what are the four main functions of the human spine?

Answer 1

I am assuming you mean the spinal cord rather than the vertebral bodies. In that case:

Modulation of reflex arcs
Afferent signal pathways (taking information to the brain)
Efferent signal pathways (sending signals from brain to the body)
Autonomic control and regulation

Answer 2

Bone Composition
Bone Structure
The bone has five main functions:

1. Support
That's about everything just covered above
2. Protection
They keep organs away from damage, such as the rib cage and the skull.
3. Movement
That's covered above, also.
4. Storage
The bone stores fat and some minerals.
5. Blood cell formation
The bone is the place that most of your blood components are made.

Answer 3

Lets see here, some functions of the vertebral column are to protect the spinal cord, provide skeletal support for the rest of your body, provide a place for skeletal muscles to adhere and cant think of anything else. If you wanted to know the evolutionary advantages of having a spinal cord I don't remember those.

Answer 4

1. Protection of the spinal cord
2. Support the weight of the body
3. Provide attachment point for soft tissues
4. Support the rib cage

Answer 5

1) Structural support
2) Protection (of the spinal cord and nerve roots)
3) Movement
4) Synthesis of blood cells

Answer 6

The spine: its role in protection, anchoring, and weight bearing >

Answer 7

1. Hold the body up
2. Support the body
3. send messages from the brain
3. Protect the organs (back of them)... I think

Answer 8

supporting the torso
acts as a channel for nervous tissue and blood vessels
is a shock absorber

Answer 9

keep u upright
obviously connectd to ur brain
coordinates movement
something to do with nerves
also our spines are most developed arent they?!
I wonder why!?
but u shud luk this up in a textbuk!
gud question!

Answer 10

One function is that it keeps your nose well away from your bum.
