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.
Breathing consists of two phases, inspiration and expiration. During inspiration, the diaphragm and the intercostal muscles contract. The diaphragm moves downwards increasing the volume of the thoracic (chest) cavity, and the intercostal muscles pull the ribs up expanding the rib cage and further increasing this volume. This increase of volume lowers the air pressure in the alveoli to below atmospheric pressure.
