Unlike the spinal cord, the outer portion of the brain is made up of matter, while the inner portion is made up of matter.
Gray, white
All ventricles of the brain are paired, except for the fourth ventricle.
True. The ventricles are found deep within the brain and serve as cavities for the flow of CSF. The most superior ventricles are the lateral ventricles, and these are the only paired ventricles. Next in sequence is the third ventricle followed by the fourth ventricle, neither of which are paired.

Dopamine
Spinocerebellar tract axons carry sensory information into the cerebellum by the ____
middle cerebellar peduncle
Which areas of the medulla oblongata are activated as a gymnast walks along a narrow plank? Select all that apply.
Inferior olivary nucleus, gracile nucleus, pyramids, and vestibular nuclei are involved in motor and sensory to the body, helping the gymnast to feel the plank and walk across it.
After suffering a blow to the back of the head, Phil loses his vision. The blow probably caused damage to the
