Skeletal System ? UnExplanation / Answer
1. If there is a fracture in the orbit then a total of seven bones that surround the orbit of the eye could be potentially involved are Frontal Bone and Sphenoid forming the Superior Margin, Ethmoid, Lacrimal, Sphenoid and Maxilla of the Medial margin and lastly Maxillary bone, Palantine and Zygomatic bone of the Inferior margin.
Orbital fractures are often difficult to fixate surgically with screws and plates because if there is some kind of complication in placing the screws and plates then this will lead to change in the globe position and may even lead to loss of vision.
2. The nose consists of different types of bones, tissues, cartilage. The two main parts of the nose can be divided into External Nasal Skeleton and Internal Nasal Septum. The bones that could be fractured in External Nasal Skeleton are Nasal Bone and Maxilla whereas the bones that could be fractured in the Internal Nasal Septum are Ethmoid, Vomer and Palantine bones apart from the Nasal and Maxilla.
3. The bones of the fetal skull are not yet fused and give rise to soft spots or fontanelles. These soft spots or fontanelles are critical for molding of the head of the fetus to the birth canal during labor. This helps in the delivery of the child during labor.
4. The most important difference between the male and female anatomy is the difference in the anatomy of the pelvis. The female pelvis is wider than that of the male in order to adapt the body of the female for gestation. The pelvic ring is more circular in nature in case of women so that the new born can pass through easily.
