A hand-drawn style, easily reproducible medical diagram of direct laryngoscopy. Show a sagittal (side cross-section) view of the head and neck with clear labels. Include: the mouth open, laryngoscope blade inserted along the tongue, epiglottis being lifted, and the vocal cords visible at the glottic opening. Label key structures: tongue, epiglottis, vallecular, vocal cords/glottis, laryngoscope blade, trachea. Use simple black-and-white sketch lines, like a medical textbook illustration a student could easily reproduce by hand. Keep it clean and educational.

Here is a hand-drawn style diagram of direct laryngoscopy:

Key structures to remember when drawing or performing direct laryngoscopy:

Structure	Role
Tongue	Displaced leftward/upward by the blade
Vallecula	Space between tongue base and epiglottis; tip of Macintosh blade sits here
Epiglottis	Lifted indirectly (Mac blade) or directly (Miller blade) to expose glottis
Vocal cords	Target landmark — the glottic opening between them is where the ETT passes
Arytenoids	Posterior cartilages that form the posterior border of the glottis
Trachea	Inferior to glottis; ETT directed here

Quick sketch guide (how to reproduce it by hand):

Draw a simple side-profile of the head/neck with mouth open
Sketch the tongue as a large curved mass in the floor of mouth
Draw the laryngoscope handle outside the mouth, blade curving along the tongue
Add a leaf-shaped epiglottis at the tongue base, being lifted anteriorly
Show the vocal cords as two angled lines forming a "V" or triangle (glottic opening)
Draw the trachea as a tube descending from the glottis
Add a dashed line or arrow showing the ETT path through the cords into the trachea

Blade tip position:

Macintosh (curved blade): tip in the vallecula → lifts epiglottis indirectly
Miller (straight blade): tip goes under the epiglottis → lifts it directly

A hand-drawn style, easily reproducible medical diagram showing the view seen through a laryngoscope - the laryngoscopic view from above (bird's eye / operator's perspective). Show the circular field of view with the following structures clearly labeled: epiglottis at the top, left and right aryepiglottic folds on the sides, left and right vocal cords (true vocal cords) forming a V-shape in the center with the glottis (triangular opening) between them, false vocal cords (vestibular folds) above the true cords, arytenoid cartilages posteriorly, anterior commissure at the apex of the V, posterior commissure between the arytenoids, and the dark tracheal lumen visible through the glottic opening. Simple black and white sketch, like a medical textbook diagram a student can easily reproduce by hand. Clean labels with lines pointing to each structure.

Here is the laryngoscopic view — what you actually see when you look through the laryngoscope:

Structures visualised on laryngoscopy (anterior → posterior):

Structure	What you see
Epiglottis	Top of the field; leaf-shaped, lifted out of view by blade
Aryepiglottic folds	Two ridges running laterally from epiglottis to arytenoids
False vocal cords (vestibular folds)	Pink, lateral folds — do NOT adduct during phonation
True vocal cords	Pearly white, form a V-shape pointing anteriorly
Anterior commissure	Apex of the V, where cords meet anteriorly
Glottis	Triangular dark opening between the true cords — ETT goes here
Arytenoid cartilages	Paired, posterior; visible as small mounds behind the cords
Posterior commissure	Between arytenoids, posterior border of glottis
Subglottis / Trachea	Dark lumen visible through the glottis

Cormack-Lehane grading (how much of this view you get):

Grade	View
I	Full glottis visible
II	Only posterior commissure / arytenoids visible
III	Only epiglottis visible
IV	Not even epiglottis visible
