Brain
The brain have five lobes: frontal lobe, parietal
lobe, temporal lobe and occipital lobe
The cerebral hemispheres form the largest
part of the human brain and are situated
above most other brain structures.

Underneath the cerebrum lies the brainstem,
resembling a stalk on which the cerebrum is
attached.
At the rear of the brain, beneath the cerebrum
and behind the brainstem, is the cerebellum

Ears
Our ears have three different sections that
work together to collect sounds and relay
them to the brain:
Outer Ear
The part of the ear that is visible is called
pinna, this includes earlobe. It's made of
tough cartilage covered by skin.

The ear canal, the hollow passage that leads
to your eardrum, is also part of the outer ear.
Glands in the skin lining your ear canal
produce earwax.

Middle ear
The middle ear is an air-filled cavity about the
size of a pea. Is separated from the outer ear
by tympanic membrane. This thin, cone-
shaped piece of tissue stretches tight across
the ear canal.

The reason your ears are able to adjust and
maintain equal pressure is because the
Eustachian tube. This tube connects your
middle ear to the back of your nose and acts
as a sort of pressure valve, opening to keep
the pressure equalized on both sides of the
eardrum.

It's in the middle ear that you'll find the three smallestbones in the body. Located just past the eardrum,they're collectively known as the ossicles:
the malleus (Latin for "hammer"), which is attached tothe eardrum
the incus ("anvil"), which is attached to the malleus
the stapes ("stirrup"), which is attached to the incusand is the smallest bone in the body

Inner ear
The inner ear consists of tiny organs called the
cochlea and the semicircular canals.
The semicircular canals look like three tiny,
interconnected tubes sticking out in loops
from the top of the cochlea. The canals are
filled with fluid and lined with tiny hairs.

Eyes
The eyeball is about the size and shape of a
ping-pong ball.
The eyeball sits in the orbit in skull, where it is
surrounded by bone. The visible part of the
eye is protected by the eyelids and the
eyelashes, which keep dirt, dust, and even
harmful bright light out of the eye.
-

Our eyes are also protected by our tears,
which moisten the eyes and clean out dirt,
dust, and other irritants that get past the
defenses of our eyelashes and eyelids.

Every time we blink, our eyelids spread a layer
of moisture over the cornea, which covers the
front of the eye. The lacrimal glands in the
upper outer corner of each eye socket
produce tears.
-

After they've done their job moistening the
eyes, the tears flow into canals in the eyelids,
which drain into the lacrimal sac, a pouch in
the lower inner corner of each eye socket.
Tears then exit through a passage that leads to
the nose.

Six muscles, called extraocular muscles,surround the eyeball in the skull. These
muscles act like the strings on a puppet,
moving the eye in different directions.

The wall of a person's eyeball is made up of three
layers:
The sclera is the outermost protective layer. This
tough, fibrous tissue surrounds the eyeball and
attaches to the cornea. The conjunctiva a clear
mucous membrane that protects the eye frombecoming dry, sits over the sclera and also covers
the inner surface of the eyelid.

The choroid is the middle layer that contains
blood vessels that deliver oxygen and
nutrients to the inside parts of the eye.

The retina, the innermost of the three layers,
lines the inside of the eyeball. The retina is a
soft, light-sensitive layer of nervous system
tissue.

The space in the center of the eyeball is filled
with a clear jelly-like material called the
vitreous humor.

Mouth
The mouth is lined with mucous membranes.
Just as skin lines and protects the outside of
the body, mucous membranes line and protect
the inside.

A bundle of muscles extends from the floor of
the mouth to form the tongue. The upper
surface of the tongue is covered with tiny
projections called papillae. Our taste buds arelocated here. The four main types of taste
buds: sweet, salty, sour, and bitter.

floor of the mouth secrete saliva.

The lips are covered with skin on the outside
and with slippery mucous membranes on the
inside of the mouth. The major lip muscle,
called the orbicularis oris , allows for the lipsmobility.

Pharynx
The pharynx is the part of the throat situated
immediately posterior to the mouth and nasal
cavity, and superior to the esophagus and
larynx.

The pharynx is conventionally divided into
three sections:T
Nasopharynx (epipharynx)
Oropharynx (mesopharynx)
laryngopharynx (hypopharynx)

The pharynx is part of the digestive system
and also the respiratory system; it is also
important in vocalization.

Larynx
The larynx, commonly called the voice box, is
an organ in the neck involved in breathing,
sound production, and protecting the trachea
against food aspiration. The larynx houses thevocal folds, which are essential for phonation.

The laryngeal skeleton consists of nine
cartilages:
Three single (epiglottic, thyroid and cricoid)
Three paired (arytenoid, corniculate, and
cuneiform)
