Pankaj noticed that the veins in his hand collapsed (became flat) when his hand was 27 cm above his heart. Using the formula in his lab book, Pankaj calculated the gravitational pressure acting on the blood in his hand at this height to be 13 mmHg. Pankaj also calculated that the gravitational pressure acting on his arm when it was vertical to be 37 mm Hg. Which ONE of the following statements is CORRECT? a. Pankaj’s central venous pressure is approximately 37 mm Hg b. Pankaj’s central venous pressure is approximately 24 mm Hg c. The pressure exerted by blood within Pankaj’s central veins on the walls of those veins is approximately 13 mm Hg d. Pankaj’s central venous pressure is below the normal range e. It is not possible to conclude anything about Pankaj’s cardiovascular function without knowing how far above the ground his heart is
c. The pressure exerted by blood within Pankaj’s central veins on the walls of those veins is approximately 13 mm Hg
During the dive reflex experiment, one of your class members placed their face into icecold water. Select one CORRECT statement from the options below: a. The subject’s heart rate increased during submersion due to the stress of submersion b. Blood flow in the subject’s radial artery (where pulse was measured) stopped during submersion c. The subject’s pulse pressure increased during submersion d. The subject’s heart rate decreased during submersion e. The subject’s heart rate was constant throughout the experiment due to homeostasis
d. The subject’s heart rate decreased during submersion
Which of the following functions BEST describes those handled by the cerebral cortex region of the brain a. integrate sensory information, regulate temperature, feeding, reproduction, circadian rhythms b. olfaction, information processing, movements, emotions, memory c. rhythmic breathing, heart rate, blood pressure d. body posture, locomotion, breath-holding, integration e. integrate sensory information and responded to this information
b. olfaction, information processing, movements, emotions, memory
The field of view of is determined by the location of the eyes on an animal’s head. For a sheep, what would you estimate to be the “blind area” behind its head? a. 45 degrees b. 90 degrees c. 120 degrees d. 180 degrees e. 220 degrees
b. 90 degrees
. In one of the exercises in the sensory practical class, a student volunteer was placed in a swivel chair and asked to indicate the direction when rotated. In this exercise, which of the following sensory receptors detected the direction of rotation? a. Utricle b. Saccule c. Horizontal semicircular canal d. All 3 semicircular canals e. Both the utricle and saccule
c. Horizontal semicircular canal
In humans, 2-point discrimination is the ability to perceive 2 fine points pressed against the skin as 2 distinct points. In the practical class, the finger, the palm of the hand, the forearm and the calf were tested. Which one of the following correctly lists these regions from the greatest ability to discriminate between 2 points to the poorest ability to discriminate between 2 points? Greatest Poorest a. Forearm; finger; calf; palm b. Finger; calf; forearm; palm c. Palm; finger; calf; forearm d. Finger; palm; forearm; calf e. Palm; finger; forearm; calf
d. Finger; palm; forearm; calf
When light was shone into one eye the pupil in that eye constricted. This was the direct response. Which ONE of the following correctly describes the consensual response that was observed in the other eye? a. The pupil did not constrict or dilate b. The pupil dilated c. The pupil constricted to the same degree as in the direct response d. The pupil constricted to greater degree than in the direct response e. The pupil constricted, but to a lesser degree than in the direct response
e. The pupil constricted, but to a lesser degree than in the direct response
