- What types of tissues and structures could be identified
in the raw neck section?
(Skin, muscle, ligaments, tendons, blood vessels, and
- How many vertebrae were found in the neck?
(Since the necks were cleaved at different points, there
will be varying numbers of bones. Most students, however,
should uncover between 14-17 free vertebrae.)
- How are the neck bones adapted to protect the delicate
(They have a central hole within the bone through which
the cord extends. The hard bone material protects this inner
cavity from damage.)
- How are the neck bones adapted to allow flexibility of
the spinal column?
(Since the neck is made up of many bones, it retains
flexibility not found in a solid rod. The bones articulate
with each other but remain in place due to their interlocking
structures and ligament bands.)
- Compare and contrast the role and structure of chicken
and human neck bones. Check out the comparative anatomy
Web site below for more information.
(In both animals, the neck bones work to support and
elevate the head. The neck's flexible nature permits a wide
range of head movements. In addition, the hollow within
the neck bones forms a continuous cavity that protects the
delicate spinal cord. Although the bones in both animals
are hard, the chicken bones are lighter in weight - an adaptation
to aid in flight. In addition, the chicken neck has more
bones than the human neck.)
