(15) One of the characteristics of human masseter muscle is type IM fibers, which are rarely seen in muscles other than the masticatory muscles.
(16) The masseter muscle was always a more efficient producer of vertically oriented bite force than the medial pterygoid.

(20) It was found that the masseter muscle in patients with ZMC fractures developed significantly less force than masseter muscle in controls.
Masseteric
Definition:
(a.) Of or pertaining to the masseter.
Example Sentences:
(1) The anterior temporal muscle SPD was less sensitive to a smaller change of vertical dimension than the masseteric SPD.
(2) We have done this in 3 cases by anastomosing the masseteric nerve to the nearby lower division of the facial nerve.
(3) Graded electrical stimulation was used for orthodromic and antidromic excitation of the masseteric and digastric motoneurones and for orthodromic stimulation of the lingual and inferior alveolar nerves.
(4) It has been demonstrated (Gary Bobo and Bonvallet 1975) that long-lasting stimulation of the "amygdaloid area for the defence reaction" (basal nucleus, pars magnocellularis) elicits, after an initial facilitation, a delayed inhibition of the monosynaptic masseteric reflex (MR), while stimulation of the amygdalofugal fibers running in the ansa lenticularis provokes an immediate inhibition of the reflex.
(5) A patient with Rett's syndrome who demonstrated masseteric hypertrophy, bruxism, and severe attrition is reported.
(6) Within-session (same day) r values ranged from 0.7620 to 0.8884 for the masseteric area and from 0.8686 to 0.9109 for the anterior temporal area.
(7) The duration of masseteric bursts increased during application of the test strip and the chewing rhythm tended to slow down.
(8) 2) Periodontal afferents played an important role in the above facilitatory effect, especially when the masseteric activity was small.
(9) Filaments from the masseteric nerve were stimulated repetitively; muscle fibres belonging to the stimulated motor units were identified by their failure to react for glycogen.
(10) The arteries and masseteric branches which were distributed to the subdivided muscles of the masseter muscle in the rat were as follows.
(11) Direct ultrasonic measurement of masseteric bulk should replace computed tomography as the definitive investigation in suspected cases.
(12) The masticator space is an important suprahyoid tissue compartment bounded by the superficial layer of the deep cervical fascia, enclosing the ramus of the mandible plus the masseteric and pterygoid muscles.
(13) Two ends of the refashioned rib were anchored to masseteric muscle mass and zygoma.
(14) Direct motor responses to stimulation of the masseteric nerve were normal.
(15) The masseteric motoneurones were located laterally in the middle and rostral thirds of the nucleus.
(16) But when the two periods were compared, there was a tendency towards reduction of masseteric area activity and increase of stress levels in the second period of ingestion.
