Explanation / Answer

c, nasal bone is an exception because paranasal bones are airfilled spaces found on the bones of the skull and faces. It mainly found on the bones around the nose, which includes frontal, sphenoid, maxillary and ethmoid bones b is the wrong statement because cervical region of vertebral column is mainly iordotic curve in nature in which it is convex anteriorly and concave posteriorly b is the right answer because mainly hard palate is made up of palatine process of two maxillary bones anteriorlly and horizontal plates of two palatine bones, it mainly separates nasal cavity from oral cavity c is the exception because axial skeleton includes the bones of skull, thorax and vertebral column which have rib, hyoid, ethmoid and sternum whereas appendicular skeleton includes the bones of shoulder, arm, hand, pelvis,leg and foot which contain clavicle a is the right statement because all the ribs articulate posteriorly with the thoracic vertebrae and anteriorly with the sternum either directly or indirectly anterior fontanel is the largest fontanel of the infants skull. Fontanel is the space between the bones of infants skull where the sutures meet which is covered with a tough membrane, and is of two types anterior fontanelle situated between two frontal and two parietal bones meet and posterior fontanelle where two parietal bones and occipital bones meet. So largest fontanelle is situated between frontal and parietal bones so a is the right answer b is the right answer because immovable joints are tightly joined and is separated by a thin layer of fibrous connective tissue which is also called synathrosis joint, skull bones are joined by athin immovable joined called sutures except mandibles c is the right answer, maxillary bones articulat with all other facial bones except manidbles and forms floor and medial portion of the rim of the orbit, walls of nasal cavity and anterior roof of mouth
