BIO 251 EXAM 3 STUDY GUIDEA muscle fiber can be innervated by multiple motor neurons. 
a) True 
b) False f 
The contraction time of a skeletal muscle is the time between initiation of stimulation and 
peak contraction of the muscle. 
a) True 
b) False f 
During contraction of all types of muscle cells, Ca++ initiates contraction by entering the 
cytoplasm of the muscle cell by the process of facilitated diffusion. 
a) True

Graded Potentials, Action Potentials&SynapseGraded Potentials - correct answer A small deviation from the RMP that makes the membrane either more polarized (more negative inside=hyperpolarizing) or less polarized (less negative inside=depolarizing). 
 
Hyperpolarizing Graded Potentials - correct answer When the response makes the membrane more polarized (more negative inside). Occurs in soma and dendrites of a neuron. 
 
Depolarizing Graded Potentials - correct answer When the response makes the...
