Identifying Anatomy

Question 1

identify EJV

Answer 1

large vein, crosses SCM

Question 2

identify submandibular gland

Answer 2

spherical glandular tissue, medial side of mandible, walnut shaped

Question 3

identify superior thyroid artery

Answer 3

goes into the top of the thyroid

Question 4

identify recurrent laryngeal nerve

Answer 4

comes out of the bottom of the thyroid

Question 5

identify the orbicularis oculi

Answer 5

muscle above eye with orbital part superior to palpebral part. general function is closure of eyelid.
orbital = scrunching of eye
palpebral = blinking

Question 6

identify parotid duct

Answer 6

small duct coming out of parotid gland aka Stensen’s duct. saliva goes from parotid to mouth via here

Question 7

identify the maxillary artery

Answer 7

branches off the ECA, may also see superficial temporal artery going straight up but maxillary artery goes more mesially

Question 8

identify the lingual nerve

Answer 8

nerve going behind the mandible, chorda tympani associated also, submandibular ganglion may be seen on the lingual nerve too (very thin branch)

Question 9

identify corpus callosum

Answer 9

bit that joins the two hemispheres of the brain and will be joining the two or present on only one half

Question 10

identify the basilar artery

Answer 10

large artery which runs down midline of brainstem area

Question 11

identify styloglossus

Answer 11

connects styloid process to the tongue and arches down

Question 12

identify hyoglossus

Answer 12

muscle straight up and down, below tongue, under styloglossus

Question 13

identify medial pterygoid

Answer 13

below lateral pterygoid

Question 14

identify submandibular duct

Answer 14

large duct that extends forwards out of submandibular gland aka Wharton’s duct

Question 15

identify greater auricular nerve

Answer 15

crosses SCM upwards mesially

Question 16

identify SCM

Answer 16

easily identifiable, large muscle in the neck that splits the anterior and posterior triangles

Question 17

identify the stylohyoid muscle

Answer 17

muscle attaches to hyoid bone, splits around central tendon of posterior belly of digastric and becomes tendon; this is quite visible and if it doesn’t split it crosses at the central tendon

Question 18

identify the mylohyoid muscle

Answer 18

makes up the floor of the mouth, under the anterior & posterior belly of digastric

Question 19

identify the auditory tube

Answer 19

opening surrounded by tubal tonsil which connects nasopharynx to middle ear aka eustachian tube / pharyngotympanic tube

Question 20

identify the palatoglossal fold

Answer 20

anteriormost fold seen in the mouth that is in front of the palatine tonsil

Question 21

identify the vocal folds

Answer 21

folds of tissue, either side of the laryngeal ventricle, deep to cricoid cartilage

Question 22

identify the cricoid cartilage

Answer 22

immediately below the cricothyroid ligament, above this is the thyroid cartilage

Question 23

identify the posterior belly of digastric

Answer 23

should see the central tendon connection to anterior belly coming from the chin, stylohyoid crosses at central tendon

Question 24

identify the hypoglossal nerve

Answer 24

runs underneath the posterior belly of digastric so this may need to be removed / reflected to see this

Question 25

identify the infraorbital nerve

Answer 25

may be seen in the orbit or above the sinus

Question 26

identify the greater palatine nerve

Answer 26

runs along the underside of the maxilla
