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.
Movements at this joint are produced by the muscles of mastication, and the hyoid muscles. The two divisions of the temporomandibular joint have different functions. Protrusion and Retraction. The upper part of the joint allows protrusion and retraction of the mandible â the anterior and posterior movements of the jaw. The lateral pterygoid muscle is responsible for protrusion (assisted by the medial pterygoid), and the geniohyoid and digastric muscles perform retraction. Elevation and Depression.
