Q1 · Embryology
EasyExplanation
Each pharyngeal arch keeps its own nerve however far its muscles migrate. Arch one takes V3 and gives the muscles of mastication, mylohyoid, the anterior belly of digastric, tensor tympani and tensor veli palatini. Arch two takes the facial nerve, arch three the glossopharyngeal, and arches four and six the vagus.
Q2 · Embryology
EasyExplanation
Stapedius is a second arch muscle and is therefore supplied by the facial nerve, the nerve of that arch. This is why facial nerve palsy proximal to the nerve to stapedius produces hyperacusis, since the muscle can no longer damp stapes movement. Tensor tympani, by contrast, is a first arch muscle supplied by V3.
Q3 · Embryology
MediumExplanation
Arch four is supplied by the superior laryngeal branch of the vagus and arch six by the recurrent laryngeal branch. All the intrinsic laryngeal muscles except cricothyroid derive from arch six and are therefore recurrent laryngeal territory. Cricothyroid is the arch four exception, supplied by the external branch of the superior laryngeal nerve.
Q4 · Embryology
EasyExplanation
Meckel diverticulum is the persistent proximal part of the vitellointestinal duct, which normally obliterates in the seventh week. It is a true diverticulum containing all bowel layers, arises from the antimesenteric border of the ileum, and may contain ectopic gastric or pancreatic tissue. The ectopic gastric mucosa is what causes painless bleeding in children.
Q5 · Embryology
EasyExplanation
The ductus arteriosus connects the pulmonary trunk to the aortic arch in fetal life and closes functionally within hours of birth, leaving the ligamentum arteriosum. The left recurrent laryngeal nerve hooks under this ligament, which explains its long course in the chest. The umbilical vein becomes the ligamentum teres and the ductus venosus becomes the ligamentum venosum.
Q6 · Embryology
MediumExplanation
The notochord regresses in the vertebral bodies but persists between them as the nucleus pulposus, the only adult remnant of the structure. The surrounding anulus fibrosus and the vertebral bodies themselves come from sclerotome. Chordoma, a tumour of notochordal remnants, arises for the same reason at the sacrococcygeal and clival ends of the axis.
Embryology sits within Anatomy, which carries the same syllabus in both exams. This set runs to 6 questions, each tagged Easy, Medium or Hard.
Answer first, then read the explanation even on the ones you got right — the reasoning is where Embryology marks are actually won, and it is what separates a recalled fact from a question you can solve in a new form. Once the Easy set feels comfortable, filter to Hard to find the gaps Anatomy examiners keep returning to.
FAQ
Yes. Every question and explanation in this Embryology set is free and open — no login, no form and no payment. The explanation appears the moment you answer.
Embryology sits within Anatomy, which appears in the same form in both syllabuses. Gross anatomy, neuroanatomy, embryology and histology, the four areas NEET PG returns to every year. Nerve injuries, foramina and blood supply carry most of the marks.
