Q

masseter

A

O: superficial part - maxillary process of zygomatic bone. Deep part - zygomatic arch of the temporal bone

I: both attach to the ramus of the mandible

A: elevates the mandible, closing the mouth

N: mandibular nerve

23
Q

temporalis

A

O: temporal fossa

I: condenses into a tendon, inserts onto the coronoid process of the mandible

A: elevates the mandible, closing the mouth. Retracts mandible, pulling the jaw posteriorly.

N: mandibular nerve

24
Q

medial pterygoid

A

O: superficial head - maxillary tuberosity, pyramidal process of palatine bone. deep head - medial aspect of the lateral pterygoid plate of the sphenoid bone.

I: ramus of the mandible near the angle of mandible

A: elevates the mandible, closing the mouth

N: mandibular nerve

25
Q

lateral pterygoid

A

O: superior head - greater wing of the sphenoid. inferior head - lateral pterygoid plate of the sphenoid

I: converge into a tendon, attaches to the neck of the mandible

A: bilat, protract the mandible. unilateral - side to side movement of the jaw (contraction on one side will cause lateral movement on the contralateral side, ex. contract left = move mandible to the right).

N: mandibular nerve

26
Q

extrinsic muscles of tongue

A
  • genioglossus
  • hyoglossus
  • styloglossus

A

only attach to other structures in the tongue.

  • superior longitudinal
  • inferior longitudinal
  • transverse
  • vertical
28
Q

auricular

A

O: anterior - galea aponeurotica anterior to ear. superior- galea aponeurotica superior to ear. posterior - mastoid process

I: auricle

A: wiggle the ears

N: anterior and superior - temporal branches of fascial nerve (VII). Posterior - posterior auricular branch of fascial nerve (VII)

29
Q

chondroglossus

A

O: medial nside of the lesser horn and body of the hyoid bone

I: ascends to blend with the intrinsic tongue musculature

A: pulls the sides of the tongue down

N: hypoglossal nerve (XII)

30
Q

cilliary

A

O: meridional fibres- scleral spur. Circular fibres - encircle the ciliary process

I: meridonal fibres- ciliary process. Circular fibres- encircle the ciliary process

A: relaxes the suspensory ligament of the lens

31
Q

digastric

A

O: anterior belly- digastric fossa of the mandible. Posterior belly - mastoid notch of the temporal bone

I: body of the hyoid via a fibrous loop over an intermediate tendon

A: elevates the hyoid bone, depresses the mandible

N: anterior belly - mylohyoid nerve, from the mandibular division of the trigeminal nerve (V). posterior belly - fascial nerve (VII)

32
Q

O: frontalis - galea aponeurotica. occipitalis- superior nuchal line

I: frontalis - skin of the eyebrows. occipitalis - galea aponeurotica

A: elevates the eyebrows and wrinkles the forehead

N: frontalis - temporal branches of the facial nerve (VII). occipitalis - posterior auricular branch of the facial nerve (VII).

34
Q
