Olivary body

Index Olivary body

The olivary bodies or simply olives (Latin oliva and olivae, singular and plural, respectively) are a pair of prominent oval structures on either side of the medullary pyramids in the medulla, 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 between the olive and pyramid. Olivary body and anterolateral sulcus of medulla are medulla oblongata.

See Olivary body and Anterolateral sulcus of medulla

Auditory system

The auditory system is the sensory system for the sense of hearing.

See Olivary body and Auditory system

Brainstem

The brainstem (or brain stem) is the stalk-like part of the brain that connects the forebrain (the cerebrum and diencephalon) with the spinal cord.

See Olivary body and Brainstem

Facial nerve

The facial nerve, also known as the seventh cranial nerve, cranial nerve VII, or simply CN VII, is a cranial nerve that emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue.

See Olivary body and Facial nerve

Hypoglossal nerve

The hypoglossal nerve, also known as the twelfth cranial nerve, cranial nerve XII, or simply CN XII, is a cranial nerve that innervates all the extrinsic and intrinsic muscles of the tongue except for the palatoglossus, which is innervated by the vagus nerve.

See Olivary body and Hypoglossal nerve

Inferior olivary nucleus

The inferior olivary nucleus (ION) is a structure found in the medulla oblongata underneath the superior olivary nucleus. Olivary body and inferior olivary nucleus are medulla oblongata.

Medulla oblongata

The medulla oblongata or simply medulla is a long stem-like structure which makes up the lower part of the brainstem.

See Olivary body and Medulla oblongata

Medullary pyramids (brainstem)

In neuroanatomy, 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.

See Olivary body and Medullary pyramids (brainstem)

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 (pontes; from Latin pons, "bridge", from Proto-Indo-European *pónteh₁s, “path, road”, from *pent-, “path”. Cognate with Sanskrit पन्था, pánthā-) is part of the brainstem that in humans and other mammals, lies inferior to the midbrain, superior to the medulla oblongata and anterior to the cerebellum.

See Olivary body and Pons

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). Olivary body and posterolateral sulcus of medulla oblongata are medulla oblongata.

See Olivary body and Posterolateral sulcus of medulla oblongata

Sound

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

See Olivary body and Sound

Spinocerebellar tract

The spinocerebellar tract is a nerve tract originating in the spinal cord and terminating in the same side (ipsilateral) of the cerebellum.

See Olivary body and Spinocerebellar tract

Superior olivary complex

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

See Olivary body and Superior olivary complex

Vestibulocochlear nerve

The vestibulocochlear nerve or auditory vestibular nerve, also known as the eighth cranial nerve, cranial nerve VIII, or simply CN VIII, is a cranial nerve that transmits sound and equilibrium (balance) information from the inner ear to the brain.
