BIO 201 EXAM 5 WITH CORRECT
ANSWERS 2025
Sympathetic Nervous System correct answers >> What
portion of the nervous system prepares the body for stressful or
emergency situations,
What are the three types of muscle tissues? correct answers
>> Cardiac Muscles, Smooth Muscles, and skeletal muscle
Describe cardiac muscle correct answers >> Cardiac muscle
cells are located in the walls of the heart, appear striated, and are
under involuntary control.
Describe smooth muscle correct answers >> Smooth muscle
fibers are located in walls of hollow visceral organs, except the
heart, appear spindle-shaped, and are also under involuntary
control.
Describe skeletal muscle correct answers >> Skeletal muscle
fibers occur in muscles which are attached to the skeleton. They
are striated in appearance and are under voluntary control.
What are neurotransmitters? correct answers >> chemical
messengers that transmit a signal from a neuron across the
synapse to a target cell. They are chemical substances made by
the neuron specifically to transmit a message
, What is the fascia and aponeuroses? correct answers >> An
aponeurosis is made of layers of delicate, thin sheaths and allows
the body to be strong and stable. Aponeuroses can act as fascia.
Fascia is a fibrous tissue that envelopes muscles or organs, to
bind muscles together or to other tissues.
What is the sarcolemma and sarcoplasm? correct answers >>
Skeletal muscle fibers are long, multinucleated cells. The
membrane of the cell is the sarcolemma; the cytoplasm of the cell
is the sarcoplasm
What is the neuromuscular junction? correct answers >> a
synaptic connection formed between a motor neuron axon and a
muscle fiber. It is the site for the transmission of action potential
from nerve to the muscle
What is a synaptic cleft? correct answers >> A synaptic cleft
is a space that separates two neurons. It forms a junction
between two or more neurons and helps nerve impulse pass from
one neuron to the other.
Describe the sliding filament theory (short answer format)
correct answers >> The sliding filament theory describes the
process by which muscles contract. Muscle contraction occurs
through the relative sliding of two sets of filaments (actin and
myosin)
Explain cross bridge cycling (short answer format) correct
answers >> It is a series of events during which myosin heads
pull thin filaments toward the center of the sarcomere.
