Anatomic clinical correlations: final lecture in anat. lab Flashcards
SCALP:
-S=
Skin – very vascular – loss of heat
SCALP:
C=
Dense Connective Tissue – Contains arteries and veins and nerves
SCALP:
A=
Aponeurotic Layer – Galea Aponeurotica – dense fibrous tissue that goes from the Frontalis muscle to the Occipitalis muscle (Occipitofrontalis muscle) –these muscles move scalp, wrinkle forehead, and raise eyebrows. Innervated by the Facial Nerve – Frontalis by the Temporal branches and the Occipital by the Posterior Auricular branches (Latter not part of “To Zanzibar by Motor Car”).
SCALP:
L=
Loose connective tissue – where scalp moves – infections spread here.
SCALP:
P=
Periosteum – fixed to the bony calvarium
SCALP:
-first 3 layers are tightly held together forming a _____
*unit – scalp proper- what is “scalped”
SCALP:
The skin and dense CT are very _____
vascular and the latter tends to keep vessels open, they do not retract, so there is a great deal of bleeding.
Layers of the scalp from superficial to deep:
- skin
- dense CT
- Aponeurotic layer
- Loose connective tissue
- Pericranium
Ovarian cancers are characterized by:
- most of them are LATE stage when you find them (they grow silently)
- sister mary joseph sign
Vascularity to the Scalp is from the ______
- Internal Carotid Artery:
- -Opthalmic artery > Supratrochlear a and Supraorbital a
- External Carotid Artery >
- -Superficial Temoral a, Posterior Auricular a, and Occipital a.
***Veins follow arteries
Scalp - Innervation:
Sensory innervation= dividing line is _____
the ears and vertex
Scalp - Innervation:
-Cranial nerves are located ______
anterior to the dividing line
Scalp - Innervation:
-which nerve innervates the following: Supratrochlear, Supraorbital, Zygomaticotemporal, and Auriculotemporal nn
Trigeminal N=CNV *****
Scalp - Innervation:
Cervical Nerves are located ______ to the dividing line
posterior
___ = “Sleep Area” – Greater auricular n, Greater and Lesser _______ nerves
- *C2
- Occipital nerves**
