The early development of theskeletal system begins in the third week after conception with the formation of the notochord (a rod-like structure along the back of the embryo that later becomes the spine, spinal cord, and brain), followed in the fourth week by the first signs of arms and legs. Between the fifth and eighth weeks, the limbs (first the arms, hands, and fingers, followed by the legs, feet, and toes) begin to extend and take on a definite shape.By the end of the fifth week, the embryo has doubled in size and has grown a tail-like structure By the seventh week the embryo is about 2 cm (1 in) long and facial features are visibleAt this stage, the 206 bones of the human body are all set down, in surprisingly adult form. hope this info helps xx
What else can I help you with?
What type of tissue is replaced in the embryo during endochondral ossification?
During endochondral ossification, the hyaline cartilage model in the embryo is gradually replaced by bone tissue. Osteoblasts deposit bone matrix around the cartilage model, which is then mineralized and eventually becomes mature bone tissue.
What is the main bone in the adult leg?
Tibia APEX
When a human embryo is developing the embryo produces a special type of hemoglobin not found in infant child or adult blood. Why does an embryo produce a different type of hemoglobin from an infant ch?
An embryo produces a specific type of hemoglobin called fetal hemoglobin (HbF) that has a higher affinity for oxygen than the adult hemoglobin. This allows the developing embryo to efficiently obtain oxygen from the maternal blood supply through the placenta. Once born, the infant starts producing adult hemoglobin to adapt to breathing air in the postnatal environment.
What is skeleton originally made of in an embryo?
In an embryo, the skeleton is originally made of cartilage. This cartilage gradually mineralizes and ossifies into bone in a process called endochondral ossification.
What is the skeleton of an embryo mainly composed of?
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
The developmant of the bone from the embryo to maturity?
the development of the bone from the embryo to maturity
Are more stem cells found in an embryo or an adult?
There are more cells found in an embryo than an adult.
When does bone develop in the embryo?
At around 15 weeks of pregnancy.
What is the location of compact bone in an adult's bone?
Diaphysis
How do embryo help identify a common ancestor of different organisms?

Where does Red Blood cells produce in body and Embryo?
for our body, it is in the bone marrow
What type of tissue is replaced in the embryo during endochondral ossification?
During endochondral ossification, the hyaline cartilage model in the embryo is gradually replaced by bone tissue. Osteoblasts deposit bone matrix around the cartilage model, which is then mineralized and eventually becomes mature bone tissue.
What are the differences between embryo and adult stem cells?
Adult stem cells are harvested from newborn's cord blood or human bone marrow while embryo stem cells come from the inner cell mass of a human embryo. No fetus is killed to use the stem cells, but the embryo cannot function and must be destroyed without a inner cell mass.
What is the main bone in the adult leg?
Tibia APEX
Bone does not articulate with other bone?
The hyoid bone is the only bone in the adult body that doesn't articulate with another bone.
What is the smallest bone in the adult body?
stapes bone in the middle ear
What is the largest bone in the adult human body?
The femur ("thigh bone").
