serves to
• Protect against injury
• Protect against SUN UV rays
• Prevent entry of harmful microorganism
• Maintain the internal body temperature
• Excrete waste materials through
perspiration
• Function as a sense organ

5. EPIDERMIS

DERMIS
• Nerves, vessels, glands,
hair follicles

8. EAR

10. AURICLE/ PINNA
• Made of elastic
cartilage
• Helix rim
• Lobule (ear
lobe)
EXTERNAL
AUDITORY
CANAL
• Lies within
temporal bone
and connects to
ear drum
• Contents
ceruminous
glands which
secrete ear wax
TIMPANIC
MEMBRANE
• Epihelial and
simple cuboideal
• Changes
acoustic energy
into mechanical
energy
THE EXTERNAL
EAR

11. AUDITORY OSSICLES
• Malleus – attached to
ear drum, articulates
with incus
• Incus - articulates
with stapes
• Stapes – footplate of
stapes fits into oval
window
AUDITORY
(EUSTACHIAN) TUBE
• Is a route for
pathogens to travel
from nose and throat
to ear causing OTITIS
MEDIA
• During swallowing
and yawning it opens
to equal pressure in
middle ear
THE MIDDLE EAR

12. THE INNER EAR
• Auditory liquids : vibration travel through this liquid
• Organ of Corti : sensitive auditory receptor, are tiny
hair like
COCHLEA
Leads from the oval
window, small, snail
shaped, has 2 parts
• Receive sound vibrations from the auditory liquids
and end in the auditory center of the cerebral cortex
AUDITORY NERVE
FIBERS
• Connect the cochlea to 3 semicircular canals for
balance

It is spherical in shape
It is about 2,5 cm in diameter
Situated in the orbital cavity

29. A
 “White of the eye”
 Dense fibrous connective tissue
 Contains blood vessels and insertion site for extrinsic eye muscle

30. A
 Thin transporting epitelium
 Continuos with the sclera, covering iris and pupil

31. IRIS
 “Color part of the eye”
 Creates and adjust the pupil
 Contains blood vessels, pigment cells, loose connective
tissue and pupillary muscle
 Regulates amounts of light

32. LENS
 Focuses image on the retina
 Closely packed concentric columnar cells

33. BODY
 Ring of smooth muscle around lens
 Regulates the shape of the lens for accomodation

34. LIGAMENTS
 Attach the ciliary body to the lens

35. RETINA
 Lines the posterior part of the eye
 Held in place by the vitreous
 Contains light-sensitive photoreceptors

36. CHOROID
 Pigmented to absorp excess light
 Supplies the retina with nutrients and oxygen via blood
supply
