Biology 224: Lab Exam 1 Questions With Complete
Solutions
Define cockroach:
1. Metathoracic Legs
2. Coxa
3. Trochanter
4. Femur
5. Tibia
6. Tarsus Correct Answers 1. hind legs
2. upper portion of leg
3. acts like a knee, allows bending of leg
4. resembles thigh
5. resembles shin
6. acts like ankle and foot
Define firing rate. Correct Answers Action Potentials / Second.
Define mechanoreceptors. Correct Answers Specialized sensory
nerve cells that respond to touch, pressure, sound, movement,
and stretch; can detect both external and internal stimuli.
Define nervous system integration. Correct Answers The
generation of a motor output based on the sum of sensory inputs.
Define phasic. Correct Answers Rapidly adapting responses
typically associated with changes in intensity of a stimulus.
Define phasictonic. Correct Answers Burst of AP's followed
immediately by a large drop in firing rate that settles into a tonic
pattern as stimulus is maintained.
, Define proprioreceptors. Correct Answers Internal
mechanoreceptors that function to tell us info about muscle
position, contraction, movement, and place in space.
Define reaction time. Correct Answers The time from the start
of a signal to the response.
Define sensory receptor adaptation. Correct Answers A decline
of sensory receptor firing rate with prolonged duration.
Define stretch receptors. Correct Answers Used to detect the
position of the limb as the subject moves. As the limb is moved
from a neutral position, sensory neurons increase rate at which
they generate AP's.
Define tonic. Correct Answers Slowly adapting responses
typically associated with a prolonged stimulus.
Define visual-motor learning. Correct Answers The process of
increasing the accuracy, speed, and coordination of tasks
involving hand-eye coordination the more often we perform
them.
Define:
1. Setae
2. Hair plates
3. Campaniform sensilla
4. Chordotonal organs Correct Answers 1. mechanoreceptor;
short hair
2. mechanoreceptor; clusters of hairs
