What is the function of the cervical vertebrae?
- C1: The first vertebra in the column closest to the skull is also known as the atlas. It forms the joint that connects the skull and the spinal column.
- C2: Also known as the axis, it creates a pivot that allows C1 to rotate, thus giving the head greater range of motion.
- C7: The last of the cervical vertebrae, C7 has an extra-long spinous process. ...
What are the symptoms of a dislocated vertebrae?
Displacement of the vertebrae of the cervical region can cause serious neurologic pathologies, but the characteristic symptoms can be learned about this pathology: Frequent headaches, migraine, dizziness, drowsiness, a sense of weakness. Violation of the sensitivity of the hands, changes in the work of the shoulder girdle and hands.
What is the name of the second cervical vertebra quizlet?
What is the name of the second cervical vertebra? C2 is known as the axis. It has a bony projection called the odontoid process that articulates with C1.
Is the atlas the second cervical vertebrae?
Introduction. The Atlas (the first cervical vertebra - C1) differs from the other cervical vertebrae in that it has no body or spinous process. It is comprised of two bony arches with two bony masses laterally. It articulates with the Occiput above and C2 (the Axis) below.
Where are C1 and C2 vertebrae?
neckThe C1 and C2 vertebrae are the highest of the spinal vertebrae and are located at the very top of the neck, connecting the head to the spine. The C1 vertebrae is named atlas and the C2 vertebrae is named axis.
What is atlas and axis vertebrae?
The atlas and axis vertebrae are the two most superior bones in the vertebral column, and they are part of the seven cervical vertebrae. The atlas is the top-most bone, sitting just below the skull; it is followed by the axis. Together, they support the skull, facilitate neck movement, and protect the spinal cord.
What is the axis of the cervical spine?
The axis is the second of seven bones in the cervical spine. The axis, also known as the C2 bone, creates a pivot that allows the C1, or atlas, to rotate. This action gives the head and neck a greater range of motion from side to side. The pivoting motion occurs on part of the bone called the dens, a tooth-like upright section on the bone.
What is the pivoting motion of the cervical vertebrae?
The pivoting motion occurs on part of the bone called the dens, a tooth-like upright section on the bone. The dens in the axis is larger than any other vertebral bone. Another special characteristic of the axis and all other cervical vertebrae is the absence of a body, or large flat portion of the bone. Because these two bones lack this body, the ...
How many vertebrae are there in the axis?
The vertebral column, or spinal column, is made up of a total of 33 vertebrae, which are subdivided into five regions: cervical, thoracic, lumbar, sacral, and coccyx.
Why does the neck have the widest range of motion?
Because these two bones lack this body, the neck has the widest range of motion of all the sections of the spinal column. Injury to the atlas or axis, such as fracture from a high-impact collision or sudden, violent jerking of the head, may cause paralysis and it some cases can even be fatal.
What is the typical cervical vertebra?
Typical Cervical Vertebrae. Cervical level three through six are considered typical cervical vertebra and are similar in shape and function. Each vertebra has a vertebral body, arch, and facet joint (one on each side of the vertebra) . The vertebral body is the large cylindrical bone towards the front of the vertebra.
What is the level 2 of cervical rotation?
Cervical level two is called the axis, and has a large bony protrusion called the dens or odontoid process. This bony odontoid process passes up through the ring-like atlas vertebrae and forms the atlantoaxial joint. This is where about 50% to 60% of cervical rotation occurs.
What is it called when you have a slight forward curve in your neck?
There should be a slight forward curve in your neck when the seven cervical vertebrae are stacked upon one another. This curve is called lordosis. Loss of the lordosis may signify spinal muscle spasm or problems with the discs between each cervical vertebra. 2.
What are the atypical vertebrae?
The atypical vertebrae are cervical level one and two (C1 and C2) . Cervical one is also called the atlas, as it supports the weight of your skull. Cervical two is called the axis, as it is the one essential for allowing rotation to occur in the cervical spine. Both the atlas and axis are small, flat vertebrae.
Which vertebrae support the weight of the skull?
The joints of the vertebra allow for flexion, extension, and side bending. The special shape of the first and second cervical vertebrae supports the weight of your skull and allows for significant rotation to happen in your upper cervical spine. This allows you to move your head freely in many different directions.
What is the best way to reduce pain in cervical spine?
Massage: Massage is used to increase blood flow and decrease pain in muscles around your cervical spine. Electrical stimulation: Electrical stimulation, often in the form of transcutaneous electrical neuromuscular stimulation (TENS), may be used to decrease pain and increase local blood flow.
How many bones are there in the neck?
Rehabilitation. Your neck, also known as the cervical spine, is a complex series of bones, discs, muscles, nerves, and ligaments. There are seven bones, each called a cervical vertebra, that are stacked upon one another.
Where is the cervical spine located?
The cervical spineis located at the very top of the spinal column. Besides the atlas C1 and axis C2 cervical vertebrae , there are five additional vertebral levels within this region (for a total of seven) which are classified as C1-C7 from the top down, forming the human neck.
What is the C1 vertebra?
This vertebral formation is only seen in the cervical region. C1 and C2 Vertebrae Names. The C1 vertebra is referred to as atlas—so named for the Greek myth in which the titan Atlas held up the sky. The second vertebra, C2, is called the axis in reference to its purpose — enabling motion.
What is the spinal cord divided into?
For identification purposes, the spinal cord is divided into multiple sections that correspond with the vertebral section of the spine in that area. Read on for more information on the fundamentals of these injuries, expected prognosis, and the latest treatments available.
What is it called when you have a partial paralysis of the neck down?
When someone experiences complete or partial paralysis from the neck down — their trunk and all four limbs — it is commonly referred to as tetraplegia or quadriplegia. An injury to the cervical vertebrae C1 and a C2 spinal cord injury are both considered highly rare injuries to sustain.
What is the most severe spinal cord injury?
Injuries to the cervical spine at the C1 and C2 vertebrae make up just 2% of all spinal cord injuries. While they are considered the most severe of all spinal cord injuries, the effects of these injuries can vary depending on the completeness of the damage. For identification purposes, the spinal cord is divided into multiple sections ...
What is the most severe injury in the C1 and C2 vertebrae?
C1 and C2 Vertebrae Breaks, Fractures, and Misalignments. Atlas C1 and axis C2 injuries are the most severe because damage to the spinal cord at any level has potential to remove communication to the rest of the body below that point.
What happens if you get a C1 and C2 injury?
In addition to the initial vertebral injury, the interference at the C1 and/or C2 level can cause the vertebral arteries to inflict neurological damage; leaving the brain without a vital source of blood. Symptomsfollowing an injury to the cervical vertebrae C1 and C2 may include: Complete paralysis of arms and legs.
