The basal ganglia are involved in the regulation of voluntary motor movements, procedural learning, and routine behaviors. They help to inhibit unwanted movements.

2.

FLASHCARD QUESTION

Front

What happens when the basal ganglia are damaged?

Back

Damage to the basal ganglia can lead to reduced inhibition of the thalamus, resulting in involuntary movements, as seen in conditions like Huntington's disease.

3.

FLASHCARD QUESTION

Front

What is the function of the cerebellum?

Back

The cerebellum coordinates voluntary movements, balance, and motor learning. It contains more than half of the brain's neurons.

4.

FLASHCARD QUESTION

What are saccades?

Back

Saccades are rapid movements of the eye that change the point of fixation. Inaccurate saccades can indicate dysfunction in the cerebellum.

5.

FLASHCARD QUESTION

Front

How does cold water affect fish movement?

Back

In cold water, fish can move rapidly but fatigue easily due to muscle stiffness and reduced metabolic efficiency.

6.

FLASHCARD QUESTION

Front

What is the primary target of the motor cortex's axons?

Back

The motor cortex sends its axons primarily to the medulla and spinal cord, which then relay signals to the muscles.

7.
