Embryology Mnemonic Flashcards
Derivation of ocular tissue - neuroectoderm
Use the mnemonic (If PROVEN) CLEVER, SEE TV i. Neuroectoderm: Iris sphincter/dilator, Pigmented iris epi, RPE, Optic nerve, axons and glia, Vitreous, Epithelium of ciliary body, Neurosensory retina
Derivation of ocular tissue - surface ectoderm
Use the mnemonic If PROVEN (CLEVER), SEE TV
ii. Surface Ectoderm:
Conj & K epithelium,
Lens,
Epithelium, glands, cilia of skin and caruncle,
Vitreous,
Eyelid skin, glands and cilia,
Route for tear production and drainage (lacrimal gland and canalicular system)
Derivation of ocular tissue – mesoderm
Use the mnemonic If PROVEN CLEVER, (SEE TV) iii. Mesoderm: Schlemm’s canal, Endothelium of all vessels, Extraocular muscle fibers, Temporal sclera, Vitreous
Derivation of ocular tissue - neural crest
iv. Neural Crest: Everything else (lots of Cs)
Corneal stroma
Corneal endothelium
Trabecular meshwork
Iris connective tissue
Ciliary muscles and ganglion
ON meningeal sheaths,
Choroid
Melanocytes
Sclera (temporal portion = mesoderm)
EOM sheaths and tendons
Orbital bones (all midline and inferior & parts of orbital roof and lateral rim)
orbital connective tissue
Cartilage
Schwann cells
muscular layer and sheaths of blood vessels
hyaloid artery is a branch of which artery in the developing eye?
HYAlOID ARTERY: HY A:artery L, O:ophthalmic, I: think I looks like a number 1 which means first primitive D: dorsal
primitive dorsal ophthalmic artery
What is the “Fibrillenstruktur neuromuscular junction” and for what type of movement are they responsible?
Fibrillenstruktur muscles use en plaque neuromuscular junctions and are responsible for saccadic movements.
Felderstruktur muscles use en grappe neuromuscular junctions and are responsible for smooth pursuit movements.
Felder grapples with smooth movement (smooth wine/grapes)
