lecture flashcards part 4
alantooccipital joint
yes joint, between the atlas and skull, flexion and extension movement
transverse ligament of the atlas
holds dens against fovea dentis
apical ligaments of the dens
holds dens to the floor of the vertebral column
Wobbler’s syndrome
intervertebral disc or cervical bone malfomation/disease that causes spinal cord compression therefore leads to a wobbly gait
intercapital ligaments
connect the heads of bilateral ribs 2-10, located between thoracic IVD and the dorsal ligament, adds support to dorsum IVD, less bulging discs seen
cauda equine syndrome
abnormal narrowing that causes impingement on the cauda equina
sacroiliac joint
composite joint (synovial and fibrocartilaginous)
conus medullaries
terminal tapering of the spinal cord
lateral vertebral foramina
first pair of spinal nerves
intervertebral formaina
cervical spinal nerves 2-7 emerging cranial to correspondent vertebrae
cranial nerve 8
emerges caudal to C7 and cranial to T1 through intervertebral foramina
thoracic and lumbar spinal nerves
intervertebral foramina caudal to their corresponding vertebrae
sacral formina
first 2 sacral nerves emerge through
last sacral nerve
emerges intervertebral foramina between sacrum and first caudal vertebrae
epaxial muscles
lie dorsal to the transverse processes of vertebrae, extend vertebral column
hypaxial muscles
lie ventral to vertebral bodies and transverse process, main flexors of vertebral column
medial group epaxial muscles
transversospinalis system
intermediate group epaxial muscles
longissimus system
lateral group epaxial muscles
iliocostalis system
location of iliocostalis system
located in lumbar and thoracic region
location of longissimus system
located in lumbar and thoracic and cervical regions
transcersospinalis system parts
splenius and semispinalis capitis
semispinalis capitis parts
biventer cervicic and complexus
cervical hypaxial muscles
longus colli and longus capitis
location of longus colli
located in the ventral surfaces of cervical and thoracic vertebral bodies
longus capitis
located ventral to and has attachments to the cervical vertebrae, lies lateral to cervical part of longus coli
contents of cervical visceral space
trachea, esophagus, carotid sheath
carotid sheath
common carotid arteries, vagosympathetic nerve trunks, internal jugular veins
