Skull Bones and Ear Ossicles — NEET Biology
📚 Practice ConceptCranial bones are 8 in number. They form the hard protective outer covering, cranium for the brain. The facial region is made up of 14 skeletal elements which form the front part of the skull. A single U-shaped bone called hyoid is present at the base of the buccal cavity. Each middle ear contains three tiny bones – Malleus, Incus and Stapes, collectively called Ear Ossicles. The skull region articulates with the superior region of the
Match the following skeletal parts/regions with their correct characteristics or numbers: Column I: Skeletal Part / Region A. Cranial bones B. Thoracic vertebrae C. Floating ribs D. Cervical vertebrae E. True ribs Column II: Characteristic / Number i. Dorsally connected to thoracic vertebrae, ventrally to sternum with hyaline cartilage ii. 8 in number, form the protective covering for the brain iii. 12 units, providing dorsal attachment for ribs iv. 11th and 12th pairs, not connected ventrally v. 7 in number, found in the neck region Which of the following options correctly matches Column I with Column II?
View solution & NCERT explanation
Correct answer: A — A–ii, B–iii, C–iv, D–v, E–i
The anchor concept is the identification and enumeration of bones, particularly within the axial skeleton, and their specific features. A. Cranial bones: The NCERT states, 'Cranial bones are 8 in number. They form the hard protective outer covering, cranium for the brain.' So, A matches with ii. B. Thoracic vertebrae: The NCERT mentions 'thoracic (12)' vertebrae and that ribs are connected dorsally to them. So, B matches with iii ('12 units, providing dorsal attachment for ribs'). C. Floating ribs: The NCERT states, 'Last 2 pairs (11th and 12th) of ribs are not connected ventrally and are therefore, called floating ribs.' So, C matches with iv. D. Cervical vertebrae: The NCERT mentions 'cervical (7)' vertebrae and their position as 'starting from the skull' (neck region). So, D matches with v. E. True ribs: The NCERT states, 'First seven pairs of ribs are called true ribs. Dorsally, they are attached to the thoracic vertebrae and ventrally connected to the sternum with the help of hyaline cartilage.' So, E matches with i. Therefore, the correct matches are: A–ii, B–iii, C–iv, D–v, E–i. The final answer is A. The concept tested is the detailed knowledge of axial skeleton components, their numbers, and specific anatomical characteristics as described in NCERT.
