10 Questions
What is the most unique anatomical feature of the cervical vertebrae?
The presence of transverse foramina
What is the primary function of the high degree of mobility in the cervical vertebrae?
To facilitate rotation and flexion of the neck
What is the function of the transverse foramina in the cervical vertebrae?
To allow the vertebral artery to ascend towards the foramen magnum
Where is the vertebral artery located in the neck region?
Anterior to the exiting spinal nerve roots
Which of the following statements about the cervical vertebrae is NOT true?
The high mobility is essential for the limited range of motion (ROM) required by the head.
What is the significance of the high degree of mobility in the cervical vertebrae?
It allows for a greater range of motion in the head and neck
What is the primary function of the transverse foramina in the cervical vertebrae?
To facilitate the passage of the vertebral artery towards the foramen magnum.
In relation to the exiting spinal nerve roots in the neck region, where is the vertebral artery located?
Immediately anterior to the exiting spinal nerve roots.
Which of the following statements best describes the relationship between the cervical vertebrae and the range of motion (ROM) of the head?
The cervical vertebrae have a high degree of mobility, which is essential for the large ROM required by the head.
Based on the information provided, which of the following statements is correct regarding the vertebral artery?
It ascends through the transverse foramina towards the foramen magnum, supplying blood to the brain and spinal cord.
Study Notes
Cervical Vertebrae Characteristics
- Cervical vertebrae are the smallest and most mobile of all movable vertebrae.
- High degree of mobility is essential for the large range of motion (ROM) required by the head.
Unique Anatomic Feature
- The presence of transverse foramina within the transverse processes is the most unique anatomic feature of cervical vertebrae.
Vertebral Artery Pathway
- Vertebral artery ascends through the transverse foramen, coursing toward the foramen magnum.
- The vertebral artery transports blood to the brain and spinal cord.
Location in the Neck
- In the neck, the vertebral artery is located immediately anterior to the exiting spinal nerve roots.
Test your knowledge on the smallest and most mobile vertebrae in the spine, necessary for the head's wide range of motion. Learn about the unique anatomical features like transverse foramina and the vertebral artery's path for blood supply to the brain and spinal cord.
