Question

Transcribed Image Text:Smooth muscle cells have features that can be like Skeletal muscle, Cardiac muscle,
or that can be unique to smooth muscle cells themselves. Match the 3 options below
to the description of smooth muscle cells on the left.
do NOT possess
sarcomeres
do NOT possess troponin
or tropomyosin
neurotransmitters and
hormones regulate
contraction
different cells of the same
muscle type can contract or
relax in response to the
1. similar to skeletal muscle
same neurotransmitter
2. similar to cardiac muscle
possess gap junctions for
coordinating contraction of
multiple cells
3. unique to smooth muscle
can generate contraction
through an influx of Ca2+
across the plasma
membrane
use calmodulin and myosin
light-chain kinase to start
the cross-bridge cycle
make use of motor units to
control contraction
