Two factors that permit flexability of the vertebral column?

Answer 1

The presence of the discs and the S-shaped or springlike construction of the vertebral column prevent shock to the head in walking and running and provide flexibility to the body trunk.

Answer 2

The presence of the discs and the fact that ther verterbral column is in an S shape permit flexibility of the vertebral column.

- The sacrum and the coccyx are connected in such a way as to provide a flexible curved structure ( pg 133 Marieb&mitchell)

Answer 3

the vertebral column AKA the spine consists of spinal segments (vertebrae) which are joined by:

1. facet joints- which allow the spine to bend forward/back/side, etc.

2. inter-vertebral disks: fluid filled disks which absorb shock and prevent damage to the spinal segments from physical activity

The presence of the discs and the fact that the verterbral column is in an S shape permit flexibility of the vertebral column.

Answer 4

The two factors that permit the flexibility of the vertebral column are: a.)Intervertebral discs contain a large amount of water which act like rubber

b.) the vertebral column curvatures.

Answer 5

Intervertebral disk and vertebral column curvatures.

Answer 6

Fibrous ring (annulus fibrosus) of intervertebral discs and cerebral spinal fluid.
