Week 1 - Muscles of Head and Neck Flashcards
What are the muscles of the head and face that we cover
temporalis
masseter
Pterygoids
Occipitofrontalis
Orbicularis oculi
Orbicularis oris
TEMPORALIS:
origin:
Insertion:
Action:
Innervation:
Temporal bone
coronoid process and ramus of the mandible
elevation of the mandible
trigeminal nerve
This muscle may be problematic for those who clench their has in response to stress
temporalis and masseter
what artery is superficial to the temporals and its pulse may be palpated
superficial temporal artery
MASSETER
Origin:
Insertion:
Action:
Innervation:
the zygomatic and temporal bones of the zygomatic arch
the ramus and angle of the mandible
elev of mandible
Trigeminal nerve
What gland and structure are superficial to the masseter
parotid gland and duct
both pterygoids are innervated by
trigeminal nerve
insertion of the medial pterygoid?
the medial surface of the ramus of themandible
movement of the medial and lateral pterygoids?
movement of the mandible
OCCIPITALIS
Origin:
Insertion:
Action:
Innervation:
occipital bone
galea aponeurotica
elevation of eyebrows
facial nerve
FRONTALIS
Origin:
Insertion:
Action:
Innervation:
galea aponeurotica
fascia/skin above eye and nose
elev. eyebrows
facial nerve
galea aponeurosis
a broad, flat tendon uniting the muscle fibers the frontal and occipitalis
action and innervation of ORBICULARIS OCULI
closes the eyes
facial nerve
action and innervation of ORBICULARIS ORIS
closes the lips
facial nerve
muscles nearest to the superficial temporal artery
masseter
temporalis
muscles nearest to the facial artery
orbicularis oculi and orbiculares oris
the large parotid salivary gland and duct would be superficial to the
masseter and the insertion of the temporalis
the submandibular glad is located
on the inner surface of the mandible
several superficial ___ ____ are located near some of the muscles we covered such as the masseter and temporalis
lymph nodes
