What are muscles of mastication? Muscles of mastication are the muscles that are used when you chew on something. It is the process of moving the mandible up and down or side to side. Based on my research the four muscles of mastication are the Masseter Muscle, Temporal Muscle, Medial Pterygoid, and Lateral Pterygoid (Saladin, 2020, p. 238).

Masseter Muscle: The Masseter is the most dominant of the four muscles of mastication. This muscle divides into two parts a superficial head and a deep head (Saladin, 2020, p. 238). The Masseter is located at the very back of your jaw line and goes up just below the cheek bone. The exact insertion would be at the angle of the mandible and superior surface of the ramus (Saladin, 2020, p. 238). The exact origin of the superficial head is at the lower border of the zygomatic bone. The exact location of the deep head is at the lower border of the zygomatic arch (Saladin, 2020, p. 238). The action of the masseter is to elevate and lower the mandible (Saladin, 2020, p. 238).

Temporal Muscle: This muscle is a fan shaped muscle; it is not divided into two parts like the others. The exact origin of this muscle is Temporal Fossa (Saladin, 2020, p. 238). The exact insertion would be in the coronoid process of the mandible (Saladin, 2020, p. 238). The action of the Temporal Muscle is the elevation and retraction of the mandible which closes the mouth (Saladin, 2020, p. 238).

Medial Pterygoid: This muscle also divides into two parts. The exact origin of the superficial head of the Medial Pterygoid is Maxillary tuberosity and pyramidal process of bone (kind of where your wisdom teeth are located) (Saladin, 2020, p. 238). The exact origin of the deep head is the medial surface of lateral pterygoid (Saladin, 2020, p. 238). They both insert into the medial surface of the ramus (Saladin, 2020, p. 238). The action of this muscle is the control over the side-to-side movement of the jaw (Saladin, 2020, p. 238).

Lateral Pterygoid: This muscle has two parts as well. The exact origin of the superficial head would be at the Greater wing of sphenoid bone (Saladin, 2020, p. 238). The deep head is located on the lateral surface of the lateral pterygoid plate (Saladin, 2020, p. 238). The insertion of the lateral pterygoid is at the anterior aspect of the mandibular condyle (Saladin, 2020, p. 238). The action of this muscle is that it depresses the mandible (Saladin, 2020, p. 238).

Critical Thinking

Muscles of mastication are muscles that work together to open and close your mouth. All the movements are the movements of the mandible to chew which is called mastication. You may be wondering what the mandible is? The mandible is your lower jawbone and is the largest bone in the human skull. The maxilla (which is the upper jaw) does not move, therefore the mandible is the only one part that moves. All the four muscles of mastication are connected to the mandible to make it move up and down and side to side.

 

Sample Solution

oted fireman, who plays out his ability consistently and with no particular interest about it. He is an aftereffect of this advancement and, as one would expect, he underrates its characteristics. As the story opens, Montag returns to his country home after one more standard day of book duplicating, just to view as his soul mate, Mildred, barely holding on. She has unexpectedly taken an excess of medication expected to fulfill her, and Montag has barely adequate chance to get helpful help. “They had two machines … One of them slid down your stomach like a dark cobra down a repeating great searching for all the old water and the bygone era accumulated there … ” various channels Mildred absolutely of her hurt blood and replaces it with new enlists. Montag is vivaciously supported by the remedial experts that Mildred’s memory of her self destruction try, if in reality it was one, has been cleaned away. This gathering of events not simply familiarizes the scrutinize with a person compensated for some recent setbacks in an elevating, unsafe break from this present reality, it moreover thus makes Mildred part of a comprehensive arrangement of the state. She is regularly genuinely and sanely connected with some kind of equipment that is apparently emptying the life from her and replacing it with a pointless substitute. In the earlier year there has been such colossal quantities of new and keen advancements made to assist with saving social classes lives. Regardless of the way that, these devices are not “equipment that is apparently emptying the life from her and replacing it with a pointless substitute” these contraption are front line and show that Bradbury had a tendency that new and adroit development was in course Some Machineries/Technologies fuse; Robotic operation; Robotic operation is utilized in unimportantly meddling system and assists with aiding in precision, control and adaptability. During computerized operation, experts can perform extremely complex frameworks that are generally either profoundly troublesome or incredible. Another consolidates, Wireless psyche sensors; Thanks to plastics, therapeutic advances have empowered scientists and experts to work together and create bioresorbable electronics that can be placed in the frontal cortex and separate when they are at absolutely no point in the future required. One more unbelievable development that has been actually made three dimensional printing; If you haven’t heard, three dimensional printers have promptly turned
