What class of lever is a skull pivoting on a vertebra?
yes of course
Referring to the skull what is the atlas?
It is the the most superior (first) cervical vertebra of the spine.
What is the dens odontoid process?
Since the dens is part of the Axis vertebra (and project up in the first vertebra, the Atlas vertebra that supports the skull) it is called the Dens Axis
What type of joint is formed between the atlas and odontoid process?
The Odontoid Process is articulated with the C2 vertebrae [Axis] & is a synovial joint-type. The atlas [C1] is also a synovial-type articulation, but is associated with the Occipital Condyle [directly with the skull]
Where is the atlas vertebrae found?
It's the first cervical vertebra located just beneath the skull
What bone's articulate with the atlas?
The atlas articulates with the axis. The atlas is the first cervical vertebra and articulates with the skull superiorly, and the axis (the second cervical vertebra) inferiorly. The joint between the atlas and axis, dubbed the atlanto-axial joint, is responsible for the increased range of motion of the skull (turning your head left/right, and nodding up/down).The order of the atlas and axis can be remembered because, beginning from the skull, these two cervical vertebrae are in alphabetical order (aTlas then aXis).
Does the atlas bone have spinous process?
No it doesn't. The atlas is the first cervical vertebra and the only one with no spinous process.
What vertebra has no body?
The atlas (C1) is the vertebra that has no body. It is the uppermost cervical vertebra and is specialized for supporting the skull's weight and allowing for the nodding motion of the head.
What vertebra does not have a body?
The atlas (C1 vertebra) does not have a body. It is the topmost vertebra of the spine and is responsible for supporting the skull's weight and allowing for the nodding motion of the head.
