The coordination of the arms, legs, and any motions involving hand-eye coordination depends on the arbour vitae, which is located in the centre of the cerebellum. White matter, which carries information throughout the brain, is what makes up the arbour vitae.
The pink-tinted myelinated axons that carry nerve impulses make up arbour vitae. The pink hue of the arbour vitae is a result of protein and lipid substances found in the myelin sheaths that protect the axons.
Damage to the myelin sheaths can lead to multiple sclerosis or other diseases being contracted by a person. Cerebellar haemorrhage brought on by tumours and infections brought on by microorganisms that cause ataxia are other problems that might affect arbour vitae.
The emboliform-globose, dentate, and deep cerebellar nuclei are all found inside the arbour vitae, as well as the fastigial and fastigial nuclei. The efferent projections in the cerebellum are connected to these structures.
The cerebral cortex has irregular convolutions, whereas the cerebellum, which is located below the rest of the brain, has parallel groves that give it the appearance of being a separate entity. A continuous layer of tissue that is firmly folded like an accordion makes up the cerebellum.
Due to its resemblance to a tree, the word arbour vitae, which means “tree of life,” is Latin. French explorers brought the Aborvitae tree species to Europe, where it became well-known for its ability to treat scurvy by preparing tea from its leaves and bark. It was given that name in 1558 as a result of its medicinal qualities.
