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. This lobe is also involved in the maintenance of balance equilibrium and muscle tone.
What are the functional divisions of the cerebellum?
There are three functional areas of the cerebellum – the cerebrocerebellum, the spinocerebellum and the vestibulocerebellum. Cerebrocerebellum – the largest division, formed by the lateral hemispheres.
What is the function of the flocculonodular lobe of the cerebellum?
The flocculonodular lobe, the first section of cerebellum to evolve, receives sensory input from the vestibules of the ear; the anterior lobe receives sensory input from the spinal cord; and the posterior lobe, the last to evolve, receives nerve impulses from the cerebrum.
What does the anterior lobe of the cerebellum?
The anterior lobe of cerebellum is the portion of the cerebellum responsible for mediating unconscious proprioception. Inputs into the anterior lobe of the cerebellum are mainly from the spinal cord. It is sometimes equated to the “paleocerebellum”….

What is Flocculonodular?
aka vestibulocerebellum, region of the cerebellum that receives vestibular and visual information; it is involved with balance, vestibular reflexes, and eye movements.
What is the function of the Spinocerebellum?
The spinocerebellum receives somatosensory input from both the ipsilateral face (through the trigeminal nucleus) and body (through the dorsal column of the spinal cord). The primary function of the spinocerebellum is coordination of motor movements and maintenance of muscular tone.
What are the 3 functions of the cerebellum?
The cerebellum (which is Latin for “little brain”) is a major structure of the hindbrain that is located near the brainstem. This part of the brain is responsible for coordinating voluntary movements. It is also responsible for a number of functions including motor skills such as balance, coordination, and posture.
What separates the anterior and posterior lobes of the cerebellum?
primary fissure
The anterior lobe is separated from the posterior lobe by the primary fissure, and the posterolateral fissure separates flocculonodular lobe from the posterior lobe. Sometimes, the posterior lobe of cerebellum is called the neocerebellum since phylogenetically it is the newest part of the cerebellum.
What does the Paleocerebellum do?
vertebrate nervous systems …of the cerebellum represents the paleocerebellum, an area that regulates equilibrium and muscle tone. Receiving input from the cerebral hemispheres via the middle cerebellar peduncle, the neocerebellum is the part most concerned with coordination of voluntary motor function.
Where is the Flocculonodular lobe?
cerebellum
aka vestibulocerebellum, region of the cerebellum that receives vestibular and visual information; it is involved with balance, vestibular reflexes, and eye movements.
How are the lobes of the cerebellum divided?
There are three ways that the cerebellum can be subdivided – anatomical lobes, zones and functional divisions There are three anatomical lobes that can be distinguished in the cerebellum; the anterior lobe, the posterior lobe and the flocculonodular lobe. These lobes are divided by two fissures – the primary fissure and posterolateral fissure.
What is the function of 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.
Where is the functional division located in the cerebellum?
In the flocculonodular lobe of the cerebellum, the functional division located is the vestibulocerebellum and as the name suggests it monitors reflexes of eye movements.
What are the flocculonodular appendages?
The flocculonodular lobe consists of two small wispy appendages, known as flocculi, in the posterior and inferior region of the cerebellum. The flocculi are separated by the nodulus, the inferior part of the vermis.
