Which of the following movements are unique to the foot?

Correct Answer: C

Rationale: Foot movements include dorsiflexion (toes up) and inversion (sole inward), unique to its anatomy. 'Dorsiflexion and inversion,' is correct, per kinesiology (e.g., Neumann). 'Elevation and depression,' applies to shoulders. 'Abduction and adduction,' is general. 'Opposition and reposition,' is thumb-specific. Foot-specific terms make C the accurate answer.

Correct Answer: C

Rationale: Spermatogenesis is the full process of sperm formation, from spermatogonia to mature spermatozoa. 'Spermatogenesis,' is correct, per histology texts like Junqueira's Basic Histology, encompassing mitosis, meiosis, and differentiation. 'Oogenesis,' is egg formation. 'Spermiogenesis,' is the final differentiation phase, not the whole process. 'Spermatogonia,' are precursor cells, not the process. Spermatogenesis' comprehensive scope makes C the precise answer, covering all stages.

Correct Answer: C

Rationale: Fat-soluble vitamins dissolve in lipids, stored in body fat. 'Vitamin C,' is correct as the exception, being water-soluble, excreted in urine, per nutrition texts (e.g., Gropper). 'Vitamin A,' 'Vitamin D,' and 'Vitamin K,' are fat-soluble, absorbed with dietary fats. Vitamin C's hydrophilic nature, vital for collagen, distinguishes C as the accurate answer.

Correct Answer: D

Rationale: The large intestine includes caecum, colon, rectum, and anal canal. 'Duodenum,' is correct as the exception, part of the small intestine, per anatomy (e.g., Moore). 'Caecum,' begins the large intestine. 'Colon,' is its main segment. 'Rectum,' stores feces. Duodenum's small intestinal role distinguishes D as the accurate answer.
