What is the ruling on studying and looking at pictures and models of the human body for the purpose of learning, when the husband objects to it claiming it violates the lowering of the gaze?

Using drawings and images in the study of medical sciences is permissible due to general necessity, especially for women to learn medicine to treat other women and preserve their modesty. Women in the era of the Prophet, peace be upon him, practiced medicine and treated the wounded, as stated in authentic hadiths. Spouses should cooperate in this matter, and the wife should consider her husband's jealousy.
