A cervical rib in humans is an extra rib which arises from the seventh cervical vertebra. Their presence is a congenital abnormality located above the normal first rib. A cervical rib is estimated to occur in 0.2% [6] to 0.5% [7] (1 in 200 to 500) of the population. [8] People may have a cervical rib on the right, left or both sides. [9] [10]

The anterior scalene muscle (Latin: scalenus anterior), lies deeply at the side of the neck, behind the sternocleidomastoid muscle.It arises from the anterior tubercles of the transverse processes of the third, fourth, fifth, and sixth cervical vertebrae, and descending, almost vertically, is inserted by a narrow, flat tendon into the scalene tubercle on the inner border of the first rib, and ...
This rudimentary rib causes fibrous changes around the brachial plexus nerves, inducing compression and causing the symptoms and signs of TOS. This is called a "cervical rib" because of its attachment to C-7 (the seventh cervical vertebra), and its surgical removal is almost always recommended. The symptoms of TOS can first appear in the early ...
An accessory muscle can also refer to a muscle that is not primarily responsible for movement but does provide assistance. [1] Examples of such muscles are the accessory muscles of respiration where the sternocleidomastoid and the scalene muscles (anterior, middle and posterior scalene) are typically considered accessory muscles of respiration.

Passive accessory intervertebral movements (PAIVM) refers to a spinal physical therapy assessment and treatment technique developed by Geoff Maitland. The purpose of PAIVM is to assess the amount and quality of movement at various intervertebral levels, and to treat pain and stiffness of the cervical and lumbar spine .
Similar to the inflatable cervical traction devices on this list, this neck and back cervical spine hydrator from Posture Pump, provides support to the cervical spine, according to Hansraj.
In birds, ribs are present as distinct bones only on the thoracic region, although small fused ribs are present on the cervical vertebrae. The thoracic ribs of birds possess a wide projection to the rear; this uncinate process is an attachment for the shoulder muscles. [9] Usually dogs have 26 ribs. Mammals usually also only have distinct ribs ...
