1

What are the 5 layers of the scalp?

Skin
Connective tissue
Aponeurosis
Loose areolar connective tissue
Pericranium

2

Skin of the scalp

Thick, with hair and sebaceous glands

3

Connective tissue of the scalp

Fibrous, fatty connective tissue with septa that's connect the skin to the aponeurosis

4

Aponeurosis of the scalp

-epicranial
-a thin, tendinous sheet that connects the bellies of the occipitofrontalis

5

Loose aereolar connective tissue of the scalp

Located in the subaponeurotic space

6

Pericranium of the scalp

The periosteum covering the outer surface of the skull bones

7

Infections of the superior Sagittal sinus

Can spread to all the veins of the brain

8

Muscles of the scalp

Occipitofrontalis with 2 bellies
-occipital belly
-frontal belly

9

What muscle originates from the nuchal line of the occipital bone and inserts into the epicranial aponeurosis?

Occipital belly of the occipitofrontalis muscle

10

Occipital belly of the occipitofrontalis muscle of the scalp

Originates from the nuchal line of the occipital bone and inserts into the epicranial aponeurosis

11

What originates from skin and superficial fascia of the eyebrow area and inserts into the epicranial aponeurosis?

The frontal belly of the occipitofrontalis muscle of the scalp

12

Frontal belly of the occipitofrontalis muscle of the scalp

Originates from the skin and superficial fascia of the eyebrow area and inserts into the epicranial aponeurosis

13

What is the action of the occipitofrontalis muscle?

Move the scalp on the skull and raise the eyebrows

14

What is the occipitofrontalis muscle innervated by?

Facial nerve
CN XII

15

What branch does the supratrochlear and supraorbital come from

Branches of the ophthalmic artery

16

Where do the nerves lie in the scalp?

Superficial fascia

17

What is the sensory nerve supply to the scalp?

-supratrochlear nerve
-supraorbital nerve
-zygomaticaotemporal nerve
-auriculotemporal nerve
-lesser occipital nerve
-greater occipital nerve

18

Supratrochlear nerve

-sensory nerve supply to scalp
-branch of the ophthalmic division of the trigeminal nerve (CNV)

19

Supraorbital nerve

-sensory nerve supply to the scalp
-branch of the ophthalmic division of the trigeminal nerve (CNV)

20

Zygomaticotemporal nerve

-sensory supply to the scalp
-a branch of the maxillary division of the trigeminal nerve (CNV)
-cheekbone

21

Auriculotemporal nerve

-sensory innervation to scalp
-branch of the mandible are division of the trigeminal nerve (CNV)

22

Lesser occipital nerve

-sensory innervation of scalp
-branch of the cervical plexus (C2)

23

Greater occipital nerve

-sensory innervation to scalp
Branch of the dorsal ramus of C2

24

Blood supply to scalp

Extensive supply

25

What happens if the scalp gets cut?

Profuse bleeding because of extensive blood supply

26

Arteries of the scalp

-supratrochlear and supraorbital arteries
-superficial temporal artery
-posterior auricular artery
-occipital artery

27

Supratrochlear and supraorbital arteries

-arterial supply of the scalp
-branches of the ophthalmic artery
-ascend over the forehead

28

Superficial temporal artery

-arterial supply of scalp
-terminal branch of the external carotid
-ascends in front of the ear

29

Posterior auricular artery

-arterial supply of the scalp
-branch of the external carotid artery
-ascends behind the ear

30

Occipital artery

-arterial supply of the scalp
-branch of the external carotid artery
-supplies the skin over the back of the skull
