The lacrimal bone is the smallest and most fragile bone of the face; roughly the size of the little fingernail. It is situated at the front part of the medial wall of the orbit.It has two surfaces and four borders.Several bony landmarks of the lacrimal bone function in the process of lacrimation or crying.n early lobe-finned fishes and ancestral tetrapods, the lacrimal bone is a relatively large and robust bone, running from the orbit to the nostrils. It forms part of the side of the face, between the nasal bones and the maxilla.
Medical Definition of spinocerebellar. : of or relating to the spinal cord and cerebellum spinocerebellar degeneration.
The ventral spinocerebellar tract is located immediately ventral to the dorsal spinocerebellar tract in the lateral funiculus. It arises mainly from neurons in the contralateral side of the lower thoracic, lumbar and more caudal segments of the spinal cord.xons of the sensory neurons in the dorsal root ganglia enter the spinal cord white matter and ascend ipsilaterally in the dorsal column to terminate on the gracile and cuneate nuclei. These constitute the direct dorsal column pathways (the gracile and cuneate fasciculi).
