What are flat sheets of tendons called?
aponeuroses
How many bones do most muscles attach to?
2 bones
Which skeletal muscle arrangement has the greatest potential for overall muscle shortening?
parallel sheets
What part of the bone does the tendon attach to?
periosteum
Which muscle tissue is voluntary and striated?
skeletal muscle
What is an example of a flexor/extensor pair?
biceps brachii (flexor) and triceps brachii (extensor)
Which muscle tissue is found in systems with autonomic function?
smooth muscle
What regulates smooth muscle contractions?
autonomic nervous system
Which end of the muscle is the less mobile attachment?
origin
What is the name of the sphincter between the stomach and small intestine?
pyloric sphincter
What type of pennate muscle attaches to a tendon on three or more sides?
multipennate
What type of pennate muscle attaches to a tendon on one side only?
unipennate
Why do smooth muscles in the eyes contract?
to adjust pupil size and lens thickness
What type of muscle pulls the limb toward the medial plane?
aDductors
What is the gastrocnemius for the stifle?
flexor
What type of pennate muscle attaches to a tendon on two sides?
bipennate
What are the four ways skeletal muscles are arranged?
parallel sheets, narrow bands, fusiform, or pennate (penniform)
Which skeletal muscle arrangement is the weakest?
parallel sheets
What is an example of a fusiform muscle?
biceps brachii
Where is the endomysium?
between individual muscle fibers
What are the three main functions of skeletal muscle?
locomotion, respiration, and heat production
What is the gastrocnemius for the hock (tarsus)?
extensor
What fibrous bands of collagen connect muscle to bone?
tendons
What is an example of a muscle that passes over more than one joint?
gastrocnemius
Does contraction require stimulation by a nerve?
no
Why do smooth muscles in the stomach and intestines contract?
mix and propel food along the GIT
Where is the perimysium?
surrounding each bundle of muscle fibers
What type of muscle decreases the angle between two bones?
flexor
What are the 3 types of muscle tissue?
skeletal, cardiac, smooth
Which end of the muscle is the more moveable attachment?
insertion

aBductors
What is an example of narrow bands?
sartorius muscles of the medial thigh
Which skeletal muscle arrangement is strongest?
pennate
How do skeletal muscles cause respiration?
by changing the volume of the thoracic cavity

piloerection
Which muscle tissue is involuntary and unstriated?
smooth muscle
What type of muscles encircle an opening?
sphincter
What does penniform mean?
feather like
Where is the epimysium?
around the entire muscle
Why do smooth muscles contract in the blood vessels?
to control distribution of blood
What are tendons composed of?
dense regular connective tissue in parallel bundles

flat muscles
