A
  1. bregma
  2. lambda
19
Q

Which of the cranial fossa is known to be the largest?

A

Posterior Cranial Fossa

20
Q

The following openings in the skull corresponds to its correct bony structure, EXCEPT:

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

A

B. Foramen rotundum - lesser wing of sphenoid

NOTE: This corresponds to the greater wing of sphenoid

21
Q

The following openings in the skull corresponds to its correct bony structure, EXCEPT:

A. hypoglossal canal - occipital bone
B. carotid canal - between petrous part of temporal and sphenoid bone
C. internal acoustic meatus - between petrous part of temporal bone
D. jugular foramen - between petrous part of temporal and condylar part of occipital
E. None

A

E. None

22
Q

The following openings in the skull corresponds to the correct structures it transmits, EXCEPT:

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

A

D. Foramen lacerum = external carotid artery

NOTE: It transmits the INTERNAL carotid artery.

23
Q

The following openings in the skull corresponds to the correct structures it transmits, EXCEPT:

A. Cribriform plate = olfactory nerves
B. Foramen magnum = medulla oblongata
C. Hypoglossal Canal = hypoglossal nerve & spinal part of accessory nerve
D. Jugular Foramen = CN IX-XI
E. None

A

C. Hypoglossal Canal = hypoglossal nerve & spinal part of accessory nerve

NOTE: The spinal part of accessory nerve exits through the foramen magnum

24
Q

TRUE OR FALSE: The epicranial aponeurosis is where the muscle of the scalp is

A

True

25
Q

The occipitofrontalis muscle is innervated by what nerve?

A

CN VII or Facial Nerve

26
Q

The scalp, from anterior to the auricle, is supplied by the (1)______, Then, from posterior to the auricle, it is innervated by the (2)______

A
  1. trigeminal nerve
  2. spinal cutaneous nerve (C2-3)
27
Q

What is known as the “danger area” of the scalp and why?

A

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.

28
Q

What is the most common type of head injury?

A

Laceration

29
Q

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

A

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.

30
Q

This bone is butterfly in shape with a centrally placed body that contains air sinuses

A

Sphenoid bone

31
Q

Which cranial fossa has the most number of opening?

A

Middle Cranial Fossa

32
Q

This bony structure is by which skull articulates with vertebral column

A

Occipital condyle

33
Q

This foramen is for for transmitting the facial nerve and stylomastoid artery.

A

Stylomastoid foramen

34
Q

The coronal suture is formed by the union of the (1)____ and (2)____ bones.

A
  1. frontal
  2. parietal
35
Q

The sagittal suture is formed between what bone?

A

parietal bone

36
Q

It is the thinnest part in the lateral wall of skull

A

pterion

37
Q

This part of the maxilla is a pyramid shape cavity and acts as voice resonator

A

maxillary sinus

38
Q

TRUE OR FALSE: The superior part of the nasal conchae is cartilaginous while its middle and inferior part is bony.

A

False.

 Superior and middle - cartilage
 Inferior - bone

39

A

I - Olfactory
II - Optic
III - Oculomotor
IV - Trochlear
V - Trigeminal (1-3)
VI - Abducens
VII - Facial
VIII - Auditory/Vestibulocochlear
IX - Glossopharyngeal
