Cranial bones and Sutures

Question 1

Roof of the nasal cavity. Contains foramina that allow the olfactory nerves (cranial nerve I) to pass from the nose to the brain

Answer 1

cribriform plate

Question 2

Cavity within the bone that is lined with mucosa and open to the exterior. It lightens the skull and alters vocal quality.

Answer 2

Frontal sinus

Question 3

Foramen through which the spinal cord passes to connect with the brain.

Answer 3

Foramen magnum

Question 4

Openings through which the hypoglossal nerves (cranial nerve XII) pass. The hypoglossal nerves carry signals to and from the tongue.

Answer 4

Hypoglossal Canal

Question 5

Articular surface between the occipital bone and the atlas vertebra.

Answer 5

Occipital condyle

Question 6

Opening through which a branch of the trigeminal nerve (cranial nerve V) passes. This branch of the trigeminal nerve carries sensory and motor stimuli to the jaw.

Answer 6

Foramen ovale

Question 7

Opening through which a branch of the trigeminal nerve (cranial nerve V) passes. This branch of the trigeminal nerve carries sensory input from the face.

Answer 7

Foramen rotundum

Question 8

Opening through which blood vessels pass that feed membranes surrounding the CNS

Answer 8

Foramen spinosum

Question 9

Openings through which the optic nerves (cranial nerve II) pass. The optic nerves transmit visual stimuli

Answer 9

Optic canals

Question 10

Structure that holds the pituitary gland

Answer 10

Sella turcica

Question 11

Cavity within the bone that is lined with mucosa and open to the exterior. It lightens the skull and alters vocal quality.

Answer 11

Sphenoid sinus

Question 12

Opening through which the oculomotor, trochlear, trigeminal, and abducens nerves (cranial nerves III, IV, V, and VI) pass. Most of these nerves enable movement of the eyes.

Answer 12

Superior orbital fissure

Question 13

Canal through which the internal carotid arteries pass. The internal carotid arteries supply the majority of the blood to the brain.

Answer 13

Carotid canal

Question 14

Opening through which sound travels on its way to the middle ear.

Answer 14

External acoustic meatus

Question 15

Openings through which the facial and vestibulocochlear nerves (cranial nerves VII and VIII) pass. The facial nerves transmit verve impulses to and from facial muscles and glands, and parts of tongue. The vestibulocochlear verve carries auditory and orientation information to the brain.

Answer 15

Internal acoustic meatus

Question 16

Opening on the occipitomastoid suture through which the internal jugular veins travel as they carry the majority of the blood from the brain back toward the heart. The glossopharyngeal, vagus, and accessory nerves (cranial nerves IX, X, and XI) also pass through the jugular foramen.

Answer 16

Jugular foramen

Articulates with the mandibular condyle of the mandible to form the temporomandibular joint.

Answer 17

Mandibular fossa

Question 18

Attachment point for the sternoceidomastoid muscle of the neck.

Answer 18

Mastoid process

Question 19

Attachment point for several neck and tongue muscles.

Answer 19

Styloid process

Question 20

Opening through which the facial verve (cranial verve VII) passes. The facial nerves transmit nerve impulses to and from the facial muscles, glands, and parts of the tongue.

Answer 20

Stylomastoid foramen

Question 21

Attachment point for the masseter muscle that is important in jaw movement. Articulates with the temporal process of the zygomatic bone to form the zygomatic arch.

Answer 21

Zygomatic process

Question 22

joint between the parietal and frontal bones

Answer 22

coronal

Question 23

joint between the parietal and occipital bones

Answer 23

Lamdoid

Question 24

joint between the parietal bones

Answer 24

Sagittal

Question 25

Joint between the parietal and temporal bones

Answer 25

Squamous

Question 26

Answer 26

Inferiro nasal conchae

Question 27

insertion for the temporalis muscle that is important in elevating the mandible

Answer 27

coronoid process

Question 28

articulates with the mandibular fossa of the temporal bone

Answer 28

mandibular condyle (condylar process)

Question 29

mandibular condyle is also called

condylar process

Question 30

cavity within the bone that is lined with mucosa and open to the exterior. It lightens the skull and alters vocal quality

Answer 30

Maxillary sinus

Question 31

provides an attachment point for muscles associated with the movement of the tongue and with swallowing
