The olive consists of two parts: The inferior olivary nucleus (or 'complex'), which is a part of the olivo-cerebellar system and is mainly involved in cerebellar motor-learning and function. The superior olivary nucleus, considered part of the pons and part of the auditory system, aiding the perception of sound.
The inferior olivary nucleus (ION) is a structure found in the medulla oblongata underneath the superior olivary nucleus. [1] In vertebrates, the ION is known to coordinate signals from the spinal cord to the cerebellum to regulate motor coordination and learning. [2]
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 ...
The axons end by synapsing on third-order neurons in the inferior olivary nuclei in the medulla oblongata. The axons of the third-order neurons cross the midline and enter the cerebellum through the inferior cerebellar peduncle. [2] The spino-olivary tract conveys information to the cerebellum from cutaneous and proprioceptive organs.
The superior olivary complex is generally located in the pons, but in humans extends from the rostral medulla to the mid-pons [1] and receives projections predominantly from the anteroventral cochlear nucleus (AVCN) via the trapezoid body, although the posteroventral nucleus projects to the SOC via the intermediate acoustic stria. The SOC is ...
The medulla oblongata or simply medulla is a long stem-like structure which makes up the lower part of the brainstem. [1] It is anterior and partially inferior to the cerebellum . It is a cone-shaped neuronal mass responsible for autonomic (involuntary) functions, ranging from vomiting to sneezing . [ 2 ]
Obesity raises a person’s risk of developing type 2 diabetes. Researchers from Virginia Tech have found a natural compound in olives and olive oil that might help improve blood sugar control and ...
Also at the side of each pyramid there is a pronounced bulge known as an olive. Fibers of the posterior column, which transmit sensory and proprioceptive information, are located behind the pyramids on the medulla oblongata. The medullary pyramids contain motor fibers that are known as the corticobulbar and corticospinal tracts. The ...
