Where is C3 C7 on the spine?
C3-C7 Vertebrae, Cervical Discs, Supporting Structures At the back of the vertebral body are bony arches that project outward to form the facet joints and spinous processes.
What nerves are affected by C7?
C7 helps control the triceps (the large muscle on the back of the arm that straightens the elbow) and wrist extensor muscles. The C7 dermatome goes down the back of the arm and into the middle finger. C8 helps control the hands, such as finger flexion (handgrip).
Where is C3 C5 discs on neck?
The C3, C4, and C5 vertebrae form the midsection of the cervical spine, near the base of the neck.
Where is l11 in the spine?
The eleventh thoracic vertebra (T11) is located near the bottom of the thoracic spine. Generally, the spinal bones are larger and heavier the further down they are located.
What is a C3 spinal cord injury?
A C3 spinal cord injury results in quadriplegia, which refers to paralysis of the arms, trunk, and legs. Depending on the severity of your spinal cord injury, you may be able to move and/or feel sensation below your level of injury.
What are the symptoms of a pinched nerve at C3 C4?
Pinched nerve symptoms
- pins and needles.
- muscle weakness.
- burning sensation.
- numbness.
- pain that radiates outward.
- pain when moving your neck or head.
- poor neck range of motion.
What are the symptoms of a pinched nerve at C7?
When the C7 nerve is compressed or irritated, additional complaints may follow, such as:
- Pain from the neck radiating to the shoulder down to the middle finger.
- Numbness in the palm, index finger, and middle finger.
- Weakness in the upper arm, forearm, elbow, and wrist; affecting the motion of these regions.
What nerves are affected by C3?
Branches of the C3, C4, and C5 spinal nerves form the phrenic nerve that innervates the diaphragm, enabling breathing. Within the spinal canal of each of these motion segments, the spinal cord is protected by the vertebral bodies in front and vertebral arches at the back.
How serious is a spinal compression fracture?
What are possible complications of a compression fracture? Complications of compression fractures include: Fractured bones that do not heal after treatment, which can lead to damage of the nearby vertebrae. Blood clots in the legs due to decreased mobility.
What are the symptoms of L5 nerve damage?
L5 NERVE ROOT DAMAGE A pinched L5 nerve root usually results in radiating pain in the foot. This pain can come in the form of numbness, tingling, weakness and shooting and is commonly felt in the big toe, inside of the foot, top of the foot and ankle.
What parts of the body will be paralyzed with a C3 spinal cord injury?
Is the C7 a thoracic or cervical vertebrae?
As the transitional vertebra between the cervical and thoracic regions, the C7 has some features of both the cervical and thoracic vertebrae. Like the C3 through C6 vertebrae, C7 has a thicker area of bone called the body, located anterior to the vertebral foramen. The body of C7 supports the collective weight of the head and neck.
How does the C7 support the head and neck?
The body of C7 supports the collective weight of the head and neck. Facets lateral to the C7’s body allow the C7 to form joints with the C6 vertebra above it and the T1 below it.
What is the relationship between C3, C4, and C5 vertebrae?
The Relationship Between the C3, C4, & C5 Vertebrae The C3,C4, and C5 vertebrae are part of the cervical spinal column. There are seven vertebral levels in total in this region, known as C1-C7. These vertebrae protect the spinal cord running through the cervical region of the spine, as well as provide support for the neck and head.
What are the facets and disks of the C7?
Facets lateral to the C7’s body allow the C7 to form joints with the C6 vertebra above it and the T1 below it. Fibrocartilaginous disks above and below the C7’s body provide cushioning. The facets and disks surrounding the body provide both stability and flexibility to the neck.
