- The forehead muscles, frontalis and occipitalis, are named after the frontal and occipital regions.
- The orbicularis oculi muscle encircles the eye, allowing eyelid closure.
- The corrugator supercilii and depressor supercilii muscles are named after their actions on the eyebrows.
- Extraocular muscles include rectus and oblique muscles that move the eye in different directions.
- The levator palpebrae superioris lifts the upper eyelid, while the superior tarsal muscle assists in this action.

Tongue muscles: intrinsic and extrinsic functions
- The tongue muscles consist of intrinsic muscles that change the tongue's shape and extrinsic muscles that move the tongue within the mouth, with the extrinsic muscles named based on their attachments, such as the Styloglossus connecting the skull's styloid process to the tongue.
- Intrinsic tongue muscles are named according to the direction of their fibers, like the verticalis for vertical fibers and transversus for side-to-side fibers, with the superior longitudinal muscle housing taste buds and nerve endings on top, while the inferior longitudinal muscle is located underneath.
