Ans: B. Interossei and lumbricals
Hyperextension of metacarpophalangeal joint and flexion of the
interphalangeal joint is due to palsy of lumbricals and interossei
muscles.
The action of Lumbricals: Flexion of MCP, Extension of IP joint
The action of Palmar interossei: Adduction of fingers
The action of Dorsal interossei: Abduction of fingers

Ans:C. Gartner's cyst.
Gartner's cysts, sometimes incorrectly referred to as vaginal inclusion cysts, are the most common benign cystic lesions of the vagina. They represent embryological remnants of the caudal end of the mesonephric( Wolffian) duct. Gartner's ducts are found in about 25% of adult women. Almost one percent of these ducts evolve into Gartner's duct cyst. Ref: A case of Gartner's cyst of vagina, J. Anesth Crit care Open Access, 2017, 00259.

Answer- A. Mesonephros
The ureteric bud, also known as the metanephrogenic
diverticulum, is a protrusion from the mesonephric duct during the
development of the urinary and reproductive organs.
It later develops into a conduit (channel) for urine drainage from the
kidneys, which, in contrast, originate from the metanephric
blastema.
The metanephrogenic blastema or metanephric blastema (or
metanephric mesenchyme, or metanephric mesoderm) is one of the
two embryological structures that give rise to the kidney, the other
being ureteric bud.
Correct Answer -A Answer- A. Lateral medullary syndrome The posterior inferior cerebellar artery (PICA), the largest branch of the vertebral artery, is one of the three main arterial blood supplies for the cerebellum, part of the brain. Occlusion of the posterior inferior cerebellar artery or one of its branches, or of the vertebral artery leads to lateral medullary syndrome also called Wallenberg syndrome

Correct Answer - B Ans: B. Pretracheal fascia The thyroid gland is covered by a thin fibrous capsule, which has an inner and an outer layer. The inner layer extrudes into the gland and forms the septum that divides the thyroid tissue into microscopic lobules. The outer layer is continuous with the pretracheal fascia, attaching the gland to the cricoid and thyroid cartilages via a thickening of the fascia to form the posterior suspensory ligament of the thyroid gland also known as Berry's ligament. This causes the thyroid to move up and down with the movement of these cartilages when swallowing occurs. Gray's Anatomy: The Anatomical Basis of Clinical Practice, 41e ,Page no 470
