Which structures make up the brain stem?
The brainstem is the structure that connects the cerebrum of the brain to the spinal cord and cerebellum. It is composed of four sections in descending order: the diencephalon, midbrain, pons, and medulla oblongata.
What is the pia mater made of?
7.1. The pia mater of the spinal cord is comprised of collagen and reticular fibers. The reticular tissue is wrapped closely around the spinal cord and passes posteriorly into the anterior median fissure. The collagen fibers are external to the reticular fibers forming bundles.
