How does the fetal skeleton sternum compare to the adult skeleton sternum?
it is weaker
What is the fetal skeleton mainly composed of?
Cartilage
How many fontanels in a fetal skeleton?
4 or more
Does Fibrocartilage makes up the fetal skeleton?
No. It is hyaline cartilage
What are two characteristics of the fetal skeleton skull that differ from the adult skeleton?
Two characteristics of the fetal skeleton skull that differ from the adult skeleton are the presence of fontanelles (soft spots) in the fetal skull that allow for flexibility during childbirth, and the incomplete fusion of cranial bones in the fetus compared to the fully fused bones in adults.
How does the ossa coxae compare in the fetal skeleton and adult skeleton?
In the fetal skeleton, the ossa coxae (hip bones) are not fully fused, and they consist of three separate bones: ilium, ischium, and pubis. In the adult skeleton, these three bones have fused together to form a single hip bone. Additionally, the acetabulum, the socket where the femur connects to the hip bone, is not fully developed in the fetal skeleton but is complete in the adult skeleton.
Is the skeleton cartilaginous or bony during fetal development?
The skeleton is originally cartilaginous during fetal development. Over time, the cartilage is replaced by bone in a process called endochondral ossification, where bone tissue gradually forms and replaces the cartilage framework.
How does the ossa coxae compare in a fetal skeletal and adult skeletal?
The ossa coxae (containing the ililum, ishium, and pubic bones) are not fused in a fetal skeleton like in an adult human.
What overall change in the skeleton occurs during fetal development?
During fetal development, the skeleton undergoes significant changes, primarily transitioning from a cartilage-based framework to a bony structure. Initially, the fetal skeleton is composed mostly of hyaline cartilage, which serves as a model for bone formation. As development progresses, ossification begins, where bone tissue replaces cartilage, resulting in a more rigid and supportive structure. This transformation is crucial for the developing fetus, allowing for growth and preparation for birth.
Inside its skeleton is what kind of phrase?
"Inside its skeleton" is a prepositional phrase, used to show the location of something in relation to the skeleton.
When axial skeleton is axis of the body is it distal or proximal?
The axial skeleton, which includes the skull, vertebral column, and rib cage, serves as the central axis of the body. It is considered proximal in relation to the appendicular skeleton (the limbs), as it is closer to the center or midline of the body. Therefore, the axial skeleton is proximal, while the appendicular skeleton is more distal.
Is not a function if the skeleton?
In mathematics, a relation is not considered a function if it assigns multiple outputs to a single input. In the context of a "skeleton," it may refer to a graph or set of points that do not adhere to the definition of a function. For instance, if a vertical line intersects the graph of a relation at more than one point, it confirms that the relation is not a function. Thus, a function must pass the vertical line test to be valid.
