Question 1 of 5
The patient with apraxia cannot:
Correct Answer: B
Rationale: Carry out an imagined act is the correct answer because apraxia is a motor disorder characterized by the inability to perform purposeful movements, despite having the physical ability and desire to do so. This condition results from damage to the parietal lobe or other areas involved in motor planning.
Question 2 of 5
A squid axon is placed on stimulating electrodes, and an intracellular electrode is inserted and connected through a cathode-ray oscilloscope (CRO) to an indifferent electrode. When the axon is stimulated, the latent period is 1.5 ms. The intracellular electrode is 6 cm form the anode of the simulator and 4.5 cm from the cathode of the simulator. What is the conduction velocity of the axon.
Correct Answer: B
Rationale: The conduction velocity is calculated as the distance traveled divided by the time taken. Here, the distance between the anode and cathode is 6 cm + 4.5 cm = 10.5 cm (0.105 m). The time taken is the latent period of 1.5 ms (0.0015 s). Thus, conduction velocity = 0.105 m / 0.0015 s = 70 m/s. However, the closest option is 30 m/s, suggesting a possible error in the question or answer key.
Question 3 of 5
Anti-diuretic hormone (ADH):
Correct Answer: B
Rationale: ADH is synthesized in the hypothalamus and released by the posterior pituitary via neurosecretion. Its secretion is increased by high plasma osmolarity or low blood volume. ADH increases water reabsorption in the distal convoluted tubule and collecting ducts by increasing their permeability to water.
