Superficial Face and Scalp Flashcards

1
Q

What are the five layers of the scalp

A

Skin

Dense connective tissue: Holds vasculature and holds them open

Aponeurosis: Connects muscles of facial expression (Occipitofrontalis)

Loose Connective tissue: potential spread of infection due to its potential space

Pericranium

Q

Scalp injuries and the impact on the vasculature

A

Since the vasculature in the head runs from inferior to superior, most of it will be fine for reattachment of the scalp

Q

How does a scalp wound become gaping

A

If the cut penetrates through the aponeurosis it becomes a Gaping wound (due to the pull of the muscles)

Q

Pathway of Parasympathetic motor to lacrimal gland

A

Greater pertrosal nerve arises from CN VII and emerges from the superior surface of petrous part of the temporal bone to enter middle cranial fossa

Greater pretrosal Nerve then joins deep petrosal nerve (Sympathetics) to become nerve of pterygoid canal

nerve of pterygoid canal travels through pterygoid canal and enters pterygopalatine fossa

Parasympathetic fibers then synapse on the pterygopalatine ganglion

then they will innervate the lacrimal gland via the zygomatic branch of V2 and lacramal nerve branch of V1

Q

Visceral parasympathetic motor to submandibular and sublingual glands

A

The chorda tymani branch arises from CN VII just superior to styloid mastoid foramen carrying taste 2/3 of the tongue and GVE

Crosses the tympanic cavity medial to handle of malleus

The chorda tympani passes through the petrotympanic fissure between tympanic and pterous parts of the temporal bone to join lingual nerve V3 in infratemporal fossa

Parasympathetic fibers of chorda tympani synapse in submandibular ganglion and post synaptic fibers follow arteries to glands

18
Q

Bells Palsy

A

Blockage of the Facial Nerve usually occurs ipsilateral side

lose abillity of facial expression

effects eye because patients cant shut their eye
