Red arrow:

What is the point:

Green arrow:

Pink:

yellow:

Red circle = zygomatic arch

Red arrow: zygomaticus major

What is the point: moteolus (central spot where a bunch of muscles for facial expression/elevators and depressors meet)

Green arrow: risorius

yellow: levator anguli oris

green, red, purple, orange, blue, and zygomatic is where

Temporal (green),

sphenoid (red),

occipital (purple),

parietal (orange),

frontal (blue),

zygomatic (in front of red)

what is this

foramen magnum

crest: crysta galli

around: cribiform plate

what are these suture lines

Sagittal (left side)

Coronal (Front)

Thing sticking out: hyoid bone

Jaw bone: mandible

A little in front of the mandible (no arrow): body

Back of mandible: angle

“Top stem” of mandible: ramus

Pointy thing that is high: styloid process

Behind the styloid process: mastoid process

Muscle: mylohyoid muscle

what are these holes

L → R

supraorbital foramen

infraorbital foramen

what muscle

semispinalis muscle

what muscle

splenius muscle

left arrow

right arrow

What is the tiny branch artery

left arrow: internal carotid

right arrow: superior thyroid branch (external carotid)

tiny branch a: thyroid a → thyrocervical trunk

Muscle far behind the black, red, yellow, green arrows:

Muscle right behind black/red/yellow/green arrows: s

Green arrow:

Yellow circle:

Red arrow:

White arrow:

Orange arrow:

Blue circle:

Muscle next to pink arrow:

Black arrow:

Muscle to the right of the digastric muscle that joins:

Together if you keep going to the right =

Pink arrow:

Bulb under the facial artery:

Muscle far behind the black, red, yellow, green arrows: splenius (wide and wraps around)

Muscle right behind black/red/yellow/green arrows: scalene muscles

Green arrow: common carotid arter

Yellow circle: carotid sinus

Red arrow: internal carotid artery

White arrow: external carotid

Orange arrow: superior thyroid a

Blue circle: thyroid gland

Muscle next to pink arrow: masseter muscle

Black arrow: posterior belly of digastric muscle

Muscle to the right of the digastric muscle that joins: stylohyoid muscle

Together if you keep going to the right = Anterior belly of digastric muscles

Pink arrow: facial artery

Bulb under the facial artery: submandibular gland

Middle upper muscle:

Bulbous looking thing:

Artery between them:

Middle upper muscle: masster muscle (if you contract masster muscle, you feel facial artery)

Bulbous looking thing: submandibular gland

Artery between them: facial artery

Red arrow:

Yellow:

Pink:

Bottom bone:

White arrow:

Red arrow: myohyoid (deeper) [image is posterior]

Yellow: posterior belly digastric

Pink: anterior belly

Bottom bone: hyoid

White arrow: styloid process

Black: t

The hole near the black arrow will eventually lead to: foramen magnum, but before that, under that layer =

Yellow:

Red:

Black: tentorium cerebelli

The hole near the black arrow will eventually lead to: foramen magnum, but before that, under that layer = cerebellum

Yellow: crysta galli

Red: falx cerebri

Red =

Yellow =

Exit point:

Red = facial nerve

Yellow = vestibulocochlear nerve

Exit point: internal acoustic meatus

exit point around the tip of the 2 white arrows (the sapce):

Below the hole:

Other white arrow:

Exit point/hole:

yellow arrow:

the nerves through the hole:

red:

exit point around the tip of the 2 white arrows (the space): foramen magnum

Remember: above is brainstem (you can see the medulla “triangle” and the pons is above that)

Below the hole = cervical spinal cord

Other white arrow: accessory nerve (coming off near spinal cord from cervical region)

Exit point: jugular foramen

Which means the 3 nerves (yellow) near the hole: accessory, glossopharyngeal, vagus nerve

Yellow arrow: vagus nerve

red? = glossopharyngeal?

White circle:

Red arrow:

Orange:

Black arrow:

pink:

White circle: where parotid gland is (superficial), if tucked in would be deep

Red arrow: sternocleidomastoid

Orange: anterior digastric muscle

Black arrow: buccinator muscle

pink: masseter

black:

Yellow:

Nerves comes through:

Green arrow:

White arrow:

Yellow:

Artery on top of masseter:

Red:

A little in front of that muscle =

black: parotid gland

Nerves comes through: facial nerve

Green arrow: parotid duct (piercing the buccinator muscle)

White arrow: buccinator muscle

Yellow: masseter muscle

Artery on top of masseter: facial artery

Red: zygomatic arch

A little in front of that muscle = zygomaticus major (has to have involvement of zygomatic arch)

Red circle =

Red arrow:

What is the central point of muscles:

Green arrow:

Pink:

yellow:

Red circle = zygomatic arch
