Question

Where does the spinal cord typically terminate?

Answer 1

Hint: The spinal cord is a long, delicate tubelike structure that runs from the end of the brain stem to practically the bottom of the spine. The spinal cord is made up of bundles of nerve axons that form channels that convey messages from the brain to the rest of the body.

Complete answer:
The central nervous system of your body is made up of the brain and spinal cord. The brain serves as your body's command centre, and the spinal cord serves as a conduit for messages conveyed from the brain to the body and from the body to the brain.
The peripheral nervous system is a network of nerve strands that emerge from the left and right sides of the spinal cord through holes in the spinal canal between each vertebra. These nerve pairs run throughout your body, carrying commands from your brain and spinal cord to various bodily components.
The terminal end of the spinal cord is housed in the lower back, which largely encloses the cauda equina—nerve roots that descend from the spinal cord. The cauda equina and the spinal cord are fragile and vital structures. By providing a strong, bony casing, the spinal canal produced by the lumbar vertebrae protects these components.
Spinal Cord of the Lumbar
The lumbar spine is where the spinal cord ends. The exact place of termination varies from person to person, but it usually occurs at the level of the L1 or L2 vertebrae. The lumbar spinal cord has a few anatomical features that are highlighted below.

Note:
The central nervous system and peripheral nervous system work together to allow your brain to manage a variety of tasks in your body, including three key areas (diagram):
1. Motor Functions - controls the voluntary muscle movements of your body.
2. Sensory Functions - monitors touch, pressure, temperature, and pain sensations.
3. Autonomic Functions - controls digestion, urination, body temperature, heart rate, and blood vessel dilation and contraction (blood pressure).
