Explanation:

oid space, beneath the arachnoid mater.

1. The pia mater is the thin inner meningeal layer that adheres to brain/spinal cord tissue and contains blood vessels/nerves.
2. A subdural hematoma is bleeding that forms a pressure-causing clot between the dura and arachnoid mater after a head blow.
3. The human spinal cord is divided into 33 total segments: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 3 coccygeal.
4. The inner, butterfly-shaped region of the spinal cord cross-section is gray matter, containing neuron cell bodies.
