how many face bones do we have
22
cranium
Bones that protect the brain
Upper cranium
Calvaria
What does calvaria contain
Frontal bone
Parietal bone
Occipital bone
Temporal bone
What does the occipital bone give passage to
medulla oblongata
Function of medulla oblongata
Connects brain to the spinal cord
Foramen magnum
opening in the
occipital bone through which the
brain and spinal cord connect
What is a suture
A suture is a fibrous joint
found only in the skull. The
parietal bones (in blue) come
together to form the sagittal
suture and also form the
coronal suture with the
frontal bone.
Coronal - line from ear to ear
Sagittal - line from coronal down the middle
sphenoid bone
The sphenoid is a bat-shaped bone
and is the keystone bone at the
base of the cranium. It is not part of the cranium but protects the underside of the brain
Ethmoid bone
The ethmoid is a spongy, cubed bone that gives shape
to part of the roof of the nose and the orbits. The ethmoid is also home to
numerous foramina through
which the branches of the
olfactory nerves pass
SQUARE BEHIND NOSE
What is the only freely moveable part of the face
The mandible
articulates with the temporal
bones at the temporomandibular
joint.
Name of upper jaw
The maxillae form the
upper jaw and the boundary
of three cavities:
* the roof of the mouth
* the floor and lateral wall of
the nasal cavity
* the floors of the orbits.
what bones form cheek bones
zygomatic
Bridge of nose
nasal bone and attached to nasal cartilage
Sides of inner eye
The lacrimal bones (inside
the orbits) contain the lacrimal
sacs that continue as the
nasolacrimal ducts, or tear
ducts.
The nasal and lacrimal bones are
some of the smallest bones to
make up the facial bones
Nasal septum
volmer bone, very thin. The superior half of the vomer is fused
with the perpendicular plate of the
ethmoid, and its lower half attaches to
the septal cartilage.
The posterior border is free and
separates the choanae, also known
as the internal nares.
pointy bones coming down diagonally from nose
nasal conche. The nasal conchae
consist of a layer of spongy
bone curled up on itself like
a scroll.
The medial surface of the
conchae are perforated for the
passage of numerous vessels.
The folds of the conchae
increase the surface area
of the nasal cavities. This
enhances the warming and
humidifying air passing over
them.
where is palatine bone
back of nasal cavity. The posterior borders of the
palatines serves as the attachment
site of the soft palate, and the sharp
medial borders form the posterior
nasal spine for the attachment of the
uvula.
temporalis muscle (muscle for mastification)
Large fan shape on the side of the head
Origin: Inferior temporal line
Insertion: apex process of mandible
forms a tendon that goes through the temporal fossa (hole near zygomatic)
medial pterygoid muscle for mastification
point of jaw to cheekbone
origin: Medial surface of lateral pterygoid plate of sphenoid bone
insertion: Medial surface of ramus and angle of mandible
