3. Pharynx
The Pharynx
is a funnel
shaped tube
which is
about 12 to
13 cm long.

4. It extends from the posterior nares to
the level of cricoid cartilage.
 The pharynx lies superior to the
larynx (voice box)
 posterior to the nasal and oral
cavities
anterior to the cervical vertebra.

5. the wall of pharynx is made of
skeletal muscle and lined by mucous
membrane
because of the contraction in skeletal
muscle, pharynx assists in deglutition
i.e swallowing.

6. pharynx is divided in 3 portions to
understand its anatomy more wisely. the 3
portions are
1. Naso-pharynx
2. Oropharynx
3. Laryngopharynx.
Pharynx:

8.  is Air passage way
the superior portion of pharynx lies
posterior to nasal cavity reaches till the
soft palate.
contain the pharyngeal tonsils(adenoids)
Auditory Tube opening
Naso-pharynx:

9. Lined by respiratory epithelium
Roof: body of sphenoid and basal
part of occipital bone.
Floor: upper surface of soft Palate
and pharyngeal isthmus.

10. It is the part of the pharynx involved
in respiration.
The lymphatic tissues and adenoids
in the nasopharynx function as part of
the immune system,
Functions of the Nasopharynx

11. The middle portion of pharynx which
extends from the soft palate till the
hyoid bone and lies posterior to oral
cavity.
passageway for air water and food
lingual and palatine tonsils.
Oropharynx:

12. It communicates anteriorly with the oral
cavity by the (oropharyngeal) isthmus
 laterally by the palatoglossal arches, and
inferiorly by the tongue

13. The oropharynx serves both the
respiratory and digestive systems.
It serves as a passageway for food
moving from the mouth to the
esophagus and for air moving to and
from the nasal cavity.
Functions:

14. Hypopharynx.
the inferior portion of pharynx which
begins from the hyoid bone.
At its distal end it opens posteriorly
at esophagus and
 anteriorly in the larynx.
Laryngopharynx:

15. connection point through which food,
water, and air pass.
Specifically, it refers to the point at
which the pharynx divides anteriorly
into the larynx and posteriorly into
the esophagus
