cervical anatomy session Flashcards
the musculoskeletal system works together to provide the body with what
support,protection and movement
the vertebral column consists of what
cervical,lumber,thorax,sacral and coccygeal
characteristics of the cervical vertebrae
small size
saddle-shaped body
bifid spinous process
characteristics of the atlas vertebrae
has no bifid spinous process and no vertebral body
connects the skull and spine
articulates with the occiput and the axis
has a lateral mass connected by the anterior and posterior arch
function of the atlas ligament
maintains the odontoid process
functions of the alar ligament
limits the axial rotation in the occipital alanto axial complex and side bending
it is the most stretched ligament when the head is rotated and flexed
features of the axis ligament
forms a pivot for the atlas to rotate
has a vertebral body and foramen
heavy pedicles and laminae
has a strong odontoid process
has a transverse process
where does the nucal ligament start from and end to
external occipital protuberence
and atlas and ends in c7
the cervical plexus consists of cervical
c1-c5
the brachial plexus consists of
c6-t1
what are the two types of nerve roots
dorsal root
ventral root
funtions of the dorsal root
carries SENSORY signals back to the brain from the nerve root DERMATOME which innervates the SKIN
functions of the ventral root
carries MOTOR signals AWAY from the brain to the nerve roots MYOTOME which innervates the MUSCLES
The merging of the dorsal and ventral roots makes up what
the spinal nerve
where does the ventral and dorsal root merge
intervertebral foramen
