What are the spinous processes?
Spinous process is a bony projection off the posterior (back) of each vertebra. The spinous process protrudes where the laminae of the vertebral arch join and provides the point of attachment for muscles and ligaments of the spine.
Where is the vertebral foramen?
The vertebral canal is composed of the vertebral foramen located in the cervical, thoracic, and lumbar vertebrae. The vertebral or spinal canal typically ends at the level of the L2 vertebra, where the spinal cord gives off multiple branching spinal nerve and nerve rootlets known as the cauda equina.
What are typical cervical vertebrae?
C3, C4, C5, and C6 cervical vertebrae. Cervical vertebrae C3 through C6 are known as typical vertebrae because they share the same basic characteristics with most of the vertebrae throughout the rest of the spine. Typical vertebrae have: Vertebral body.
What goes through the foramen Transversarium?
The transverse processes are each pierced by the foramen transversarium,which, in the upper six vertebræ, gives passage to the vertebral artery and vein and a plexus of sympathetic nerves.
Where are foramen Transversarium found?
cervical vertebrae
Foramen transversarium (FT) are bony canals found only in the transverse processes of cervical vertebrae ( Dofe et al., 2015; Mulla & Pundge, 2015).
What muscles attach to the spinous process?
Because the spinous processes are so short, certain superficial muscles (the trapezius and splenius capitis) attach to the nuchal ligament rather than directly to the vertebrae; the nuchal ligament itself attaching to the spinous processes of C2-C7 and to the posterior tubercle of the atlas.
Can you feel spinous process?
A spinous process is the thin, bony projection that extends off the back of each vertebrae. If you run your hand down your back, you can feel the spinous processes.
What does each cervical vertebrae control?
C1, C2, and C3 (the first three cervical nerves) help control the head and neck, including movements forward, backward, and to the sides. The C2 dermatome handles sensation for the upper part of the head, and the C3 dermatome covers the side of the face and back of the head. (C1 does not have a dermatome.)
Where is the supraorbital notch in the skull?
The skull from the front. The supraorbital foramen, is a bony elongated opening located above the orbit (eye socket) and under the forehead. The supraorbital foramen lies directly under the eyebrow. Sometimes this foramen is incomplete and is then known as the supraorbital notch.
What is the structure of the supraorbital foramen?
Structure. The supraorbital foramen arches transversely below the superciliary arches and is the upper part of the brow ridge, thin and prominent in its lateral two-thirds, rounded in its medial third, and presenting, at the junction of these two portions, the supraorbital foramen or notch for the supraorbital nerve and vessels…
Where does the term foramen transversarium come from?
The term [ foramen transversarium] is Latin for “transverse foramen “. It refers to bilateral foramina (openings) found lateral to the vertebral body in the cervical vertebrae. These foramina are found only in cervical vertebrae and serve as a good way to identify them.
