Answer:
The correct answer is A. Intramembranous ossification forms the bones of the roof of the skull.
Explanation:
Intramembranous ossification is one of two types of bone formation and is responsible for the development of flat or laminated bones, especially those in the skull.
This type of ossification occurs within the connective tissue membranes, the so-called primary ossification center. Mesenchymal cells differentiate into osteoblasts. These, in turn, synthesize osteoids (newly synthesized bone matrix), which mineralize, giving rise to osteocytes. Several of these ossification centers happen simultaneously within a connective tissue membrane. Thus, the formed bone beams give a spongy aspect to the bone, allowing the penetration of blood vessels in these formed cavities, originating the bone marrow. The part of the connective membrane that does not ossify becomes the endosteum and periosteum, inwards and outwards.
While bone end-to-end ossification occurs from center to extremity, intramembranous bone develops differently from ossification nuclei, which expand and join over time. The skull, for example, ossifies in this way. For this reason, care should be taken when striking the head of newborns so as not to affect the brain that is not yet fully protected.
Diarrheal disease, Chronic obstructive pulmonary disease, Respiratory infections are close link with environment risk factors.
So, the correct option is D.
Pollution, radiation, noise, land use practices, and climate change are a few of the environmental risks to health. The body of evidence relating the environment to human health is constantly expanding and being updated, making environmental health a growing field of study. The health and well-being of people can be hampered by a number of specific environmental problems. Chemical pollution, air pollution, climate change, pathogenic microbes, a lack of access to healthcare, inadequate infrastructure, and poor water quality are some of these problems.
Environmental risks from biology, chemistry, and physics On the basis of the characteristics of their causes, environmental hazards can also be divided into three interrelated categories (biological, chemical, and physical).
