Cosmetology Test Anatomy and Physiology 3 — Questions and Answers
Question 1: Which bone forms the upper jaw and is the largest bone of the face?
- Mandible
- Maxilla (Correct answer)
- Zygomatic bone
- Nasal bone
Correct answer: Maxilla
The maxilla forms the upper jaw, the hard palate, and much of the floor and sides of the nasal cavity.
Question 2: The stratum granulosum is significant because it is where:
- New skin cells are produced by mitosis
- Keratinocytes begin to flatten and produce keratin granules (Correct answer)
- Melanocytes produce melanin pigment
- Langerhans cells first appear
Correct answer: Keratinocytes begin to flatten and produce keratin granules
In the stratum granulosum, cells accumulate keratohyalin granules and begin to lose their nuclei, preparing to become the outer protective layer.
Question 3: Which type of joint allows the greatest range of motion and is most common in the limbs?
- Fibrous joint
- Cartilaginous joint
- Synovial joint (Correct answer)
- Suture joint
Correct answer: Synovial joint
Synovial joints are freely movable and contain synovial fluid that lubricates the joint cavity.
Question 4: Lymph nodes function primarily to:
- Produce red blood cells
- Filter lymph fluid and activate immune responses (Correct answer)
- Regulate blood pressure
- Secrete digestive enzymes
Correct answer: Filter lymph fluid and activate immune responses
Lymph nodes trap pathogens and foreign particles from lymph fluid and house lymphocytes that mount immune responses.
Question 5: The temporalis muscle is involved in which primary movement?
- Raising the eyebrows
- Closing the mouth / chewing (Correct answer)
- Turning the head
- Compressing the cheeks
Correct answer: Closing the mouth / chewing
The temporalis muscle elevates the mandible (closes the jaw) and is a major muscle of mastication.
Question 6: Melanocytes are primarily located in which layer of the epidermis?
- Stratum corneum
- Stratum lucidum
- Stratum basale (Correct answer)
- Stratum spinosum
Correct answer: Stratum basale
Melanocytes reside in the stratum basale and produce melanin that is transferred to surrounding keratinocytes for UV protection.
Question 7: The primary function of the lymphatic system relevant to cosmetology is:
- Oxygenating skin cells directly
- Removing waste and excess fluids from tissues (Correct answer)
- Producing new skin cells
- Synthesizing vitamin D
Correct answer: Removing waste and excess fluids from tissues
The lymphatic system drains interstitial fluid and waste products from tissues, which is why lymphatic drainage massage reduces puffiness.
