A gymnast is able to balance his body upside down even in total darkness because of:
Correct answer: D. Vestibular apparatus
- A. Tectorial membrane
- B. Organ of corti
- C. Cochlea
- D. Vestibular apparatus
Explanation
The vestibular apparatus is present in the ear. It forms the labyrinth of the inner ear in association with the cochlea. This apparatus is responsible for the balance and sense of orientation of the body in the air. It consists of 3 semi-circular canals, the base of which consists of the ampulla, and the otolith organ, which consists of the utricle and saccule, which have a projecting ridge called the macula. When the body is oriented in a different form in the darkness or absence of light, the apparatus helps to determine the orientation. Thus, the correct answer is option D.

About Coordination and Control
Coordination depends on receptors, neurons, synapses and nerve impulses, with reflex actions traced through the reflex arc and the roles of major brain regions. Chemical coordination covers endocrine glands and hormones, including how hormones regulate growth, metabolism, reproduction and internal balance, unlike rapid nervous control.
