone tissue (osseous tissue). This includes bones of the limbs (arms and legs), shoulder girdle, and pelvis. These bones provide structure, support, and attachment points for muscles.
