QUESTIONS AND
ANSWERS 2026 - 2027
With respect to the lateral corticospinal tract (LCST) the cell bodies of
the upper motor neurons are located in the ______________. -
ANSWERS--primary motor cortex
-precentral gyrsus
Motor Unit - ANSWERS-A motor unit is defined as a lower motor
neuron and the group of muscle fibers it innervates.
Muscle cells - ANSWERS--Muscle cells are multinucleated
-Muscle cells contain t-tubules
-The plasma membrane of muscle cells is called the sacrolemma
-The sarcoplsamic reticulum contains a high concentration of Ca2+
Ca2+ binds to ____________________, which rolls
__________________ out of the way. This allows myosin to bind the
myosin binding sites located on the actin thin filaments. - ANSWERS-
