A drug that is used to treat

the digestion of starch and therefore

Unlike the other cranial nerves, most of
the accessory nerve originates from the
spinal cord. The small part of the nerve
that originates from the brain supplies
many muscles of the palate, pharynx
(throat), and larynx (voice box). Damage
to this part of the nerve may cause diffi-
culty in speaking and swallowing. The
spinal part of the nerve supplies large
muscles of the neck and back, notably
the sternomastoid and trapezius. Dam-
age to the spinal fibres of the nerve
paralyses these muscles.
Death that occurs as
a direct result of an accident. A high pro-
portion of deaths in young adults,
particularly among males, are acciden-
tal. Many of these deaths are due to
road traffic accidents, drowning, or drug
overdose. Falls in the home and burning
or asphyxiation due to fire are common
causes of accidental death in elderly
people. Fatal accidents at work have
become less common with the intro-
duction of effective safety measures.
the process by which the eye adjusts
itself to focus on near objects. At rest,
the eye is focused for distant vision,
when its lens is thin and flat. To make
focusing on a nearer object possible,
the ciliary muscle of the eye contracts,
which reduces the pull on the outer rim
of the lens, allowing it to become thicker
and more convex.
With age, the lens loses its elasticity.
This makes accommodation more and
more difficult and results in a form of
