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.
They are one of the major muscle groups in the head â the other being the muscles of facial expression. There are four muscles of mastication â the masseter, temporalis, medial pterygoid and lateral pterygoid. Embryologically, the muscles of mastication develop from the first pharyngeal arch.Consequently they are innervated by a branch of the trigeminal nerve (CN V), the mandibular nerve.he entirety of the muscle lies superficially to the pterygoids and temporalis, covering them. 1  Attachments: The superficial part originates from maxillary process of the zygomatic bone. 2  Actions: Elevates the mandible, closing the mouth. 3  Innervation: Mandibular nerve (V 3).
