Fetus=33 Adult=24
The 5 sacral and 4 coccyx bones of the fetus fuse together - that's why adults only have 24
A fetus has 33 vertebrae. The bones of the sacrum and coccyx fuse together, so adults only have 24 vertebrae.
In a fetus the rib cage is compressed laterally froming a pointed anterior rib cage surface.
the thorax becomes more rigid with age, coastal cartilages ossify
they have the same number but early fetus bones are still made of cartilage instead of ossified bone
they have the same number of vertebrae, if that is what you are asking
The fetal thoracic cage is more pliable and does not provide as much protection of organs as that of adults.
One is smaller. There are also more bones in the fetal skeleton because some bones fuse together by the time adulthood is reached.
they have bones
There are 5 lumbar vertebrae.
5
The first is the fetal skull, which is much more malleable than an adult human skull, secondly it is much, much smaller than an adults'.
Why is a transplant consisting of fetal tissue less likely to provoke an immune rejection response than tissue from an adult?
The human adult vertebral column consists of 26 bones. There are 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, and 2 that are collections of fused bones, the sacrum and the coccyx. An infant may have 32, 33, or 34 spinal bones present at birth.
The fetal vertebrae are comparing with adult from the curvatures. Some of the curvatures are not seen until after birth.
the fetal bones are much more delicate than the adult
it is weaker
The human stomach is bigger than the fetal pig's. This of course is if the human is an adult human.
The ossa coxae (containing the ililum, ishium, and pubic bones) are not fused in a fetal skeleton like in an adult human.
In fetal circulation, the placenta provides oxygen and nutrients to the fetus, so the lungs are not used for oxygen exchange - instead, a bypass called the ductus arteriosus shunts blood away from the lungs. After birth, the lungs take over oxygen exchange, the ductus arteriosus closes, and the foramen ovale between the atria closes, redirecting blood flow through the heart to support pulmonary circulation.
Fetal pigs are not as developed as an adult.
no
In a fetus, the facial area is relatively large compared to the cranium. This is because the brain grows at a slower rate compared to the facial features in the early stages of development. As the fetus grows, the cranium eventually catches up in size to accommodate the growing brain.
There are 5 lumbar vertebrae.
compare the relative lengths and paths of the uterine tubes of the fetal pig and in the human
There are many characteristics found in a fetal pig. Fetal pigs generally have all of the characteristics of an adult pig.
