What structures make up the meninges?

The meninges consist of three protective membranes: the dura mater, arachnoid membrane, and pia mater.

What does the medulla oblongata control?

The medulla oblongata controls autonomic functions, including heart rate and respiratory functions.

What is the role of the cerebellum?

The cerebellum helps coordinate muscular activity, controls posture, and maintains balance.

How do the left and right cerebral hemispheres communicate?

They communicate through a series of myelinated fibers called the corpus callosum.

What is the function of ependymal cells in the brain?

Ependymal cells in the ventricles form the cerebrospinal fluid (CSF) that fills the ventricular system and surrounds the CNS.

What are the two divisions of the autonomic nervous system?

The autonomic nervous system is divided into the sympathetic division and the parasympathetic division.

What is the role of thermoreceptors?

Thermoreceptors respond to changes in temperature.

What is a reflex action?
