D. Lymph nodes

Explanation :

Bone marrow and thymus are primary lymphoid organs

Q.2

The articular cartilage is characterized by all of the following features except :

A. It lacks the capacity to regenerate

B. It has a rich nerve supply

C. It is avascular

D. It is devoid of perichondrium

Explanation :

Articular cartilage has no vessels / nerves.

Q.3

The first costo-chondral joint is a :

A. Synchondrosis

B. Syndesmosis

C. Synovial joint

D. Fibrous joint

Explanation :

Costochondral joints are primary cartilaginous joints / synchondrosis / hyaline cartilage joint.

Q.4

The movement at the following joint permits a person to look towards the right or left :

A. C3-C4 joint

B. C2-C3 joint

C. Atlanto-axial joint

D. Atlanto-occipital joint

Explanation :

Q.5

The intricately and prodigiously looped system of veins and arteries that lie on the surface of the epididymis is known as :

A. Pampiniform plexus

B. Pectiniform septum

C. Tuberal plexus

D. Choroid plexus

Explanation :

The pampiniform plexus is a network of many small veins found in the male spermatic cord. It is formed by the union of multiple spermatic veins from the back of the testis and tributaries from the epididymis.

In addition to its function in venous return from the testes, the pampiniform plexus also plays a role in the temperature regulation of the testes. It acts as a heat exchanger, cooling blood in adjacent arteries. An abnormal enlargement of the pampiniform plexus is a medical condition called varicocele.

Q.6

Infection / inflammation of all of the following causes, enlarged superficial inguinal lymph nodes except :

A. Penile urethra

B. Big toe

C. Inferior part of anal canal

D. Isthmus of uterine tube

Explanation :

Lymphatic drainage of urethra

Penile urethra – deep inguinal lymph nodes
Prostatic urethra and membranous urethra – Internal iliac nodes
Entire female urethra – Internal iliac nodes

Q.7

While exposing the kidney from behind, all of the following nerves are liable to injury except:

A. Iliohypogastric nerve

B. Subcostal nerve

C. Ilioinguinal nerve

D. Lateral cutaneous nerve of thigh

Explanation :

Posterior relations of the kidney:

Diaphragm
Medial and lateral arcuate ligaments
Muscles:

Psoas major
Quadratus lumborum
Transversus abdominis

Subcostal vessels
Nerves:

Subcostal nerve
Iliohypogastric nerve
Ilioinguinal nerve

12th rib (11th rib and 12th ribs in left kidney)

Q.8

An inhaled foreign body is likely to lodge in the right lung due to all of the following features except:

A. Tracheal bifurcation directs the foreign body to the right lung

B. Right principal bronchus is more vertical than the left bronchus

C. Right lung is shorter and wider than left lung

D. Right inferior lobar bronchus is in continuation with the principal bronchus

Explanation :

An foreign body is more likely to get lodged in the right lung as the right bronchus is wider, shorter and more vertical

Q.9

After radical mastectomy there was injury to the long thoracic nerve. The integrity of the nerve can be tested at the bedside by asking the patient to :

A. Raise the arm above the head on the affected side

B. Lift a heavy object from the ground

C. Touch the opposite shoulder

D. Shrug the shoulders

Explanation :

Long thoracic nerve (Nerve of Bell) supplies the serratus anterior muscle
Serratus anterior rotates the inferior angle of scapula laterally during abduction of the arm above the head – hence it is impaired in injury to long thoracic nerve
Winging of scapula is another classical feature of long thoracic nerve injury

Q.10

Barr body is found in the following phase of the cell cycle:

A. Telophase

B. Metaphase

C. G1 phase

D. lnterphase

Explanation :

Q.11

All of the following physiological processes occur during the growth at the epiphyseal plate except:

A. Vasculogenesis and erosion

B. Replacement of red bone marrow with yellow marrow

C. Calcification and ossification

D. Proliferation and hypertrophy

Explanation :

Q.12

The type of joint between the sacrum and the coccyx is a -

A. Syndesmosis

B. Synchondrosis

C. Symphysis

D. Synostosis

Explanation :

Q.13

The following statements concerning chorda tympani nerve are true except that it:

A. Contains postganglionic parasympathetic fibers

B. ls a brach of facial nerve

C. Joins lingual nerve in infratemporal fossa

D. Carries secretomotor fibers to submandibular gland

Explanation :

Chorda tympani nerve contains preganglionic parasympathetic fibers. It synapses in the submandibular ganglion.

Q.14

The superior oblique muscle is supplied by:

A. 4th cranial nerve

B. 6th cranial nerve

C. 5th cranial nerve

D. 3th cranial nerve

Explanation :

Q.15

Paralysis of 3rd, 4th and 6th cranial nerves with involvement of ophthalmic division of trigeminal, localizes the lesion to:

A. Base of skull

B. Cavernous sinus

C. Apex of orbit

D. Brainstem

Explanation :

3,4,5 cranial nerves pass in relation to the lateral wall of cavernous sinus. 6th cranial nerve passes through the cavernous sinus.

Q.16

All of the following are branches of the external carotid artery except:

A. Occipital artery

B. Posterior auricular artery

C. Anterior Ethmoidal artery

D. Superior thyroid artery

Explanation :

Anterior ethmoidal artery arises from ophthalmic branch of internal carotid artery.

Q.17

A. Seminal vesicle when enlarged

B. Prostate

C. Bulb of the penis

D. Internal iliac lymph nodes
