What is the prevertebral group?
The prevertebral muscles are a group of deep cervical muscles inside the neck located laterally at the upper vertebral column. They are enveloped by the prevertebral layer of the cervical fascia. Their main task is the bending forward of the skull (ventral flexion).
What does prevertebral mean?
Medical Definition of prevertebral : situated or occurring anterior to a vertebra or the spinal column prevertebral muscles.

Which prevertebral muscles flex the atlanto occipital joint?
Rectus capitis lateralis originates from the transverse process of the atlas and inserts onto the jugular process of the occipital bone. It’s innervated by branches from the loop between C1 and C2 spinal nerves and when it contracts, it stabilizes and flexes the atlanto-occipital joint.
What is prevertebral soft tissue?
BACKGROUND AND PURPOSE: Analysis of the prevertebral soft tissue (PVST) is helpful in detecting osseous and ligamentous injuries of the cervical spine. CONCLUSIONS: The thickness of the PVST is important in the detection of underlying injuries to the cervical spine.
What are the names for the paravertebral muscles?
Passing upward, they separate out into three somewhat distinct muscles, the spinalis, the longissimus thoracis, and the iliocostalis lumborum.
What is prevertebral soft tissue swelling?
Objective: Prevertebral soft tissue swelling (PVSTS) is an important marker of spinal trauma. In patients with missed or occult cervical fractures, it may be the only indication of serious injury.
What is prevertebral swelling?
What causes prevertebral soft tissue swelling?
Causes of increased PVST thickness include infection, neoplasm, hemorrhage, and fluid accumulation. In the setting of trauma, severe potentially incapacitating injuries to the cervical spine can present with PVST thickening as the only radiographic sign.
What is the paravertebral region?
Anatomy. The thoracic paravertebral space (TPVS) is a wedge-shaped space located on either side of the vertebral column (Figure 1). The parietal pleura forms the anterolateral boundary. The base is formed by the vertebral body, intervertebral disc, and the intervertebral foramen with its contents.
What are spinal erectors?
The erector spinae muscles are a group of long muscles that originate near the sacrum and extend vertically up the length of the back. The erector spinae muscles lie on each side of the vertebral column and extend alongside the lumbar, thoracic, and cervical sections of the spine.
What is prevertebral abscess?
Prevertebral abscess is one of the uncommon deep neck space infection, occupies the prevertebral space between the vertebrae bodies and prevertebral fascia, and extends from the base of the skull to the coccyx, thus allowing organisms to spread down as far as the psoas muscle sheath [1, 2].
What are the prevertebral muscles of the body?
Prevertebral muscles. 1 Longus capitis muscle. Longus capitis muscle. The Longus capitis muscle originates at the anterior tubercles of the transverse processes of the 3rd to 2 Longus colli muscle. 3 Rectus capitis anterior and lateralis muscles. 4 Clinical notes.
What muscles make up the prevertebral layer of the neck?
Together with rectus capitis anterior, rectus capitis lateralis, longus cervicis and anterior scalene muscle, it makes the prevertebral layer of neck muscles. These muscles are wrapped up in the prevertebral layer of the cervical fascia.
Where does the longus colli muscle insert?
This muscle section inserts onto the anterior surface of bodies of second, third and fourth cervical vertebrae (C2-C4). Inferior oblique part – is the smallest section of the longus colli muscle. It arises from the anterior surfaces of bodies of first three thoracic vertebrae (T1-T3).
What is the function of the cervical flexor muscles?
These muscles are active in flexion and lateral flexion of the neck in the cervical region, and flexion at the atlanto-occipital joint. They play an important role in the stabilization of the cervical vertebral column, counteracting the cervical extensors.
