1

Layers of Scalp

Hair and skin
Sub Q tissue
Galea Aponeurotica: tendon expansion
Loose connective tissue
Periosteum: covers surface of bone

2

Auditory Ossicles

Function in hearing. Located three on each side of the head deep within the cavities of the temporal bone

3

Cranial Vault

Eight bones that encase and protect the brain:
Parietal, temporal, frontal, occipital, sphenoid, ethmoid bones

4

Formane Magnum

Brain connects to the spinal cord through a large opening at the base of the skull

5

Sutures

How the skull bones are connected

6

Fontanelles

Soft in infants and link the sutures together

7

Mastoid Process

Base of each temporal bone and is cone shaped

8

Crista Galli

Prominent bony ridge in the center of the anterior fossa and is point of attachment for meninges

9

Ciribriform Plate

Surrounds Crista Galli with numerous openings allowing the passage of olfactory Nerve filaments from nasal cavity

10

Olfactory Nerves

Cranial Nerves for smell, send projections through the foramina in the ciribriform plate and into nasal cavity

11

Zygomatic Arch

Bone that extends along the front of the skull below the orbit

12

Brain

Occupies 80% of cranial vault and contains billions of neurons

13

Major regions

Cerebellum, diencephelon, brainstem, and cerebellum

14

Brain cont

See neurological emergencies

15

Frontal Lobe

Voluntary motor actions and emotion

16

Parietal Lobe

Somatic or voluntary sensory and motor functions, memory and emotions

17

Occipital

Optic Nerve originates, responsible for visual information.
Injury to the back of the head mya see stars because the optic Nerve banged against the back of the skull

18

Temporal Lobe

Speech center

19

Limbic System

Influences motivation, emotions, motivation, mood, and sensations of pain and pleasure

20

Meninges

Protective layer that surround and enfold the entire CNS

21

Dura Mater

Outside Strong, fibrous layer wrapping brain

22

Arachnoid

Second layer, delicate transparent membrane

23

Pai Mater

Third Layer, translucent highly vascular membrane

24

CSF

Manufactured in the ventricles of the brain

25

Subarachnoid Space

CSF flows in this space. Located between the pia and arachnoid matters.

26

CSF Manufactured

Manufactured by cells within the choroid plexus in the ventricles, hollow storage areas in the brain

27

Vertebral Body

Anterior weight bearing structure is made of bone that provides support and stability

28

Components of Vertebrae

Spinous Process, Pericles, lamina

29

Pedicle

Inside of spinous process

30

Lamina

Groove of branch of spinous process
