Muscle structures
A bundle of muscle fibers enclosed by connective tissue, specifically perimysium.
What is fascicle
Muscle cell is stimulated by a nerve contract
What is excitability
This muscle is attached to bone.
What is skeletal muscle
A painful muscle spasm caused by heavy exercise, dehydration, extreme cold, low blood glucose or lack of blood flow.
What are cramps
What requires oxygen, begins with a glucose molecule and is performed by mitochondria.
What is aerobic respiration
A bundle of fascicles
What are muscles
A muscle is stretched, it will return to its original shape.
What is elasticity
Muscle that is located in the heart.
What is cardiac
An autoimmune disorder where antibodies attack the acetylcholine receptors in the neuromuscular junction.
What is myasthenia gravis
Name the functions of the muscular system.
What is movement, stability, communication, heat production and control of body openings and passages.
A connective tissue layer that surrounds each individual muscle fiber.
What is endomysium
A muscle cell can shorten with force. Muscles can only pull; they cannot push
What is contractility
This muscle type is located in hollow organs and blood vessels.
What is smooth muscles
A disorder characterized by myalgia, fatigue, and pain in soft tissues, tendons and ligaments.
What is fibromyalgia.
Name the 3 basic lever system parts
What is resistance, effort and fulcrum
Connective tissue that protects/sheaths a fascicle
What is perimysium
The stimulation from the nerve moves quickly along the length of the muscle cell.
What is conductivity
This muscle type causes voluntary control.
What is skeletal
Term used for muscle pain.
What involves thick myofilaments grabbing thin myofilaments and pulling them toward the center of the sarcomere. As sarcomeres are shortened, so are the muscle cells.
What is sliding filament theory
Fibrous/elastic connective tissue that surrounds all the muscle.
These two muscle types have involuntary control
What is cardiac and smooth muscles
A type of muscular dystrophy that has a very rapid progression. It is caused by a defect in the gene that produces dystrophin.
What is Duchenne dystrophy
Increasing the tension in muscles without moving the arm, so it keeps the same length. Muscles bulge with the increased tension, but movement would have not resulted.
What is an isometric contraction
