Which nerve innervates the right lateral rectus muscle?
For example, while reading a book, when the head is turned leftward, the horizontal semicircular canals send signals to vestibular nuclei. This vestibular nucleus excites the contralateral abducens nucleus which innervates the right lateral rectus muscle through the sixth cranial nerve. The contraction of the right lateral muscle occurs. It also sends a signal to the ipsilateral oculomotor nucleus, which innervates the medial rectus muscle through the third cranial nerve. The oculomotor nucleus excites the left medial rectus. In this way, the resulting eye movement in the opposite direction of the head movement stabilizes the gaze on the book.

What might it look like if the vestibular system isn’t working well?
When the vestibular system doesn’t process the information it receives very well, there are three typical responses. Some children and adults are sensitive to vestibular input, which means their brains respond to only a small amount of movement. Other children and adults are slower to respond to the input, which means they need more movement to understand the information their vestibular sense receives. These children and adults could either respond by seeking out more movement or by just being slow to respond and a bit sluggish. There are also children or adults who might display a combination of the three responses.

Maintenance of Dynamic Equilibrium
- The vestibular system detects the angular acceleration and maintains the dynamic equilibrium through three semicircular canals. When the head is rotated in any direction, the endolymph stays stationary because of its inertia while the semicircular ducts move. In this way, the relative motion of the fluid is in the opposite direction of the head movement. The fluid deflects the jellylike stru…
Maintenance of Static Equilibrium
- The vestibular system detects the linear acceleration and maintains the static equilibrium through otolithic organs: the utricle and the saccule. The hair cells present in the maculae of the utricle and the saccule are all oriented in different directions. This causes stimulation of different hair cells with the different positions of the head. The stimulation of the hair cells causes the brain t…
Eye Stabilization
- When a person moves his head in different directions or changes his body movements rapidly, the vestibulo-ocular reflexes (VOR) helps the person to stabilize the direction of their eyes. It produces reflex eye movements that are equal and opposite in direction to the movement of the head. VOR is very fast and accurate and it allows people to stabilize their gaze while doing physical activitie…
Vestibulospinal Pathways
- The vestibulospinal tract is a descending neural tract in the CNS which relays the information from vestibular nuclei to motor neurons. It plays an important role in maintaining upright posture and balance, stabilizing the gaze, and realization of orientation and motion. The tract consists of two sub pathways. 1. Medial vestibulospinal tract The medial vestibulospinal tract originates in t…
