Cerebellum Anatomy - Active Recall Method

Flashcards covering the anatomy, functions, and clinical correlations of the cerebellum.

Cerebellum

Located in the posterior cranial fossa, below the occipital lobes.

Tentorium cerebelli

The structure that separates the cerebellum from the cerebrum.

Cerebellar peduncles

Three structures that connect the cerebellum to the brainstem.

Hemispheres

The main divisions of the cerebellum, consisting of two hemispheres and a central vermis.

Folia

The surface folds of the cerebellum.

Anterior Lobe

The lobe of the cerebellum that controls muscle tone and posture.

Posterior Lobe

The lobe of the cerebellum that coordinates voluntary movements.

Flocculonodular Lobe

The lobe of the cerebellum that controls balance and eye movement.

Vestibulocerebellum

Functional part of the cerebellum that controls balance and eye movements.

Spinocerebellum

Functional part of the cerebellum that controls posture and limb movements.

Cerebrocerebellum

Functional part of the cerebellum involved in motor planning and coordination.

Superior Cerebellar Peduncle

Sends output from the cerebellum to the midbrain.

Middle Cerebellar Peduncle

Receives input from the pons.

Inferior Cerebellar Peduncle

Receives input from the medulla.

Cerebellar cortex

The outer layer of the cerebellum, composed of gray matter.

Arbor vitae

The inner structure of the cerebellum that transmits signals, consisting of white matter.

Deep cerebellar nuclei

Includes Dentate, Emboliform, Globose, and Fastigial nuclei.

Blood Supply

Supplied by the Superior Cerebellar Artery, Anterior Inferior Cerebellar Artery, and Posterior Inferior Cerebellar Artery.

Motor Coordination

Function of the cerebellum that ensures smooth, accurate movements.

Balance & Posture

Function of the cerebellum that maintains equilibrium.

Muscle Tone Regulation

Function of the cerebellum that controls muscle contraction.

Cognitive & Emotional Role

Minor role of the cerebellum in thinking and emotions.

Ataxia

A condition resulting from damage to the cerebellum, characterized by loss of coordinated movement.

Dysmetria

Inability to judge distance, often associated with cerebellar damage.

Intention Tremors

Tremors that occur when moving, due to cerebellar dysfunction.

Nystagmus

Rapid, involuntary eye movements resulting from cerebellar damage.
