Compiled by:

Reference Books:

  • Langman Medical Embryology 14th Edition

Note:

  • Do both CVS and Respiratory System from Langman.
  • Make flow charts for all developments.
  • Don’t stick to every single line.

AXIAL SKELETON

Chapter 10:

(Re-A-015 – Re-A-016)

  • Do Vertebrae and Vertebral Column (Very Important SEQ), Must do Its Diagram Along as well.
  • Anomalies mentioned of Vertebral defects (Do Complete)
  • Do Ribs and Sternum (Important SEQ as well) Along with their Anomalies
  • For axial Skeleton overview: From sthe start of chapter, Just Go through once as it is not linked to Your Syllabus but mentioned in LOs, you just have to know basic overview of Axial skeleton and factors contributing.
  • Regarding anomalies of Axial Skeleton, you have to do those, as they were asked from us in Proff 2024, you can’t skip Anomalies.

Chapter 7:

(Re-A-017)

  • Diaphragm and thoracic cavity (Do it completely till the End of Chapter)
  • Sources of Diaphragm is a repeatedly asked question. Do it Conceptually and Thoroughly. (Proff 2023 Question)
  • Must do Anomalies of Diaphragm Like Diaphragmatic Hernia etc (Important)

CARDIOVASCULAR SYSTEM

Chapter 13:

(CV-A-004 – CV-A-010)

This chapter is tricky to Understand, for this firstly take Ninja Nerd Lecture to Grasp the Concept properly and then readout the textbook thoroughly. Otherwise, you will not be able to retain it.

  • Do all the developments from establishment and patterning of primary heart field semilunar valves. These are often asked in SEQ and OSVE as well. Must Do all these through lectures (Otherwise it will be difficult to Understand)
  • Most Important Among these are:
    • Cardiac Loop formation
    • Septum formation in the common atrium (Proff Viva Question)
    • Formation of left atrium and pulmonary Vein
    • Septum formation in the atrioventricular Canal
    • Septum formation in the truncus arteriosus and Conus Cordis (Proff Question)
  • You must have to do all as well, anyone of them might come.
  • Must do All the clinicals In between. (Important as well)
  • Formation of Conducting system of heart, Do it thoroughly
  • Table 13.1 Not important (Just Go through for MCQs, to remember event Duration)
  • Must do derivatives of aortic arches only table 13.2 (Important to Do)
  • Vascular System: Arterial System (Changes that occur with alteration in aortic arch system) Very Important SEQ.
  • Course of Recurrent Laryngeal Nerve is an important SEQ
  • Rest of arteries: vitelline, Umbilical Coronary Do Understand it atleast, They are often asked at VIVA stations and MCQs
  • Clinicals of arterial System are very Important
  • Venous System: Do Understand Coronary, Vitelline, umblical and Cardinal Veins for Viva and MCQs.
  • Development of IVC Important SEQ
  • Clinicals of venous system Must to do
  • The rest of the Chapter is not Important. Regarding the Lymphatic system. It never Came till now. But to be on the safe side. At least, you must have a concept of it.

Most Important Clinicals:

  • Dextrocardia
  • Tetralogy of Fallot
  • Patent ductus arteriosus
  • Unequal division of arterial trunks
  • Transposition of great
  • Vessels and Valvular stenosis
  • Coarctation of aorta

Note: These are most important clinicals but you have to do all the clinicals because mostly SEQs are asked from clinicals.

RESPIRATORY SYSTEM

Chapter 14:

(Re-A-018 – 019)

Note: Do watch Ninja Nerd Lecture for it as well before Reading. It is a very Easy Chapter.

  • Formation of lung bud
  • Larynx, Trachea, bronchi & Lungs (Do All by Ninja Nerd Lecture)
  • Maturation of lungs make a flow chart (not as such important)
  • Table 14.1 maturation of lungs, must do week duration as well, You have to write it properly (Proff 2024 Question + Block 3 Internal Question)

Clinicals:

  • Esophageal atresia (Repeatedly Asked SEQ, Viva Question)
  • VECTERL (Do Read it Out for MCQs)
  • Respiratory distress syndrome (v.v imp)

Note: As I Always Mention, After Doing Any Chapter of Embryology, Do Go through the Question written at the End of Each chapter. In Proff Exams, Exact These statements are Asked in SEQ Questions, you can check out Proff Question paper of 2023. Repeatedly asked in Blocks. So, you must have to go Through these Questions at the End. Answer key of these Questions is given at the End of Book Langman.
