B) semicircular canal and cupula
C) utricle and semicircular canal
D) saccule and cupula
E) utricle and cupula
Gravitational Equilibrium
A state in which the gravitational forces within a star are perfectly balanced by the outward push of pressure from fusion reactions in the star's core.
Utricle
The utricle is a part of the inner ear involved in detecting linear movements and the position of the head in relation to gravity, aiding in balance.
Saccule
Saclike cavity in the vestibule of the vertebrate inner ear; contains sensory receptors for gravitational equilibrium.
- Gain insight into the configuration and placement of sensory receptors responsible for the senses of smell, touch, taste, hearing, and vision.
- Elucidate on the physiological mechanisms underlying sensory perception.

Final Answer :
A
Explanation :
Gravitational equilibrium is associated with the utricle and saccule, which are two structures located in the vestibule of the inner ear. They contain sensory receptors that detect changes in the position of the head relative to gravity. The other structures listed (semicircular canals and cupula) are associated with detecting rotational movement of the head.
