Portraits & Caricatures Facial Anatomy & Proportions 2 — Questions and Answers
Question 1: What is the orbicularis oculi muscle responsible for in facial expression?
- Moving the eyebrows upward
- Opening and closing the eyelids and producing eye squinting (Correct answer)
- Controlling the dilation of the pupils
- Lifting the corners of the mouth
Correct answer: Opening and closing the eyelids and producing eye squinting
The orbicularis oculi is a circular muscle surrounding the eye that closes the eyelid, squints the eye, and contributes to expressions like smiling and frowning around the eye area.
Question 2: The nasolabial fold runs between which two facial landmarks?
- From the inner corner of the eye down to the corner of the mouth
- From the corners of the nose down to the corners of the mouth (Correct answer)
- From the base of the nose to the chin
- From the outer edge of the nostril to the earlobe
Correct answer: From the corners of the nose down to the corners of the mouth
The nasolabial fold is the crease that runs from the outer edge of the nostrils down to the corners of the mouth, becoming more prominent with age and facial expressions.
Question 3: What is the glabella in facial anatomy?
- The fleshy lower part of the earlobe
- The smooth flat area between the eyebrows just above the nose (Correct answer)
- The prominence of the upper lip below the philtrum
- The hollow temple region at the side of the skull
Correct answer: The smooth flat area between the eyebrows just above the nose
The glabella is the smooth bony prominence between the eyebrows above the nasal bridge, an important landmark for placing the brows correctly in portraits and for understanding skull structure.
Question 4: How does the nose width typically relate to eye placement in classical proportion?
- The nose is as wide as one eye-width
- The nose width equals the distance between the outer corners of both eyes
- The nose width equals the distance between the inner corners of the eyes (one eye-width of space) (Correct answer)
- The nose is exactly half as wide as the mouth
Correct answer: The nose width equals the distance between the inner corners of the eyes (one eye-width of space)
The wings of the nose align approximately with the inner corners of the eyes, meaning the nose width equals the inter-eye gap (about one eye-width), a key proportional check in portrait drawing.
Question 5: In caricature, how is the forehead typically manipulated to suggest intellectual character?
- It is always reduced to emphasize physical features
- It may be enlarged or heightened to suggest intelligence or cerebral qualities (Correct answer)
- It is given a receding hairline regardless of the subject
- It is eliminated from the composition to focus on the face
Correct answer: It may be enlarged or heightened to suggest intelligence or cerebral qualities
Caricaturists often enlarge the forehead to connote intelligence or wisdom, playing on the cultural association between a high forehead and cerebral capacity.
Question 6: What is the mastoid process and why is it relevant to portrait artists?
- A muscle controlling jaw movement that affects the chin's shape in profile
- A bony protrusion behind the ear that affects skull shape and sternocleidomastoid muscle attachment (Correct answer)
- A term for the cartilage of the outer ear used for proportion reference
- The bony ridge above the eye socket that defines brow structure
Correct answer: A bony protrusion behind the ear that affects skull shape and sternocleidomastoid muscle attachment
The mastoid process is a prominent bony bump behind the earlobe; understanding it helps portrait artists accurately render the back of the skull and the neck's attachment in three-quarter and profile views.
Question 7: The mentalis muscle is primarily associated with which area of the face?
- The forehead, controlling horizontal furrows
- The chin, controlling lip and chin movement in expressions like pouting (Correct answer)
- The cheeks, providing the apple of the cheek fullness
- The nose, controlling nostril flaring
Correct answer: The chin, controlling lip and chin movement in expressions like pouting
The mentalis is a paired muscle of the chin that elevates and wrinkles the chin skin, contributing to pouting, doubt expressions, and the dimpling seen in many chin areas.
