BIOL 473 Theory Test 1

Five senses

Adaptation definition

Proprioreceptiors

Mechanoreceptor that senses gentle pressure

Receptive field

Order from most localization to least: forearm, fingertip, wrist, palm

What determines tactile sensitivity for a given area

Penny experiment: why is pressure sensation soon lost?

What temperatures are thermoreceptors sensitive to?

Homeostatic thermoreceptors

Do warm temp. receptors transmit absolute or relative information about temperatures

Define reflexes

Steps of knee jerk reaction

Are muscle stretches mono- or polysynaptic

Grey matter

Grey matter: Posterior horn

Grey matter: lateral horn

Grey matter: Anterior (ventral) horn

Roots: posterior (dorsal) root

Roots: dorsal root ganglion

Roots: Anterior (ventral)

When the volunteer performed Jendrassik maneuver, how did the knee-jerk reflex change?

What does the effect of the Jendrassik maneuver indicate about neural pathways involved in simple reflexes?

Why do you multiple the distance between patellar tendon and sacrum by two

Would you expect the conduction velocity to be the same or different with Jendrassik maneuver?

Consider the two volunteers: Liam is 1.8m (5.9ft) tall and Jacqui is 1.4m (4.6ft) tall. Which volunteer will have a faster response time

Why is it important that neurons in this reflex are myelinated?

Guillain-Barre syndrome is a demyelinating disease caused by infection. People with this will have loss of knee-jerk reaction. Why is this true?

Myopia

Hyperopia

Presbyopia

Astigmatism

Conduction deafness

Sensorineural deafness

Weber test

Rinne test

Weber/Rinne example:
Participant 1 lateralizes left for the Weber test. After the Rinne test, they report they can hear the tuning fork on the left side. This person has ______deafness in the ________ear

What do the semicircular canals detect

What are the three doses of drugs that will be given

What drugs can be given to reverse the effects of xylazine and bupivacaine

Preparation of the rat

disinfection order

Three layers of the abdominal wall

Which side receives oxygenated blood

Where does blood go after left ventricle

Which side of the heart receives deoxygenated blood

Where does the blood go after it is received in the right side of the heart

Papillary muscles

Chordae muscles

Blood flow through the heart

What is ultrasound

Hyperechoic

Anechoic

Isoechoic

Hypoechoic

List the following structures from closest to farthest from the probe: liver, gallbladder, abdominal muscles

True or false: Organs have homogenous ethnogenicities

What axis are we viewing the heart from

Which probes do you use for: heart, abdomen, and neck

What would happen to the blood pressure in the brain if the internal jugular vein did not change during the Valsalva maneuver

What are the ethnogenicities of the kidney

When the left ventricle is contracting, which valve is open

When the left ventricle is relaxed, which valve is open?

Do the ends of the leaflets of the valves ever touch
