False
The muscle spindle aparatus serves as a muscle length decector
True
A greater bending of the stereocilia will increase the frequency of action potentials and will be perceived as a louder sound

The larger the cross-sectional area of a type of vessel, the higher the blood pressure
False
Urine collects in the urinary bladder prior to entry into the urethra

An increased GFR leads to an increse in urine production
True
Adrenal medulla hormones prolong the effects of sympathetic nerves
True
The measurement of a particular antigen by an agglutination reaction is called an immunoassay
True
ADH secretion is stimulated when osmoreceptors in the hypothalamus detect a decrease in blood osmolality
