A progressive disease that causes rigid muscles tremors and pill-rolling is

Correct Answer: B

Rationale: The correct answer is B: Parkinson's disease. This neurodegenerative disorder is characterized by rigid muscles, tremors (especially at rest), and the distinctive pill-rolling movement of the fingers. Epilepsy (A) is a neurological disorder with recurrent seizures. Meniere's disease (C) affects the inner ear, causing vertigo and hearing loss. Dementia (D) refers to a decline in cognitive function.

Correct Answer: C

Rationale: Turning downward is also called pronation. This movement involves rotating a body part downward or inward. In anatomical terms, pronation refers to the inward rotation of the forearm or foot. Supination (A) is the opposite movement of pronation, involving outward rotation. Hyperextension (B) is the excessive extension of a joint beyond its normal range of motion. Extension (D) refers to straightening or unbending a joint. Therefore, the correct answer is C, as it specifically describes the action of turning downward.

Correct Answer: B

Rationale: The correct answer is B: Algor mortis. Algor mortis refers to the cooling of the body after death.

Rigor mortis (A) is the stiffening of muscles after death, Livor mortis (C) is the pooling of blood in the dependent parts of the body, and Algae mortis (D) is not a recognized term in forensic science. Thus, the correct term for the cooling of the body after death is Algor mortis.
