Olivary body

Index Olivary body

In anatomy, the olivary bodies or simply olives (Latin oliva and olivae, singular and plural, respectively) are a pair of prominent oval structures in the medulla oblongata, the lower portion of the brainstem. [1]

Anterolateral sulcus of medulla

The anterolateral sulcus (or ventrolateral sulcus) is a sulcus on the side of the medulla oblongata.

Hypoglossal nerve

The hypoglossal nerve is the twelfth cranial nerve, and innervates all the extrinsic and intrinsic muscles of the tongue, except for the palatoglossus which is innervated by the vagus nerve.

Inferior olivary nucleus

The inferior olivary nucleus (ION), is an evolutionarily conserved structure found in the medulla oblongata underneath the superior olivary nucleus.

Medulla oblongata

The medulla oblongata (or medulla) is located in the brainstem, anterior and partially inferior to the cerebellum.

Medullary pyramids (brainstem)

The medullary pyramids are paired white matter structures of the brainstem's medulla oblongata that contain motor fibers of the corticospinal and corticobulbar tracts – known together as the pyramidal tracts.

Olivocerebellar tract

The olivocerebellar tract, also known as olivocerebellar fibers, are neural fibers which originate at the olivary nucleus and pass out through the hilum and decussate with those from the opposite olive in the raphe nucleus, then as internal arcuate fibers they pass partly through and partly around the opposite olive and enter the inferior peduncle to be distributed to the cerebellar hemisphere of the opposite side from which they arise.

Pons

The pons (Latin for "bridge") is part of the brainstem, and in humans and other bipeds lies inferior to the midbrain, superior to the medulla oblongata and anterior to the cerebellum.

Posterolateral sulcus of medulla oblongata

The accessory, vagus, and glossopharyngeal nerves correspond with the posterior nerve roots, and are attached to the bottom of a sulcus named the posterolateral sulcus (or dorsolateral sulcus).

Sound

In physics, sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as a gas, liquid or solid.

Superior olivary complex

The superior olivary complex (or SOC or superior olive) is a collection of brainstem nuclei that functions in multiple aspects of hearing and is an important component of the ascending and descending auditory pathways of the auditory system.

Ventral spinocerebellar tract

The ventral spinocerebellar tract conveys proprioceptive information from the body to the cerebellum.

Vestibulocochlear nerve

The vestibulocochlear nerve (auditory vestibular nerve), known as the eighth cranial nerve, transmits sound and equilibrium (balance) information from the inner ear to the brain.
