Facet: A facet is part of the facet joint and is made up two superior upward projecting surfaces of the lower
vertebra interconnecting with two inferior downward projecting surfaces from the vertebra directly above. Facet
joints link the bones of the spine together in the posterior or back part of the spine. Two facet joints are present at
each spinal segment. The facet joints are important in controlling twisting, flexion and extension motions of the
cervical and lumbar spine.
Facet Joints: The joints above and below each intervertebral disc, allowing the spine to bend. The paired joints
located on the posterior portion of the vertebral bodies that connect the spine. These joints are responsible for
mechanical stabilization of the spine.
Facet Joint Syndrome: Constant pain resulting from degeneration, wear and tear, and abnormal pressure
exerted on inflamed facet joints.
Facilitative Lesion: When a nerve becomes rubbed, scraped, compressed or stretched due to spinal
malfunction it often becomes irritated and is referred to as a facilitative lesion.
Fascia: Fascia is a layer of fibrous tissue that permeates the human body. This connective tissue surrounds
muscles, groups of muscles, blood vessels, and nerves; it serves binding agent for these structures in much the
same manner as plastic wrap can be used to hold the contents of sandwiches together. It consists of several
layers: a superficial fascia, a deep fascia, and a visceral fascia and extends uninterrupted from the head to the tip
of the toes.
Fat: This is a major source of energy in the diet. Fat also helps the body absorb fat-soluble vitamins, such as
vitamins A, D, E, and K, and carotenoids. Fats can be divided into three categories; monounsaturated,
polyunsaturated, and saturated fatty acids.
Fee For Service: The traditional method of payment for health care services. Payment is made and the service is
then provided by the doctor.
Fibromyalgia: Fibromyalgia is sometimes referred to as fibromyalgia syndrome, formerly known as fibrositis,
and is abbreviated FMS. While fibromyalgia is one of the most common diseases affecting the muscles, its
origin is currently unknown. The condition seems to be rooted in the nervous system which results in the patient
being hypersensitive to external stimuli.
Fibrositis: This condition is now known as fibromyalgia.
Fibrous Joint: Two articular surfaces of bone that come together and are joined by dense irregular connective
tissue that is rich in collagen fibers.
Fixation: Restricted joint movement; inability of a joint to move in its normal range of motion.
Flaccid: Referring to the state of muscles being weak, soft or limp.
Flexion: The motion of bending forward, backward or to the side.
Flexor Muscles: The muscles that cause your joints to bend and contract. Flexion is a position that is made
possible by the joint angle decreasing. The skeletal system and muscles work together to move the joint into a
flexed position. For example the elbow is flexed when the hand is brought closer to the shoulder. The trunk may
be flexed toward the legs or the neck to the chest.
Foramen: Often referred to as foramina. Foramina inside the body typically allow muscles, nerves, arteries,
veins, or other structures to connect one part of the body with another. Foramen can be small or large openings.
Foraminal Stenosis: Foraminal stenosis is a narrowing of the spinal foramen, the hole through which spinal
nerves exits the spine. It is usually a form of degenerative spine disease which occurs slowly over time with wear
and tear of the spinal column.
Frontal: Of, relating to, directed toward, or situated at the front.
Fusion: A post surgical condition where two or more vertebra have been permanently combined with a bone graft
or by way of spinal screws, plates and or bolts. This usually leads to loss of mobility and further wear and tear on
the other spinal structures.
