Example: If you purchase $20,000 of marginable stock with a 30% house margin requirement, you would need to initially deposit $10,000, which is the 50% Fed requirement. You would not need to deposit additional money beyond the $10,000 because the house maintenance requirement is below the 50% Fed requirement.
Temporalis. The temporalis is a fan-shaped muscle that covers the side of the head. This muscle closes the jaw, elevates and retracts the mandible, assists in side-to-side movements and maintains the position of the mandible at rest.
It covers the majority of the temporal bone and lesser portions of the frontal and parietal bones. The upper margin of the muscle follows the superior temporal line. Insertion: The temporal muscle inserts on the coronoid process of the mandible.Action: The temporal muscle acts in unison with the masseter and internal pterygoid muscles to close the jaws. Very importantly, it also helps to retrude or pull back the mandible.he depressors of the mandible act to open the lower jaw widely, a function which the muscles of mastication cannot perform. MUSCLES OF MASTICATION There are four paired muscles of mastication. They are the masseters, the temporals, the internal pterygoids, and the external pterygoids.
