Question

Which of the following is INCORRECT with respect to bone and its associated part?

• A. Atlas vertebra - Odontoid process
• B. Pectoral girdle - Acromion process
• C. Humerus - Trochlea
• D. Ulna - Styloid process

Answer 1

Answer: (A)

First cervical vertebrae is Atlas and Second cervical vertebrae is Axis. Both are atypical which means have special characteristic feature. Atlas lacks a body and a spinous process. Axis has dens or odontoid process.
Pectoral girdle consists of Scapula and Clavicle. Scapula or shoulder blade has acromian process which attches with clavicle. Humerus is the bone of arm and has troclear process. Radius and Ulna are bones of forearm. Ulna has styloid process at the distal end of forearm.
