What is the enzyme produced by cellular respiration in skeletal muscle that produces energy required for a muscle to move?
Adenosine triphosphate (ATP)
When a muscle runs out of ATP, what waste produce causes the tired and sometimes burning feeling of muscle fatigue?
Pairs of muscles acting or working together to bring about and stabilize muscle movement?
What is the strongest tendon in the body and attaches the calf muscle to the calcaneus (heel)?
White, fibrous cordlike structure that serves to connect muscle to bone?
What is a neurotransmitter (chemical) used by nerve endings to send an impulse across a synapse to another nerve, and stimulates the next muscle to contract?
What is it when muscle tension increases, but the muscle does not shorten for example pushing against a wall or pushing an immoveable object?
Place where muscle fiber and nerve endings meet, and a motor neuron comes in contact with a skeletal muscle cell?
Abnormal muscle movement or contraction such as twitching and cramping of a muscle caused by low serum (blood) calcium level?
Intercalated disks & involuntary muscle that is striated and found in the heart walls?
The point at which a muscle begins or is attached to a bone - More-fixed muscle anchored to a nonmoving bone?
A bruise; does not require surgery?
Records strength of muscle contraction resulting from electrical stimulation to muscle or procedure that records the electrical activity of muscles?
Muscle and tendon inflammation; same as fibromyalgia (causes chronic pain in muscles and soft tissue surrounding joints. Complaints of dull, aching pain throughout body, stiffness, fatigue, depression, and disturbed sleep.)?
Protrusion (bulging)of an organ or part of an organ through a weakness in a muscle wall?
Autoimmune disease affecting normal transmission of nerve impulses along with progressive weakness and atrophy of muscles (usually starting with facial and eye muscles)?
T or F
All muscle activity is influenced by the nervous system
T or F
Muscles work in teams to pull, but cannot push.
The 3 main functions of muscles are:
When an individual lifts a heavy object, the muscles shorten and thicken as they contract, this is known as what kind of contraction?
This type of abnormal contraction is caused when the muscle is stimulated in a series of "rapid fire" impulses?
What is a jerky response to a stimulus?
"Striated" (zebra stripped) or "voluntary" (conscious choice to move) are examples of which muscle, that attach to bone?
"Involuntary" (unconscious movement) or "visceral" are which type of muscle?
What muscle is "striated" in appearance but "involuntary" or smooth muscle in function?
Skeletal muscles are voluntary muscles that under a microscope are "zebra striped" or have light and dark bands of muscle fibers. These are known as what?
What is the muscle responsible for movement when a group of muscles is contracting at the same time?
Prime mover or agonist
The point at which a muscle begins or is attached to a bone is its origin. Where it ends is known as what point?
Quad attachments means?
What is a deficiency of skeletal muscle, that is as serious a health threat as osteoporosis and involves not only losing strength and endurance, but also gaining fat tissue?
What disease is caused by the bacterium Clostridium tetani, which enters the body through a deep, open wound. Also known as "lockjaw"?
