Functions of the Vertebral Column

Question 1

What are the functions of the vertebral column?

Answer 1

• protection of the spinal cord, initial PNS and viscera
• support for the head, upper extremities, ribs, viscera, and pelvis
• weight-bearing transfer of torso onto lower extremities
• participates in motion and locomotion
• facilitates shape and position of the torso
• various joints accomplish the concept of resiliency
• transmission of information through intervertebral foramina
• maintains horizontal axis for vision and equilibrium
• stabilizes visceral function via neuronal control

Question 2

How does the vertebral column participate in skeletal formation?

Answer 2

ribs are formed from the costal process of the embryonic vertebral template

Question 3

What levels of the vertebral column specifically accommodate weight-bearing transfer?

Answer 3

S1-S3 at the auricular surface

Question 4

Distinguish between motion and locomotion.

Answer 4

Motion is movement without travel; locomotion is movement to a new site or location

Question 5

What is specifically responsible for shape and position of the human frame?

Answer 5

comparative anterior vs. posterior height of the vertebral body and comparative anterior vs. posterior height of the intervertebral disc

Question 6

How does the vertebral column accommodate transmission?

Answer 6

the peripheral nerve communicates with the central nervous system via the intervertebral foramen

Question 7

What organ(s) is (are) specifically associated with the horizontal axis of the skull?

Answer 7

the eye and the vestibular apparatus of the inner ear

Question 8

How is the vertebral column involved in stabilization of visceral function?

Answer 8

integrity of the spinal column enhances appropriate nerve system control of viscera
