Q- Which nerve passes through the marked area in the given image?

           A. Lingual nerve

           B. Mandibular nerve

           C. Chorda tympani 

           D. Inferior alveolar nerve

Answer is B. Mandibular nerve

Marked area is Mandibular foramen.

Mandibular foramen is the opening on the medial surface of the ramus:passageway for the inferior alveolar nerve and artery, which supply to the lower teeth. 

Q- Boundary of triangle of auscultation is not formed by:

         A. Serratus anterior

         B. Scapula

         C. Trapezius

         D. Latissimus dorsi

Answer is A. Serratus anterior 

The triangle of auscultation is a small triangular space on the back where the relatively thin musculature allows for respiratory sounds to be heard more clearly with a stethoscope.

It has the following boundaries:

🔹medially, by the Trapezius

🔹laterally by the scapula

🔹inferiorly by the Latissimus dorsi

The floor is formed by

🔹7th rib

🔹6th & 7th intercostal spaces

🔹Rhomboideus major

On the left side, the cardiac orifice of the stomach lies deep to the triangle, and in days before X-rays were discovered the sounds of swallowed liquids were auscultated over this triangle.

Q- At which joint does inversion of the foot occur:

           A. Talocrural

           B. Talocalcaneal

           C. Calcaneocuboid

           D. Cuneonavicular

Answer is B.  Talocalcaneal

▪️Inversion: The medial border of the foot is raised so that sole faces inside.

▪️Eversion: The lateral border of the foot is raised so that the sole faces outside.

▪️Inversion and eversion occur mainly at the subtalar joint.
