Q

Where does the Alar Ligament attach?

A

The alar ligament is a thick fibrous cord that attaches to the lateral aspect of the dens/odontoid process and inserts on the medial aspect of the occipital condyle

18
Q

What is the function of the Alar Ligament?

A

Limits axial rotation and lateral flexion of the head

19
Q

Where does the Cruciate Ligament attach?

A

Consists of two bands: Longitudinal band: joins the body of the C2 (axis) to the foramen magnum/occipital bone. Transverse band: attaches to the inner margin of the C1 (atlas) lateral masses on both sides

20
Q

What is the function of the Cruciate Ligament?

A

Limits Up and down nodding motion of the head

21
Q

History of Coccyx

A

Remnant of the skeleton of the embryonic tail-like caudal eminence which was present in human embryos from the end of the 4th week until the beginning of the 8th week.

22
Q

Layman’s term for coccyx?

A

Tailbone

23
Q

What kind of joints are Zygopophysial Joints?

A

Synovial joints
(aka apophysial jt or facet jt)

24
Q

How are Zygapophysial joints/facets oriented in Cervical Vertebrae?

A

at a 45 degree angle

25
Q

How are Zygapophysial joints/facets oriented in Thoracic Vertebrae?

A

facing backward

26
Q

How are Zygapophysial joints/facets oriented in Lumbar Vertebrae?
