It is often said that it takes more muscles to frown than to smile. This is a well-known piece of conventional wisdom, but is it true? It turns out that the answer is more complicated than a simple yes or no. While there is one main muscle always in use when smiling – the zygomaticus major – there are groups of muscles necessary for both smiling and frowning.

What You'll Learn
It takes 43 muscles to frown, and only 17 muscles to smile
The Zygomaticus Major is the main muscle responsible for smiling. It works in conjunction with up to 43 other facial muscles to produce a wide range of smiles, from a sly grin to a full, toothy smile. The seventh cranial nerve, also known as the facial nerve, controls most of these muscles. This nerve begins at the cerebral cortex and exits the skull in front of the ears, splitting into five primary branches that reach different areas of the face.
Frowning also involves the use of multiple muscles, although the exact number can vary. While some sources claim that it takes 43 muscles to frown, this may include muscles that are not always active during a frown. The specific muscles involved in frowning include the corrugator supercilii, which draws the eyebrows together, and the orbicularis oculi, which surrounds the eye and is responsible for the "crow's feet" wrinkles that can form at the corners of the eyes during a frown.
Regardless of the exact number of muscles involved, the core message of the adage remains valid. Smiling generally requires less effort than frowning, so it's a good reminder to choose a positive outlook whenever possible. However, it's important to remember that the impact of a smile or a frown goes beyond the number of muscles involved. Cultural context, personal expression, and non-verbal cues all play a role in how these expressions are interpreted.

The zygomaticus major is the smiling muscle
It takes 43 muscles to smile, and the zygomaticus major is the main muscle responsible for our smile. It is known as the 'smiling muscle' and works in conjunction with up to 43 other facial muscles to provide a wide array of smiles. The zygomaticus major and minor work to pull the orbicularis oris upward to form a smile.
The zygomaticus major is one of the muscles controlled by the seventh cranial nerve, also known as the facial nerve. This nerve begins at the cerebral cortex, emerging from the skull in front of the ears. It then separates into five branches, each connecting to a different part of the face, which is why we have such a wide variety of possible expressions. The branches control the movement of the muscles that control the mouth.
The zygomaticus major is the muscle that allows us to smile, but it is just one part of a complex system of muscles and nerves that enable us to express a range of emotions through facial expressions. While smiling may be viewed as a sign of friendliness, the configuration of the zygomaticus major and other facial muscles can create a million different smile configurations, from a sly grin to a full, toothy smile.

The seventh cranial nerve controls most of the 43 muscles we use to smile
Smiling is viewed across cultures as a sign of friendliness, especially when greeting someone. It takes 17 muscles to smile, and the Zygomaticus Major is the main muscle used when smiling. This muscle is also known as the 'smiling muscle' and is responsible for pulling the orbicularis oris upward to form a smile.
The seventh cranial nerve, also known as the facial nerve, controls most of the 43 muscles we use to smile. This nerve begins at the cerebral cortex, emerging from the skull in front of the ears. From there, it separates into five branches, each connecting to a different part of the face. These branches are known as the temporal, zygomatic, buccal, mandibular and cervical.
The seventh cranial nerve controls the movement of the muscles that control the mouth, allowing for a wide variety of possible expressions. While smiling, the nerve works in conjunction with the zygomaticus major and minor to form a smile. The zygomaticus major is the primary muscle responsible for our smile, but it works alongside other muscles to provide a wide array of smiles, from sly grins to full, toothy smiles.

The facial nerve has five primary branches
Smiling and laughing are complex actions that involve the use of many muscles. While there is one main muscle always in use when smiling — the Zygomaticus Major — there are groups of muscles necessary for both smiling and laughing. The Zygomaticus Major is known as the 'Smiling Muscle' and is most responsible for our smile. It works in conjunction with up to 43 other facial muscles to provide a wide array of smiles.
The facial nerve, also known as the seventh cranial nerve, has five primary branches: temporal, zygomatic, buccal, mandibular and cervical. These branches reach different areas of the face and enervate muscles that allow the face to twist and contort into a variety of expressions. The facial nerve begins at the cerebral cortex, emerging from the skull in front of the ears. From there, it separates into the five branches, each of which connects to a different part of the face.
The specific muscles controlled by the facial nerve include the muscle of expression, and especially the zygomaticus major and minor, which work to pull the orbicularis oris upward to form a smile. The zygomaticus minor is also involved in the act of laughing, as it pulls the corners of the mouth upward.
The facial nerve is responsible for controlling the movement of the muscles that control the mouth, allowing for a wide variety of possible expressions. This includes not only smiling and laughing but also frowning and other facial expressions. The facial nerve and its five primary branches play a crucial role in our ability to communicate and express emotions through facial movements.

The facial nerve begins at the cerebral cortex
Smiling is said to take the use of 17 or 43 muscles, while laughing is said to take 43. The facial nerve, also known as the seventh cranial nerve, begins at the cerebral cortex and exits the skull in front of the ears. It then divides into five primary branches: the temporal, zygomatic, buccal, mandibular and cervical. These branches reach different areas of the face and allow for a wide variety of facial expressions. The facial nerve carries nerve fibres that control facial movement and expression, as well as nerves involved in taste and tear production. The nerve begins in the brainstem and travels through the base of the skull near the vestibulocochlear nerve, which is responsible for hearing and balance.
