• To withdraw a limb from a painful stimulus

• To compensate for a stimulus on the other side of the body

• To prevent strain and tear injuries to muscles and tendons

• To understand words and effectively communicate with others

What is the function of the crossed-extensor reflex?

• To withdraw a limb from a painful stimulus

What is Wernicke's aphasia?

• A language disorder that makes it difficult to understand words and effectively communicate with others

• A language disorder that makes forming words and sentences difficult

• A blood clot that stops blood supply to an area of the brain

• Blood leakage into brain tissue

What is the corpus callosum and how is it related to split brain patients?

• Typically performed in patients with uncontrollable seizures

• A band of nerve fibers connecting the 2 hemispheres of the brain

• Takes information from one hemisphere to the other

• Disconnects the 2 hemispheres of the brain by cutting the corpus callosum
