Regions of the Spine: Lumbar
The spinal region found in your lower back. You have five vertebrae in this region.
Got it
Thoracic Nerves
These nerves are found in your thoracic region. You have twelve pairs of them. They are labeled with the letter 'T.'
Got it
Regions of the Spine: Thoracic
The region of your spine in your chest or trunk, offering protection to your heart and lungs. There are twelve vertebrae in this region. They connect to the ribs.
Got it
Cervical Nerves
We have eight pairs of these nerves. They are found in the cervical region of our spine. They are labeled with the letter 'C.'
Got it
Regions of the Spine: Cervical
This portion of the spine begins at the base of your skull and makes up your neck. It contains seven vertebrae.
Got it
Spinal Cord
The area inside your vertebrae. Our spinal nerves extend outward from this area.
Got it
Vertebrae
The bones that make up our spine. They have irregular shapes. We have 33 of these bones.
Got it
Spinal Nerves: Function
These nerves play two important roles in our body. They bring our central nervous system sensory information, and they carry motor signals to different regions of our body.
Got it
Spinal Nerves
The nerves found around our spinal cord. They are separated into five groups based on the region of the spine where they are located.

Flashcard Content Overview

You can use these flashcards to review the five regions of your spine where spinal nerves are found. Go over the method used to name these nerves. You'll also be able to focus on the nerve plexuses found in the human back and to consider the spinal nerves found in each plexus.

Spinal Nerves
The nerves found around our spinal cord. They are separated into five groups based on the region of the spine where they are located.
Spinal Nerves: Function
These nerves play two important roles in our body. They bring our central nervous system sensory information, and they carry motor signals to different regions of our body.
Vertebrae
The bones that make up our spine. They have irregular shapes. We have 33 of these bones.
Spinal Cord
The area inside your vertebrae. Our spinal nerves extend outward from this area.
Regions of the Spine: Cervical
This portion of the spine begins at the base of your skull and makes up your neck. It contains seven vertebrae.
Cervical Nerves
We have eight pairs of these nerves. They are found in the cervical region of our spine. They are labeled with the letter 'C.'
Regions of the Spine: Thoracic
The region of your spine in your chest or trunk, offering protection to your heart and lungs. There are twelve vertebrae in this region. They connect to the ribs.
Thoracic Nerves
These nerves are found in your thoracic region. You have twelve pairs of them. They are labeled with the letter 'T.'
Regions of the Spine: Lumbar
The spinal region found in your lower back. You have five vertebrae in this region.
Lumbar Nerves
Humans have five pairs of these nerves in the lumbar region of their spine. We label them with the letter 'L.'
Regions of the Spine: Sacral
This region of the spine is located at the pelvis. The five vertebrae located in this region have fused together.
Sacral Nerves
Nerves found in the sacral region of the spine. We have five pairs of these nerves and label them with the letter 'S.'
Regions of the Spine: Coccygeal
The region of the spine that forms the tailbone. This bone formed from the fusion of four smaller bones during childhood.
Coccygeal Nerves
You have one pair of this kind of nerve, found in your coccygeal region. We label this pair of nerves with the letters 'Coc.'
Nerve Plexuses
Nerve networks made up of several spinal nerves. We have four major examples of this in our spine.
Cervical Plexus
A network of nerves that contains nerves C1 through C5 in our necks. This plexus sends signals to the neck and shoulders.
Brachial Plexus
This nerve plexus is made of the nerves C5-T1. This plexus sends signals to the arms and upper back.
Lumbar Plexus
The network of nerves found in our lower backs. It contains the L1 through L4 nerve pairs. This plexus sends signals to the abdomen and leg muscles.
Sacral Plexus
The nerve pairs L4 through S4 make up this plexus. This group of nerves can spend messages to areas in our lower body.
