Identify the major weight bearing part of a vertebra. The occipital bone articulates with the temporal bones parietal bones and sphenoid bone.
C1 Vertebra The Atlas In The Cervical Spine Supports All Of The Weight Of The Skull Putting Enormous Pre Medical Anatomy Thoracic Vertebrae Vertebral Artery
At the base of skull in the occipital bone there is a large oval opening called the foramen magnum which allows the passage of the spinal cord.
. Inion The INION located just outer to the posterior pole of the occipital cortex is a useful landmark in the placement of the electrodes used to. The c2 or axis has a body and a odontoid process or dens that articulates with. Atlas is the very top of the vertebral column and articulates directly with the occipital bone of the skull.
C2 also known as axis is distinct in that it contains bilateral masses to articulate with C1 a body through which weight is transmitted through C3 and below and an odontoid process or dens on the superior aspect of the body. The occipital bone is a cranial dermal bone and the main bone of the occiput. The base of the occipital bone articulates with the first cervical vertebra atlas or C1 thanks to the condylar part of occiput that anatomically ressambles the processus articularis inferior of cervical vertebra.
It is trapezoidal in shape and curved on itself like a shallow dish. Sinuses take away a minimal amount of strength from while reducing the weight of bones. A strong roughly horizontal ridge runs along the back of the occipital bone onto which the occipital muscle inserts.
Superiorly it joins the parietal bones along a complex suture line and laterally it articulates with the temporal bones. The disk shaped bodies of vertebrae are stable and stackable. Subsequently question is what part of the vertebra is the weight.
A small upwards projection found on the second neck vertebrae. This is the Atlanto-axial joint. In this way has a dens that provides a pivot for rotation of the first cervical vertebra c1.
The superior portion of the sternum is called the xiphoid process. Most weight is distributed in this region. The parietal bones articulate with each other at the midline in the sagittal suture with the occipital bone posteriorly in the lambdoid suture and with the frontal bone anteriorly at the coronal suture.
The occipital bone overlies the occipital lobes of the cerebrum. The atlanto-occipital joint allows the head to nod up and down on the vertebral column. The dens acts as a pivot that allows the atlas and attached head to rotate on the axis side to side.
Like the other cranial bones it. The base of the occipital bone articulates anteriorly with the body of the sphenoid bone. Inferiorly the atlas articulates with the dens which acts as a pivot that allows the atlas and attached head to rotate on the axis.
The type of articulation or joint formed will affect movement. The antebrachium is composed of which of the following two bones. The occipital condyles articulate with the a.
It is also referred to. Though it does not articulate with any other bone the hyoid bone is considered to be part of the axial skeleton. Superiorly the atlas articulates with the occiput to form the Atlanto-occipital joint which allows the head to nod up and down on the vertebral column.
The radius and the ulna. The parietal bone articulates inferiorly with the temporal bone and the greater wing of the sphenoid bone. Click to see full answer.
The dens articulate with the occipital bone TF False. The dens articulates with the occipital bone. Lamina Transverse process Vertebral foramen Body.
The reason behind this is the common somatic origin of the occipital bone and vertebral column. Which of the following can be considered a function of the paranasal sinuses. The dens articulates with the occipital bone.
The dens articulates with the occipital bone. Which region of the vertebral column is located superior to the thoracic region and which region is inferior to the thoracic region respectively. The superior articular facets of these masses contact the occipital condyles of the skull and the inferior facets articulate with superior facets of C2.
The dens odontoid process is a projection on the C2 vertebra called the.
