NEETMDSThe plateau phase is a sustained depolarization during the action potential, which is a characteristic feature of cardiac muscle cells, including those in the Purkinje fibers, atria, and ventricles. It is caused by the prolonged opening of voltage-gated calcium channels. Among the options provided, Purkinje fibers exhibit this phase.

The most sensitive diagnostic test for hyperparathyroidism is the measurement of serum intact parathyroid hormone (iPTH) levels. Elevated iPTH levels in the context of hypercalcemia are indicative of primary hyperparathyroidism. However, serum calcium levels are also typically high in this condition and are commonly measured in the initial workup.

Hypercalcemia is a common metabolic complication in cancer patients, particularly those with solid tumors such as breast cancer, lung cancer, and multiple myeloma. The most common cause is the secretion of a parathyroid hormone-like protein called PTHrP by the tumor cells.

ProsthodonticsThe Bennet movement is a type of movement that occurs in the temporomandibular joint (TMJ) during the lateral excursion of the mandible, particularly when the mouth is open. It involves the sliding of the articular disk in a lateral direction within the joint space, which allows for the condyle to move smoothly along the articular eminence of the temporal bone. This movement is essential for the normal functioning of the TMJ during activities like chewing and speaking. It is the first type of movement to occur during lateral excursion and is crucial for maintaining the proper alignment of the TMJ components during side-to-side jaw motion.
