What hormone is important in milk production and maintaining lactation?
- A. Estrogen
- B. Oxytocin
- C. Prolactin
- D. Adrenaline
Correct Answer: C
Rationale: Prolactin is the correct answer because it is the hormone produced by the pituitary gland that stimulates milk production in the mammary glands. During lactation, prolactin levels remain elevated to ensure a continuous supply of milk. While oxytocin is involved in milk ejection, prolactin is primarily responsible for milk synthesis and maintenance of lactation.
The brain is protected by:
- A. the meninges.
- B. a cushion of fluid.
- C. the bony skull.
- D. All of the above.
Correct Answer: D
Rationale: The brain is protected by multiple layers of defense, including the meninges (protective membranes), cerebrospinal fluid (a cushioning fluid), and the bony skull. The meninges consist of three layersâ€â€dura mater, arachnoid mater, and pia materâ€â€that provide structural support and protection. Cerebrospinal fluid surrounds the brain and spinal cord, acting as a shock absorber. The skull provides a rigid barrier against physical injury. Together, these structures safeguard the brain from damage.

Nerve cells form long projections called ________.
- A. soma
- B. axons
- C. dendrites
- D. synapses
Correct Answer: B
Rationale: The correct answer is B: axons. Nerve cells form long projections called axons to transmit electrical impulses away from the cell body. Axons are essential for communicating signals between different parts of the nervous system. Soma (A) refers to the cell body of the neuron, dendrites (C) are short, branched extensions that receive signals, and synapses (D) are the junctions where neurons communicate with each other, not the long projections themselves. Therefore, axons are the correct choice for the long projections formed by nerve cells.
