💀ANATOMY 💀 ● Pharyngeal pouches/Arches: ➢ 1st pouch - Tongue ➢ 2nd pouch - Tonsil ➢ 3rd pouch - Thymus, Inferior parathyroid gland ➢ 4th pouch - Superior parathyroid gland ➔ 1st arch - Mandibular nerve, Maxillary artery, Meckel's cartilage, Mastication muscles ➔ 2nd arch - Seventh nerve, Stapedial artery, Stapes, Stapedius, and Stylohyoid muscle and Posterior belly of digastric. ➔ 3rd arch - 9th nerve and anterior belly of digastric ➔ 4th arch - Cricothyroid muscle and Superior laryngeal nerve. ➔ 6th arch - Recurrent laryngeal nerve ● Ureter develops from Mesonephric duct ● Gartner’s cyst arises from remnant of Mesonephric duct ● Excretory portion of kidney is formed by: Mesonephric duct ● Lower 1/3rd of vagina is developed from Sinovaginal bulb. ● Vestibule of the vagina develops from Urogenital sinus. ● Appendix of testis is derived from Paramesonephric duct. ● Spermatogenesis begins at - birth Use code INDIAN for maximum discount on every subscription ● Development of sperm from spermatogenesis takes - 70-75 days. ● Sperm acquire motility in Epididymis. ● Primary oocyte is formed after Mitotic division. ● First polar body is formed after first meiosis. ● Persistent primitive streak leads to - Sacrococcygeal teratoma. ● Umbilical vein becomes Ligamentum teres. ● The supporting cells of the testis are - Sertoli cells. ● Implantation occurs after 7-9 days after Ovulation. ● Intrinsic laryngeal muscles are supplied by Recurrent laryngeal nerve. ● Taste sensation of anterior 2/3rd of tongue are carried by facial nerve. ● Skin over angle of mandible is supplied by C2/C3. ● Subcutaneous tissue is the vascular layer of the scalp. ● Position of the Thyroid isthmus is C6-C7 level. ● Tensor of the vocal cord is - Cricothyroid. ● Closure of neural tube begins at Cervical end. ● Posterior communicating artery is a branch of the Middle cerebral artery. ● The chorda tympani nerve arises from the facial nerve. ● Taste fibres are relayed in tractus solitarius. ● Broca’s area is located in inferior frontal gyrus. ● Ophthalmic artery is a branch of - Intracranial internal carotid artery. ● Protractor of scapula is Serratus anterior. ● Winging of scapula is due to injury to nerve to serratus anterior. ● Lower angle of scapula lies at the level of T7. ● Lateral border of cubital fossa is bounded by the Brachioradialis ● Porter’s tip deformity is seen in Erb’s paralysis. ● Erb’s point is C5-C6. ● Klumpke’s paralysis involves C8/T1. ● First bone to ossify in the body is Clavicle. ● Wrist drop is seen in the damage of radial nerve.
