Vertebral Column Part 1

The statement is true because the zygapophysial joint is indeed another term for a facet joint. Facet joints are located in the spine and connect the vertebrae together, allowing for movement and flexibility. They are synovial joints that have cartilage-covered surfaces and a synovial membrane that produces synovial fluid to lubricate the joint. The zygapophysial joint is the specific name for these facet joints in the spine.

The vertebral arch is indeed made up of two pedicles and two laminas. The pedicles are short, thick processes that connect the vertebral body to the lamina, which are flat plates of bone that form the posterior portion of the arch. Together, the pedicles and laminas enclose the vertebral foramen, which houses the spinal cord. Therefore, the statement "You have one vertebral arch made up of 2 pedicles and 2 laminas" is true.

Rectus capitis minor is a small muscle located at the back of the neck. It originates from the posterior tubercle of the atlas (C1 vertebrae) and inserts into the nuchal line, a ridge on the occipital bone. This muscle is responsible for flexing and rotating the head. Therefore, the statement that Rectus capitis minor attaches to the posterior tubercle of C1 and attaches to the nuchal line is true.

1/3 the size. rest is filled with fluid and other stuff.

it is NOT the lamina, it is a separate piece of bone.

C2 is called greater occipital nerve but C1 is called the suboccipital nerve.

Spina Bifida is a congenital condition where the lamina, a part of the vertebra, fails to close properly, resulting in the incomplete formation of the spinous process. This can lead to a range of complications, including the protrusion of the spinal cord and its covering through the gap in the vertebrae. The other options mentioned in the question are not accurate descriptions of Spina Bifida.

The vertebrae that can be seen in the middle of the suboccipital triangle is C1, also known as the atlas. The suboccipital triangle is a region located at the base of the skull, formed by the superior oblique, inferior oblique, and rectus capitis posterior major muscles. C1 is the first cervical vertebrae and it articulates with the occipital bone of the skull, allowing for flexion and extension movements of the head.

The obliquus capitis inferior is the correct answer because it does not attach to the nuchal line. The nuchal line is a ridge on the occipital bone of the skull, and the obliquus capitis inferior muscle attaches to the spinous process of the axis vertebra, not the nuchal line.

The artery found in the suboccipital triangle is called the vertebral artery.

Ventral rami in the thoracic region don't have plexuses, they just turn into intercostal nerves.

Secondary, you develop when you start picking up your head

The lamina and the pedicle are the components that form the vertebral arch. The lamina is a thin, flat plate of bone that extends from the pedicle and forms the posterior portion of the arch. The pedicle, on the other hand, is a short, thick piece of bone that connects the lamina to the body of the vertebra. Together, the lamina and pedicle provide support and protection to the spinal cord, forming the structure of the vertebral arch.

The correct answer is Rectus capitis posertior major and obliquus capitis inferior. These muscles both have an attachment on SP C2.

The suboccipital triangle is a group of muscles located at the base of the skull. These muscles work together to help rotate the head. When the head is rotated ipsilaterally, it means that it is being turned towards the same side as the muscles in the suboccipital triangle. Therefore, the correct answer is "ipsilaterally".

Cervical and Lumbar vertebrae have a lordotic curve while thoracic and sacral vertebrae have a kyphotic curve. The lordotic curve in the cervical and lumbar regions helps to maintain balance, absorb shock, and provide flexibility in the spine. The kyphotic curve in the thoracic and sacral regions helps to protect the internal organs and provide stability to the spine.

The Rectus Capitis Posterior Major muscle attaches inferior to the spinous process (SP) of the second cervical vertebra (C2) and superior to the nuchal line.
