Week 2 - Cervical Region Flashcards
(51 cards)
Involved with deglutition
located at the base of the mandible at the level with the third cervical vertebra (C3)
Hyoid
the body is at the level of C4-C5
Thyroid Cartilage
At the level of C6
Cricoid cartilage
attachment site for trapezius and nuchal ligament
external occipital protuberance
just lateral ot hte EOP
attachment site for trapezius, occipitofrontalis, SCM, and splenius capitis
Superior nuchal line
Attachment site for occipitofrontalis, sternocleidomastoid and splenius capitis
Contains air cells
mastoid processes
Below the mastoid process and further midline.
Attachment site for rectus capitis lateralis, obliqus capitis superior, obliqus capitis inferior, levator scapulae muscle, splenius cervicis, medial scalene
Transverse Process of C1
Midline bony projections from C2-C7
In the cervical region the spinous process are bifid to accommodate muscle attachments
Spinous process
Longest and most prominent spinous process which is palpable from the skin surface
C7 - VERTEBRAL PROMINENS
Lateral to the spinous process.
This area contains the superior and inferior articular process and facet joints which will be the target for cervical manipulations.
Cervical lamina groove
face superior, posterior, and medially
superior facets
inferior, anterior, and laterally
inferior facets
Located superficially to the trachea on the anterior neck
INFRAHYOID MUSLCES
Antagonist to suprahyoids
Located just to the side of the trachea
sternohyoid
Antagonist to suprahyoids
Located just to the side of the trachea
sternothyroid
Antagonist to suprahyoids
Located just to the side of thyroid cartilage
thyrohyoid
Antagonist to suprahyoids
Most superficial infrahyoid
Runs from the hyoid bone, passing underneath the SCM and scalenes, to the scapula.
Aside from depressing the hyoid, the…. tightens the fascia of the neck and dilates the internal jugular vein
omohyoid
Tucked between the trachea and the anterior cervical vertebrae
Deep cervical flexors
Attaching from the anterior surface of the cervical vertebrae to the occiput and atlas
Laterally flex, rotate, and flex the head and neck
Help to reduce the lordotic curve of the cervical vertebrae
A multi-branched appearance similar to that of the erector spinae muscles.
LONGUS CAPITIS
Tucked between the trachea and the anterior cervical vertebrae
Deep cervical flexors
Attaching from the anterior surface of the cervical vertebrae
Laterally flex, rotate, and flex the neck
Help to reduce the lordotic curve of the cervical vertebrae
A multi-branched appearance similar to that of the erector spinae muscles
LONGUS COLLI
Located on the lateral and anterior aspects of the neck
Contralateral head rotator
It has a large belly with two heads: a flat, clavicular head and a slender, sternal head
Both heads merge to attach behind the ear at the mastoid process.
The carotid artery passes deep and medial to the…..; the external jugular vein lies superficial to it.
SCM
Lies partially tucked beneath the sternocleidomastoid.
Fibers begin at the side of the cervical vertebrae, dive underneath the clavicle and attach to the first rib.
During normal inhalation, elevates the upper ribs
The three …… are sandwiched between the sternocleidomastoid and the anterior flap of the trapezius on the anterior, lateral neck.
the subclavian artery also passes behind
ANTERIOR SCALENE
Slightly larger and lies lateral to the anterior scalene
Fibers begin at the side of the cervical vertebrae, dive underneath the clavicle and attach to the first rib.
During normal inhalation, elevates the upper ribs
MIDDLE SCALENE
Smallest muscle belly, located between the middle scalene and levator scapula. Positioned deeper than the other scalenes
Fibers begin at the side of the cervical vertebrae, dive underneath the clavicle and attach to the second rib.
During normal inhalation, elevates the upper ribs
POSTERIOR SCALENE
carries neurologic information from the cervical spine to the upper extremity.
passes between the anterior and middle scalene
brachial plexus
