Kepler noticed that most planets have highly elliptical orbits planetary motion that caused him to propose Kepler's first law of orbital motion
<u>Explanation:</u>
- Kepler described that planets revolving around the sun in an elliptical orbit. Thus it also improved the Nicolaus heliocentric theory.
- He found the elliptical orbit of all planets by calculating the orbit of the mars. He totally proposes the three laws as such newton which are considered to be essential in the calculation of the orbit shape distance and other factors in the space.
- Kepler's planetary motion law conveys that planets has sun as the one of the foci while it moves in the elliptical orbit .
The two muscles of mastication that that are involved in closing of the mandible are the masseter and pterygoid muscles.
Actually, three muscles that work together are involved in movement of the mandible: Temporalis, Masseter and Pterygoid Muscles.
Temporalis muscle - assists in closing the mouth and moving the mouth from side to side during the chewing.
Masseter muscle- the main chewing muscle and one of the strongest muscles in the body.
Pterygoid muscles- with the Masseter muscle to assist in the chewing action and jaw rotation.
