What is the difference between cerebral reflex and a spinal reflex?
There are two major differences between the dura of the brain and the dura of the cord. The dura of the brain consists of two layers; the periosteal layer is attached directly to the inner surface of the skull and the meningeal layer is deep to the periosteal layer. In places, the two layers are fused together; in other places, dural sinuses lie between the two layers. There is no epidural space associated with the brain

31 pairs. And they arise from the combination of the ventral and dorsal roots.
What structure passes through each intervertebral foramen?
A spinal nerve passes through each intervertebral foramen. These nerves exit the spinal cord and branch out to various parts of the body to facilitate communication between the brain and the rest of the body.
How many pairs of dorsal nerves are there?

How spinal nerves are numbered?
Spinal nerves are numbered according to the region of the spine from which they emerge. There are 31 pairs of spinal nerves: 8 cervical (C1-C8), 12 thoracic (T1-T12), 5 lumbar (L1-L5), 5 sacral (S1-S5), and 1 coccygeal (Co1). Cervical nerves are numbered based on the vertebrae below which they exit, while thoracic, lumbar, sacral, and coccygeal nerves correspond to the vertebrae above which they emerge. This numbering system helps to identify the specific nerve and its associated functions in the body.

The five pairs of lumbar spinal nerves are L1, L2, L3, L4, and L5. These nerves emerge from the lumbar region of the spinal cord and are part of the larger group of spinal nerves that branch out to innervate various body regions. Each pair corresponds to a specific vertebral segment in the lower back.
