1.
Which of the following conditions is predominant in females?
Correct Answer
C. Congenital hip dislocation
Explanation
Congenital hip dislocation is predominantly found in females. This condition occurs when the hip joint is not properly formed and the femur bone is not securely in the hip socket. It is more common in females due to hormonal and anatomical factors. The condition may be present at birth or develop during the first few months of life. If left untreated, it can lead to hip deformity and difficulty in walking. Early detection and treatment are important to prevent long-term complications.
2.
Following are associated with fibular hemimelia except
Correct Answer
D. Presence of polydactyly
Explanation
Fibular hemimelia is a congenital condition characterized by the absence or underdevelopment of the fibula bone in the leg. It is commonly associated with a short tibia, anterior bowing of the leg, and equinovalgus deformity of the foot and ankle. However, it is not associated with the presence of polydactyly, which refers to having extra fingers or toes. Therefore, the correct answer is "Presence of polydactyly."
3.
Grades of binocular vision are A/E
Correct Answer
D. Suppression
Explanation
Suppression refers to the brain's ability to ignore or suppress the image from one eye when there is a conflict between the two eyes' images. In binocular vision, the brain combines the images from both eyes to create a single, three-dimensional perception of the world. However, in certain cases, such as when there is a significant difference in the images seen by each eye, the brain may suppress or ignore the image from one eye to avoid double vision or confusion. Therefore, suppression is a grade of binocular vision where one eye's image is suppressed to maintain single vision.
4.
Perioral pallor and Dennie's line are seen in
Correct Answer
A. Atopic dermatitis
Explanation
Perioral pallor and Dennie's line are commonly seen in individuals with atopic dermatitis. Atopic dermatitis is a chronic inflammatory skin condition that is characterized by dry, itchy, and inflamed skin. Perioral pallor refers to the pale appearance of the skin around the mouth, which can be a result of chronic inflammation and irritation. Dennie's line is a horizontal crease that can develop below the lower eyelid due to repeated rubbing and scratching of the skin. Both of these findings are frequently observed in individuals with atopic dermatitis due to the chronic nature of the condition and the constant itching and scratching that occurs.
5.
Increased frequency of HLA-B27 is seen in A/E
Correct Answer
D. Myasthenia gravis
6.
Fetal erythropoiesis first occurs at what week of gestation?
Correct Answer
B. 10 weeks
Explanation
Fetal erythropoiesis refers to the production of red blood cells in the fetus. It begins around the 10th week of gestation. At this stage, the fetus has developed the necessary structures, such as the liver and spleen, to start producing its own blood cells. Prior to this, the fetus relies on the mother's red blood cells for oxygen transport. Therefore, 10 weeks is the correct answer as it marks the initiation of fetal erythropoiesis.
7.
The last tributary of the azygos vein is
Correct Answer
C. Right bronchial vein
Explanation
The correct answer is the Right bronchial vein. The azygos vein is a major vein in the body that drains blood from the chest and abdominal walls. It receives blood from various tributaries, and the last tributary before it empties into the superior vena cava is the Right bronchial vein. This vein drains blood from the right lung and bronchial tree, and is an important component of the venous drainage system in the chest.
8.
The superior colliculus is concerned with
Correct Answer
C. Vision
Explanation
The superior colliculus is a structure in the midbrain that plays a crucial role in visual processing. It receives input from the eyes and helps in coordinating eye movements, directing attention towards visual stimuli, and integrating visual information with other sensory inputs. The superior colliculus is involved in various visual functions such as detecting motion, guiding gaze, and orienting the body towards visual targets. Therefore, it can be concluded that the superior colliculus is primarily concerned with vision.
9.
Alpha-fetoprotein is genetically and structurally related to
Correct Answer
A. Albumin
Explanation
Alpha-fetoprotein is genetically and structurally related to albumin. Albumin is a protein produced by the liver and is responsible for maintaining osmotic pressure in the blood, transporting various molecules, and regulating pH levels. Alpha-fetoprotein is also produced by the liver during fetal development and shares similar genetic and structural characteristics with albumin. This similarity suggests that alpha-fetoprotein may have similar functions and properties to albumin, although its exact role is not fully understood.
