VERTEBRAL COLUMN Flashcards
Describe the vertebral body
-Weight bearing part
-Spongy bone covered in compact bone
-Superior and inferior surfaces covered in hyaline cartilage
Attaches the vertebral body to the vertebral arch
Pedicle
Forms the vertebral canal
Vertebral foramen
Vertebral canal consist of
Spinal cord
Projects posterior at the junction of two laminae
Spinous process
Projects posterolaterally at the junction of peicle and lamina
Transverse process
Layers of the meninges
Dura mater
Arachnoid mater
Pia mater
Separates the dura mater from bone
Epidural space
Separates arachnoid mater from pia mater
Subarachnoid space
Innermost layer
Pia mater
How many pairs of spinal nerves are there
31 spinal nerve
Emerges from intervertebral foramina
Spinal nerve
Has no vertebral body
C1 Atlas
What does the lateral masses of C1 vertebra articulate with
Occipital condyles superiorly and superior articular surface of C2 inferiorly
Has posterior and anterior arch
C1 Atlas
What holds the dens in position
Transverse ligament of atlas
Has dens that projects from the vertebral body
C2 Axis
Description of cervical vertebra
Vertebral body- Square shaped
Transverse process has foramen tranversarium
Spinous process- Short and bifid
Vertebral foramen-Triangular
Description of thoracic vertebra
Vertebral body-Heart shaped
Vertebral foramen- Round
Description of lumbar vertebra
Vertebral body- cylindrical
Vertebral foramen- Triangular
Larger in size
Joint formed by the hyaline cartilage and the intervertebral disc between them
Secondary cartilaginous joint
Elevated lateral margins of typical cervical vertebra
Uncinate process
Joint formed by uncinate process articulating with vertebral body above
Uncovertebral joint
Joints formed by articulation of superior articular surfaces and inferior articular surface of adjacent vertebrae
Zygogphyseal joints
Movement of atlanto-occipital joint
Flexion and extention(Nodding)
Movement of atlanto-axial joint
Pivot movement(NO)
