Whilst standing beside the patient place your index finger on one of the lumbar vertebral spinous processes, and your middle finger on the next one down and ask the patient to bend over and touch their toes, keeping their legs straight.

Like all cetaceans, the spine of the sperm whale has reduced zygapophysial joints, of which the remnants are modified and are positioned higher on the vertebral dorsal spinous process, hugging it laterally, to prevent extensive lateral bending and facilitate more dorso-ventral bending.
43.
The "'anterior angle "'is divided into two parts a lateral joined to the squamous part by a suture ( petrosquamous ), the remains of which are more or less distinct; a medial, free, which articulates with the spinous process of the sphenoid.
44.
The posterior arch forms about two-fifths of the circumference of the ring : it ends behind in the posterior tubercle, which is the rudiment of a spinous process and gives origin to the " Recti capitis posteriores minores " and the ligamentum nuchae.
45.
When the transverse processes of thoracic vertebrae T10-T12 are pressed or effleuraged with the bottom of the hand, pain can appear at left of spinous processes ( in stomach's lesser curvature ulcer ) or at right ( in pyloric or duodenal ulcer ).
46.
Sometimes the uppermost transverse tubercles are not joined to the rest of the ala on one or both sides, or the sacral canal may be open throughout a considerable part of its length, in consequence of the imperfect development of the laminae and spinous processes.
47.
Posterior divisions : The medial branches ( ramus medialis ) of the posterior branches of the upper six thoracic nerves run between the semispinalis dorsi and multifidus, which they supply; they then pierce the rhomboid and trapezius muscles, and reach the skin by the sides of the spinous processes.
48.
On an anterior oblique radiograph of the lumbar spine, the pars is the neck of the imaginary Scottie dog; the Scottie dog's eye is the pedicle, its hindlegs the spinous process, its nose the transverse process, its ear the superior articular facet and its forelegs the inferior articular facet.
49.
Each muscle is small and somewhat quadrilateral in form; it arises from the superior and posterior part of the transverse process, and is inserted into the lower border and lateral surface of the lamina of the vertebra above, the fibers extending as far as the root of the spinous process.
50.
All dogs ( and all living Canidae ) have a ligament connecting the spinous process of their first thoracic ( or chest ) vertebra to the back of the axis bone ( second cervical or neck bone ), which supports the weight of the head without active muscle exertion, thus saving energy.
