Which layer of the skin is known as the "true skin"?
Answer: Dermis
The dermis is often referred to as the "true skin" because it contains the majority of the skin's structures, including blood vessels, nerves, hair follicles, and glands. It provides strength, elasticity, and nourishment to the epidermis, playing a crucial role in the skin's overall function and health.
What is the primary function of the sebaceous glands?
Answer: Secrete sebum
Sebaceous glands are exocrine glands found in the skin, primarily associated with hair follicles. Their main function is to produce and secrete an oily substance called sebum, which lubricates the skin and hair, preventing dryness and providing a protective barrier.
Which part of the hair structure is responsible for hair growth?
Answer: Hair bulb
The hair bulb is the lowest part of the hair strand, a thickened, club-shaped structure that forms the base of the hair follicle. It contains the dermal papilla, which is rich in blood vessels and nerves, supplying nutrients essential for the active growth and formation of new hair cells.
What is the largest bone in the human body?
Answer: Femur
The femur, or thigh bone, is the longest and strongest bone in the human body. It extends from the hip to the knee, supporting the body's weight and facilitating movement of the leg. Its robust structure is essential for locomotion and maintaining an upright posture.
Which of the following is NOT part of the central nervous system?
Answer: Peripheral nerves
The central nervous system (CNS) consists of the brain and spinal cord, which are responsible for processing information and coordinating bodily functions. Peripheral nerves, on the other hand, are part of the peripheral nervous system (PNS), extending from the CNS to the rest of the body to transmit sensory and motor signals.
