Scalp Flashcards
What are the five layers of the Scalp?
Skin, Connective tissue, Aponeurosis (epicranial), Loose areolar tissue, and Pericranium
These layers are intimately bounded together and move as a unit
Skin, connective tissue and aponeurosis
Thick and hair bearing which also contains numerous sebaceous glands
Skin
Located beneath the skin which is fibrofatty
Connective tissue
The fibrous septa uniting the skin to the underlying aponeurosis of what muscle
Occipitofrontalis muscle
What arteries are found in the connective tissue layer of the scalp?
Branches of the external and internal carotid artery
A thin, tendinous sheet that unites the occipital and frontal bellies the occipitofrontalis muscle.
Aponeurosis (epicranial)
The lateral margins of the aponeurosis are attached to what?
Temporal fascia
This occupies the subaponeurotic space and loosely connects the epicranial aponeurosis to the periosteum of the skull
Loose areolar tissue
The areolar tissue contains what important veins?
Emissary veins
These are valveless that connect the superficial veins of the scalp with the diploic veins of the skull bones and with what venous sinuse?
Emissary veins; intracranial venous sinuses
This is the periosteum covering of the outer surface of the skull bones
Pericranium
What can raise the eyebrows?
The frontal bellies of the occipitofrontalis
This nerve is a branch of the ophthalmic division of the trigeminal nerve that winds around the superior orbital margin and supplies the scalp
Supratrochlear nerve
What passes backward close to the median plane and reaches nearly as far as the vertex of the skull?
Supratrochlear nerve
A branch of the ophthalmic division of the trigeminal nerve that winds around the superior orbital margin and ascends over the forehead
Supraorbital nerve
The supraorbital nerve supplies the?
Scalp as far backward as the vertex
The zygomaticotemporal nerve is a branch of ___ which supplies the scalp over the temple
Maxillary division of the trigeminal nerve
A branch of the mandibular division of the trigeminal nerve that ascends over the side of the head from in from of the auricle.
Auriculotemporal nerve
The terminal branches of the auriculotemporal nerve supply what?
Skin over the temporal region
This supplies the scalp over the lateral part of the occipital region, the skin over the medial surface of the auricle and is a branch of the cervical plexus (C2)
Lesser occipital nerve
a branch of the posterior ramus of the 2nd cervical nerve, ascends over the back of the scalp and supplies the skin as far forward as the vertex of the skull
Greater occipital nerve
