Labeling
This muscle is the large muscle on the front of the upper arm, contracting with elbow flexion.
What is the biceps brachii?
This connective tissue connects muscle to bone.
What is a tendon?
The muscle that shortens to produce movement.
What is the agonist (prime mover)?
The word maximus in a muscle name refers to this characteristic.
What is size (largest)?
This type of muscle is voluntary and attached to bones.
What is skeletal muscle?
This muscle covers the shoulder and helps lift the arm.
What is the deltoid?
The basic contractile unit of muscle fibers.
What is a sarcomere?
This theory explains how actin and myosin slide past each other.
What is the sliding filament theory?
The muscle orbicularis oculi is named for this characteristic.
What is shape (circular)?
This muscle type is found in the heart.
What is cardiac muscle?
This muscle is located on the back of the upper arm and extends the elbow.
What is the triceps brachii?
The connective tissue surrounding an individual muscle fiber.
What is endomysium?
The energy molecule muscles use during contraction.
What is ATP?
The muscle temporalis is named for this characteristic.
What is location?
These muscles move food through the digestive system.
What are smooth muscles?
This large muscle on the back helps pull the arms downward.
What is the latissimus dorsi?
The area where a motor neuron meets a muscle fiber.
What is the neuromuscular junction?
This ion is released from the sarcoplasmic reticulum to trigger contraction.
What is calcium (Ca²⁺)?
The muscle flexor carpi radialis is named for this characteristic.
What is function/action?
This muscle function allows a muscle to decrease the angle between two bones, such as when you bend your elbow.
What is flexion?
This muscle lays under the calf and absorbs glucose well.
What are the soleus?
The protein that thick filaments are made of.
What is myosin?
This neurotransmitter is released from the motor neuron into the neuromuscular junction to stimulate a muscle fiber to contract.
What is acetylcholine?
The muscle sternocleidomastoid is named for this characteristic.
What is attachment points (origin/insertion)?
This muscle function moves a body part away from the midline of the body, like lifting your arm out to the side.
What is abduction?
