73] Lymphatic drainage of face
The face possesses three areas from which lymphatic drainage
is as follows:?
1. Upper area, comparising greater part of forehead, lateral Vi of
eyelids, conjunctiva, lateral part of cheek and parotid area, drains
into preauricular (superficial) parotid nodes.
2. Middle area, comprising central part of forehead, external nose,
upper lip, lateral part of lower lip, medial halves of eyelids, medial
part of cheek, and greater part of lower jaw, drains into
submandibular nodes.
3. Lower area, including central part of lower lip and the chin, drains
into submental nodes.

Correct Answer - A

Ans. A. Greater omentum
The portion of the dorsal mesentery that attaches to the greater curvature of the stomach, is known as the dorsal mesogastrium. The
part of the dorsal mesentery that suspends the colon is termed the
mesocolon. The dorsal mesogastrium develops into the greater omentum.

Correct Answer - B
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

Correct Answer - A
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 the ureteric bud.

Boundaries of cubital fossa-
Laterally - Medial border of brachioradialis.
Medially - Lateral border of pronator teres.
Base - It is directed upwards, and is represented by an imaginary
line joining the front of two epicondyles of the humerus.
Apex - It is directed downwards, and is formed by the area where
brachioradialis crosses the pronator teres muscle.
