this will be tested on thursday

2. • The spinal cord is a
long, thin, tubular bundle
of nervous tissue and
support cells that extends
from the brain.

3. • Serves as a conduit for motor
information, which travels down
the spinal cord.
• Serves as a conduit for sensory
information, which travels up the
spinal cord.
• Serves as a center for
coordinating certain reflexes.

4.  The spinal cord is basically
the "information highway of
the body", messages are sent
back and forth between the
brain and the rest of the
body. This information
includes touch, temperature,
pain, joint position and signals
telling muscles to move.

6. •1.)Cervical- the main function of
the cervical spine is to support
the weight of the head (about 10
pounds).
•2.)Thoracic- The main function of
the thoracic spine is to protect
the organs of the chest by
providing attachment for the rib

7.  3.) Lumbar- The main function of
the lumbar spine is to bear the
weight of the body.
 4.) Sacral- The main function of
the sacrum is to provide
attachment for the iliac (hip)
bones and protect the pelvic
organs.

8.  • 5.) Coccyx- the four fused bones
of the coccyx or tailbone don’t
really have a function. It is an
embryology remnant of a tail from
our primate ancestors.

9.  The spinal cord can be damaged in many
ways, producing various symptoms,
depending on the location, or level, of
spinal cord damage. The spinal cord can
be cut in an accident, compressed,
destroyed by infection, damaged when
its blood supply is cut off, or affected
by diseases (such as spinal cord cysts,
cervical spondylosis, or multiple
sclerosis) that alter its nerve function.
