What is the movement between C1 and C2 synovial pivot joint?
This joint forms a pivot motion. When you turn backwards rapidly to open a door or when a dancer pivots on one foot these are the motions a pivot allows. In the joint between C1 and C2, this pivot allows you to turn your head to the left and to the right.
What does the occipital condyle articulate with?
The occipital condyle articulates with the first cervical vertebra (atlas) to form the atlanto-occipital joint. This joint allows for nodding movements of the head.
What movement of the head will be allowed by the atlas?
The atlas, the first cervical vertebra, allows for nodding or tilting movements of the head, such as flexion and extension. It is responsible for the up-and-down movement and supports the skull. Rotation movements are limited at the atlas due to its structure and function in articulation with the axis.
What term best describes the joint at the top of your skull?
The joint at the top of your skull is called the atlanto-occipital joint. It connects the base of your skull (occipital bone) to the top of your spine (atlas bone) allowing for nodding motions of the head.
What is atlanto-occipital joint?
it is one among the craniovertebral joints. it is an ellipsoid type of synovial joint. articulating bones: proximally- occipital condyles. distally- superior articular facests of the atlas. movements: flexion, extension and lateral flexion of neck.
Does nodding the head yes involve movement at the same joint as shaking the head no?
Yes, both nodding the head yes and shaking the head no involve movement at the same joint of the neck, which is the cervical spine. The difference lies in the direction and range of motion of the movement that is performed.
What class lever is nodding head?
Nodding the head is an example of a third-class lever, where the effort is applied between the fulcrum (neck joint) and the resistance (head).
Which joint in the neck causes a yes or a no response movement?
The atlanto-occipital joint allows for the "yes" movement, enabling the head to nod up and down. In contrast, the atlantoaxial joint facilitates the "no" movement, allowing the head to rotate from side to side. Together, these joints enable a range of motion in the neck, supporting both nodding and shaking gestures.
What is the movement between C1 and C2 synovial pivot joint?
This joint forms a pivot motion. When you turn backwards rapidly to open a door or when a dancer pivots on one foot these are the motions a pivot allows. In the joint between C1 and C2, this pivot allows you to turn your head to the left and to the right.
The joint between the atlas C1 and occipital bone that produces yes movement is classified as?
The joint between the atlas (C1) and the occipital bone that allows for the "yes" movement (nodding the head) is classified as a condyloid joint. This type of joint permits flexion and extension, allowing the head to tilt forward and backward. The articulation between the rounded condyles of the occipital bone and the superior articular facets of the atlas facilitates this movement.
What part of the occipital bone forms a joint with the atlas?
It is one of the atlanto-occipital joints which is a subcategory of the craniovertebral joints. It aids in the nodding of the head.
What does the occipital condyle articulate with?
The occipital condyle articulates with the first cervical vertebra (atlas) to form the atlanto-occipital joint. This joint allows for nodding movements of the head.

Rotation movements are limited at the atlas due to its structure and function in articulation with the axis.
What are the functions and importance of the muscles of the back of the head in relation to overall head and neck movement?
The muscles at the back of the head help support the head and neck, allowing for movements like tilting, turning, and nodding. They also play a role in maintaining posture and stability. These muscles are important for overall head and neck movement and help in various daily activities like looking around, nodding, and maintaining balance.
What term best describes the joint at the top of your skull?
The joint at the top of your skull is called the atlanto-occipital joint. It connects the base of your skull (occipital bone) to the top of your spine (atlas bone) allowing for nodding motions of the head.
List all the first class levers in the body?
Three examples of first-class levers in the body are the atlanto-occipital joint (for nodding the head), the elbow joint (for extending the forearm), and the temporomandibular joint (for opening and closing the jaw).
How can you not know to say no?
