ANATOMY

Detailed explanation-1: -Sacculus: It is a part of the semicircular canals of the inner ear. It contains sensory cells called the macula which help in the static balance of the body when it is in a stationary position.

Detailed explanation-2: -This circuitry starts with the vestibular system: a sensory system in the inner ear that relies on hair cells to detect movements, and to provide our sense of balance and spatial awareness. The vestibular system contains five organs that are sensitive to different types of movement.

Detailed explanation-3: -The vestibule sits between and connects the cochlea and semicircular canals and helps to maintain equilibrium (Figs. 22.6 and 22.9). Within the vestibule are two regions lined by the membranous labyrinth; the utricle, which is closer to the semicircular canals, and the saccule, which is closer to the cochlea.
