Investing layer Pretracheal layer Prevertebral layer
29
# Between the Anterior and posterior Fontanelle which fuses first and what is the timeline
The Posterior fontanelle( is the first to close(6-8 weeks), the Anterior fontanelle is the last to close(18-24 months )
30
What is the Lacrimal apparatus
It is a system of structures responsible for the production, distribution amd collection of tears
31
What structure drains tears from the lacrimal duct, and where does it drain into
The Nasolacrimal sac and it drains into the inferior nasal meatus
