Question

Process in the balancing of body is given below. Arrange them in sequential order.

A) Impulses are generated.

B) The muscle activities are coordinated.

C) Equilibrium of the body is maintained.

D) Stimulate the receptors present in the vestibular apparatus.

E)The impulses are transmitted to the cerebellum.

F) Movement of the head bring about the movement of the endolymph present inside the vestibule and semicircular canal.​

Answer 1

F)→D)→A)→E)→B)→C) is the correct sequential order

Explanation:

• Equilibrium is sensed by mechanoreceptors present in semicircular canal and vestibular apparatus . these two organ are present in inner ear and have consist of bony labyrinth and membranous labyrinth .
• A liquid is present within the membranous labyrinth is called endolymph
• hair cell tips i.e. mechanoreceptor are immersed in endolymph
• Movement of head causes movement of endolymph. movement of endolymph stimulate receptor  in vestibular apparatus  as it concerned with movement of head.
• As a result of stimulation an impulse or action potential is generated which is transmitted to cerebellum as this part of the head control balance of the body.
• cerebellum then control muscular activities and equilibrium of body is maintained
