DO (True or False) 4

Question 1

Preganglionic sympathetic fibers supplying the heart originate from spinal cord levels T1–T4.

Accepted Answer

True

Answer

Preganglionic cardiac sympathetic fibers arise from T1–T4, synapsing in the cervical and upper thoracic sympathetic ganglia before innervating the heart.

Question 2

According to Fryette's Law I, sidebending and rotation in a neutral spine occur to opposite sides.

Accepted Answer

True

Answer

Fryette's Law I states that in a neutral (non-flexed, non-extended) spine, sidebending and rotation couple to opposite sides and involve a group of vertebrae.

Question 3

Type II somatic dysfunction (Fryette's Law II) describes a single vertebral segment where sidebending and rotation occur to the same side.

Accepted Answer

True

Answer

Fryette's Law II applies to a single non-neutral (flexed or extended) vertebral segment in which sidebending and rotation couple to the same side.

Question 4

The greater splanchnic nerve (T5–T9) carries preganglionic fibers to the celiac ganglion.

Accepted Answer

True

Answer

The greater splanchnic nerve (T5–T9) provides preganglionic sympathetic fibers to the celiac ganglion, which innervates the upper abdominal organs.

Question 5

Loss of cervical lordosis on lateral cervical X-ray always indicates serious pathology requiring immediate intervention.

Accepted Answer

False — it is a common finding with muscle spasm, positioning, or poor posture

Answer

Loss of cervical lordosis is frequently a benign finding associated with muscle spasm, patient positioning during imaging, or habitual posture and does not mandate urgent intervention.
