- b.The liver
- c.The lungs
- d.The heart
Answer: a
Explanation: The skin is the largest organ by surface area and weight, with three main layers: epidermis, dermis, and subcutaneous.
- 2. Anatomy & Sciences
The muscles that bend the wrist and fingers toward the palm are called:
- a.Adductors
- b.Extensors
- c.Flexors
- d.Abductors

- 10. Ethics & California Law
A California-licensed manicurist's scope of practice does NOT include:
- a.Performing a hand and foot massage that does not extend beyond the elbow or knee
- b.Polishing, shaping, and applying artificial nails and gel polish to fingernails and toenails
- c.Performing a facial chemical peel or extracting comedones from a client's face
- d.Applying nail-product remover such as acetone
Answer: c
Explanation: The Barbering and Cosmetology Act defines four license categories with different scopes. A manicurist may work on the hands, feet, and nails, including polish, artificial nails, gel, and a hand or foot massage that does not extend beyond the elbow or knee. Facial chemical peels and comedone extraction are esthetician (or full-cosmetologist) services that are OUTSIDE the manicurist scope and are prohibited for a manicurist under Bus. & Prof. Code §7321 (scope of manicurist license). Options A, C, and D are squarely within the manicurist scope. Stepping outside scope risks citation and license discipline.
