Activating which of the following ultrasound functions will cause the largest change in beam intensity?

Blood is flowing toward a 7MHz transducer; you expect the reflected frequency to be _______ 7MHz.

How do the microbubbles in an ultrasound contrast agent change the image?

The motion of particles in a fluid is sometimes observed in an intense ultrasound beam. This is termed:

On some sonographic equipment, adjusting the compression will affect which of the following processes?

Axial resolution is normally better than lateral resolution.

Refer to Figure 9.  Tissue sections A, B, and C are all from reproductive organs that play an important role in gamete formation.  Identify which cell is the earliest ‘primary’ form of the human female gamete: [a] (Pick a number from 1 through 10 on the figure.) Identify which cell converts androgens into estrogen to aid female gamete production: [b]  (Pick a number from 1 through 10 on the figure.)

Refer to Figure 9.  Use the models on the right side of this figure to complete the blanks identifying organs or structures of the reproductive system with the following functions. Include the name AND the number from the figure for full credit! Be specific!   This organ stores sperm prior to ejaculation: [a] This organ fills with blood during female arousal: [b] This structure can be cut to prevent female fertility: [c] This organ is the site where semen is often deposited during intercourse: [d] This gland produces a lubricating substance during male arousal: [e]

Refer to Figure 6.  This figure shows multiple organs of the digestive tract located in the abdominal cavity, but mechanical digestion begins in the mouth.  Name the specific accessory structures in the mouth that helps by crushing and grinding foods: [a] Be specific! How many of this specific structure are in the ‘normal’ mouth? [b] Hint: top & bottom!
