B. Foramen rotundum - lesser wing of sphenoid
C. Foramen ovale - greater wing of sphenoid
D. Foramen spinosum - greater wing of sphenoid
E. None
B. Foramen rotundum - lesser wing of sphenoid

C. internal acoustic meatus - between petrous part of temporal bone
D. jugular foramen - between petrous part of temporal and condylar part of occipital

A. Foramen rotundum = CN V-2
B. Foramen oval = CN V-3 & lesser petrossal nerve
C. Foramen spinosum = middle meningeal artery
D. Foramen lacerum = external carotid artery
E. None
D. Foramen lacerum = external carotid artery
NOTE: It transmits the INTERNAL carotid artery.
The following openings in the skull corresponds to the correct structures it transmits, EXCEPT:

B. Foramen magnum = medulla oblongata
C. Hypoglossal Canal = hypoglossal nerve & spinal part of accessory nerve
D. Jugular Foramen = CN IX-XI
E. None
C. Hypoglossal Canal = hypoglossal nerve & spinal part of accessory nerve
NOTE: The spinal part of accessory nerve exits through the foramen magnum
TRUE OR FALSE: The epicranial aponeurosis is where the muscle of the scalp is
True
The occipitofrontalis muscle is innervated by what nerve?
CN VII or Facial Nerve
The scalp, from anterior to the auricle, is supplied by the (1)______, Then, from posterior to the auricle, it is innervated by the (2)______
- trigeminal nerve
- spinal cutaneous nerve (C2-3)
What is known as the “danger area” of the scalp and why?
Loose connective tissue layer
Reason: pus or blood spreads easily in it. thus, infection in the areas may pass through the emissary veins and enter the cranial cavity.
What is the most common type of head injury?
Laceration
TOPIC: Layers of the Scalp
Determine which statement is INCORRECT:
A. Loose areolar connective tissue allows movement of the scalp proper over the underlying calvaria
B. Aponeurosis is a thin and weak tendinous sheet that covers the calvaria
C. Pericranium is a dense layer of connective tissue that forms the external periosteum of the calvaria
D. The skin of the scalp has abundant arterial supply and good venous and lymphatic drainage
E. The layer of connective tissue is a thick, dense, richly vascularized subcutaneous layer
B. Aponeurosis is a thin and weak tendinous sheet that covers the calvaria
The Aponeurosis is a strong sheet and contains the muscle of the scalp.
