What is the function of flocculonodular lobe?
2.1 The Flocculonodular Lobe. The flocculonodular lobe receives input from the primary vestibular afferents and projects back to the vestibular nuclei. This portion of the cerebellum governs eye movements and body equilibrium during stance and gait.
What is Flocculonodular?
The flocculonodular lobe is a lobe of the cerebellum consisting of the nodule and the flocculus. The two flocculi are connected to the midline structure called the nodulus by thin pedicles. This lobe is also involved in the maintenance of balance equilibrium and muscle tone.
What makes up the flocculonodular lobe?
The flocculonodular lobe (vestibulocerebellum) is a lobe of the cerebellum consisting of the nodule and the flocculus. The two flocculi are connected to the midline structure called the nodulus by thin pedicles.
What is the Floccular lobe?
Anatomical terms of neuroanatomy The flocculus (Latin: tuft of wool, diminutive) is a small lobe of the cerebellum at the posterior border of the middle cerebellar peduncle anterior to the biventer lobule. Like other parts of the cerebellum, the flocculus is involved in motor control.
Where is the cerebellar vermis?
cerebellum
The cerebellar vermis (from Latin vermis, “worm”) is located in the medial, cortico-nuclear zone of the cerebellum, which is in the posterior fossa of the cranium. The primary fissure in the vermis curves ventrolaterally to the superior surface of the cerebellum, dividing it into anterior and posterior lobes.
What is the meaning of Floccular?
1 : a small loosely aggregated mass. 2 : a bright or dark patch on the sun.
What is ataxia vs dysmetria?
Ataxia is an unsteady and swaying walk, often with feet planted widely apart. People have difficulty walking a straight line with their heel touching the toe of the shoe in front (the drunk test). Ataxia can occur in a number of neurologic conditions. Dysmetria is misjudging the distance to a target.
What is the role of the vermis?
Vermis (highlighted in red) on the cerebellum. Functionally, the vermis is associated with bodily posture and locomotion. The vermis is included within the spinocerebellum and receives somatic sensory input from the head and proximal body parts via ascending spinal pathways.
