Name the condition:  Disordered contractions of agonist and antagonist muscles, and lack of normal coordination between movements at different joints.

These movements have abnormal timing or ____

These movements ahve abnormale trajectories through space or ____

Most cerebellar connections are _______ or they will cross the brain _______ so malfunctioning in the cerebellum will always manifest on the same side of the body.

What are 3 I's of Cerebellar Stroke?

The _______ and  ______ aid in Truncal Movements (Midline cerebellum)

 The ________ hemispheres aid in Ipsilateral Skilled movements (Neocerebellum)

 Stroke of Neocerebellum results in (3 major manifestations)

A disruption of the _______  ______-_______ ______ pathway would cause a NON-CEREBELLAR ATAXIA. 

It is a _______ ataxia that can be proven with a positive Romberg test.  It is positive because the condition is improvable with visual feedback.

Dr. Goss Part: 

The ____ _____ seperates the Cerebellum from the Cerebrum

 Cerebellum actions do/do not reach conscious awareness?

Situationed on the ______ ______ Fossa

Transverse Cerebellar Lobe name it: A)Oldest, related to vestibular part of VIII and thus helps to regulate equilibrium through the vestibulotract

B)Rostral to primary fissure, general sensory receptors, concerned with muscle tone and walking

C)Newest, and largest, receives afferent projections from contralateral sensorimotor cortex, FUNCTIONS IN COORDINATION OF FINE AND SKILLED MOVEMENTS

Longitudinal Cerebellar regions:

A)Contributes to body posture

B) Regulates movements of ipsilateral extremities (walking)

C) Regulates skilled movements of extremity (tying your shoe)

Deep Cerebellar Nuclei

A) Largest communicates through cerebellar penuncle, carries information important for coordination of limb movements B) Regulates body posture, is related to the flocculo nodular lobe C)one half of interposed nuclei, regulates movements of ipsilateral extremityD)other half does same thing as C)

Cerebellar Connections or Peduncles Name em:

1) Afferent: mediate sensorimotor input to cerebellum

2)afferent....same as 1

3) Efferent: transmit output from cerebellum to brainstem and on to thalamus, motor cortex, and spinal cord

Afferent:Efferent Ratio?

The __________ tract includes the posterior and anterior __________ tracts
Carries sensation to the cerebellum concerning position of muscles, tendons (such as, _____ _____ organs) and joints

Name Afferent Tracts of the Inferior Peduncle (5)

More Afferent Pathways (Medial Peduncle)

Info comes from opposite cerebral cortex, and give _____ and ______ inputs.

EFFERENT pathways:  go through _____cerebellar peduncle.  Arise from ______, ______, and ______ Nuclei and are routed to the ______ _____ of the brainstem, the _____ and the ______ ____.
