24
Q

Digastric Muscle

Study These Flashcards
A

Origin: the posterior belly is the mastoid process and the anterior belly is the digastric fossa of the mandible
Insertion: both go to the intermediate tendon of the digastric
Action: elevate the hyoid bone
Innervated: posterior belly is CN 7 while anterior is CN 5

25
Stylohyoid
Origin is the styloid process Insertion is the body of the hyoid bone Action is to elevate the hyoid bone Innervated by CN 7
26
Mylohyoid
Origin is the mylohyoid line of the mandible Insertion is the body of the hyoid bone Action is to elevate the mandible Innervated by C1 hypoglossal
27
Cricothyroid
Origin is the anteriolateral circoid cartilage Insertion is the inferior thyroid cartilage Action is to tenses and elongate the vocal cords
28
Internal carotid artery runs through what?
Stylohyoid, Digastric, and the mandible
29
Branches of Carotid Artery
Superior Thyroid Artery Ascending Pharyngeal artery Lingual Artery Facial Artery Occipital Artery Posterior Auricular Artery Maxillary Artery
30
How does the superior thyroid artery move?
descends anteriorly to supply the upper thyroid gland.
31
How does the ascending pharyngeal artery move?
ascends posteriorly to supply pharynx
32
How does lingual artery move?
It is at the level of hyoid bone, and runs behind suprahyoid to supply tongue
33
Where and how does the occipital artery move?
It is at the hyoid bone, and runs superior and posterior. Found deep to posterior belly of digastric
34
Where does the posterior Auricular Artery?
It ascends posteriorly between external acoustic meatus and mastoid process.
35
How does the maxillary artery move?
It moves deep to the mandible and supplies deep structures of the face
36
How does the superficial temporal artery move?
It moves superiorly and over zygomatic arch
37
Where does the subclavian artery arise from?
Brachiocephalic trunk on right and aortic arch on left
38
What is the danger space?
The posterior retropharyngeal space
39
Anterior Retropharyngeal space
It is between the buccopharyngeal and alar fascia, helps spread infection
40
The Retropharyngeal space

43
Anterior (alar) Prevertebral fascia
smaller of the two fascial planes
44
Prevertebral Fascia is what?
Three parts, anterior posterior and axillary sheath. Invests vertebral column and muscles
45
Carotid Sheath is
Contains the internal and common carotid arteries, internal jugular veins, vagus nerves. Formed from three facial layers investing pretracheal prevertebral
