Exam 2: Cervical Flashcards
how many joints does the cervical spine consist of
37, which allow for more motion than any other region of the spne
when you increase mobility
you decrease stability (more vulnerable to both direct and indirect trauma)
a complete examination of the cervical spine requires
that the patient unless to the waist exposing the neck area as well as the entire upper extremeity
what do surgical scars on the anterior portion of the neck most often indicate
previous thyroid surgery
what do irregular, pitted scars in the anterior triangle could be
previous tuberculous adenitis
what articulations is each pair of vertebrae in the cervicals connected by
a pair of zygzapophyseal joints
uncovertebral joints
IVD
the structure of the cervcial vertebrae combined with orientation of the zygapophyseal facets provide
very little bony stability
the lax soft tissue restraints permit
large excursions or motions
what kind of curve is in the cervical spine
lordotic curve that develops secondary to the response of an upright posture, which initially occurs when the child begins to lift the head at 3-4 months
what does the presence of the curve allow
allows the head and eyes to remain oriented forward, and provides a shock absorbing mechanism to counteract the axial compressive force produced by the weight of the head (how many pounds?)
where is the weight of the head
directly above the center of gravity
what happens in forward head translation
if the head is 3 inches in front of the COG an estimated 30 pounds of weight is produced in structures of the c-spine
what is palpation performed
- check for any vasomotor changes such as an increase in skin temperature
- localize specific sites of swelling
- identify specific anatomical structures and their relationship to one another
- identify sites of point tenderness
- indentify soft tissue texture changes or myofascial restriction
- locate changes in muscle tone resulting from, trigger points, muscle spasm, hypertonicity, or hypotonicity
where is the hyoid bone located
opposite of C3
where is the thyroid cartilage located
“adams apple” level of the C4/C5 vertebral body
where is the first cricoid ring located
opposite C6 vertebral body
